It this case, there can be little doubt as to the effect. The group endurance will tend to be high and the probability curves will approach each other only slowly for a minority with many facts. Using Carley's notation, we say that such a society has a complex culture.

Agent Similarity Preference and Group Endurance

Note: in order to run the simulation referred to in this slide, go here, to the Java Applet version. You will be directed to download the latest version of the Java plug-in.

Finally, we can also see what happens if agents attempt to connect to different rather than similar partners. First, try changing the slide below so that agents prefer more random partners, but still slightly similar ones, and run the simulation to see what effect this has on the minority endurance. Try it again with agents seeking totally different partners. Recall that the green curve represents the intragroup probability and the dark red curve represents the intergroup probability. Note the relative positions of these curves.
