>>5that's not rocket science, it's one of the ways your're are personality influences your're are worldview. there are other ways: e.g. an introvert will generally not a be a grassroot leftist activist (so a leftist introvert is more likely to be either a post-modern academic or a tankie edgelord, but the more introeverted someone is the more likely he is to be either a reactionary or a libertarian or a 'post-left' anarchist), someone open to new experiences will not be a religious conservative, someone who values close relationships will be at least somewhat conservative and will use conservative-like rhetoric even when arguing for liberal or leftist causes (e.g. the whole gay marriage issue is a more conservative version of lgbtqwerty, as opposed to 'anti-assimilation' lefties) etc.
there are, of course, exceptions, but their're are just that: exceptions
