You need an experiment. I want to know whether these genes (X) affect intelligence (Y). Then I need some kind of exogenous variation that allows me to isolate it from other shit that affects intelligence.
I don't know which identification strategy would work best here, maybe you could look at twins? Some twins are identical, some are not, so can compare them or something.

That's how people usually jump from correlation to causation, by exploiting an exogenous variation in the explanatory variable.
