Crowd-sourcing a Manhunt
Can you find someone within 12 hours by mobilizing people on social media?
People often say that we live in a small world. In a brilliant experiment, legendary social psychologist Stanley Milgram proved the six degrees of separationhypothesis: that everyone is six or fewer steps away, by way of introduction, from any other person in the world. But how far are we, in time, from anyone on earth? Our team won the Tag Challenge, showing it is possible to find a person, using only his or her mug shot, within 12 hours.
In the early days of social media, this project tested the limits of the ability of social media to mobilize crowds to achieve unprecedented feats, such as crowsourcing a manhunt.
