Back in 1963, Harvard social psychologist Stanley Milgram performed an interesting experiment. Building on earlier ideas about social networks by Michael Gurevich, a PhD student at MIT, Milgram performed a number of experiments where he sent packages to randomly selected individuals. The package included instructions asking them to forward it to a particular “target person”, but with the following proviso –
If you do not know the target person on a personal basis, do not try to contact him directly. Instead, mail this folder to a personal acquaintance who is more likely than you to know the target person.
