Why Smart People Believe Stupid Things
Steven Pinker explains the cognitive biases we all suffer from and how they can short-circuit rational thinking and lead us into believing stupid things. Skip to 12:15 to bypass the preamble.

Evolutionary psychology is as scientific as phrenology.
That is rather unwarranted given its still an active field and is the only accepted explanation for the origin of animal behaviour.
is the only accepted explanation for the origin of animal behaviour.
This is not true. Ethology is the general study of animal behavior. Evolutionary Psychology is specific to human behavior and is not the only approach to studying it either. Sociobiology an example of a less criticized field studying human behavior based on evolution.
This is not true. Firstly, Evolutionary Psychology is not involved with "animal" behavior in general, it is specific to human psychology.
Most of the field focuses on primates because, unsurprisingly, that's where we find most of psychology. It is wrong to say it has nothing to do with animals.
Ethology is the general study of animal behavior.
And botany is the study of plants? Every field in biology overlaps with evolution.
Also Evolutionary Psychology is not the only approach to studying human behavior either.
That's not a challenge to the premise of evopsych. If anything it sort of supports it.

It was in response to your claim that Evolutionary Psychology is the "the only accepted explanation for the origin of animal behaviour." If you want to make that claim you need to support it with some kind of reference.

Well it doesn't refute that.
If you want to make that claim you need to support it with some kind of reference.
Well ok, perhaps "only accepted explanation" was claiming too much given that a large proportion of the population believe in souls or pure blank-slatism for human behavior.
For the non-human animals though, it certainly isn't controversial to say evolution is the only explanation for the origin of behaviour. What else could it be?

there’s a lot to unpack here. firstly, there is more to human behavior than genetics/evolution, hence nature vs nurture. in other words our human experience determines our behavior in addition to genetics.
Secondly, that’s not the only claim or assumption of Evolutionary Psychology. There is lots of other stuff besides that statement that is controversial at best.

Careful you almost misquoted me there

It's a jolly good thing I was talking about non-human animals then.
in other words our human experience determines our behavior in addition to genetics.
It's a common fallacy to suppose that because an behavioural adaption has a genetic basis that therefore having the genes determines the behaviour.

Misconception #3 in the above.

Evolutionary Psychologists make claims, some of which yes are clearly lacking in explanatory power, evidence and predictions.

Yes I'm familiar with Wikipedia, if I'm just going to be talking to a search engine here I'm not terribly invested in continuing.
Phrenology wwas an active field until it wasn't.
Evolutionary psychology does start with a reasonable starting point, that some behaviors are passed genetically, but then uses that to give excuses to things that are primarily learned or discourged through social and environmental pressures. It takes something that is reasonable to speculate about as part of being biological but then twists it into justifications for racism and sexism by painting with broad brushes.

And that's the entire premise, evolution affects behaviour as well as physical attributes. The brain is not insulated against evolutionary pressures.
but then uses that to give excuses to things that are primarily learned or discourged through social and environmental pressures.
And that's where the (well earned) criticism comes from. As I said, loads of garbage is printed with "just so" stories. That does not make the premise invalid.
It takes something that is reasonable to speculate about as part of being biological but then twists it into justifications for racism and sexism by painting with broad brushes.
That's the same as saying darwinism is garbage because it led to eugenics.
Quantum mechanics isn't a garbage field because Deepak Shopra thinks it can cure baldness.

Evolutionary psychology at its core twists the concept of genetic inheritence into justifications for racism and sexism, like phrenology before it. These two examples are people taking existing science and misapplying them to things they don't have anything to do with.

That is not evopysch "at its core".
Again, you may as well describe darwinism as racist at its core.

Misapplying science doesn't make the science wrong.
As someone without skin in this game, I have a clarifying question and you seem willing to discuss. Why is phrenology junk science and evopsych not? What separates the two, for you?
The premises that underpin any science is what separates it from a pseudoscience. Phrenology posits that random bumps on your skull predict mental abilities and behaviours, why? What mechanism could possibly be responsible for such a correlation. It was based on a theory that the brain was a group of muscles and like all muscles if you worked it it got bigger. Easily shown that this wasn't the case.
A bit like chiropractry positing that all diseases are due to the bones/spine being out of alignment.
What's the premise behind evopsych? Evolution. Where does animal behavior originate from? Is it entirely spontaneous? The brain, like every other organ, is subject to evolutionary pressures. Natural selection will produce behaviour that increases survivability, and that's it.
In your mind, how do you think a phrenologist would respond to that explanation?
I couldn't possibly speculate. Is this hypothetical phrenologist the sort of scientist who adjusts their position based on new evidence?
Your reading comprehension is lacking.
There's no need to be impolite. You seem to basing your opposition to the premise of evopsych entirely on exames where it has been applied badly.
If you accept that behaviour is subject to evolutionary pressures then we are on the same page.
Name one time evo psych was used correctly and wasn't just reinforcing stereotypes.
Well I'm not sure what counts as "used correctly" but I can direct you to some highly cited respectable papers
Barrett and Kurzban 2006 https://pubmed.ncbi.nlm.nih.gov/16802884/
Provides an intro to fundamental disagreements around the scope and the mechanisms of adaptions. Long but comprehensive.
(You should he able to find a pdf of it if you don't have journal access)

Evidence that disgust evolved to protect from disease.
Edit:
I'll add this essay from Laith Al-Shawaf as well. It covers some of the misconceptions and changes the field has gone though over the last 20 years.
