“Dysgenic”+pressures

 It is possible that advanced civilized society is dependent on there being a sufficiently large fraction of intellectually talented individuals. Currently it seems that there is a negative correlation in some places between intellectual achievement and fertility. If such selection were to operate over a long period of time, we might evolve into a less brainy but more fertile species, //homo philoprogenitus// (“lover of many offspring”).  However, contrary to what such considerations might lead one to suspect, IQ scores have actually been increasing dramatically over the past century. This is known as the Flynn effect; see e.g. [51,52]. It’s not yet settled whether this corresponds to real gains in important intellectual functions.  []   51. Flynn, J.R. (1987).
