Great response.
The assertion that IQ is pseudoscience, is denying reality. While not an exact measure, it correlates with a lot of other measures of flourishing.
But higher IQ doesn’t necessarily mean happier, or better in any way.
I know some extremely (academically) intelligent people. Some are arrogant pricks, others are really pleasant, others still are really awkward and difficult to talk to outside their specific interests.
I think at this point XKCD should be a TLD.
I would join lemmy.xkcd in a heartbeat.
