I dislike these threads. They encourage and reward ill thought out contrarian (often straight up crackpot) ideas. Correcting them is a large cost, in part because convincing an audience doesn't require arguing things that are true, it merely requires arguing things that take more time to refute than to assert. I'd rather not get tangled up in object level for this reason by citing real examples but here is an example of the kind of idea I would expect to see here.

Made up crazy idea (that I expect some people here would endorse):

"Get rid of research ethics boards, they prevent useful research from being done that would benefit society out of an ill founded fear of us becoming the Nazis"

This sort of argument ignores the history behind why research ethics boards exist, and is usually asserted by people who are ignorant of the actual guidelines that research ethics boards abide by. It's also usually asserted without knowledge of the actual abuses of patient trust that were committed before research ethics guidelines were established), which include withholding known treatments and doing liver toxicity study in children without telling them (quite an extensive one in which biopsies were taken, and upon recovery, liver toxicity was re-induced leading to damage lasting at least a month).

(Of course, it took me much longer to write that response than to make the initial claim)
