Then they should mention that . The Sex Pistols were a boy band too <| sep |> I agree with everything you say . If humans were rational , unbiased beings you would be absolutely right . However , I also believe that 1 although these differences do exist , they are small compared to the individual variations between individuals of the same gender . 2 It would be very difficult to use knowledge of these information in a way that ' s consistent with the data . The only thing you are justified to do is when you meet a new person , slightly adjust what you assume that person ' s characteristics are based on that person ' s gender , and then don ' t let that initial assumption prevent you from adapting to that person ' s actual characteristics as you get to know them . There is no way a human will ever purposefully adjust their behaviour in such a small and nuanced way , so anyone actually trying to use that information will end up overreacting to it and being biased . Even if this information is true and unbiased , any attempt to use it will result in biased behaviour . 3 Humans aren ' t capable of not using information they are given . We can ' t talk about differences between men and women and not have it influence our actions . And since this influence will not match reality and make us act in a biased way , then simply talking about differences between men and women makes us biased . Conclusion even if there are biological differences in the behaviour of men and women , we ' re better off leaving them to psychologists and pretending they don ' t exist . That being said , I am aware that the effect of talking about gender differences is probably minor , and isn ' t worth fighting over . If I gave my family this whole speech for such a seemingly small issue they would probably hate me , which is why I stay silent . But I ' m allergic to sexism so I still silently judge them . TLDR Even if there are differences , it ' s better if we ignore them and pretend there aren ' t .
