Question

What could be the reason for the prejudice/bias?

Answer 1

Answer:

person beliefs our upbringings in your culture

Explanation:

because when you are a child that's when most of your 'being aware' of stuff happens, for example: if you tell a child that red means death then the child will grow up with the belief that red means death (unless the child will be corrected in the future)

these are my personal thoughts....
