Since things are going so well, the researchers decided to mix things up and see how the groups respond. Suddenly, the minority group's machine started giving out five peanuts for every token. It didn't take long for the majority group to notice that they had been dealt a bad hand, and over time all of the members switched sides and joined the minority group. All except for one, who switched back to the machine he was originally trained in. Though this may, too, have been a reward maximizing strategy, as he was a low ranking member and risked having his peanuts stolen by a more dominant chimp. This way, while he may have had the inferior vending machine, he had it all to himself.
