Observations of a Single Group Society

When we studied the previous society, we found that perfect stability was reached somewhat faster under the different setting. This result is hard to see without conducting many runs, because the homogeneity curves are rather similar in both cases and the time to stability measure is rather volatile. What is easier to see is that the homogeneity curve rises more steeply under the different setting. For example, after 100 runs, the homogeneity after 20 time steps averaged 0.59 in the similar case, but 0.74 in the different case.

Effect of Number of Facts.

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 also ask what effect the number of facts in the society has on the model. We've created another random society. Below it is a box in which you can specify the number of types of knowledge in the society, or the number of available facts that can be learned. Press "Go" to run the simulation for 100 time steps. Try to see what happens to the cultural homogeneity with only two facts, or twenty.
