Here's a thing: “smarter people are less affected by implicit bias,” but this is wrong. Studies have shown repeatedly that intelligence does not protect from thinking biases. Intelligence is useful to overcome certain types of biases (mostly those that can be exposed with mathematical reasoning), but only once people are aware they are biased to begin with.
Being smart helps you beat biases, but does not make you any less biased to being with. If you refuse to change your position then you have a problem independent of your intelligence.
Prejudice, bigotry, racism. Think about what you're doing.
