The Judicial Labyrinth for Scientific Evidence

October 3rd, 2018

The real Daedalus (not the musician), as every school child knows, was the creator of the Cretan Labyrinth, where the Minotaur resided. The Labyrinth had been the undoing of many Greeks and barbarians, until an Athenian, Theseus, took up the challenge of slaying the Minotaur. With the help of Ariadne’s thread, Theseus solved the labyrinthic puzzle and slayed the Minotaur.

Dædalus is also the Journal of the American Academy of Arts and Sciences. The Academy has been, for over 230 years, addressing issues issues in both the humanities and in the sciences. In the fall 2018 issue of Dædalus (volume 147, No. 4), the Academy has published a dozen essays by noted scholars in the field, who report on the murky interface of science and law in the courtrooms of the United States. Several of the essays focus on sorry state of forensic “science” in the criminal justice system, which has been the subject of several critical official investigations, only to be dismissed and downplayed by both the Obama and Trump administrations. Other essays address the equally sorry state of judicial gatekeeping in civil actions, with some limited suggestions on how the process of scientific fact finding might be improved. In any event, this issue, “Science & the Legal System,” is worth reading even if you do not agree with the diagnoses or the proposed therapies. There is still room for a collaboration between a modern day Daedalus and Ariadne to help us find the way out of this labyrinth.

Carl Cranor’s Conflicted Jeremiad Against Daubert

September 23rd, 2018

Carl Cranor’s Conflicted Jeremiad Against Daubert

It seems that authors who have the most intense and refractory conflicts of interest (COI) often fail to see their own conflicts and are the most vociferous critics of others for failing to identify COIs. Consider the spectacle of having anti-tobacco activists and tobacco plaintiffs’ expert witnesses assert that the American Law Institute had an ethical problem because Institute members included some tobacco defense lawyers.1 Somehow these authors overlooked their own positional and financial conflicts, as well as the obvious fact that the Institute’s members included some tobacco plaintiffs’ lawyers as well. Still, the complaint was instructive because it typifies the abuse of ethical asymmetrical standards, as well as ethical blindspots.2

Recently, Raymond Richard Neutra, Carl F. Cranor, and David Gee published a paper on the litigation use of Sir Austin Bradford Hill’s considerations for evaluating whether an association is causal or not.3 See Raymond Richard Neutra, Carl F. Cranor, and David Gee, “The Use and Misuse of Bradford Hill in U.S. Tort Law,” 58 Jurimetrics 127 (2018) [cited here as Cranor]. Their paper provides a startling example of hypocritical and asymmetrical assertions of conflicts of interests.

Neutra is a self-styled public health advocate4 and the Chief of the Division of Environmental and Occupational Disease Control (DEODC) of the California Department of Health Services (CDHS). David Gee, not to be confused with the English artist or the Australian coin forger, is with the European Environment Agency, in Copenhagen, Denmark. He is perhaps best known for his precautionary principle advocacy and his work with trade unions.5

Carl Cranor is with the Center for Progressive Reform, and he teaches philosophy at one of the University of California campuses. Although he is neither a lawyer nor a scientist, he participates with some frequency as a consultant, and as an expert witness, in lawsuits, on behalf of claimants. Perhaps Cranor’s most notorious appearance as an expert witness resulted in the decision of Milward v. Acuity Specialty Products Group, Inc., 639 F.3d 11 (1st Cir. 2011), cert. denied sub nom., U.S. Steel Corp. v. Milward, 132 S. Ct. 1002 (2012). Probably less generally known is that Cranor was one of the founders of an organization, the Council for Education and Research on Toxics (CERT), which recently was the complaining party in a California case in which CERT sought money damages for Starbucks’ failure to label each cup of coffee sold as known to the State of California as causing cancer.6 Having a so-called not-for-profit corporation can also be pretty handy, especially when it holds itself out as a scientific organization and files amicus briefs in support of reversing Daubert exclusions of the founding members of the corporation, as CERT did on behalf of its founding member in the Milward case.7 The conflict of interest, in such an amicus brief, however, is no longer potential or subtle, and violates the duty of candor to the court.

In this recent article on Hill’s considerations for judging causality, Cranor followed CERT’s lead from Milward. Cranor failed to disclose that he has been a party expert witness for plaintiffs, in cases in which he was advocating many of the same positions put forward in the Jurimetrics article, including the Milward case, in which he was excluded from testifying by the trial court. Cranor’s lack of candor with the readers of the Jurimetrics article is all the more remarkable in that Cranor and his co-authors give conflicts of interest outsize importance in substantive interpretations of scholarship:

“the desired reliability for evidence evaluation requires that biases that derive from the financial interests and ideological commitments of the investigators and editors that control the gateways to publication be considered in a way that Hill did not address.”

Cranor at 137 & n.59. Well, we could add that Cranor’s financial interests and ideological commitments might well be considered in evaluating the reliability of the opinions and positions advanced in this most recent work by Cranor and colleagues. If you believe that COIs disqualify a speaker from addressing important issues, then you have all the reason you need to avoid reading Cranor’s recent article.

Dubious Scholarship

The more serious problem with Cranor’s article is not his ethically strained pronouncements about financial interests, but the dubious scholarship he and his colleagues advance to thwart judicial gatekeeping of even more dubious expert witness opinion testimony. To begin with, the authors disparage the training and abilities of federal judges to assess the epistemic warrant and reliability of proffered causation opinions:

“With their enhanced duties to review scientific and technical testimony federal judges, typically not well prepared by legal education for these tasks, have struggled to assess the scientific support for—and the reliability and relevance of—expert testimony.”

Cranor at 147. Their assessment is fair but hides the authors’ cynical agenda to remove gatekeeping and leave the assessment to lay juries, who are less well prepared for the task, and whose function ensures no institutional accountability, review, or public evaluation.

Similarly, the authors note the temporal context and limitations of Bradford Hill’s 1965 paper, which date and limit the advice provided over 50 years ago in a discipline that has changed dramatically with the advancement of biological, epidemiologic, and genetic science.8 Even at the time of its original publication in 1965, Bradford Hill’s paper, which was based upon an informal lecture, was not designed or intended to be a definitive treatment of causal inference. Cranor and his colleagues make no effort to review Bradford Hill’s many other publications, both before and after his 1965 dinner speech, for evidence of his views on the factors for causal inference, including the role of statistical testing and inference.

Nonetheless, Bradford Hill’s 1965 paper has become a landmark, even if dated, because of its author’s iconic status in the world of public health, earned for his showing that tobacco smoking causes lung cancer,9 and for advancing the role of double-blind randomized clinical trials.10 Cranor and his colleagues made no serious effort to engage with the large body of Bradford Hill’s writings, including his immensely important textbook, The Principles of Medical Statistics, which started as a series of articles in The Lancet, and went through 12 editions in print.11 Hill’s reputation will no doubt survive Cranor’s bowdlerized version of Sir Austin’s views.

Epidemiology is Dispensable When It Fails to Support Causal Claims

The egregious aspect of Cranor’s article is its bill of particulars against the federal judiciary for allegedly errant gatekeeping, which for these authors translates really into any gatekeeping at all. Cranor at 144-45. Indeed, the authors provide not a single example of what was a “proper” exclusion of an expert witness, who was contending for some doubtful causal claim. Perhaps they have never seen a proper exclusion, but doesn’t that speak volumes about their agenda and their biases?

High on the authors’ list of claimed gatekeeping errors is the requirement that a causal claim be supported with epidemiologic evidence. Although some causal claims may be supported by strong evidence of a biological process with mechanistic evidence, such claims are not common in United States tort litigation.

In support of the claim that epidemiology is dispensable, Cranor suggests that:

“Some courts have recognized this, and distinguished scientific committees often do not require epidemiological studies to infer harm to humans. For example, the International Agency for Research on Cancer (IRAC) [sic], the National Toxicology Program, and California’s Proposition 65 Scientific Advisory Panel, among others, do not require epidemiological data to support findings that a substance is a probable or—in some cases—a known human carcinogen, but it is welcomed if available.”

Cranor at 149. California’s Proposition 65!??? Even IARC is hard to take seriously these days with its capture by consultants for the litigation industry, but if we were to accept IARC as an honest broker of causal inferences, what substance “known” to IARC to cause cancer in humans (Category I) was branded as a “known carcinogen” without the support of epidemiologic studies? Inquiring minds might want to know, but they will not learn the answer from Cranor and his co-authors.

When it comes to adverting to legal decisions that supposedly support the authors’ claim that epidemiology is unnecessary, their scholarship is equally wanting. The paper cites the notorious Wells case, which was so roundly condemned in scientific circles, that it probably helped ensure that a decision such as Daubert would ultimately be handed down by the Supreme Court. The authors seemingly cannot read, understand, and interpret even the most straightforward legal decisions. Here is how they cite Wells as support for their views:

“Wells v. Ortho Pharm. Corp., 788 F.2d 741, 745 (11th Cir. 1986) (reviewing a district court’s decision deciding not to require the use of epidemiological evidence and instead allowing expert testimony).”

Cranor at 149-50 n.122. The trial judge in Wells never made such a decision; indeed, the case was tried by the bench, before the Supreme Court decided Daubert. There was no gatekeeping involved at all. More important, however, and contrary to Cranor’s explanatory parenthetical, both sides presented epidemiologic evidence in support of their positions.12

Cranor and his co-authors similarly misread and misrepresent the trial court’s decision in the litigation over maternal sertraline use and infant birth defects. Twice they cite the Multi-District Litigation trial court’s decision that excluded plaintiffs’ expert witnesses:

“In re Zoloft (Sertraline Hydrochloride) Prods. Liab. Litig., 26 F. Supp. 3d 449, 455 (E.D. Pa. 2014) (expert may not rely on nonstatistically significant studies to which to apply the [Bradford Hill] factors).”

Cranor at 144 n.85; 158 n.179. The MDL judge, Judge Rufe, decidedly never held that an expert witness may not rely upon a statistically non-significant study in a “Bradford Hill” analysis, and the Third Circuit, which affirmed the exclusions of the plaintiffs’ expert witnesses’ testimony, was equally clear in avoiding the making of such a pronouncement.13

Who Needs Statistical Significance

Part of Cranor’s post-science agenda is to intimidate judges into believing that statistical significance is unnecessary and a wrong-headed criterion for judging the validity of relied upon research. In their article, Cranor and friends suggest that Hill agreed with their radical approach, but nothing could be further from the truth. Although these authors parse almost every word of Hill’s 1965 article, they conveniently omit Hill’s views about the necessary predicates for applying his nine considerations for causal inference:

“Disregarding then any such problem in semantics we have this situation. Our observations reveal an association between two variables, perfectly clear-cut and beyond what we would care to attribute to the play of chance. What aspects of that association should we especially consider before deciding that the most likely interpretation of it is causation?”

Austin Bradford Hill, “The Environment and Disease: Association or Causation?” 58 Proc. Royal Soc’y Med. 295, 295 (1965). Cranor’s radicalism leaves no room for assessing whether a putative association is “beyond what we would care to attribute to the play of chance,” and his poor scholarship ignores Hill’s insistence that this statistical analysis be carried out.14

Hill’s work certainly acknowledged the limitations of statistical method, which could not compensate for poorly designed research:

“It is a serious mistake to rely upon the statistical method to eliminate disturbing factors at the completion of the work.  No statistical method can compensate for a badly planned experiment.”

Austin Bradford Hill, Principles of Medical Statistics at 4 (4th ed. 1948). Hill was equally clear, however, that the limits on statistical methods did not imply that statistical methods are not needed to interpret a properly planned experiment or study. In the summary section of his textbook’s first chapter, Hill removed any doubt about his view of the importance, and the necessity, of statistical methods:

“The statistical method is required in the interpretation of figures which are at the mercy of numerous influences, and its object is to determine whether individual influences can be isolated and their effects measured.”

Id. at 10 (emphasis added).

In his efforts to eliminate judicial gatekeeping of expert witness testimony, Cranor has struggled with understanding of statistical inference and testing.15 In an early writing, a 1993 book, Cranor suggests that we “can think of type I and II error rates as “standards of proof,” which begs the question whether they are appropriately used to assess significance or posterior probabilities.16 Indeed, Cranor goes further, in confusing significance and posterior probabilities, when he described the usual level of alpha (5%) as the “95%” rule, and claimed that regulatory agencies require something akin to proof “beyond a reasonable doubt,” when they require two “statistically significant” studies.17

Cranor has persisted in this fallacious analysis in his writings. In a 2006 book, he erroneously equated the 95% coefficient of statistical confidence with 95% certainty of knowledge.18 Later in this same text, Cranor again asserted his nonsense that agency regulations are written when supported by “beyond a reasonable doubt.”19 Given that Cranor has consistently confused significance and posterior probability, he really should not be giving advice to anyone about statistical or scientific inference. Cranor’s persistent misunderstandings of basic statistical concepts do, however, explain his motivation for advocating the elimination of statistical significance testing, even if these misunderstandings make his enterprise intellectually unacceptable.

Cranor and company fall into a similar muddle when they offer advice on post-hoc power calculations, which advice ignores standard statistical learning for interpreting completed studies.20 Another measure of the authors’ failed scholarship is their omission of any discussion of recent efforts by many in the scientific community to lower the threshold for statistical significance, based upon the belief that the customary 5% p-value is an order of magnitude too high.21

 

Relative Risks Greater Than Two

There are other tendentious arguments and treatments in Cranor’s brief against gatekeeping, but I will stop with one last example. The inference of specific causation from study risk ratios has provoked a torrent of verbiage from Sander Greenland (who is cited copiously by Cranor). Cranor, however, does not even scratch the surface of the issue and fails to cite the work of epidemiologists, such as Duncan C. Thomas, who have defended the use of probabilities of (specific) causation. More important, however, Cranor fails to speak out against the abuse of using any relative risk greater than 1.0 to support an inference of specific causation, when the nature of the causal relationship is neither necessary nor sufficient. In this context, Kenneth Rothman has reminded us that someone can be exposed to, or have, a risk, and then develop the related outcome, without there being any specific causation:

“An elementary but essential principle to keep in mind is that a person may be exposed to an agent and then develop disease without there being any causal connection between the exposure and the disease. For this reason, we cannot consider the incidence proportion or the incidence rate among exposed people to measure a causal effect.”

Kenneth J. Rothman, Epidemiology: An Introduction at 57 (2d ed. 2012).

The danger in Cranor’s article in Jurimetrics is that some readers will not realize the extreme partisanship in its ipse dixit, and erroneous, pronouncements. Caveat lector!

Ninth Circuit’s Difficulty with Process of Elimination

September 16th, 2018

Differential etiology is a high-fallutin’ term given to a simple disjunctive syllogism in which all disjuncts in the premise but one are eliminated. The syllogism would be a persuasive argument for the one remaining disjunct but only if all the other premises are effectively eliminated. Otherwise, we are left with competing disjunctive premises that remain, without any way of embracing the “one,” for which someone is contending.

Over 100 years ago, the United States Supreme Court recognized the need for eliminating all but the claimed cause in a simple FELA negligence action. In a unanimous decision, the Court declared:

“And where the testimony leaves the matter uncertain and shows that any one of half a dozen things may have brought about the injury, for some of which the employer is responsible and for some of which he is not, it is not for the jury to guess between these half a dozen causes and find that the negligence of the employer was the real cause, when there is no satisfactory foundation in the testimony for that conclusion. If the employe is unable to adduce sufficient evidence to show negligence on the part of the employer, it is only one of the many cases in which the plaintiff fails in his testimony, and no mere sympathy for the unfortunate victim of an accident justifies any departure from settled rules of proof resting upon all plaintiffs.”

Patton v. Texas & Pacific RR, 179 U.S. 658, 663-64 (1901).

Recently the United States Court of Appeals, for the Ninth Circuit, recognized the need to rule out alternative factual explanations before a court could enter judgment on a claim of copyright infringement.1 Cobbler Nevada, LLC v Thomas Gonzales, No. 17-35041 (9th Cir., Aug. 27, 2018). The facts of Cobbler Nevada are illustrative.

Someone with access to an IP address registered to Thomas Gonzales used BitTorrent to download a copy of “The Cobbler,” an Adam Sandler movie. Cobbler Nevada LLC sued Mr. Gonzales, not for bad taste, but for infringing on its copyright to the movie. Mr. Gonzales, however, was the owner of an adult foster home, in which several other people had access to Gonzales’ IP address. Cobbler Nevada had no evidence that eliminated the possibility of downloading by other people in the home.

An amended complaint accused Mr. Gonzales of directly infringing the copyright, and alternatively, of contributing to the infringement by not policing this own internet connection.

The panel affirmed the rejection of the infringement claim because the claimant had failed to rule out downloading by someone who other Gonzales:

“The direct infringement claim fails because Gonzales’ status as the registered subscriber of an infringing IP address, standing alone, does not create a reasonable inference that he is also the infringer… .”

Id. The panel reasoned that others in the household could have accessed Gonzales’ internet connection, and that the law did not impose a duty to secure the connection from a “frugal” neighbor.

In personal injury cases, the Ninth Circuit takes a very different, and thoroughly illogical approach from its astute reasoning in Cobbler Nevada. In one Ninth Circuit case, the plaintiff claimed without much of any supporting evidence that he had sustained a drug-induced disease, when over 70 percent of cases of that disease were idiopathic. The trial court accurately diagnosed the situation as an impossible proof problem for the plaintiff because the differential etiology method could not eliminate idiopathic causes in the case before the court. Rule 702 led to the exclusion of plantiffs’ proffered opinions, and the trial court entered summary judgment for the defendants. The Ninth Circuit reversed in an ipse dixit judgment that threw logic to the wind. Wendell v. Johnson & Johnson, No. 09-cv-04124, 2014 WL 2943572, at *5 (N.D. Cal. June 30, 2014), rev’d sub nom. Wendell v. GlaxoSmithKline LLC, 858 F.3d 1227 (9th Cir. 2017).2

The two cases, Wendell and Cobbler Nevada, cannot be reconciled. The aberrant and costive reasoning of Wendell will give rise to unflattering speculation about the Circuit’s motivation. Perhaps the next edition of the Reference Manual on Scientific Evidence should have a chapter on elementary logic, to help avoid such embarrassing situations.

The Expert Witness Who Put God on His Reference List

August 28th, 2018

“And you never ask questions
When God’s on your side”

                                Bob Dylan, “With God on Our Side” 1963.

Cases involving claims of personal injury have inspired some of the most dubious scientific studies in the so-called medical literature, but the flights of fancy in published papers are nothing compared with what is recorded in the annals of expert witness testimony. The weaker the medical claims, the more outlandish is the expert testimony proffered. Claims for personal injury supposedly resulting from mold exposure are no exception to the general rule. The expert witness opinion testimony in mold litigation has resulted in several commentaries1 and professional position papers,2 offered to curb the apparent excesses.

Ritchie Shoemaker, M.D., has been a regular expert witness for the mold lawsuit industry. Professional criticism has not deterred Shoemaker, although discerning courts have put the kibosh on some of Shoemaker’s testimonial adventures.3

Shoemaker cannot be everywhere, and so in conjunction with the mold lawsuit industry, Shoemaker has taken to certifying new expert witnesses. But how will Shoemaker and his protégées overcome the critical judicial reception?

Enter Divine Intervention

“Make thee an ark of gopher wood; rooms shalt thou make in the ark, and shalt pitch it within and without with pitch.4”

Some say the age of prophets, burning bushes, and the like is over, but perhaps not so. Maybe God speaks to expert witnesses to fill in the voids left by missing evidence. Consider the testimony of Dr. Scott W. McMahon, who recently testified that he was Shoemaker trained, and divinely inspired:

Q. Jumping around a little bit, Doctor, how did your interest in indoor environmental quality in general, and mold in particular, how did that come about?

A. I had — in 2009, I had been asked to give a talk at a medical society at the end of October and the people who were involved in it were harassing me almost on a weekly basis asking me what the title of my talk was going to be. I had spoken to the same society the previous four years. I had no idea what I was going to speak about. I am a man of faith, I’ve been a pastor and a missionary and other things, so I prayed about it and what I heard in my head verbatim was pediatric mold exposure colon the next great epidemic question mark. That’s what I heard in my head. And so because I try to live by faith, I typed that up as an email and said this is the name of my topic. And then I said, okay, God, you have ten weeks to teach me about this, and he did. Within three, four weeks maybe five, he had connected me to Dr. Shoemaker who was the leading person in the world at that time and the discoverer of this chronic inflammatory response.

*****

I am a man of faith, I’ve been a pastor and everything. And I realized that this was a real entity.

*****

Q. And do you attribute your decision or the decision for you to start Whole World Health Care also to be a divine intervention?

A. Well, that certainly started the process but I used my brain, too. Like I said, I went and I investigated Dr. Shoemaker, I wanted to make sure that his methods were real, that he wasn’t doing, you know, some sort of voodoo medicine and I saw that he wasn’t, that his scientific practice was standard. I mean, he changes one variable at a time in tests. He tested every step of the way. And I found that his conclusions were realistic. And then, you know, over the last few years, I’ve 1 gathered my own data and I see that they confirm almost every one of his conclusions.

Q. Doctor, was there anything in your past or anything dealing with your family in terms of exposure to mold or other indoor health issues?

A. No, it was totally off my radar.

Q. *** I’m not going to go into great detail with respect to Dr. Shoemaker, but are you Shoemaker certified?

A. I am.

Deposition transcript of Dr. Scott W. McMahon, at pp.46-49, in Courcelle v. C.W. Nola Properties LLC, Orleans Parish, Louisiana No. 15-3870, Sec. 7, Div. F. (May 18, 2018).

You may be surprised that the examining lawyer did not ask about the voice in which God spoke. The examining lawyer seems to have accepted without further question that the voice was that of an adult male voice. Still did the God entity speak in English, or in tongues? Was it a deep, resonant voice like Morgan Freeman’s in Bruce Almighty (2003)? Or was it a Yiddische voice like George Burns, in Oh God (1977)? Were there bushes burning when God spoke to McMahon? Or did the toast burn darker than expected?

Some might think that McMahon was impudent if not outright blasphemous for telling God that “He” had 10 weeks in which to instruct McMahon in the nuances of how mold causes human illness. Apparently, God was not bothered by this presumptuousness and complied with McMahon, which makes McMahon a special sort of prophet.

Of course, McMahon says he used his “brain,” in addition to following God’s instructions. But really why bother? Were there evidentiary or inferential gaps filled in by the Lord? The deposition does not address this issue.

In federal court, and in many state courts, an expert witness may base opinions on facts or data that are not admissible if, and only if, expert witnesses “in the particular field would reasonably rely on those kinds of facts or data in forming an opinion on the subject.5”

Have other expert witnesses claimed divine inspiration for opinion testimony? A quick Pubmed search does not reveal any papers by God, or papers with God as someone’s Co-Author. It is only a matter of time, however, before a judge, some where, takes judicial notice of divinely inspired expert witness testimony.

The Appeal of the Learned Treatise

August 16th, 2018

In many states, the so-called “learned treatise” doctrine creates a pseudo-exception to the rule against hearsay. The contents of such a treatise can be read to the jury, not for its truth, but for the jury to consider against the credibility of an expert witness who denies the truth of the treatise. Supposedly, some lawyers can understand the distinction between the treatise’s content’s being admitted for its truth as opposed to the credibility of an expert witness who denies its truth. Under the Federal Rules of Evidence, and in some states, the language of the treatise may be considered for its truth as well, but the physical treatise may not be entered into evidence. There are several serious problems with both the state and the federal versions of the doctrine.1

Legal on-line media recently reported about an appeal in the Pennsylvania Superior Court, which heard arguments in a case that apparently turned on allegations of trial court error in refusing to allow learned treatise cross-examination of a plaintiff’s expert witness in Pledger v. Janssen Pharms., Inc., Phila. Cty. Ct. C.P., April Term 2012, No. 1997. See Matt Fair, “J&J Urges Pa. Appeals Court To Undo $2.5M Risperdal Verdict,” Law360 (Aug. 8, 2018) (reporting on defendants’ appeal in Pledger, Pa. Super. Ct. nos. 2088 EDA 2016 and 2187 EDA 2016).

In Pledger, plaintiff claimed that he developed gynecomastia after taking the defendants’ antipsychotic medication Risperdal. Defendants warned about gynecomastia, but the plaintiff claimed that the defendants had not accurately quantified the rate of gynecomastia in its package insert.

From Mr. Fair’s reporting, readers can discern only one ground for appeal, namely whether the “trial judge improperly barred it from using a scientific article to challenge an expert’s opinion that the antipsychotic drug Risperdal caused an adolescent boy to grow breasts.” Without having heard the full oral argument, or having read the briefs, the reader cannot tell whether there were other grounds. According to Mr. Fair, defense counsel contended that the trial court’s refusal to allow the learned treatise “had allowed the [plaintiff’s] expert’s opinion to go uncountered during cross-examination.” The argument, according to Mr. Fair, continued:

“Instead of being able to confront the medical causation expert with an article that absolutely contradicted and undermined his opinion, the court instead admonished counsel in front of the jury and said, ‘In Pennsylvania, we don’t try cases by books, we try them by live witnesses’.”

The cross-examination at issue, on the other hand, related to whether gynecomastia could occur naturally in pre-pubertal boys. Plaintiffs’ expert witness, Dr. Mark Solomon, a plastic surgeon, opined that gynecomastia did not occur naturally, and the defense counsel attempted to confront him with a “learned treatise,” an article from the Journal of Endocrinology, which apparently stated to the contrary. Solomon, following the usual expert witness playbook, testified that he had not read the article (and why would a surgeon have read this endocrinology journal?) Defense counsel pressed, and according to Mr. Fair, the trial judge disallowed further inquiry on cross-examination. On appeal, the defendants argued that the trial judge violated the learned treatise rule that allows “scholarly articles to be used as evidence.” The plaintiffs contended, in defense of their judgment below, that the “learned treatise rule” does not allow “scholarly articles to simply be read verbatim into the record,” and that the defense had the chance to raise the article in the direct examination of its own expert witnesses.

The Law360 reporting is curious on several fronts. The assigned error would have only been in support of a challenge to the denial of a new trial, and in a Risperdal case, the defense would likely have made a motion for judgment notwithstanding the verdict, as well as for new trial. Although the appellate briefs are not posted online, the defense’s post-trial motions in Pledger v. Janssen Pharms., Inc., Phila. Cty. Ct. C.P., April Term 2012, No. 1997, are available. See Defendants’ Motions for Post-Trial Relief Pursuant to Pa.R.C.P. 227.1 (Mar. 6, 2015).

At least at the post-trial motion stage, the defendants clearly made both motions for judgment and for a new trial, as expected.

As for the preservation of the “learned treatise” issue, the entire assignment of error is described in a single paragraph (out of 116 paragraphs) in the post-trial motion, as follows:

27. Moreover, appearing to rely on Aldridge v. Edmunds, 750 A.2d 292 (Pa. 2000), the Court prevented Janssen from cross-examining Dr. Solomon with scientific authority that would undermine his position. See, e.g., Tr. 60:9-63:2 (p.m.). Aldridge, however, addresses the use of learned treatises in the direct examination, and it cites with approval the case of Cummings v. Borough of Nazareth, 242 A.2d 460, 466 (Pa. 1968) (plurality op.), which stated that “[i]t is entirely proper in examination and cross-examination for counsel to call the witness’s attention to published works on the matter which is the subject of the witness’s testimony.” Janssen should not have been so limited in its cross examination of Dr. Solomon.

In Cummings, the issue revolved around using manuals that contained industry standards for swimming pool construction, not the appropriateness of a learned scientific treatise. Cummings v. Nazareth Borough, 430 Pa. 255, 266-67 (Pa. 1968). The defense motion did not contend that the defense counsel had laid the appropriate foundation for the learned treatise to be used. In any event, the trial judge wrote an opinion on the post-trial motions, in which he did not appear to address the learned treatise issue at all. Pledger v Janssen Pharms, Inc., Phila. Ct. C.P., Op. sur post-trial motions (Aug. 10., 2017) (Djerassi, J.).

The Pennsylvania Supreme Court has addressed the learned treatise exception to the rule against hearsay on several occasions. Perhaps the leading case described the law as:

“well-settled that an expert witness may be cross-examined on the contents of a publication upon which he or she has relied in forming an opinion, and also with respect to any other publication which the expert acknowledges to be a standard work in the field. * * * In such cases, the publication or literature is not admitted for the truth of the matter asserted, but only to challenge the credibility of the witness’ opinion and the weight to be accorded thereto. * * * Learned writings which are offered to prove the truth of the matters therein are hearsay and may not properly be admitted into evidence for consideration by the jury.”

Majdic v. Cincinnati Mach. Co., 537 A. 2d 334, 621-22 (Pa. 1988) (internal citations omitted).

The Law360 report is difficult to assess. Perhaps the reporting by Mr. Fair was non-eponymously unfair? There is no discussion of how the defense had laid its foundation. Perhaps the defense had promised “to connect up” by establishing the foundation of the treatise through a defense expert witness. If there had been a foundation established, or promised to be established, the post-trial motion would have, in the normal course of events, cited the transcript for the proffer of a foundation. And why did Mr. Fair report on the oral argument as though the learned treatise issue was the only issue before the court? Inquiring minds want to know.

Judge Djerassi’s opinion on post-trial motions was perhaps more notable for embracing some testimony on statistical significance from Dr. David Kessler, former Commissioner of the FDA, and now a frequent testifier for the lawsuit industry on regulatory matters. Judge Djerassi, in his opinion, stated:

“This statistically significant measure is shown in Table 21 and was within a chi-square rate of .02, meaning within a 98% chance of certainty. In Dr. Kessler’s opinion this is a statistically significant finding. (N.T. 1/29/15, afternoon, pp. p. 27, ln. 2 10-11, p. 28, lns. 7-12).”

Post-trial opinion at p.11.2 Surely, the defense’s expert witnesses explained that the chi-square test did not yield a measure of certainty that the measured statistic was the correct value.

The trial court’s whopper was enough of a teaser to force me to track down Kessler’s testimony, which was posted to the internet by the plaintiffs’ law firm. Judge Djerassi’s erroneous interpretation of the p-value can indeed be traced to Kessler’s improvident testimony:

Q. And since 2003, what have you been doing at University of California San Francisco, sir?

A. Among other things, I am currently a professor of pediatrics, professor of epidemiology, professor of biostatistics.

Pledger Transcript, Thurs., Jan. 28, 2015, Vol. 3, Morning Session at 111:3-7.

A. What statistical significance means is it’s mathematical and scientific calculations, but when we say something is statistically significant, it’s unlikely to happen by chance. So that association is very likely to be real. If you redid this, general statistically significant says if I redid this and redid the analysis a hundred times, I would get the same result 95 of those times.

Pledger Transcript, Fri., Jan. 29, 2015, Vol. 4, Morning Session at 80:18 – 81:2.

Q. So, sir, if we see on a study — and by the way, do the investigators of a study decided in their own criteria what is statistically significant? Do they assign what’s called a P value?

A. Exactly. So you can set it at 95, you can set it at 98, you can set it at 90. Generally, 95 significance level, for those of you who are mathematicians or scientifically inclined, it’s a P less than .05.

Q. As a general rule?

A. Yes.

Q. So if I see a number that is .0158, next to a dataset, that would mean that it occurs by chance less than two in 100. Correct?

A. Yes, that’s what the P value is saying.

Pledger Transcript, Fri., Jan. 29, 2015, Vol. 4, Morning Session at 81:5-20

Q. … If someone — if something has a p-value of less than .02, the converse of it is that your 98 — .98, that would be 98 percent certain that the result is not by chance?

A. Yes. That’s a fair way of saying it.

Q. And if you have a p-value of .10, that means the converse of it is 90 percent, or 90 percent that it’s not by chance, correct?

A. Yes.

Pledger Transcript, Fri., Jan. 29, 2015, Vol. 4, Afternoon Session at 7:14-22.

Q. Okay. And the last thing I’d like to ask about — sorry to keep going back and forth — is so if the jury saw a .0158, that’s of course less than .02, which means that it is 90 — almost 99 percent not by chance.

A. Yes. It’s statistically significant, as I would call it.

Pledger Transcript, Fri., Jan. 29, 2015, Vol. 4, Afternoon Session at 8:7-13.

Tremolitic Tergiversation or Ex-PIRG-Gation?

August 11th, 2018

My first encounter with the Public Interest Research Group (PIRG) was as an undergraduate when my college mandated that part of the student activity fee went to New Jersey PIRG. The college administration gave students no choice in the matter.

Upon investigating PIRG’s activities and rhetoric, I found the organization filled with self-aggrandizement, and puffed out with a self-satisfied arrogance. Epistemically, politically, and historically, an organization that declared all its goals to be “in the public interest” was jarring and objectionable, but it was probably just my own idiosyncratic sensitivity.

Many of my fellow students and I protested the forced support for PIRG, and ultimately the college yielded to the tide of opinion. Students were give a choice to opt out of paying the portion of their fees that went to PIRG.

Almost 50 years later, I still have a healthy skepticism of most self-proclaimed “public interest” groups, including PIRG. And so, my antennae went up upon seeing a New York Times article about a PIRG back-to-school shopping guide, with warnings about hazardous materials in crayons and magic markers. See Niraj Chokshi, “Asbestos in a Crayon, Benzene in a Marker: A School Supply Study’s Toxic Results,” N.Y. Times (Aug. 8, 2018). The hazard lurking in crayons, according to PIRG, was none other than the emperor of all toxic substances: asbestos. The Times dutifully reported that PIRG had found only “trace” tremolite, but the newspaper made no attempt to quantify the amount found; nor did the paper describe the meaninfulness of inhalational exposure from trace amount of tremolite embedded in wax. Instead, the Times reported a worrisome quote: “Tremolite is responsible for many cases of asbestos-related cancer and asbestos diseases, according to the Abramson Cancer Center at the University of Pennsylvania.”

* * * * * * * * * * *

“A thing is a phallic symbol if it is longer than it is wide.” 

Melanie, Safka (1972)

“A thing is a fiber if it is three times longer than it is wide.” 

O.S.H.A., 29 C.F.R. § 1910.1001(b) (defining fiber as having a length-to- diameter ratio of at least 3 to 1).

Ergo, all fibers are phallic symbols.

* * * * * * * * * * *

The New York Times article did link to PIRG’s report, which at least allowed readers to inspect the inculpatory evidence. U.S. PIRG, Safer School Supplies: Shopping Guide: Consumer Guide for Finding Non-Toxic School Supplies (2018). Unfortunately, the PIRG report did not answer crucial questions. There was no quantification of the tremolite asbestos, and there was no discussion of the ability of the tremolite to escape the wax matrix of the crayon, to become airborne, and to be inhaled. The report did cite the methodology used to ascertain the presence of the tremolite (EPA Method: EPA/600/R-93/116). Safer Schools at 5. In Appendix A to the report, the authors showed two microphotographs of tremolite particles, but without any measurement scale. One of the two tremolite particles looks like a cleavage fragment, not a fiber. The other photomicrograph shows something that might be a fiber, but without a scale and a report of the elemental peaks, the reader cannot tell for sure. Safer Schools at 21.

The controversy over the potential health effects of tremolite cleavage fragments has a long history. Compare Robert Reger & W. Keith C. Morgan, “On talc, tremolite, and tergiversation,” 47 Brit. J. Indus. Med. 505 (1990) with Bruce W. Case, “On talc, tremolite, and tergiversation. Ter-gi-ver-sate: 2: to use subterfuges,” 48 Brit. J. Indus. Med. 357 (1991). The regulatory definition of fiber does not distinguish between biologically significant fibers and particles with an aspect ratio greater than three. John Gamble & Graham Gibbs, “An evaluation of the risks of lung cancer and mesothelioma from exposure to amphibole cleavage fragments,” 52 Regulatory Toxicol. & Pharmacol. S154 (2008) (the weight of evidence fully supports a conclusion that non-asbestiform amphiboles do not increase the risk of lung cancer or mesothelioma); Brent L. Finley, Stacey M. Benson & Gary M. Marsh, “Cosmetic talc as a risk factor for pleural mesothelioma: a weight of evidence evaluation of the epidemiology,” 29 Inhalation Toxicol. 179 (2017).

Surely the public interest includes the facts and issues left out by PIRG’s report.

N.J. Supreme Court Uproots Weeds in Garden State’s Law of Expert Witnesses

August 8th, 2018

The United States Supreme Court’s decision in Daubert is now over 25 years old. The idea of judicial gatekeeping of expert witness opinion testimony is even older in New Jersey state courts. The New Jersey Supreme Court articulated a reliability standard before the Daubert case was even argued in Washington, D.C. See Landrigan v. Celotex Corp., 127 N.J. 404, 414 (1992); Rubanick v. Witco Chem. Corp., 125 N.J. 421, 447 (1991). Articulating a standard, however, is something very different from following a standard, and in many New Jersey trial courts, until very recently, the standard was pretty much anything goes.

One counter-example to the general rule of dog-eat-dog in New Jersey was Judge Nelson Johnson’s careful review and analysis of the proffered causation opinions in cases in which plaintiffs claimed that their use of the anti-acne medication isotretinoin (Accutane) caused Crohn’s disease. Judge Johnson, who sits in the Law Division of the New Jersey Superior Court for Atlantic County held a lengthy hearing, and reviewed the expert witnesses’ reliance materials.1 Judge Johnson found that the plaintiffs’ expert witnesses had employed undue selectivity in choosing what to rely upon. Perhaps even more concerning, Judge Johnson found that these witnesses had refused to rely upon reasonably well-conducted epidemiologic studies, while embracing unpublished, incomplete, and poorly conducted studies and anecdotal evidence. In re Accutane, No. 271(MCL), 2015 WL 753674, 2015 BL 59277 (N.J.Super. Law Div., Atlantic Cty. Feb. 20, 2015). In response, Judge Johnson politely but firmly closed the gate to conclusion-driven duplicitous expert witness causation opinions in over 2,000 personal injury cases. “Johnson of Accutane – Keeping the Gate in the Garden State” (Mar. 28, 2015).

Aside from resolving over 2,000 pending cases, Judge Johnson’s judgment was of intense interest to all who are involved in pharmaceutical and other products liability litigation. Judge Johnson had conducted a pretrial hearing, sometimes called a Kemp hearing in New Jersey, after the New Jersey Supreme Court’s opinion in Kemp v. The State of New Jersey, 174 N.J. 412 (2002). At the hearing and in his opinion that excluded plaintiffs’ expert witnesses’ causation opinions, Judge Johnson demonstrated a remarkable aptitude for analyzing data and inferences in the gatekeeping process.

When the courtroom din quieted, the trial court ruled that the proffered testimony of Dr., Arthur Kornbluth and Dr. David Madigan did not meet the liberal New Jersey test for admissibility. In re Accutane, No. 271(MCL), 2015 WL 753674, 2015 BL 59277 (N.J.Super. Law Div. Atlantic Cty. Feb. 20, 2015). And in closing the gate, Judge Johnson protected the judicial process from several bogus and misleading “lines of evidence,” which have become standard ploys to mislead juries in courthouses where the gatekeepers are asleep. Recognizing that not all evidence is on the same analytical plane, Judge Johnson gave case reports short shrift.

“[u]nsystematic clinical observations or case reports and adverse event reports are at the bottom of the evidence hierarchy.”

Id. at *16. Adverse event reports, largely driven by the very litigation in his courtroom, received little credit and were labeled as “not evidentiary in a court of law.” Id. at 14 (quoting FDA’s description of FAERS).

Judge Johnson recognized that there was a wide range of identified “risk factors” for irritable bowel syndrome, such as prior appendectomy, breast-feeding as an infant, stress, Vitamin D deficiency, tobacco or alcohol use, refined sugars, dietary animal fat, fast food. In re Accutane, 2015 WL 753674, at *9. The court also noted that there were four medications generally acknowledged to be potential risk factors for inflammatory bowel disease: aspirin, nonsteroidal anti-inflammatory medications (NSAIDs), oral contraceptives, and antibiotics. Understandably, Judge Johnson was concerned that the plaintiffs’ expert witnesses preferred studies unadjusted for potential confounding co-variables and studies that had involved “cherry picking the subjects.” Id. at *18.

Judge Johnson had found that both sides in the isotretinoin cases conceded the relative unimportance of animal studies, but the plaintiffs’ expert witnesses nonetheless invoked the animal studies in the face of the artificial absence of epidemiologic studies that had been created by their cherry-picking strategies. Id.

Plaintiffs’ expert witnesses had reprised a common claimants’ strategy; namely, they claimed that all the epidemiology studies lacked statistical power. Their arguments often ignored that statistical power calculations depend upon statistical significance, a concept to which many plaintiffs’ counsel have virulent antibodies, as well as an arbitrarily selected alternative hypothesis of association size. Furthermore, the plaintiffs’ arguments ignored the actual point estimates, most of which were favorable to the defense, and the observed confidence intervals, most of which were reasonably narrow.

The defense responded to the bogus statistical arguments by presenting an extremely capable clinical and statistical expert witness, Dr. Stephen Goodman, to present a meta-analysis of the available epidemiologic evidence.

Meta-analysis has become an important facet of pharmaceutical and other products liability litigation[1]. Fortunately for Judge Johnson, he had before him an extremely capable expert witness, Dr. Stephen Goodman, to explain meta-analysis generally, and two meta-analyses he had performed on isotretinoin and irritable bowel outcomes.

Dr. Goodman explained that the plaintiffs’ witnesses’ failure to perform a meta-analysis was telling when meta-analysis can obviate the plaintiffs’ hyperbolic statistical complaints:

“the strength of the meta-analysis is that no one feature, no one study, is determinant. You don’t throw out evidence except when you absolutely have to.”

In re Accutane, 2015 WL 753674, at *8.

Judge Johnson’s judicial handiwork received non-deferential appellate review from a three-judge panel of the Appellate Division, which reversed the exclusion of Kornbluth and Madigan. In re Accutane Litig., 451 N.J. Super. 153, 165 A.3d 832 (App. Div. 2017). The New Jersey Supreme Court granted the isotretinoin defendants’ petition for appellate review, and the issues were joined over the appropriate standard of appellate review for expert witness opinion exclusions, and the appropriateness of Judge Johnson’s exclusions of Kornbluth and Madigan. A bevy of amici curiae joined in the fray.2

Last week, the New Jersey Supreme Court issued a unanimous opinion, which reversed the Appellate Division’s holding that Judge Johnson had “mistakenly exercised” discretion. Applying its own precedents from Rubanick, Landrigan, and Kemp, and the established abuse-of-discretion standard, the Court concluded that the trial court’s ruling to exclude Kornbluth and Madigan was “unassailable.” In re Accutane Litig., ___ N.J. ___, 2018 WL 3636867 (2018), Slip op. at 79.3

The high court graciously acknowledged that defendants and amici had “good reason” to seek clarification of New Jersey law. Slip op. at 67. In abandoning abuse-of-discretion as its standard of review, the Appellate Division had relied upon a criminal case that involved the application of the Frye standard, which is applied as a matter of law. Id. at 70-71. The high court also appeared to welcome the opportunity to grant review and reverse the intermediate court reinforce “the rigor expected of the trial court” in its gatekeeping role. Id. at 67. The Supreme Court, however, did not articulate a new standard; rather it demonstrated at length that Judge Johnson had appropriately applied the legal standards that had been previously announced in New Jersey Supreme Court cases.4

In attempting to defend the Appellate Division’s decision, plaintiffs sought to characterize New Jersey law as somehow different from, and more “liberal” than, the United States Supreme Court’s decision in Daubert. The New Jersey Supreme Court acknowledged that it had never formally adopted the dicta from Daubert about factors that could be considered in gatekeeping, slip op. at 10, but the Court went on to note what disinterested observers had long understood, that the so-called Daubert factors simply flowed from a requirement of sound methodology, and that there was “little distinction” and “not much light” between the Landrigan and Rubanick principles and the Daubert case or its progeny. Id at 10, 80.

Curiously, the New Jersey Supreme Court announced that the Daubert factors should be incorporated into the New Jersey Rules 702 and 703 and their case law, but it stopped short of declaring New Jersey a “Daubert” jurisdiction. Slip op. at 82. In part, the Court’s hesitance followed from New Jersey’s bifurcation of expert witness standards for civil and criminal cases, with the Frye standard still controlling in the criminal docket. At another level, it makes no sense to describe any jurisdiction as a “Daubert” state because the relevant aspects of the Daubert decision were dicta, and the Daubert decision and its progeny were superseded by the revision of the controlling statute in 2000.5

There were other remarkable aspects of the Supreme Court’s Accutane decision. For instance, the Court put its weight behind the common-sense and accurate interpretation of Sir Austin Bradford Hill’s famous articulation of factors for causal judgment, which requires that sampling error, bias, and confounding be eliminated before assessing whether the observed association is strong, consistent, plausible, and the like. Slip op. at 20 (citing the Reference Manual at 597-99), 78.

The Supreme Court relied extensively on the National Academies’ Reference Manual on Scientific Evidence.6 That reliance is certainly preferable to judicial speculations and fabulations of scientific method. The reliance is also positive, considering that the Court did not look only at the problematic epidemiology chapter, but adverted also to the chapters on statistical evidence and on clinical medicine.

The Supreme Court recognized that the Appellate Division had essentially sanctioned an anything goes abandonment of gatekeeping, an approach that has been all-too-common in some of New Jersey’s lower courts. Contrary to the previously prevailing New Jersey zeitgeist, the Court instructed that gatekeeping must be “rigorous” to “prevent[] the jury’s exposure to unsound science through the compelling voice of an expert.” Slip op. at 68-9.

Not all evidence is equal. “[C]ase reports are at the bottom of the evidence hierarchy.” Slip op. at 73. Extrapolation from non-human animal studies is fraught with external validity problems, and such studies “far less probative in the face of a substantial body of epidemiologic evidence.” Id. at 74 (internal quotations omitted).

Perhaps most chilling for the lawsuit industry will be the Supreme Court’s strident denunciation of expert witnesses’ selectivity in choosing lesser evidence in the face of a large body of epidemiologic evidence, id. at 77, and their unprincipled cherry picking among the extant epidemiologic publications. Like the trial court, the Supreme Court found that the plaintiffs’ expert witnesses’ inconsistent use of methodological criteria and their selective reliance upon studies (disregarding eight of the nine epidemiologic studies) that favored their task masters was the antithesis of sound methodology. Id. at 73, citing with approval, In re Lipitor, ___ F.3d ___ (4th Cir. 2018) (slip op. at 16) (“Result-driven analysis, or cherry-picking, undermines principles of the scientific method and is a quintessential example of applying methodologies (valid or otherwise) in an unreliable fashion.”).

An essential feature of the Supreme Court’s decision is that it was not willing to engage in the common reductionism that has “all epidemiologic studies are flawed,” and which thus privileges cherry picking. Not all disagreements between expert witnesses can be framed as differences in interpretation. In re Accutane will likely stand as a bulwark against flawed expert witness opinion testimony in the Garden State for a long time.

1 Judge Nelson Johnson is also the author of Boardwalk Empire: The Birth, High Times, and Corruption of Atlantic City (2010), a spell-binding historical novel about political and personal corruption.

2 In support of the defendants’ positions, amicus briefs were filed by the New Jersey Business & Industry Association, Commerce and Industry Association of New Jersey, and New Jersey Chamber of Commerce; by law professors Kenneth S. Broun, Daniel J. Capra, Joanne A. Epps, David L. Faigman, Laird Kirkpatrick, Michael M. Martin, Liesa Richter, and Stephen A. Saltzburg; by medical associations the American Medical Association, Medical Society of New Jersey, American Academy of Dermatology, Society for Investigative Dermatology, American Acne and Rosacea Society, and Dermatological Society of New Jersey, by the Defense Research Institute; by the Pharmaceutical Research and Manufacturers of America; and by New Jersey Civil Justice Institute. In support of the plaintiffs’ position and the intermediate appellate court’s determination, amicus briefs were filed by political action committee the New Jersey Association for Justice; by the Ironbound Community Corporation; and by plaintiffs’ lawyer Allan Kanner.

3 Nothing in the intervening scientific record called question upon Judge Johnson’s trial court judgment. See, e.g., I.A. Vallerand, R.T. Lewinson, M.S. Farris, C.D. Sibley, M.L. Ramien, A.G.M. Bulloch, and S.B. Patten, “Efficacy and adverse events of oral isotretinoin for acne: a systematic review,” 178 Brit. J. Dermatol. 76 (2018).

Corp., 125 N.J. 421, 447 (1991) (“We initially took that step to allow the parties in toxic tort civil matters to present novel scientific evidence of causation if, after the trial court engages in rigorous gatekeeping when reviewing for reliability, the proponent persuades the court of the soundness of the expert’s reasoning.”).

5 The Court did acknowledge that Federal Rule of Evidence 702 had been amended in 2000, to reflect the Supreme Court’s decision in Daubert, Joiner, and Kumho Tire, but the Court did not deal with the inconsistencies between the present rule and the 1993 Daubert case. Slip op. at 64, citing Calhoun v. Yamaha Motor Corp., U.S.A., 350 F.3d 316, 320-21, 320 n.8 (3d Cir. 2003).

6 See Accutane slip op. at 12-18, 24, 73-74, 77-78. With respect to meta-analysis, the Reference Manual’s epidemiology chapter is still stuck in the 1980s and the prevalent resistance to poorly conducted, often meaningless meta-analyses. See “The Treatment of Meta-Analysis in the Third Edition of the Reference Manual on Scientific Evidence” (Nov. 14, 2011) (The Reference Manual fails to come to grips with the prevalence and importance of meta-analysis in litigation, and fails to provide meaningful guidance to trial judges).

August 4th, 2018

Two Stanford University communications researchers have shown that fraudulent publications and authors’ linguistic obfuscation are correlated, p < 0.05. David M. Markowitz & Jeffrey T. Hancock, “Linguistic Obfuscation in Fraudulent Science,” 35 J. Language & Social Psych. 435 (2016); Bjorn Carey, “Stanford researchers uncover patterns in how scientists lie about their data,” Stanford Report (Nov. 16, 2015) [Carey, below]

Stanford Professor of Communication, Jeff Hancock, and graduate student David Markowitz observed that there are repeating patterns of expression in the language used by scientific fraudfeasors. They hypothesized that scientific fraudfeasors would signal their duplicity in their linguistic expressions as well. These authors created a linguistic obfuscation index based upon the prevalence of jargon, abstraction, positive emotion terms, and readability. They then compared the obfuscation index scores of 253 papers retracted for fraudulent data with 253 unretracted papers, and 63 papers retracted for reasons other than fraud. Not surprisingly, Hancock and Markowitz found differences, with fraudulent papers having higher obfuscation scores, and generally more jargon.

As Markowitz explained:

“We believe the underlying idea behind obfuscation is to muddle the truth. *** Scientists faking data know that they are committing a misconduct and do not want to get caught. Therefore, one strategy to evade this may be to obscure parts of the paper. We suggest that language can be one of many variables to differentiate between fraudulent and genuine science.”

Carey. Professor Hancock acknowledged that there remained a high error rate in their obfuscation analysis, which needed to be lowered before automatic linguistic analyses could be useful for detecting fraud. Hancock also acknowledged that such the use of such a computerized linguistic tool might undermine the trust upon which science is based. Id.

Well detecting fraud might undermine trust, but look where trust has gotten us in science.

Trust but verify.

I cannot wait until I proffer the first expert witness rebuttal report in litigation, to show that my adversary’s expert witness has crossed the obfuscation line.

From Here to CERT-ainty

June 28th, 2018

An enterprising journalist, Michael Waters, recently published an important exposé on the Council for Education and Research on Toxics (CERT). Michael Waters, “The Secretive Non-Profit Gaming California’s Health Laws: The Council for Education and Research on Toxics has won million-dollar settlements using a controversial public health law,” The Outline (June 18, 2018). Digging deep into the shadowy organization, Mr. Waters reported that:

“CERT doesn’t have a website, a social media account, or any notable public presence, despite having won million-dollar judgments by suing corporations. However, files from the California Secretary of State show that in May 30, 2001, four people co-founded the non-profit: C. Sterling Wolfe, a former environmental lawyer; Brad Lunn; Carl Cranor, a toxicology professor at University of California Riverside; and Martyn T. Smith, a toxicology professor at Berkeley.”

Id.

Mr. Water’s investigation puts important new facts on the table about the conduct of the CERT corporation. The involvement of Christopher Sterling Wolfe, a Torrance, California, plaintiffs’ lawyer, is not terribly surprising. The involvement in CERT of frequent plaintiffs’ expert witnesses, Carl F. Cranor and Martyn T. Smith, however, raises serious ethical questions. Both Cranor and Smith were expert witnesses for plaintiffs in the infamous Milward case,1 and after the trial court excluded their testimony and granted summary judgment, CERT filed an amicus brief in the Court of Appeals.2

The rules governing amicus briefs in federal appellate courts require disclosure of the amicus’s interest in the proceedings. By the time that CERT filed its amicus brief in Milward, Cranor and Smith may not have been officers of the corporation, but given CERT’s funding of Smith’s research, these “Founding Fathers” certainly had a continuing close relationship with the corporation.3 “Coffee with Cream, Sugar & a Dash of Acrylamide” (June 9, 2018). Given CERT’s name, which suggests a public interest mission, the corporation’s litigation activities on behalf of its founders, Cranor and Smith, exhibit a certain lack of candor with the court.

======================

My discussions with Mr. Waters, and his insightful piece in The Outline, led to a call from Madeleine Brand, who wanted to discuss CERT’s litigation against Starbucks, under California’s Proposition 65 laws, over acrylamide content in coffee. David Roe, a self-styled environmental activist and drafter of California’s bounty hunting law, was interviewed directly after me.4

As every California now no doubt knows, acrylamide is present in many foods. The substance is created when the amino acid asparagine is heated in the presence of sugars. Of course, I expected to hear Roe defend his creation, Proposition 65, generally, and the application of Proposition 65 to the low levels of acrylamide in coffee, perhaps on contrary-to-fact precautionary principle grounds. What surprised me were Roe’s blaming the victim, Starbucks for not settling, and his strident assertions that it was a long-established fact that acrylamide causes cancer.

Contrary to Roe’s asseverations, the National Cancer Institute has evaluated the acrylamide issues quite differently. On its website, the NCI has addressed “Acrylamide and Cancer Risk,” and mostly found none. Roe had outrageously suggested that there were no human data, because of the ethics of feeding acrylamide to humans, and so regulators had to rely upon rodent studies. The NCI, however, had looked at occupational studies in which workers were exposed to acrylamide in manufacturing processes at levels much higher than any dietary intake. The NCI observed “studies of occupational exposure have not suggested increased risks of cancer.” As for rodents, the NCI noted that “toxicology studies have shown that humans and rodents not only absorb acrylamide at different rates, they metabolize it differently as well.”

The NCI’s fact sheet is a relatively short précis, but the issue of acrylamide has been addressed in many studies, collected and summarized in meta-analyses.5 Since the NCI’s summary of the animal toxicology and human epidemiology, several important research groups have reported careful human studies that consistently have found no association between dietary acrylamide and cancer risk.6

Coffee with Cream, Sugar & a Dash of Acrylamide

June 9th, 2018

Causal statements are made all the time without much thought of their epistemic warrant. On a day that the stock market indices fall, would-be economic pundits point to some putative cause, such as concern about wage inflation. When the stock market rises on the following day, the explanation is that investors were buoyed by corporate tax cuts, even though those tax cuts were supposedly designed to help companies increase wages. As philosophy professor Harry Frankfurt has explained:

“Bullshit is unavoidable whenever circumstances require someone to talk without knowing what he is talking about. Thus the production of bullshit is stimulated whenever a person’s obligations or opportunities to speak about some topic exceed his knowledge of the facts that are relevant to that topic.”1

Of course, Frankfurt’s dictum aptly describes the situation with much of expert witness testimony in health effects litigation.

Nothing seems to stimulate speculative causal claiming as much as the potential rewards of rent-seeking litigation under Proposition 65. By popular referendum, the State of California has taken upon itself to make pronouncements about the causal effects of various foods, drugs, and exposures. The referendum became a California statute with the Safe Drinking Water and Toxic Enforcement Act of 1986. Proposition 65 and the subsequent Enforcement Act require the State of California to publish a list of chemicals it “knows” cause cancers or birth defects. California knows a lot. The list, updated annually, now includes about 800 chemicals.

When California knows that a chemical or an exposure causes cancer, the state does not necessarily know that the chemical or exposure causes cancer in human beings; nor does it necessarily know that the chemical or exposure causes cancer at the exposure level experienced by the citizens of the state. Furthermore, many exposures occur in the context of complex mixtures in which a hypothetical effect of one chemical might be offset or antagonized by another chemical in the mixture. But nonetheless, what California “knows” can hurt you if you are on the wrong side of a Prop 65 enforcement action.

What has California gotten for all its “knowledge”? Clearly, the Proposition 65 statute has created huge incentives for private citizens to sue for violations by creating private rights of action against businesses that supposedly violate the law by failing to warn about what California knows. The proof standards for “known to cause cancer” are so removed from scientific discourse that forcing monetary settlements out of California businesses has become at once a big business itself, and a twisted process that distorts the truth of health hazards and benefits. There have been occasional outcries about the abusive system created from what once was perhaps a well-intentioned reform,2 but for the most part, Prop 65 has become the abnormal normal in California.

Mostly California has gotten lawsuits and a glut of warnings with no difference in cancer or birth defect rates than those observed in states less knowledgeable on such matters.3 Some of California’s cancer rates may be a bit lower than the national rates but this outcome is largely the result of lower state rates for smoking and obesity. Some birth defect rates (neural tube defects) are actually higher in California than in the country as a whole.4

Last year, 681 Prop 65 settlements worth $25.6 million were reported to the California attorney general’s office. Attorneys’ and expert witness fees and other litigation costs made up more than 75% of the total.5 The rate of return has been steady over the years. In 2011, 74 percent of Proposition 65 awards went to attorneys’ fees and costs.6

Council for Education and Research on Toxics (CERT)

For all the hoopla over CERT’s lawsuit against Starbucks,7 there has been little coverage of the actual testimony from the trial. One journalist did report that Peter Infante, a frequent testifier for the lawsuit industry, testified on epidemiology for CERT’s lawyer, Raphael Metzger.8 Apparently, Infante described some studies as showing statistically significant correlations between coffee drinking and some kinds of cancer. Infante demurred on whether coffee caused these kinds of cancer, and admitted that one “would need a clinical trial to resolve the issue.” David Kessler, the former FDA commissioner who helped create the breast implant litigation fiasco and who now testifies frequently for the Lawsuit Industry, testified for Starbucks. Despite his substantial fear-mongering credentials, Dr Kessler emphasized that coffee is a “staple of the American diet,” and that drinking coffee has known health benefits. As everyone now knows, Starbucks failed to persuade the California trial judge that coffee, acrylamide and all, should come under the statute’s safe harbor provisions.

Almost five years ago, I first blogged about the CERT, in connection with the Milward case.9 When I first wrote back in 2013, and until the present, CERT, has not had a website, which is odd for an organization that professes to have an educational mission. In 2013, my research on CERT showed it to be a California corporation, EIN: 42-1571530, founded in 2003, with a business address at 401 E. Ocean Blvd., Ste. 800, Long Beach, California 90802-4967, and a telephone number:  1-877-TOX-TORT. CERT’s reported mission statement was furthering scientific understanding of toxins. Plaintiffs’ lawyer Ralph Metzger, a denizen of the Prop 65 world, was noted as the contact person for CERT, and indeed, the telephone number for CERT was the same as that for Metzger’s lawfirm, the Metzger Law Group.

As I started to watch the activities of CERT, I detected some curious patterns. I saw CERT file amicus briefs in legal cases, which is not the typical activity of a scientific research organization.10 Even more curious, and somewhat dubious, in two cases in which Ralphael Metzger of the Metzger Law Group represented the plaintiffs, another firm, Richard Alexander of the Alexander Law Group, represented CERT as an amicus in the same cases.11

Given the publicity created by CERT’s victory in its Proposition 65 citizen’s action against Starbucks, I recently revisited this research. See Alexander Nazaryan, “Will coffee in California come with a cancer warning?” Los Angeles Times (Feb. 18, 2018). One group, “Deniers for Hire,” which describes itself as committed to “debunk anti-science propaganda and expose the activists who produce it,” identified CERT as:

“a sham environmentalist nonprofit that sues food companies and collects settlements to fund additional lawsuits against other food companies. Founded in 2002 by toxicologist Martyn T. Smith, with backing from the shameless trial lawyers at Metzger Law Group, CERT uses junk science to target California businesses that can be sued under the state’s ill-conceived Proposition 65.”

The connection with Martyn T. Smith, was news to me, and interesting given how frequently Smith testifies for plaintiffs in cases involving even minimal benzene exposure. If correct, this website’s connecting Martyn Smith with CERT raises additional conflict-of-interest issues.

Funding of Research

Does CERT actually support research? Perhaps, after a fashion, but the money trail is as sketchy as is the ownership issue. Searching in Google Scholar turns up several publications that openly acknowledge funding from CERT. Perhaps only the young and naïve will be surprised that CERT money went to Martyn Smith, alleged founder of CERT and testifier for plaintiffs’ counsel, and to Smith’s students.12 In one instance, CERT support has been acknowledged by Martyn Smith and co-authors for the production of a meta-analysis, which can then be relied upon by Smith and other plaintiffs’ expert witnesses in benzene litigation. Although this meta-analysis credits funding from CERT, most readers of a professional journal will have little idea of the funding’s litigation provenance.13 The corresponding author of the CERT-funded meta-analysis was an official in the California state Office of Environmental Health Hazard Assessment, an office which is in a position to make decisions that help CERT in its California litigation goals.14

The funding of Martyn Smith and his students would certainly be questionable if Smith was a founder of or a participant in CERT. When Smith’s litigation opinions were challenged in one high-profile case, CERT rallied to his rescue with an amicus brief, which did not disclose any relationship between CERT and Martyn Smith, or CERT’s funding of Smith’s research. Milward v. Acuity Specialty Prods. Group, Inc., 639 F.3d 11 (1st Cir. 2011).

A current online listing at Guidestar gives Nancy Quam-Wickham as the “principal officer,” with the same EIN for CERT, as I saw five years ago. Quam-Wickham is a professor of history at California State University, in Long Beach. She seems an unlikely person to head up an organization given to research and education on “toxics.” The phone number for CERT is now 6101824891, but the mailing address is still Ralphael Metzger’s law office.

The Charity Navigator website does not rate CERT because its annual revenue is below $1 million. The website describes CERT as a 501(c)(3), with the same current address as Metzger’s lawfirm. According to Charity Navigator, CERT’s IRS 990 return listed assets of $21,880, and income of $137,354, for 2017.

So what are CERT’s educational activities? The sketchiness of CERT’s appearance as an “amicus” in Ralphael Metzger’s own lawsuits seems matched by the sketchiness of the organization’s professed educational mission. A deeper dive discovered that CERT has garnered some acknowledgements on the websites of other organizations. For instance, the Green Science Policy Institute, founded in 2008, for instance, acknowledges CERT for its “generous support” of the Institute’s work.

Some of CERT’s “educational” efforts have not fared particularly well. In the Chemtura Corporation bankruptcy, CERT attempted to intervene to assert a $9 billion claim to compensate “the public” for alleged injuries from the bankrupt’s allegedly toxic chemicals. In re Chemtura Corp., No. 09-11233, U.S. Bankruptcy Court (S.D.N.Y. 2010). Bankruptcy Judge Robert Gerber was not impressed with CERT’s educational efforts, and dismissed the entity as lacking the necessary standing to make a claim.15
