The kinds of implications I’m thinking about are that if IQ causes X, (and if IQ is heritable) then we should not seek to change X by social engineering means, because it won’t be possible. X could be the distribution of college admittees, firemen, criminals, etc.
Not all policy has to rely on causal factors, of course. And my thinking is a little blurry on these issues in general.
