Effect of Agent Preferences

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.

We can now ask what happens when we change certain parameters in the society. How do particular parameters affect the rise of cultural homogeneity and the time to reach perfect stability?

Firstly, rather than having agents choose the most similar partners, we can relax this condition and suppose that agents select partners randomly, or even that agents prefer partners that are different from them.

Below, for example, we have created a society that is comprised of two groups. Agents 0 through 3 share a large amount of knowledge, as do agents 4 through 7. In one experiment, we observed the cultural homogeneity curves of this society under the fully similar setting and the fully different setting to see how they compared. You can try to do this yourself using the model below. Use the slide to set the agent preference and click "Go" to run the model and graph the cultural homogeneity curve.
