I don't think abstract thinkers are more prone to stupidity.
Sheesh, physics is all about proving abstract concepts, umm, right? I mean, the higher you go in mathematics (despite what some snooty engineer may think), the more abstract your thinking must become.
As far as this poster is concerned, the opposite is true. It's rigid thinking that leads to beliefs in religion and spirits and other such nonsense. All the little wage slaves being raised in the public school system, taught revisionist history and hate, are easy pickings for those who peddle fundamentalist clap-trap.
