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.
