But you haven't even tried to make a connection between the physical differences and the social differences. You just assume that all social differences are explained biologically.
What we know for sure is that there are physical differences, and from this study we know there are mental differences.
The unknowns are how mental differences (expression of genes) are caused by environment or effect the environment.
This means we don't know whether a 50/50 split in some field is natural or a result of society railroading people into the field. It seems to me that the best way to handle policy is not to base it on unknowns, so that's why I favor policy that ensures opportunity to work in specific fields but doesn't try to balance them.
By default conservatives tend to assume that social differences are explained biologically while liberals assume they're explained culturally. Both are extreme and likely very wrong positions.
As far as gendered behavior goes, I've never seen anyone say it's strictly biologically determined with no influence at all from culture. However many people do claim the opposite (100% socially constructed with no influence at all from biology).
