Childhood Origins of Adult Resistance to Science
Resistance to certain scientific ideas derives in large part from assumptions and biases that can be demonstrated experimentally in young children and that may persist into adulthood. In particular, both adults and children resist acquiring scientific information that clashes with common-sense intuitions about the physical and psychological domains. Additionally, when learning information from other people, both adults and children are sensitive to the trustworthiness of the source of that information. Resistance to science, then, is particularly exaggerated in societies where nonscientific ideologies have the advantages of being both grounded in common sense and transmitted by trustworthy sources.
The article discusses some interesting research into how receptive people are to ideas as children and adults (using some experiments I hadn't heard of before), how we learn, and how we evaluate information. It's pretty good, I recommend reading it if you can.
