Experience can give arise to the idea that not having a good job is bad which then leads people to make negative associations between the low intelligence and not living a good life and that people who have good jobs should be liked more because they’re probably good people cause they’re more competent, ect. Another thing is that it’s less desirable to mate with someone that’s low intelligence. People also make them potential threats, same with the homeless and unattractive. It seems that once people put something into an undesirable category, it molds with all of the other negative associations, even if it’s not true. The homeless man might be a drunk so 99% of people are not going to help him just because of the association between homelessness and drugs, since when they see a homeless man they think of drugs.
