Politics and evo psych

Gender, specifically. Is there any significant study (ie. not pop psychology) that conflicts with the mainstream goals of gender equality? EP is likely the scientific field that I'm least familiar with.

I highly doubt there is anything in the technical literature that, by itself, conflicts with said goals. However, there is a good bit of research that is based on assumptions of '50s-style gender roles. The most notorious is, probably, the work on mating preference and parental investment. The cornerstone of this research program is David Buss' 1989 cross-cultural study. His interpretation of the results have been heavily criticized (e.g., Eagly and Wood and Buller.).
