Men are more likely to donate to attractive female charity fundraisers than unattractive ones, according to a study by two British professors. The researchers analyzed nearly 700 fundraising pages from the 2014 London Marathon website and found that pages judged more attractive by reviewers of the opposite sex received more donations. They believe this shows unconscious biological differences between men and women, and that men see donating as a way to signal wealth and generosity to potential partners. However, the author is skeptical of these conclusions and believes the professors could have figured this out without extensive research.
