The interesting part for me was the suggestion that over time, the lower demands of school, family and workplaces can lead to lower IQ although the time frame seems pretty short to be genetically significant. My own experience (in the UK) is that younger people perhaps seem less bothered about grammar, history, philosophy (the classics?) perhaps because they have learned that all information is on the internet and have subconciously assumed therefore that they do not need to learn the application of such knowledge. When I was young I remember my schoolmates lamenting that learning maths was pointless because "calculators", maybe that is coming home to roost now.
