Just call me the Feminist @bengoldacre

So, like all good geeks, I have the Bad Science book and read the sainted Dr Ben's blog regularly. I also have a slightly rusty A-level in Statistics, and a penchant for picking holes in things. So when I see bobbins like this trumpeted as proof that men are better than women, I start wondering if David Tennant's little misogynist organisation from the new St Trinian's film* is real. I'm not even linking to the Daily Fail's version, which proudly trumpets that because the study was done by a woman it must be totally gospel.

Here are the things that occurred to me when reading that news report:

1. 65 volunteers; self-selecting sample; 5% difference (not statistically significant on such a small sample). This study is not scientifically rigorous enough to prove anything.


2. who was paying for this study? The paymaster often has an influence on the conduct of the study - after all, (s)he who has the gold, makes the rules...


3. It says there were 65 volunteers. It doesn't say what the gender split was. What if only 5 of them were women?


4. How familiar were each of the volunteers with the car? An Audi A6 is a big expensive saloon. Were the male drivers more familiar with driving big saloons than the women? Were the male drivers less worried about damaging an expensive new car than the women? Could this be an explanation for their differing performance?


5. There is research shown that both men and women will play up to stereotype when under scrutiny - was some sort of control put in place to account for this?

I'm sure that there are other holes pickable. I'm also sure it's possible to pick holes in my holes. Do feel free to do so, BTW. Learning is good :)


* the new St Trinian's film is well worth seeing, by the way. It's very silly, and doesn't have as much naked Colin Firth in as the first one, but it's a lot of fun, and made me giggle lots. And it passes the Bechdel test. And it has a very feministy-yet-fun message. I approved.

True enough. But isn't prejudice ultimately about warped values rather than mistaken facts? It is easier to talk about facts, but then people tend to discount facts that don't suit their values. Being upset by reality is probably a good sign.

But I fear, what with confirmation bias and everything, that so many widespread preconceptions about "average" members of one sex, race, religion or another, are as unshakeable as they are unspeakable, studies or no. So I wonder if it might be better to beat into people's heads the point that nobody is an average member of anything.
