People who didn't study physics in school tend to hold Aristotelian views or similar. Getting people to stop having Aristotelian views is one of the biggest and hardest things you do in early physics/science classes for kids, and it fails for a large number of those kids so they keep them their entire lives as they don't study more.

You wont find them among stem people like most people here on HN, but there are a lot of them out there, even in high end professions like medicine etc.
