It's strange. We know that instincts, hormones, and other aspects of our biology have a tremendous influence on our thoughts and behaviors, but there doesn't seem to be a lot of effort to use that to problem-solve. There's evolutionary psychology, but given the fraction of human problems traceable to maladaption to the modern world, one would think "evolutionary anthropo-sociology" would a foundational pillar of science. Like, why doesn't "humans didn't evolve to sleep in a room by themselves at the age of four" carry as much weight as "don't let your kids eat lead paint chips"?

Probably because evolutionary psychology is an incestuous pseudoscience of just-so-stories, small sample sizes, bad extrapolations, non reproducibility etc.
