network analysis.

4. In 2003 the U.S. Army discovered Saddam Hussein hiding in a “spider hole” under a small building in his hometown, Tikrit. The army had tracked him to that location not by looking for him directly, but rather by creating a large “map” that displayed all the members of his family and tribe, showing their links to other people. Starting with just four names, the map allowed army intelligence to zero in on a small number of people whose relationships with Hussein
made it more likely that they would know where he was. The search for Saddam Hussein demonstrated the practical applications of:
a. out-groups.
b. in-groups.
c. groupthink.
d. group cohesion.
e. network analysis.
