There are basically only two kinds of possible causes for observed disparities in gender representation: discrimination (either active, passive, or social), or intrinsic preferences and aptitudes. Once you've established that a disparity does exist, the cause has to be one or the other.

Presuming that the cause is some sort of discrimination is equivalent to presuming that the cause isn't intrinsic differences, at least unless that presumption is rebutted.

And remember the usual posture of these situations. People establish a prima facie case that something is wrong by showing that there is a gender disparity. Then defenders of the status quo invoke "preferences" (i.e. intrinsic differences) to explain the disparity. I see no problem with requiring them to adduce evidence in support of their explanation.

So three coin flips leads to a gender disparity- I guess if you don't observe any of them, no discrimination of heads or tails could occur...
