By sheer accident, while researching for some material about this question, I seem to have found the article which inspired your question.
LinkIt's a very interesting article, which offers no easy answers. To sum up what I
think the various studies seem to reveal, there is some difference in the
pattern of generosity between women and men.
For example, in the "dictator game," where subjects were asked to decide how to split up ten dollars between themselves and an unknown person, women tended to be slightly more generous than men.
QUOTE
Women gave an average of $1.60 to an unknown partner; for men it was 82 cents. Forty-seven percent of the women and 60 percent of the men kept every cent for themselves.
Of course, it is important to say here that differences between
individuals are much, much more important than statistical differences between the sexes.
QUOTE
Almost no one could be called exceptionally generous – save one male who gave away the entire ten dollars.
It's interesting to note that there is no real risk in the "dictator game." Everybody gets free money. In another study where people had a choice between keeping money, or putting it into a pool which would double in value and be divided among the group, the results were quite different.
QUOTE
Men were far more trusting and cooperative. In one version of the game, they gave 94 percent of their funds to the pool; females gave 72 percent.
Overall, it appears that women tend to be a little more generous than men in "safe" giving, and that men tend to be a little more generous than women in "risky" giving. This is interesting, but perhaps not very important when it comes to daily life.
1. Both are greatly exaggerating.
2. As I have said, there is really no meaningful difference. Everybody should be encouraged to be empathetic (where women have a slight advantage) and brave (where men have a slight advantage.)
3. My personal definition of generosity is the willingness of one person to aid another person with no reasonable expectation of reward. Risk is not necessarily involved. Donating blood, for example, offers very little risk for a healthy volunteer, but it is a generous act.
