Why are so many pretty girls insecure about their appearance?

And when you tell them that they are pretty they don't believe.
In my subjective opinion appearance matters to some extent. But if girls looks is higher than let's say 6,5/10 guys notice that she is pretty and start looking at her character and etc. So personally I see no reason for pretty girls to feel insecure. But most of the girls I know have this problem. Can you explain me why?
