    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?

            I guess what I’m getting at is: Is there a way you can explain why evopsych is a valid science where phrenology is not, without relying on an argument that a phrenologist would also make? That’s a tough set of criteria, but I think it’s required.

              The premise upon which it was based was later shown to be false.

                Right! So accepted “science” can become pseudoscience once further discoveries are made. I think we all agree on that. The question being debated in this thread, I think, is whether evopsych will also eventually be found to be a pseudoscience. To be clear, I am not proposing we try and guess the future, but to look at the state of the science now and extrapolate that as best we can into the future.

                I am a complete lay(wo)man here, so I’m not casting aspersions either way. I would need to do a lot more research for that. I see the other arguments devolving into semantics and rhetoric though instead of focusing on that core conceit.

                So you feel any confidence in evopsych as a science? Why or why not? And if those same arguments could be applied to phrenology prior to its official debunking, how valid is that confidence?

                  Respectfully, the point of contention appears to be between the several users who have already concluded it is a pseudoscience and myself who has not.

                  The fundamental premise on which it lies is evolution by natural selection. Yes, the possibility exists that may one day be falsified but…its pragmatic to continue as if that is unlikely.

                  That is most welcome.

                  The premises are fairly robust, and I’ve not seen a convincing argument against them. Nothing is certain so I wouldn’t describe myself as ideologically married to it.

                    That all works for me. Again, I have no opinion on evopsych itself because I just genuinely know nothing about it. Might read up a bit on the sources from the opposing narratives in the thread if I get time. I don’t think you in particular are approaching it from an unscientific or unethical point of view, but it could just be a bit of guilt by association with individuals who are using the topic nefariously. It’s not very fair, but it is common and I kinda understand why.
