This article is about MD doctors, not scientists (although there may be some MD-PhDs in it, and yes MDs can get research positions).
MD doctors poll at extraordinarily high levels of trust, over almost any other professional group in the United States. So it really isn't correct to directly link this article's topic to "distrust". The effect you're talking about may exist in science, but this article is essentially a counter example to the effect you propose: clinicians publishing bullshit, but retain a high level of public trust.
Especially because the article is basically entirely quoting practicing scientists who identified this problem in the first place! More real scientific training or collaborating for clinicians who want to (or have to) do research could potentially improve the situation.
>> MD doctors poll at extraordinarily high levels of trust
"1966–2012: Historical Harris Polls show a steady long-term erosion, with "great confidence" in the leaders of medicine dropping from 73% to 34% over these decades."
"2021–2024: According to Gallup data, the perceived "honesty and ethics" of doctors fell 14 points, dropping to 53%—the lowest seen since the mid-1990s."
"2024–Present: Major Johns Hopkins University / JAMA Network Open research highlights an overall institutional drop from 71.5% in April 2020 down to 40.1% across socioeconomic groups"
MD doctors (and even to a large extent DO doctors nowadays) are philosophically grounded on science. An MD fundamentally practices science. That used to be one of the key differences between MD and DO physicians, but science has been so successful at advancing the standard of care that DOs cannot ignore it anymore. That's just to say that MDs are expected to be fluent in science and it's not some arbitrary expectation of bureaucracy run amok.
Due to the high trust they get from the public, I have run into many MDs who are used to making unfounded assertions with little pushback.
Why is this? MDs are among the people I trust the least, along with lawyers, financial advisors, and real-estate agents.
Information asymmetry
"fasting is a disaster for the body" says radio MD with complete confidence.. one of my personal favorites
An MD does not practice science.
Science is a process of discovering new knowledge through experiments.
An MD is much more akin to an engineer that applies scientific knowledge (and yes, some proportion of both MDs and engineers do create new knowledge through experiments and thus do science, but it's not the baseline expectation).
