Some Discussion on the Meaning of Endurance

Remember that this simulation is probabilistic so individual results will vary to some extent. If you were to repeate this experiment many times, you would find that the group endurance is generally higher for the two-agent minority than it is for the four-agent minority. In similar experiments Carley also found that smaller minorities have a higher group endurance.

Does this mean that larger minorities are more easily assimilated into a society than smaller minorities? This might indeed be the case, but one should note that the group endurance measure is only a single number and could mean many things.

For example, it also seems true that the interaction probability curves initially approach each other at a faster rate in the case of the smaller minority. The quick initial approach is generally followed by a long asymptotic narrowing, in which the interaction probabilities are very nearly constant. We might intuitively suppose that the probabilities are relatively stable, to remain so close to each other without crossing, for such a long time.

If the probability curves were more volatile or unstable, it would seem likely that the curves would cross earlier as a result, resulting in a shorter group endurance. Is it possible that this effect, or a similar one, is the driving force behind the larger minority's surprisingly small group endurance figure? This experiment in itself is not enough to answer this question.
