Our intuitive psychology contributes to resistance to science. One significant bias is that children naturally see the world in terms of design and purpose. For instance, four year-olds insist that everything has a purpose, including lions ("to go in the zoo") and clouds ("for raining"), a propensity that Deborah Kelemen has dubbed "promiscuous teleology." Additionally, when asked about the origin of animals and people, children spontaneously tend to provide and to prefer creationist explanations. Just as children's intuitions about the physical world make it difficult for them to accept that the Earth is a sphere, their psychological intuitions about agency and design make it difficult for them to accept the processes of evolution. (..) In sum, the developmental data suggest that resistance to science will arise in children when scientific claims clash with early emerging, intuitive expectations. This resistance will persist through adulthood if the scientific claims are contested within a society, and will be especially strong if there is a non-scientific alternative that is rooted in common sense and championed by people who are taken as reliable and trustworthy.
