The rare variants that affect IQ will generally decrease IQ – and since pleiotropy is the norm, usually they’ll be deleterious in other ways as well. Genetic load.
But, considering what is now known about the biological origins of cognition and intelligence, it is generally difficult to take claims of discrimination seriously when underrepresented groups also display relatively lower intelligence profiles. However, in this case there is no reason to think that conservatives as a group have an intellectual profile below the general population. Social conservatives tend to be a little lower in intelligence relative to liberals, but free-market conservatives (libertarians) tend to be smarter than liberals. Being very partisan, either liberal or conservative, tends to be associated with high IQ as well. Increased income levels, which are a proxy for IQ, also moves people right ideologically. In other words, there is nothing that biologically determined intelligence can do to explain the lack of conservatives, and even moderates, in the humanities….Race Hustling /r/science
