Height-IQ-Gender interplay

If taller people indeed are more intelligent, it could be simply via larger volume
of their heads (taller people probably have larger skulls and thus larger brains).

I'd contend, though, that the difference can be alternatively explained by purely
environmental factors. Taller kids grow up to be more confident and this can
allow them to reach more of their genetic potential.

an extrinsic correlation between height and intelligence produced by Mechanisms 1 and 2....Consistent with our suggestion, we show that men may have higher IQs than women because they are taller

Maybe I am riding the short bus, but if the basic mechanism is an extrinsic correlation, why then introduce causation? Surely the statement that men are taller because they are more intelligent would be equally valid based on the stated premise. (I assume it comes out of #4, but it's unclear due to lack of comment on the number of sons intelligent parents have)
