Critically discuss Milgram’s experiment, and assess the extent to which the “small-world effect” can be found in the random Poisson network, in the Barabási-Albert “scale-free” network, and in the Watts-Strogatz “small-world” network.

Social Network Analysis – Small world Network, Scale free, random Poisson network

Description

The experiment that Stanley Milgram conducted in 1967 provided empirical evidence in favour of what is now referred to as the “small-world effect”, namely the fact that the average geodesic distance is small even for very large networks.

Critically discuss Milgram’s experiment, and assess the extent to which the “small-world effect” can be found in the random Poisson network, in the Barabási-Albert “scale-free” network, and in the Watts-Strogatz “small-world” network.
