Are they sloppy or just crazy?

I’m a big fan of the BBC News website (and go to some trouble to get to the Domestic version—and not just because it doesn’t have ads), though every so often they run a piece that makes me (usually not literally) tilt my head and say “Huh?” With few exceptions, these stories are in the Health section. Here’s today’s example: the headline is “Humour ‘comes from Testosterone’”; a more accurate summary of the article would be “Men were ruder to unicyclist than women; researcher concludes hormones are the reason, and further fancies this has something to do with humour.”

“The idea that unicycling is intrinsically funny does not explain the findings,” said Professor Shuster.
The simplest explanation, he says, is the effect of male hormones such as testosterone.
“The difference between the men and women was absolutely remarkable and consistent,” said Professor Shuster.

Ah, the simplest explanation. The “study” appears so badly designed that I’m not convinced there are any findings, much less that hormones are the simplest explanation. Oy.
