JONATHAN TURLEY: The Icarian Gene: The Rise and Fall of the Expert Class.

In his concurrence in United States v. Skrmetti, a case upholding Tennessee’s ban on adolescent transgender treatments, Thomas called for his colleagues to stand against an “expert class” that has dictated both policy and legal conclusions in the United States.

The reference to “experts” is often used to insulate an opinion as self-evidently true on a given question when they speak as a group. It distinguishes the informed from the casual; the certifiably authoritative from the merely interested. Yet, what constitutes an “expert” can be little more than an advanced degree, and the “overwhelming opinion of experts” can be little more than groupthink.

Thomas warned his colleagues that “[t]here are particularly good reasons to question the expert class here, as recent revelations suggest that leading voices in this area have relied on questionable evidence, and have allowed ideology to influence their medical guidance.”

Indeed, those “good reasons” have become increasingly obvious to those outside of the Beltway. The public saw experts line up during the pandemic to support mandatory uses of surgical masks, shutting down schools, and requiring the ruinous six-foot rule of separation. Many of these rules were later found lacking in scientific support. At the same time, dissenting experts, including the signatories of the Great Barrington Declaration, were blacklisted, censored, or fired for challenging these views.

We have seen the same orthodoxy on issues ranging from gender dysphoria to COVID measures.

And the results are rarely — never? — as beneficial as you’d expect to get from experts. Unless, of course, their real expertise is in leftwing orthodoxy.
