A new study from British journal Current Biology found that men donate competitively to impress women fundraisers, NPR reports.
When researchers studied public online donation profiles from the 2014 Virgin London Marathon, they found that people donated $15 more on average after seeing other people’s donations of at least $75. But men donated an average of $42 more than previous male donors to attractive women participants. Women donors did not display the same competitive tendency toward male fundraisers.
This finding comes on the heels of a Stanford University study that found men respond more to donation requests that appeal to their sense of self-interest.
