Honestly, folks - it seems you're not as ethical as you think

Another long weekend, another personal question: how honest are you? According to the people who study these things, not as much as you think you are.

In an experiment in which people were asked to solve puzzles and were paid a set amount for each puzzle they solved, some participants were told to check their answers against an answer sheet, count the number of questions answered correctly, put their answer form through a shredder, report the number of questions they got right to the experimenter and receive the money they had earned.

A second group wasn't allowed to shred their answers before reporting how many they got right. Those whose claims about how many they got right couldn't be checked claimed to have got significantly more correct than the second group.
