Psychology has an embarrassing history.

It really doesn't?

Half their studies aren't reproducible.

Replicable*, and also see here.

Their most famous study is basically a fraud.

Do you mean the Stanford prison experiment, which is famous because of how terrible it was? The one that's taught in Psych 101 classes as a lesson on ethics and how not to design an experiment? Because while I would argue it's not the most famous study, the entire reason it's famous is because it was so shittily designed that psychologists going forward took lessons from it. No one's holding that up to say "Wow, look at this great study we, the field of psychology, collectively did."

They're behind lobotomies

That was psychiatry and neurology, but I don't expect you to know the difference.

They're behind the Satanic panic

That a random quack psychiatrist came out and publicized this doesn't mean that "the field of psychology" is behind the Satanic panic. Dr. Oz is a fraud who used his platform to sell bullshit supplements; does that make the field of medicine "behind" homeopathy?

They're behind eugenics

This literally isn't true, or at least it's a ridiculous half-truth to put psychology at the forefront of eugenics. Eugenics is – surprise, surprise – rooted in biology after inheritance became more widely understood (read: we knew just enough to be dangerous). Eugenics had its hand in basically every natural science, and so you'll find occasional psychologists like Henry H. Goddard showing up, but you'll see biologists, statisticians, politicians, and so forth. Eventually eugenics spread into fields like psychiatry (note: different from psychology), but "they're behind eugenics" is absolute fucking horseshit that you fail to back up with literally anything.

I’m not anti-intelectual [sic] or a Scientologist or anything

Uh-huh...

I guess what I’m trying to say is that psychologists like Jordan Peterson might want to clean up their own room before trying to lecture the rest of us.

Why are you bringing up Jordan Peterson? Peterson is widely despised among psychologists, he no longer works at the University of Toronto, and instead of contributing research to the field or engaging in clinical practice, he puts out self-help sludge. "I'm not an anti-intelectual, but I'm going to take an entire century-old field of science and compress it into Philip Zimbardo(?) and Jordan Peterson so I can say that science bad actually."
