Exactly, the paper also expresses hopes that people continue to study of human social interaction:<p>&gt;&gt; Moving forward, experiments in artificial social contexts like ours appear to be a very powerful tool to examine strategic behavior in socially relevant situations. We hope that our work will stimulate further work along these lines.<p>It is clear it will be nearly impossible to account for all the factors in one controlled experiment. Note that such &quot;total experiments&quot; in the other scientific fields is challenging as well. Usually one first tries to understand certain fundamental processes, then they move on to the interactions between them.
