A lot of that research is just "research", or at the very least jumping to conclusions. Like finding that "women earn less than men on average", but then jumping to the erroneous conclusion that there must be discrimination against women at work. That kind of pattern is visible in almost every feminist paper. Even if the research is legitimate (for example it IS interesting that women earn less than men on average - clearly something is going on), they end up with jumping to some conclusion that they always wanted to prove to begin with.
