The Masks Fiasco of 2020 was indeed a noteworthy example of experts-gone-wild, but my favorite is still the Monty Hall problem [0], because unlike epidemiology where proof stems from evidence-based experimentation, the Monty Hall fiasco saw a wide range of experts in mathematics/statistics—a field where truth does not require experimentation but only logic-based proof—loudly and publicly denigrate a person with no expertise in their field, only to be wrong.

But I think the an even more interesting question that this post does not cover is the role experts play in our culture. Neil Postman discusses experts at length in Technopoly: The Surrender of Culture to Technology (1992), wherein he characterizes them as basically the shaman-priests who control the Overton window [1] in a world where morality and social acceptability no longer stem from things like religion:

> ...expertise is a second important technical means by which Technopoly strives furiously to control information. There have, of course, always been experts, even in tool-using cultures. The pyramids, Roman roads, the Strasbourg Cathedral, could hardly have been built without experts. But the expert in Technopoly has two characteristics that distinguish him or her from experts of the past. First, Technopoly’s experts tend to be ignorant about any matter not directly related to their specialized area. The average psychotherapist, for example, barely has even superficial knowledge of literature, philosophy, social history, art, religion, and biology, and is not expected to have such knowledge. Second, like bureaucracy itself (with which an expert may or may not be connected), Technopoly’s experts claim dominion not only over technical matters but also over social, psychological, and moral affairs. In the United States, we have experts in how to raise children, how to educate them, how to be lovable, how to make love, how to influence people, how to make friends. There is no aspect of human relations that has not been technicalized and therefore relegated to the control of experts.

...

> The role of the expert is to concentrate on one field of knowledge, sift through all that is available, eliminate that which has no bearing on a problem, and use what is left to assist in solving a problem. This process works fairly well in situations where only a technical solution is required and there is no conflict with human purposes—for example, in space rocketry or the construction of a sewer system. It works less well in situations where technical requirements may conflict with human purposes, as in medicine or architecture. And it is disastrous when applied to situations that cannot be solved by technical means and where efficiency is usually irrelevant, such as in education, law, family life, and problems of personal maladjustment. I assume I do not need to convince the reader that there are no experts—there can be no experts—in child-rearing and lovemaking and friend-making. All of this is a figment of the Technopolist’s imagination, made plausible by the use of technical machinery, without which the expert would be totally disarmed and exposed as an intruder and an ignoramus.

> Technical machinery is essential to both the bureaucrat and the expert, and may be regarded as a third mechanism of information control. I do not have in mind such “hard” technologies as the computer—which must, in any case, be treated separately, since it embodies all that Technopoly stands for. I have in mind “softer” technologies such as IQ tests, SATs, standardized forms, taxonomies, and opinion polls. Some of these I discuss in detail in chapter eight, “Invisible Technologies,” but I mention them here because their role in reducing the types and quantity of information admitted to a system often goes unnoticed, and therefore their role in redefining traditional concepts also goes unnoticed. There is, for example, no test that can measure a person’s intelligence. Intelligence is a general term used to denote one’s capacity to solve real-life problems in a variety of novel contexts. It is acknowledged by everyone except experts that each person varies greatly in such capacities, from consistently effective to consistently ineffective, depending on the kinds of problems requiring solution. If, however, we are made to believe that a test can reveal precisely the quantity of intelligence a person has, then, for all institutional purposes, a score on a test becomes his or her intelligence. The test transforms an abstract and multifaceted meaning into a technical and exact term that leaves out everything of importance. One might even say that an intelligence test is a tale told by an expert, signifying nothing. Nonetheless, the expert relies on our believing in the reality of technical machinery, which means we will reify the answers generated by the machinery. We come to believe that our score is our intelligence, or our capacity for creativity or love or pain. We come to believe that the results of opinion polls are what people believe, as if our beliefs can be encapsulated in such sentences as “I approve” and “I disapprove."
