Not all evo-psych critics are blank slate fans. Some of us just like our science to be based on repeatable experiments. The truth in evo-psych, that humans are animals that evolved in various environments, sometimes has only a tenuous connection to the claims of evo-psych. (e.g. that any particular aspect of modern life has some sort of link to some particular aspect of life on the savanna -- how could we possibly know that?)
