How ‘Preapproved Narratives’ Have Corrupted Science

Scientists were aghast last month when Patrick Brown, climate director at the Breakthrough Institute in Berkeley, Calif., acknowledged that he’d censored one of his studies to increase his odds of getting published.

Credit to him for being honest about something his peers also do but are loath to admit. [emphasis, links added]

In an essay for the Free Press, Mr. Brown explained that he omitted “key aspects other than climate change” from a paper on California wildfires because such details would “dilute the story that prestigious journals like Nature and its rival, Science, want to tell.”

Editors of scientific journals, he wrote, “have made it abundantly clear, both by what they publish and what they reject, that they want climate papers that support certain preapproved narratives.”

Nature’s editor, Magdalena Skipper, denied that the journal has “a preferred narrative.” No doubt the editors at the New York Times and ProPublica would say the same of their own pages.

Mr. Brown’s criticisms aren’t new. In 2005 Stanford epidemiologist John Ioannidis wrote an essay titled “Why Most Published Research Findings Are False.”

He contended that scientists “may be prejudiced purely because of their belief in a scientific theory or commitment to their own findings.”

“The greater the financial and other interests and prejudices in a scientific field, the less likely the research findings are to be true,” Dr. Ioannidis argued.

“Many otherwise seemingly independent, university-based studies may be conducted for no other reason than to give physicians and researchers qualifications for promotion or tenure.”

In addition, many scientists use the peer-review process to suppress findings that challenge their own beliefs, which perpetuates “false dogma.”

As Dr. Ioannidis explained, the more scientists there are in a field, the more competition there is to get published and the more likely they are to produce “impressive ‘positive’ results” and “extreme research claims.” …snip…

The peer-review process is supposed to flag problems in studies that get submitted to journals. But as Dr. Ioannidis explained in a Sept. 22 JAMA editorial, the process is failing:

“Many stakeholders try to profit from or influence the scientific literature in ways that do not necessarily serve science or enhance its benefits to society.”

Those “stakeholders” include the scientific journals themselves, which he notes have among the highest profit margins of any industry—by some estimates, about 40%.

Journals often don’t compensate peer reviewers, which can result in perfunctory work. The bigger problem is that reviewers often disregard a study’s flaws when its conclusions reinforce their own biases.

One result is that “a large share of what is published may not be replicable or is obviously false,” Dr. Ioannidis notes. “Even outright fraud may be becoming more common.”

As scientists struggle to publish against-the-grain research, many are turning to preprint servers—online academic repositories—to debunk studies in mainstream journals.

Yet even some of those sites, such as the Social Science Research Network, are blocking studies that don’t fit preapproved narratives.

In January 2022, Johns Hopkins University economist Steve H. Hanke reported that Covid lockdowns had little effect on deaths.

When he attempted to publish the findings on SSRN, the site turned him down. “Given the need to be cautious about posting medical content, SSRN is selective on the papers we post,” a rejection notice informed Mr. Hanke.

That’s the same response the site gave the University of California, San Francisco epidemiologist Vinay Prasad when rejecting his studies debunking widely cited Covid studies, such as one claiming Boston schools’ mask mandate reduced cases.

SSRN is run by the company Elsevier, which also publishes prominent medical journals that uniformly promote Covid orthodoxy.

Scientific journals and preprint servers aren’t selective about research quality. They’re selective about the conclusions.

If experts want to know why so many Americans don’t trust “science,” they have their answer. Too many scientists no longer care about science.
