Four factors: 0. Intelligence is hard to "measure;" and even informally, there are mostly inferred attribute from a subject's performance filtered through the viewer's (fallible/biased) perception. 1. There's many domains of intelligence: - critical thinking (i.e., lawyers) - fact memory - abstract thinking - spatial - problem solving - social - political - emotional ... and far too many others to list. 2. Biases - upbringing, environment, experiences and so on tend to influence a person's preferences and beliefs, and they may be expressing what it is their social group expects or how they view themselves. 3. I'm sure there is at least one belief each of us clings to that others find wacky. Sometimes person don't pick up that a certain view is social unacceptable. Examples: - The guy in Starbucks with backpack supporting "the missile men of gaza"... de-facto endorsement of terrorism. - I happen to be vegetarian (not driving around with "meat is murder" and slaughterhouse shame pictures)... a lot of people are offended by that and heap on certain biases. - People struggling to survive, yet don't support unions, basic income or higher taxes on large trusts and estates, and are still libertarian "completely unregulated market" types.
