Conservatives tend to score lower on empathy and have a more in-group/out-group mentality. So it is common for people to not think about different perspectives until they are personally affected. My favorite example of this is some article I read where a researcher ran small group surveys and asked people’s thoughts on trans people, and some of the responses were super specific like “trans people wear a lot of green,” or “trans people like bread.” And it was due to Jan from accounting or whatever being the only trans person they knew. So a single encounter shifts their whole perception and biases. There are a lot of people who grow up surrounded by people like them and have never had the need to see things from someone else’s perspective who is different from them.
