Consider a very simple general equilibrium 2X2 example to illustrate my point:
Divide the population into two groups: call them "men" and "women". Divide all outcomes into two groups: call them "arts" and "science". Everybody is somewhere in the 2X2 matrix.
Here are four questions we could ask of the data:
1. Why are women under-represented in science?
2. Why are women over-represented in arts?
3. Why are men over-represented in science?
4. Why are men under-represented in arts?
Think up an answer for each of those 4 questions.
