Well as the authors pointed out we have two competing hypothesis: Stereotypes are accurate or stereotypes are inaccurate. So far all the evidence suggests that they are accurate with no evidence suggesting that the are inaccurate. While the evidence we have might be wrong for various reasons, but you don’t just get to dismiss it without other evidence - gut feeling is not evidence.<p>One of the more interesting things about the paper is the evidence we have for stereotypes being accurate is the evidence for this is some of the strongest in physiological studies. Almost everything else we know has less support.<p>As for how strong does evidence have to be before you will believe you need to provide us with a p value you consider would be convincing.
