It should now be apparent that group endurance is compromised when agents seek out interaction with more random agents. If agents prefer connecting to completely different agents, our original definition of endurance no longer makes much sense. Intergroup interaction probability exceeds intragroup interaction probability from the very beginning. By definition, the group does not endure from the very first time step.

These observations can allow us to make predictions of how stable real-life minorities are. For example, minorities tend to be more stable when they hold a large store of private knowledge apart from the rest of society. In support of this, Carley notes that same-faith marriage rates for Jews in the U.S. exceed those of Catholics. One reason a religious group might be more stable than another is that it maintains a larger store of cultural knowledge separate from that of other groups.
