An natural
human mechanism. Every
human has biases to some group no matter how positive or negative, major or minor, socially acceptable or not, it doesn't matter, it's still biased. Any statement with an
opinion that you could make will have some sort of bias. Remember, just because an statement is biased, doesn't mean it's wrong.
Ex 1:
Person 1: I hate ___!
Person 2: You have an bias against ___.
Ex 2:
Person 1: I
love ___!
Person 2: you have an bias for ___.
Ps:(the sentences of person 1 are biased, but this doesn't mean they're wrong)
