We had a seminar recently from an experimental economist out of the University of Chicago. He has done a variety of cool things using field experiments. Let me mention the one he presented. The experiment involved sending people door to door to do fund raising for a (real) charity. The fundraisers (who were college students) were paid $10/hour.
Men averaged about $9/hour in donations. There was little correlation between their productivity and their appearance.
Pretty women got about $17/hour in donations.
I think Not Pretty women got something close to the guys.
The Pretty Woman effect on fund raising was entirely driven by higher donations when a man answered the door. They were more likely to contribute, although the size of the contribution was about the same.
I hereby ask ya’ll to find a plausible tie-in to Mormonism so that I can post this on T&S.
