The Flynn effect: a rapid increase in IQ through most of the 20th century. https://en.wikipedia.org/wiki/Flynn_effect … IQ tests are periodically renormed because of it.
The effect is extremely large - eg a 14 point gain over 66 years in Britain.
Not sure over what kind of timescales Aella is thinking here (maybe much longer than ~100 years) but Rick Nevin makes a decent case that the Flynn effect is mainly due to decreased lead exposure which is in general a pretty recent phenomenon.
