The fact that more women than men believe in things I consider 'bottom tier' beliefs - like astrology, crystals, etc. - are confusing, because women have basically the same average scores on IQ tests, right?
So there's something going on with women that doesn't impact their ability to do pattern recognition, but is impacting their ability to hold good beliefs
I bet so much of it is just socialization. Smart people have a funny way of rationalizing the nonsense they grew up with while keeping everything else in perspective.
I would think that they are not less able to hold good beliefs, but rather more inclined to hold any belief, possibly due to higher levels of openness (on average)?
