We didn't even know what "junk DNA" did until like 25 years ago. We've discovered a couple new body parts in the last 50 years. We don't have any real understanding of how basic, foundational parts of medicine work - things like anesthesia and antidepressants and even pain differences between men and women. Tests are regularly performed on highly homogenous groups, or even tested on groups completely different from the target audience. The US allows us to advertise medicines on TV, and this gets people thinking they have some vague understanding of medicine - which they do not. I mean, maybe the unreasonably smart audience of this site may, but for the extreme majority of Americans, they do not.

I think our massive advancement in the computer industry has confused people into thinking other industries which use computers are also advanced, but this is not the case. Pharmacology is an extremely immature field.

Edit: I think the only field more immature than this would be psychology? And I don't think many are silly enough to trust a field who still worships a dude that believed every thought you had was somehow actually about sex, and has made zero advancements beyond borrowing meditation and a few other ideas from other cultures.
