30 different studies conducted at the University of California at Berkeley have demonstrated that rich people exhibit unethical decision-making tendencies, ranging from being more likely to run you down with your car while driving to lying during negotiations, even cheating in a simple game of chance, just to win a $50 prize.

Researchers at the University have been studying income inequality. As a part of that research they organized and conducted 30 different experiments, using subjects from all over the United States. They employed both experimental and naturalistic methods of research, simulated lab experiments and experiments in the field.

The results were surprising, even to those conducting the research. One of the lead researchers, Paul Piff, says “We never expected to find this” when discussing the results of these varied studies, all of which showed consistent results, across the board – the people with money were more likely to act unethically, in both real and simulated experiments.
