Its not like the link between high intelligence and left-wing beliefs is new. Its extremely well established. IQ is a significant predictor of political beliefs. There are hundreds of studies that demonstrate and reproduce this.

The addition this study made was to control the variation for within family variation, which further confirmed the already known claim that IQ predicts political beliefs, extending it to within family variation. Effectively the same genetic markers for intelligence predict political belief. It shouldn't really be a shocking conclusion.

What about smart people falling for conspiracies and outdated beliefs, like Watson? Outliers?

Edit: downvoted for asking a question.

They didn't say it was true 100% of the time, they said there was a correlation and it and seems to be predictive.
