Because people who do so often ignore that variance is non-zero. Such as your comment, which makes no mention of it and focuses on mean differences. There's a lot more to the distribution of random variables.

Just because the standard distribution of one group is slightly shifted one way or the other from the standard distribution of another group, doesn't allow you to say anything useful about the differences of individuals. Yes, there is a difference on average, but the overlap is way bigger than the difference.

- pmarreck 8y agoActually, I found evidence on my own that the overlap is bigger than the difference. Want to know the absolutely delicious irony, here? I saw it in James Damore's memo.
