You know what gets me about the Petrie Multiplier?      Logically, it should apply to all numerical minorities in the field, not just women.  For example, Aspies.  Why then are we not complaining about autistic people being underrepresented in the field?  Surely any high school student dickish enough to tease the girls in his programming class won't spare weirdos.      Where's the statistical data to support the model?       You know how some people go "aww but she has a pretty face" even though we know it's bullshit?  Case in point.  It's like the claim "but what about my personality?"  It would be one thing if it were true, but in actuality it's just bullshit that is automatically claimed because they're fat.
