There's some research that suggest climate change and evolution denial go up (by certain measures) as the respondants understanding of the issues goes up.

The answer is apparently that the smarter you are, the more likely you are to have absorbed this information, but also, the more likely you are to realise that your social group expects you to answer in a certain way.

For people outside the social groups that have rejected evolution/climate change, more knowledge helps rather than hurts. So it's not just about ignorance.
