If you think the average American is stupid, half the population is more stupid than the average American
I don’t think the average American is stupid, but I agree that stupid people exist in all areas of life. You can tell the average American is actually quite bright because they don’t think they know everything and respect hearing new information from different people.
It’s just that the truly stupid, biased people are so noisy that there seem to be more of them than there actually are.
