I agree that the document blurs the line between preference/aptitude and is not totally clear which is one of the reasons overall it is a mess.

Nonetheless, many of the statements in "Personality differences", "Men's higher drive for status", and "Non-discriminatory ways to reduce the gender gap", especially the stuff about women being more prone to anxiety, liking part-time work, caring more about people than things, etc. speak strongly to aptitude for engineering, given the context of the document.

EDIT: Also, I reject the implication that the claim "women have less of a preference for engineering" is not in and of itself a harmful stereotype.
