Back in 1997, Francis Douglas Kelly Liddell, a real scientist in the area of asbestos and disease, had had enough of the insinuations, slanders, and bad science from the minions of Irving John Selikoff.[1] Liddell broke with the norms of science and called out his detractors for what they were doing:| Schachtman Law
Back in the first week of this month, I posted about a paper (Prada 2025),[1] which featured a so-called navigation-guide systematic review of the scientific evidence on the issue whether pregnant women’s ingestion of acetaminophen causes their children to develop autism.[2] The focus of my post was on some dodgy aspects of the Prada review, such as its anemic disclosures of interest, and its squirrely claim to have been “NIH funded.”| schachtmanlaw.com

Specific causation causes some courts to become costive, and sometimes, courts overuse so-called differential etiology as a laxative. The phrase “differential etiology” is an analogy to differential diagnosis, the reasoning process by which clinicians assess the identity of a disease or disorder. Differential etiology, like laxatives, can be overused and misused.| Schachtman Law
A few weeks ago, four scientists published what they called a “navigation guide” systematic review on acetaminophen use and autism.[1] The last named author, Andrea A. Baccarelli, is an environmental epidemiologist, who has been an expert witness for plaintiffs’ counsel in lawsuits against the manufacturers and sellers of acetaminophen. Another author, Beate Ritz, frequently testifies […]| Schachtman Law
Back in September 2023, the American Association for the Advancement of Science (AAAS), with its Center for Scientific Responsibility and Justice, sponsored a two day meeting on Scientific Evidence and the Courts. If there were notices for this conference, I missed them. The meeting presentations are now available online. Judging from camera views of the […]| Schachtman Law
The United States is in political crisis as its citizens are frogmarched into an authoritarian, illiberal, and unlawful dystopia. The seriousness of the political situation makes it difficult to focus on scientific issues, but as with past fascist regimes in history, the crisis is not limited to any one sphere of life in the United States.| Schachtman Law
There is plenty of room for a healthy science-based environmentalism, but finding the room in the American political house has always been difficult. The current administration brings together the horseshoe wacko excesses of the worm-brained Robert Kennedy, Jr., and the crony capitalism of Felonious Trump. In this toxic, post-truth milieu, environmental groups such as Sierra Club and Greenpeace are both complaining about their setbacks,[1] as well as stepping up their own propaganda.| Schachtman Law
Egilman was sufficiently clever to discern that if his “method” led to a conclusion that silicone gel breast implants cause autoimmune disease, but the Institute of Medicine, along with court-appointed experts, found no basis for a causal conclusion, then by modus tollens Egilman’s “method” was suspect and must be rejected.[1] This awareness likely explains the extent to which he went to cover up his involvement in the plaintiffs’ causation case in the silicone litigation.| schachtmanlaw.com
Victor Elliot Schwartz died late last month. His passing was marked with several obituaries, from his colleagues, friends, and family, which marked his many achievements.[1] At the defense bar, Victor was truly a thought leader and tort scholar, as well as an advocate for sensible reform. Victor’s work had tremendous influence, although sadly, because of a rapacious, rent-seeking lawsuit industry, not as much influence as it should have had.| schachtmanlaw.com

A few egregious articles in the biomedical literature have begun to endorse explicitly asymmetrical standards for inferring causation in the context of environmental or occupational exposures. Very little if anything is needed for inferring causation, and nothing counts against causation. If authors refuse to infer causation, then they are agents of “industry,” epidemiologic malfeasors, and doubt mongers.| schachtmanlaw.com
Michael Mann, formerly a climate scientist at Penn State University, is no stranger to controversy.[1] As an outspoken advocate for climate change, he has attracted close scrutiny and harsh criticism. Several right-of-center commentators criticized Mann’s work in potentially defamatory terms of “misconduct,” or “manipulation,” or data torturing. One blogger likened Mann’s conduct to Penn State’s Jerry Sandusky’s sexual abuse scandal.[2]| schachtmanlaw.com
Artificial intelligence poses some distinct dangers to lawyers as evidenced by the cockup of the lawfirm of Morgan & Morgan in submitting a brief with bogus citations. It is hard to imagine a more serious dereliction of professional duty than in submitting a brief with citations to cases that do not exist, and which no lawyer could have ever have read and selected as appropriate to cite.[1] Apparently, a user of A.I. cannot simply direct the computer to stop making stuff up, any more than we ...| schachtmanlaw.com

Back in November 2024, I posted that the fourth edition of the Reference Manual on Scientific Evidence was completed, and that its publication was imminent. I based my prediction upon the National Academies’ website that reported that the project had been completed. Alas, when no Manual was forth coming, I checked back, and the project was, and is as of today, marked as “in progress.” The NASEM website provides no explanation for the retrograde movement. Could the Manual have been DOGE...| Schachtman Law
On May 20, 2025, as announced, FDA Commissioner Martin Makary held his panel discussion on talc in food and medications.[1] The discussion lasted just under two hours, and is available on YouTube for your viewing and perhaps your amusement. Makary opened and closed the event with what could have been the plaintiffs’ opening and closing […]| Schachtman Law
A couple of weeks ago, the Wall Street Journal ran an editorial that complained that FDA Commissioner Makary had touted dodgy evidence about the potential harms of talcum powder in food and medications,[1] and called an improper public meeting to discuss his concerns. The editorial noted the procedural irregularity of convening a meeting to review evidence of the supposed harms of talc in food and drugs, without proper notice and public comment.[2] The panel met just four days after the FDA...| Schachtman Law

We now have a Secretary of Health and Human Services who has lost part of his brain to a worm and who has lied about pharmaceuticals and vaccines to advance his financial interests as a lawyer. Robert F. Kennedy, Jr. (Junior), says he will be open minded, which I suppose means that the worm can come and go as it pleases. Junior has made a career of radical environmental activism, anti-vaccine quackery, and shameless self-promotion. It is hard to imagine that those stripes will go away. In any...| Schachtman Law
Another multi-district litigation (MDL) has hit a jarring speed bump. Claims for Parkinson’s disease (PD), allegedly caused by exposure to paraquat dichloride (paraquat), were consolidated, in June 2021, for pre-trial coordination in MDL No. 3004, in the Southern District of Illinois, before Chief Judge Nancy J. Rosenstengel. Like many health-effects litigation claims, the plaintiffs’ claims in these paraquat cases turn on epidemiologic evidence. To make their causation case in the first ...| Schachtman Law
The incretin-mimetic litigation involved claims that the use of Byetta, Januvia, Janumet, and Victoza medications causes pancreatic cancer. All four medications treat diabetes mellitus through incretin hormones, which stimulate or support insulin production, which in turn lowers blood sugar. On Planet Earth, the only scientists who contend that these medications cause pancreatic cancer are those hired by the lawsuit industry.| Schachtman Law
