“In fact people resent those that are more intelligent..” I’ve never seen this. Unless someone is picking another apart, but thats just generally mean.
Envy, fear, contempt, ... there's a whole bunch of negative emotion directed toward the smarter ones. Or if it isn't hateful, they try to manipulate them into doing their work for them. Very little just plain ol' accepance of them.
If you're lucky you'll get the sapiophiles.
Maybe you haven't been around people who aren't intelligent. Or maybe you aren't. But when there is a divide in intelligence it is rarely good.
