Although when I read it I came away thinking "the sociobiologists are baddies", the discussion of reductionist thinking and distinctions between genetics and biology that ran through the book, ended up priming me to be much more open minded about the subject that perhaps the authors intended. It also gave me a skepticism of psychology that turned out to be well founded as the replication crisis hit. It really set me up to be excited by systems and complexity. It certainly led to me taking classes in the philosophy of science at University and probably caused exhaustion on the part of my sociology teacher as I spent my time poking holes in methodology discussions.
I might re-read the book and Wilson's Sociobiology side by side. I remember it being very readable and less doctrinaire than a book whose introduction calls out the authors' Marxism could be expected to be. And there's clearly a lot more to Wilson than the book made out.
