Studying evolutionary psychology fucked me up when I was younger. I really believed that people were out to self-maximize on behalf of their genes, that altruism wasn't real and the appearance of kindness was ultimately self-serving.

It took closeness with a lot of good people in my life for me to reject those ideas and believe in empathy and kindness again and be able to trust people.

Now my attitude is that genes screwed themselves over when they made brains capable of caring about things other than reproducing genes, and that's good from my perspective. So evolutionary psych notions give too much credit to genes (and are undisprovable pseudoscience)
