INCENTIVES: The more people are exposed to socialism, the worse they behave.

In East Germany, at least, communism appears to have inculcated moral laxity.

Lars Hornuf of the University of Munich and Dan Ariely, Ximena García-Rada and Heather Mann of Duke University ran an experiment last year to test Germans’ willingness to lie for personal gain. . . .

After finishing the game, the players had to fill in a form that asked their age and the part of Germany where they had lived in different decades. The authors found that, on average, those who had East German roots cheated twice as much as those who had grown up in West Germany under capitalism. They also looked at how much time people had spent in East Germany before the fall of the Berlin Wall. The longer the participants had been exposed to socialism, the greater the likelihood that they would claim improbable numbers of high rolls.
