I was going to post this as a comment on The Philosophy Factory, but it ended up being so long I thought I'd put it here instead.
Thanks to Mosilager of The Warrier's Kraal, I discovered this really crappy, crappy quiz on the BBC website that 'tests' whether you are male or female by giving you a bunch of IQ test-type tasks and seeing whether you do better in the language-y ones or the math-y ones. (It also doesn't seem to distinguish between sex and gender, and don't even get me started on their "Some scientists believe that..." intros.)
It seems that in the scoring section where they tell you the results, they not only have little spiels about how "men do better on this sort of task" or "women do better", they also keep track of the average scores for males and females based on people who have taken the quiz so far.
So for one task it said:
This task tested your ability to judge people's emotions.
Average score for men: 6.6 out of 10
Average score for women: 6.6 out of 10
What does your result suggest?
If you scored 0 - 3: Do you think you're good at judging how another person is feeling? Your score suggests this doesn't come to you quite so naturally.
If you scored 4 - 6: Your result suggests you have a balanced female-male brain and find it neither easy nor difficult to judge people's emotions.
If you scored 7 - 10: Your result suggests you are a good empathiser, sensitive to other people's emotions. Women generally fall into this category.
Let's be quite clear on this: Men and women both average 6.6 out of 10 on this task. And women 'generally' fall into the high-scoring category.
How does that work?
(And don't even get me started on the other questions. In case you are interested, though, it appears I am AWESOME at estimating angles of lines, mentally rotating 3D shapes and remembering the position of objects in a picture, but I totally suck at caring about people and guessing their emotions from pictures of their eyes. Nevertheless the test scores my brain as very slightly female because I find the masculine faces in a series of pictures of men more attractive than I do the ones that they have photoshopped to look like weird sexless alien hybrids, and the ratio of my index to ring fingers is greater than 1.)
