History of Silicosis Litigation

January 31st, 2019

“Now, Silicosis, you’re a dirty robber and a thief;
Yes, silicosis, you’re a dirty robber and a thief;
Robbed me of my right to live,
and all you brought poor me is grief.
I was there diggin’ that tunnel for just six bits a day;
I was diggin’ that tunnel for just six bits a day;
Didn’t know I was diggin’ my own grave,
Silicosis was eatin’ my lungs away.”

Josh White, “Silicosis Is Killin’ Me (Silicosis Blues)” (1936)

Recently, David Rosner, labor historian, social justice warrior, and expert witness for the litigation industry, gave the Fielding H. Garrison Lecture, in which he argued for the importance of the work that he and his comrade-in-arms, Gerald Markowitz, have done as historian expert witnesses in tort cases.¹ Although I am of course grateful for the shout out that Professor Rosner gives me,² I am still obligated to call him on the short-comings of his account of silicosis litigation.³ Under the rubric of “the contentious struggle to define disease,” Rosner presents a tendentious account of silicosis litigation, which is highly misleading, for what it says, and in particular, for it omits.

For Rosner’s self-congratulatory view of his own role in silicosis litigation to make sense, we must imagine a counterfactual world that is the center piece of his historical narrative in which silicosis remains the scourge of the American worker, and manufacturing industry is engaged in a perpetual cover up.

Rosner’s fabulistic account of silicosis litigation and his role in it falls apart under even mild scrutiny. The hazards of silica exposure were known to Josh White and the entire country in 1936. Some silicosis litigation arose in the 1930s against employers, but plaintiffs were clearly hampered by tort doctrines of assumption of risk, contributory negligence, the fellow-servant rule. To my knowledge, there were no litigation claims against remote suppliers of silica before the late 1970s, when courts started to experiment with hyperstrict liability rules.

Eventually, the litigation industry, buoyed by its successes against asbestos-product manufacturers turned their attention to silica sand suppliers to foundries and other industrial users. Liability claims against remote suppliers of a natural raw material such as silica sand, however, made no sense in terms of the rationales of tort law. There was no disparity of information between customer and supplier; the customer, plaintiffs’ employer was not only the cheapest and most efficient cost and risk avoider, the employer was the only party that could control the risk. Workers and their unions were well aware of the hazards of working in uncontrolled silica-laden workplaces.

Although employer compliance with safety and health regulations for silica exposure has never been perfect, the problem of rampant acute silicosis, such as what afflicted the tunnel workers memorialized by Josh White, is a thing of the past in the United States. The control of silica exposures and the elimination of silicosis are rightly claimed to be one of the great public health achievements of the 20^th century. See Centers Disease Control, “Ten Great Public Health Achievements — United States, 1900-1999,” 48 Morbidity & Mortality Weekly Report 241 (April 02, 1999).

Interestingly, after World War II, silicosis has been a much greater problem in the communist countries, such as China, the countries that made up the Soviet Union. Rosner and Markowitz, however, like the leftist intellectuals of the 1950s who could not bring themselves to criticize Stalin, seem blind to the sorry state of workplace safety in communist countries. Their blindness vitiates their historical project, which attempts to reduce occupational diseases and other workplace hazards to the excesses of corporate capitalism. A fair comparison with non-capitalist systems would reveal that silicosis results from many motives and conditions, including inattention, apathy, carelessness, concern with productivity, party goals, and labor-management rivalries. In the case of silicosis, ignorance of the hazards of silica is the least likely explanation for silicosis cases arising out of workplace exposures after the mid-1930s.

In the United States, silicosis litigation has been infused with fraud and deception, not by the defendants, but by the litigation industry that creates lawsuits. Absent from Rosner’s historical narratives is any mention of the frauds that have led to dismissals of thousands of cases, and the professional defrocking of any number of physician witnesses. In re Silica Products Liab. Litig., MDL No. 1553, 398 F.Supp. 2d 563 (S.D.Tex. 2005).

Nor does Rosner deign to discuss the ethical and legal breaches committed by the plaintiffs’ counsel in conducting radiographic screenings of workers, in the hopes of creating lawsuits. With the help of unscrupulous physicians, these screenings were unnaturally successful not only in detecting silicosis that did not exist, but in some cases, in transmuting real asbestosis into silicosis.⁴

Many silicosis cases in recent times were accompanied by more subtle frauds, which turned on the “failure-to-warn” rhetoric implicit in the Restatement (Second) of Torts § 402A. Consider the outbreak of silicosis litigation in western Pennsylvania, in the mid-1980s. Many of the men who claimed to have silicosis had significant silica exposure at the Bethlehem and U.S. Steel foundries in the Johnstown areas. Some of the claimants actually had simple silicosis, although discovery of these claimants’ workplace records revealed that they had been non-compliant with workplace safety rules.

The Johnstown, Cambria County, cases were not the result of unlawful medical screenings, paid for by plaintiffs’ lawyers and conducted by physicians of dubious integrity and medical acumen. Instead, the plaintiffs’ lawyers found their claimants as a result of the claimants’ having had previous workers’ compensation claims for silicosis, which resulted after the workers were diagnosed by employer medical screening programs.

Cambria County Courthouse in Ebensburg, PA (venue for an outbreak of silicosis litigation in the 1980s and early 1990s⁵)

The first of the foundrymen’s cases was set for trial in 1989, 30 years ago, in Cambria County, Pennsylvania. The silica cases were on the docket of the President Judge, the Hon. Joseph O’Kicki, who turned out to be less than honorable. Just before the first silica trial, Judge O’Kicki was arrested on charges of corruption, as well as lewdness (for calling in his female staff while lounging in chambers in his panties).

As a result of O’Kicki’s arrest, the only Cambria Country trial we saw in 1989 was the criminal trial of Judge O’Kicki, in Northampton County. In April 1989, a jury found O’Kicki guilty of bribery and corruption, although it acquitted him on charges of lewdness.⁶ Facing a sentence of over 25 years, and a second trial on additional charges, O’Kicki returned to the land of his forebears, Slovenia, where he lived out his days and contributed to the surplus population.⁷

Whatever schadenfreude experienced by the defendants in the Cambria County silicosis litigation was quickly dispelled by the assignment of the silica cases to the Hon. Eugene Creany, who proved to be an active partisan for the plaintiffs’ cause. Faced with a large backlog of cases created by the rapacious filings of the Pittsburgh plaintiffs’ lawfirms, and Judge O’Kicki’s furlough from judicial service, Judge Creany devised various abridgements of due process, the first of which was to consolidate cases. As a result, the first case up in 1990 was actually three individual cases “clustered” for a single jury trial: Harmotta, Phillips, and Peterson.⁸ To poke due process in both eyes, Judge Creany made sure that one of the “clustered” cases was a death case (Peterson).

Jury selection started in earnest on April 2, 1990, with opening statements set for April 4. In between, the defense made the first of its many motions for mistrial, when defense lawyers observed one of the plaintiffs, Mr. Phillips, having breakfast with some of the jurors in the courthouse cafeteria. Judge Creany did not seem to think that this pre-game confabulation was exceptional, and admonished the defense that folks in Cambria County are just friendly, but they are fair. Trial slogged on for four weeks, with new abridgments of due process almost every day, such as forcing defendants, with adverse interests and positions, into having one direct- and one cross-examination of each witness. The last motion for mistrial was provoked by Judge Creany’s walking into the jury room during its deliberations, to deliver doughnuts.

At the end of the day, in May 1990, the jury proved to be much fairer than the trial judge. Judge Creany instructed the jury that “silica was the defect,” and on other novel points of law. Led by its foreman, a union organizer for the United Mine Workers, the jury returned a defense verdict in the Peterson case, which involved a claim that Mr. Peterson’s heart attack death case was caused by his underlying silicosis. In the two living plaintiffs’ cases, the jury found that the men had knowingly assumed the risk of silicosis, but at the judge’s insistence, the jury proceeded to address defendants’ liability, and to assess damages, in the amount of $22,500, in the two cases.

Pennsylvania’s appellate courts took a dim view of plaintiffs’ efforts to hold remote silica suppliers responsible for silicosis arising out of employment by large, sophisticated steel manufacturers. The Superior Court, Pennsylvania’s intermediate appellate court, reversed and remanded both plaintiffs’ verdicts. In Mr. Harmotta’s case, the court held that his action was collaterally estopped by a previous workman’s compensation judge’s finding that he did not have silicosis. In Mr. Phillip’s case, the court addressed the ultimate issue, whether a remote supplier to a sophisticated intermediary can be liable for silicosis that resulted from the intermediary’s employment and use of the supplied raw material. In what was a typical factual scenario of supply of silica to foundry employers, the Superior Court held that there was no strict or negligence liability for the employees’ silicosis.⁹ The Pennsylvania Supreme Court declined to hear Harmotta’s appeal on collateral estoppels, but heard an appeal in Phillips’ case. The Supreme Court pulled back from the sophisticated intermediary rationale for reversal, and placed its holding instead on the obvious lack of proximate cause between the alleged failure to warn and the claimed harm, given the jury’s special finding of assumed risk.¹⁰

One of plaintiffs’ counsel’s principal arguments, aimed at the union organizer on the jury, was that even if a warning to the individual plaintiffs might not have changed their behavior, a warning to the union would have been effective. The case law involving claims against unions for failing to warn have largely exculpated unions and taken them out of the warning loop. Given this case law, plaintiffs’ argument was puzzling, but the puzzlement turned to outrage when we learned after the first trial that Judge Creany had been a union solicitor, in which role, he had regularly written to U.S. Steel in Johnstown, to notify the employer when one of the local union members had been diagnosed with silicosis.

The next natural step seemed to list Judge Creany as a percipient fact witness to the pervasive knowledge of silicosis among the workforce and especially among the union leadership. Judge Creany did not take kindly to being listed as a fact witness, or being identified in voire dire as a potential witness. Still, the big lie about failure to warn and worker and labor union ignorance had been uncovered. Judge Creany started to delegate trials to other judges in the courthouse and to bring judges in from neighboring counties. The defense went on win the next dozen or so cases, before the plaintiffs’ lawyers gave up on their misbegotten enterprise of trying to use Pennsylvania’s hyperstrict liability rules to make remote silica suppliers pay for the fault of workers and their employers.

You won’t find any mention of the Cambria County saga in Rosner or Markowitz’s glorified accounts of silicosis litigation. The widespread unlawful screenings, the “double dipping” by asbestos claimants seeking a second paycheck for fabricated silicosis, the manufactured diagnoses and product identification do not rent space in Rosner and Markowitz’s fantastical histories.

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.¹¹Hill’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!

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.

Burton, 567 F. Supp. 2d 121, 130-31 (D.D.C. 2008) (excluding Dr. Shoemaker’s theories as lacking general acceptance and reliability; listing Virginia, Florida, and Alabama as states in which courts have rejected Shoemaker’s theory).

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 (1^st 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

PubMed Refutes Courtroom Historians

February 11th, 2018

Professors Rosner and Markowitz, labor historians, or historians laboring in courtrooms, have made a second career out of testifying about other people’s motivations. Consider their pronouncement:

“In the postwar era, professionals, industry, government, and a conservative labor movement tried to bury silicosis as an issue.”

David Rosner & Gerald Markowitz, Deadly Dust: Silicosis and the Politics of Occupational Disease in the Twentieth Century America 213 (Princeton 1991); Gerald Markowitz & David Rosner, “Why Is Silicosis So Important?” Chap. 1, at 27, in Paul-André Rosental, ed., Silicosis: A World History (2017). Their accusation is remarkable for any number of reasons,¹ but the most remarkable is that their claim is unverified, but readily falsified.²

Previously, I have pointed to searches in Google’s Ngram Book viewer as well as in the National Library of Medicine’s database (PubMed) on silicosis. The PubMed website has now started to provide a csv file, with articles counts by year, which can be opened in programs such as LibreOffice Calc, Excel, etc, and then used to generate charts of the publication counts over time.

Here is a chart generated form a simple search on <silicosis> in PubMed, with years aggregated over roughly 11 year intervals:

The chart shows that the “professionals,” presumably physicians and scientists were most busy publishing on, not burying, the silicosis issue exactly when Rosner and Markowitz claimed them to be actively suppressing. Many of the included publications grew out of industry, labor, and government interests and concerns. In their book and in their courtroom performances,, Rosner and Markowitz provide mostly innuendo without evidence, but their claim is falsifiable and false.

To be sure, the low count in the 1940s may well result from the relatively fewer journals included in the PubMed database, as well as the growth in the number of biomedical journals after the 1940s. The Post-War era certainly presented distractions in the form of other issues, including the development of antibiotics, chemotherapies for tuberculosis, the spread of poliomyelitis and the development of vaccines for this and other viral diseases, radiation exposure and illnesses, tobacco-related cancers, and other chronic diseases. Given the exponential expansion in scope of public health, the continued interest in silicosis after World War II, documented in the PubMed statistics, is remarkable for its intensity, pace Rosner and Markowitz.

1 “Conspiracy Theories: Historians, In and Out of Court” (April 17, 2013). Not the least of the reasons the group calumny is pertinent is the extent to which it keeps the authors gainfully employed as expert witnesses in litigation.

2 See also CDC, “Ten Great Public Health Achievements – United States, 1900 – 1999,” 48(12) CDC Morbidity and Mortality Weekly Report 241 (April 02, 1999)(“Work-related health problems, such as coal workers’ pneumoconiosis (black lung), and silicosis — common at the beginning of the century — have come under better control.”).

Fake Friends and Fake Followers

January 28th, 2018

In the Black Mirror production of Nosedive, based upon a short story by Charlie Brooker, a young woman named Lacie lives in a world in which social media approval metrics determine social, economic, and political opportunities. Every interaction is graded on a scale from one to five. Lacie’s approval rating is slipping, thus jeopardizing her participation in her friend’s wedding, and she is determined to improve her rating. She tries her best to be “nice,” and then enlists a ratings coach, but her efforts cannot stop her approval rating from its nosedive. Perhaps if Lacie had greater financial resources, she could have improved her ratings by paying people to like her on social media.

Would people really pay for the appearance of social approval? “Celebrities, athletes, pundits and politicians have millions of fake followers,” and they paid for them. Thus announces the New York Times in an exposé of the practice of paying for followers on social media.¹ Perhaps even the President has paid for fake followers who are mere bots. Maybe bots are the only friends he has.

Although I am skeptical of the utility of Facebook and Twitter, I have come reluctantly to admit that these and other social media – even blogs – have some utility if properly used. The business of buying followers, however, is just plain sick.

Finally, Eric Schneiderman has announced an investigation into an issue of some importance. He is investigating Devumi, a company that he claims sells fake followers on social media. The company is alleged to have created over 55,000 bots based upon living people and their identifying features.²

Stealing identities and selling fake followers is deplorable, and Scheiderman’s crusade is a laudable exercise of prosecutorial discretion. But so is buying fake followers to lard up one’s social media metrics. The crime involves two separate criminal acts, and we should not lose sight of the fraudulent nature of the representations about inflated number of followers. It takes two parties to enter the contract to defraud the public. Devumi’s clients may well be in pari delicto.

Let us hope that when Schneiderman opens the books at Devumi, he will have the fortitude to tell us which “celebrities, athletes, pundits, and politicians” have been juking their stats. Schneiderman’s investigation has the promise of making Eliot Spitzer’s commercial transactions look like child’s play. Inquiring minds want to know who would buy a friend or a follower.

Manufacturing Consent

December 2nd, 2017

David Michaels along with other “political” scientists, and the lawsuit industry, have worked assiduously over the last several decades to delegitimize discussion, debate, and controversy over scientific claims.¹ Their key goals have been to attempt to disqualify manufacturing industry and any scientist with the slightest manufacturing industry contact. Their attempts to disqualify other interlocutors is, however, highly asymmetrical. If those with connections to manufacturing industry criticize studies or causal conclusions, then we hear that the criticism is corrupt. If those with connections to manufacturing industry embrace studies that show favored associations, or causal conclusions, then we hear that the embrace of advocacy positions was an “admission,” reluctantly given but “forced” by overwhelming evidence. In other words, the attempts to disqualify interlocutors are made only when the speakers articulate criticism of the claims of advocacy science.

David Zaruk has argued that the techniques used to squelch criticism of advocacy science bear an uncanny resemblance to the techniques used by fascists generally. See David Zaruk, “Ten Practices Linking Environmentalism with Fascism,” Riskmonger (Dec. 2, 2017). Although Zaruk’s argument may appear hyperbolic, there is no denying that advocacy scientists (not merely in the field of environmentalism) have used the rhetorical devices that are used by intellectual bullies everywhere. In the case of advocacy scientists, one of their key maneuvers has been to privilege advocacy scientists who speak for their favored positions, for the lawsuit industry, and for self-styled public interest groups by ignoring their potential conflicts of interest, while diminishing the substantive content of all “opposition” voices by pejoratively characterizing their opponents’ motivation as “manufacturing doubt.” Of course, the deepest irony is that before there was manufacturing doubt, there was manufacturing consent.² The unkindest thing that can, and must be said, of the current enthusiasm for attacking dissident scientists is not that the attacks are fascist, but that they are unscientific.

The likes of David Michaels have sought to manufacture consent on various health effects issues, by selectively and asymmetrically accusing scientists of conflicts of interest, or trying to pervert the course of science. These attacks on “dissidents” assume the truth of the contested causal conclusions, and then proceed to call out the dissidents for casting doubt on the “truth” in favor of falsehood. What this mobbing of dissidents ignores is the basic normative structure of science, which requires doubt.

One of the first sociologists of science, Robert Merton, described four institutional imperatives of science: universality, communitarianism, disinterestedness, and “organized skepticism.”³ Scientists are committed to methodologies and an institutional ethos that require searching scrutiny of claims to scientific knowledge. The scientific advocates who would silence criticism with accusations of “manufacturing doubt” ignore the epistemic importance of dissent and disagreement in science. The prevalent attempts to squelch dissent as “manufacturing doubt” is thus unscientific and dangerous.⁴

David Egilman and Friends Circle the Wagons at the International Journal of Occupational & Environmental Health

May 4th, 2017

Andrew Maier is an associate professor in the Department of Environmental Health, in the University of Cincinnati. Maier received his Ph.D. degree in toxicology, with a master’s degree in industrial health. He is a Certified Industrial Hygienest and has published widely on occupational health issues. Earlier this year, Maier was named the editor-in-chief of the International Journal of Occupational and Environmental Health (IJOEH). See Casey Allen, “Andy Maier Named Editor of Environmental Health Journal” (Jan. 18, 2017).

Before Maier’s appointment, the IJOEH was, for the last several years, the vanity press for former editor-in-chief David Egilman and “The Lobby,” the expert witness brigade of the lawsuit industry. Egilman’s replacement with Andrew Maier apparently took place after the IJOEH was acquired by the scientific publishing company Taylor & Francis, from the former publisher, Maney.

The new owner, however, left the former IJOEH editorial board, largely a gaggle of Egilman friends and fellow travelers in place. Last week, the editorial board revoltingly wrote [contact information redacted] to Roger Horton, Chief Executive Officer of Taylor & Francis, to request that Egilman be restored to power, or that the current Editorial Board be empowered to choose Egilman’s successor. With Trump-like disdain for evidence, the Board characterized the new Editor as a “corporate consultant.” If Maier has consulted with corporations, his work appears to have rarely if ever landed him in a courtroom at the request of a corporate defendant. And with knickers tightly knotted, the Board also made several other demands for control over Board membership and journal content.

Andrew Watterson wrote to Horton on behalf of all current and former IJOEH Editorial Board members, a group heavily populated by plaintiffs’ litigation expert witnesses and “political” scientists, including among others:

Arthur Frank

Morris Greenberg

Barry S. Levy

David Madigan

Jock McCulloch

David Wegman

Barry Castleman

Peter Infante

Ron Melnick

Daniel Teitelbaum

None of the signatories apparently disclosed their affiliations as corporate consultants for the lawsuit industry.

Removing Egilman from control was bad enough, but the coup de grâce for the Lobby came earlier in April 2016, when Taylor & Francis notified Egilman that a paper that he had published in IJOEH was being withdrawn. According to the petitioners, the paper, “The production of corporate research to manufacture doubt about the health hazards of products: an overview of the Exponent Bakelite simulation study,” was removed without explanation. See “Public health journal’s editorial board tells publisher they have ‘grave concerns’ over new editor,” Retraction Watch (April 27, 2017).

According to Taylor & Francis, the Egilman article was “published inadvertently, before the review process had been completed. On completing that review, it was decided the article was unsuitable for publication in the journal.” Id. Well, of course, Egilman’s article was unlikely to receive much analytical scrutiny at a journal where he was Editor-in-Chief, and where the Board was populated by his buddies. The same could be said for many articles published under Egilman’s tenure at the IJOEH. Taylor & Francis owes Egilman and the scientific and legal community a detailed statement of what was in the article, which was “unsuitable,” and why. Certainly, the law department at Taylor & Francis should make sure that it does not give Egilman and his former Board of Editors grounds for litigation. They are, after all, tight with the lawsuit industry. More important, Taylor & Francis owes Dr. Egilman, as well as the scientific and legal community, a full explanation of why the article in question was unsuitable for publication in the IJOEH.

Quackers & Cheese – Trump Picks Kennedy to Study Vaccine Safety

January 11th, 2017

Science necessarily involves a willingness to follow evidence to whatever conclusions are warranted, if conclusions properly can be had. When it comes to vaccination conspiracies, Democrats have it in their political DNA to distrust pharmaceutical companies that research, develop, and manufacture vaccines. The current Republican party, which has been commandeered by theocrats and populists, see vaccination as federal government aggrandizement, and resist vaccination policy as contrary to God’s will. Science is often the loser in the cross-fire.

And so we now have the public spectacle of watching the left and the right join in similar scientific apostasies. Consider how both McCain and Obama both suggested that vaccines and autism were related in the 2008 election. (Although both candidates were to some extent slippery in their suggestions, which might have been appropriate given how little they knew about the controversies.) And consider Michelle Bachmann was converted to a similar view about the HPV vaccine on the basis of a woman’s anecdote about her child. And then on the far left, you have the uplifting story of Robert F. Kennedy Jr, and his brief on how thimerosal supposedly causes autism.

So it should be no surprise that Donald Trump, a Birther, a Mirther, a mid-night Twitterer, should embrace the anti-vaccination movement. Trump has made it clear that he rejects evidence-based policy, and so no one should expect him to embrace a scientific policy that is driven by high-quality scientific evidence. According to Kennedy, Trump wants Kennedy to head up a “commission on vaccine safety and scientific integrity.” Michael D. Shear, Maggie Haberman & Pam Belluckjan, “Anti-Vaccine Activist Says Trump Wants Him to Lead Panel on Immunization Safety,” N.Y. Times (Jan. 10, 2017); Domenico Montanaro, “Despite The Facts, Trump Once Again Embraces Vaccine Skeptics,” National Public Radio (Jan. 10, 2017).

Who needs the National Academy of Medicine when you can put a yutzball lawyer in charge of a “commission”?

Some of the media refer to Robert F. Kennedy Jr. as a vaccine skeptic, but their terminology is grossly inaccurate and misleading. Kennedy is a vaccine denier; he has engaged in a vitriolic campaign against the safety and efficacy of vaccines. He has aligned himself with the most extreme deniers of science, medicine, and public safety, including the likes of Andrew Wakefield and Jenny McCarthy. Kennedy has not merely engaged hyperbolic rhetoric against vaccines, he has used his radio show on the lawsuit industry’s Ring of Fire, to advance his campaign against public health as well as to shill for the lawsuit industry on other issues. See “RFK, Jr.: Science Shows That Autism — Mercury Link Exists – PT. ½,” Ring of Fire (Mar 8, 2011).

Kennedy should not be characterized as a skeptic, when he is a shrill ideologue, for whom science has no method that he is bound to respect. Back in July 2005, Kennedy published an article, “Deadly Immunity,” in both Rolling Stone and on Slate’s website. The article was a hateful screed against Big Pharma and government health agencies for an alleged conspiracy to hide the autism risks of thimerosal preservatives in vaccines. Several years later, on January 16, 2011, Salon retracted the article. See “https://en.wikipedia.org/wiki/Deadly_Immunity” entry in Wikipedia. See also Phil Plait, “Robert F. Kennedy Jr.: Anti-Vaxxer,” Slate (June 5 2013) (describing Kennedy as a full-blown anti-vaccination conspiracy theorist); Rahul K. Parikh, M.D., “Inside the vaccine-and-autism scare: A pediatrician traces the rise of the anti-vaccine movement that falsely linked thimerosal with autism and turned parents away from the most lifesaving medicine in history,” Salon (Sept. 22, 2008); Keith Kloor, “Is Robert F. Kennedy Jr. Anti-Science?” Discover Magazine (June 1, 2013); Steven Novella, “RFK Jr.s Autism Conspiracy Theory,” (Jun 20 2007).

Back in 2008, President Obama apparently considered Robert Kennedy for a cabinet-level position, but on sober reflection, thought better of it. See Steven Novella, “Politics and Science – The RFK Jr. Test,” (Nov. 07 2008). The Wall Street Journal, joined by many others, are now urging Trump to think harder and better about the issue, perhaps with some evidence as well. See Alex Berezow & Hank Campbell, “Ignore Anti-Vaccine Hysteria, Mr. Trump: Robert F. Kennedy Jr.’s conspiracy theories have no place in the White House,” Wall Street J. (Jan. 10, 2017).

In Queue for the Q

January 1st, 2017

All right, this has nothing to do with law, evidence, or statistics, but what a great day for New York and the Upper Eastside. Today, the “Second Avenue Line,” an extension of the Q subway line opened for business.

The local radio stations announced that the MTA would give away free subway day passes at 11 a.m., at the new 86^th street station. Even before the hour, a queue formed of locals eager for a free first ride on the Second Avenue line. At 11:15 a.m., Congresswoman Carolyn Mahoney arrived. She did not greet anyone in the queue; rather, she planted herself in front of TV cameras to which she made kissy faces and self-congratulatory noises. Of course, the MTA has little or nothing to do with the federal government, and the rationale for her presence was curiously absent. Mayor DeBlasio, who lives but four blocks away in Gracie Mansion, however could not be bothered to show up. No doubt he was still in bed, and nursing a hang over.

Not only did Mahoney did speak to anyone in the queue, going to the Q, her remarks for the TV and radio media were whispered into microphones. Standing about four feet away from her, I could barely hear a word she said. Surely no one behind me heard her, and she clearly did not care. Mahoney had greater audiences in mind, and no apparent interest in actually interacting with her constituents. Perhaps she was hung over from New Year’s Eve festivities.

With Congresswoman Mahoney were her minions, who started to hand out the coveted free passes, but not to the people who had peacefully assembled and patiently waited in line. Because the TV cameras set up around Mahoney, her minions had to hand out cards close to her and to the cameras so that the TV audiences would see the handouts as Mahoney’s largesse. There was a visually impaired woman at the front of the line, with her guide dog, Kudo, but they were ignored by Mahoney and her aides, as well as by the media. Finally, in a Bonfire of the Vanities moment, as Mahoney started to drift away, a boisterous woman pushed her way in front of the cameras, while exclaiming that she wasn’t being pushy, because, after all, she had bona fide press credentials. So the TV cameras shifted to her, and she, a media person, was then interviewed by the media. Where was Tom Wolfe to capture this wonderful New York moment?

Guide Dog Kudo Leads the Way as First Dog Rides the Second Avenue Line on New Year’s Day, 2017

Finally, at noon, the police tape was unceremoniously pulled away, and the Second Avenue line was opened to the hoi polloi. The subway cars were not new, but were appropriately clean for the occasion. The first downtown train today on the new Second Avenue line left from 86^th Street, amid great fanfare and cheering. When the subway reached 72^nd Street, the conductor held the train for almost 15 minutes due to traffic on the line. Huh? I suspect that the conductor wanted the passengers to have that real MTA experience.

The subway stations at 96^th, 86^th, 72^nd, and 63^rd streets all had that wonderful new subway station smell, almost as good as a new BMW. And each of these four stations has become a wonderful museum of public art, each worth an MTA card for the price of admission. See Muoio, “New York’s long-awaited Second Avenue subway features some incredible artwork” (Dec. 30, 2016). I will leave the exhibits for the art critics to describe, except to say that the 86^th, 72^nd, and 63^rd street stations have become outstanding artistic tributes to New York City and its residents. Thankfully, there was no sign of any likeness of Donald Trump.

A hundred years late, the Second Avenue subway has arrived. It does not go as far as it should, but perhaps Governor Cuomo will take a page out the Robert Moses playbook and use the stub as leverage to get the whole thing done. The Governor seems to have the right stuff to get infrastructure programs completed. If infrastructure were up to Mayor DeBlasio, we would still be waiting for the Second Avenue line along with the resurrection of Robert Moses himself.
