Thanks, you're right. Although the rebuttal I posted addresses the memo point-by-point, it similarly fails to reach the intended audience.

Btw, maybe I'm reading this wrong, but your block quote seems to make the opposite point that you think it does. You said the research "indicates that interests are a primary driver in the discrepancy," but the quote said:

    This discrepancy between interest data and real employment
    composition indicates that there may be reasons other than
    sex differences in interests that can account for gender
    disparity in science and mathematics.
