Here's a really fun one -- a cute study involving an honesty box for tea or coffee in a common room. Every week the researchers tacked up a new price list above the bax. The prices didn't change, but the picture at the top did. Faces or flowers -- and whatever the face, the eyes stared straight at you. And you know what happened? Although it was, after all, just a picture, people were nearly 3 times more likely to pay for their drink if the picture was of eyes rather than flowers! And in a psychology department too.

And to change the subject completely, the Guardian reports on a comprehensive new study that claims that there is no advantage in a single-sex education -- that the only reason that single-sex schools seem to do so well in league tables, is that they are generally independent schools with pupils from advantaged backgrounds.
