Social search in "small-world" experiments: an analysis of the “algorithmic small-world hypothesis” (that individuals are not only connected by short paths on average but can find such short paths) finds that the median path length found is small (~6-7 steps) but the mean is large (so some individuals cannot find each other using short paths). They suggest doing new experiments to determine whether this is because individuals use different search strategies, have different motivations or beliefs, or really are far apart in the network.
