Winners are more likely to Cheat

When people succeed in competition against others, it seems to compromise their ethics. It makes them more likely to cheat afterwards," (said Amos Schurr, a professor of psychology at Ben-Gurion University of the Negev in Israel).

The problem, he says, seems to be a very specific type of success: the kind that involves social comparison, the sort that means doing better than others, instead of just doing well. And he believes it all boils down to a sense of entitlement that beating others in sports, business, politics, or any other form of head-to-head competition seems to foster in victors.

"Dishonesty is a pretty complex phenomenon — there are all sorts of mechanisms behind it," said Schurr. "But people who win competitions feel more entitled, and that feeling of entitlement is what predicts dishonesty."

In other words, when people win against others, they tend to think they're better, or more deserving. And that thinking helps them justify cheating, since, after all, they're the rightful heir to whatever throne is next — "If I'm better than you, I might as well make sure I win, because I deserve to anyway."

The abundance-oriented approach

When you don't need to compare yourself to other people, you gravitate towards things that you instinctively enjoy doing, and you're good at, and if you just focus on that for a long enough time, then chances are very, very high that you're going to progress towards mastery anyway, and the fame and the power and the money and everything will come as a byproduct, rather than something that you chase directly in trying to be superior to other people.

If you were to go back to the three things that people need—mastery, belonging, and autonomy—I'd add a fourth, after basic necessities have been met. It’s the attitude or the worldview that you bring to life. And that worldview can be characterized, just for simplicity, in one of two fashions: One extreme is a kind of scarcity-minded approach, that my win is going to come at somebody else's loss, which makes you engage in social comparisons. And the other view is what I would call a more abundance-oriented approach, that there's room for everybody to grow.
