Conclusions:
1. Women are resigned to having low expectations.
2. So would you if you had to deal with men all the time.

Women and men are often perceived as having differences in their senses of humour but, until now, there had been no neurological evidence for such suspicions. The new brain scanning study showed that although men and women tended to agree on which of the single-panel cartoons they were shown were funny, they processed the humour differently in their brains.
In particular, women appear to have a lower expectation that the cartoon will be funny than men. “Women appear to have less expectation of a reward, which in this case was the punch line of the cartoon. So when they got to the joke’s punch line, they were more pleased about it,” says Allan Reiss, one of the study’s authors, at Stanford University School of Medicine in California, US.
