Cheating relieves stress?
“Elevated testosterone decreases the fear of punishment while increasing sensitivity to reward. Elevated cortisol is linked to an uncomfortable state of chronic stress that can be extremely debilitating,” Josephs said. “Testosterone furnishes the courage to cheat, and elevated cortisol provides a reason to cheat.”
Additionally, participants who cheated showed lowered levels of cortisol and reported reductions in emotional distress after the test, as if cheating provided some sort of stress relief.
“The stress reduction is accompanied by a powerful stimulation of the reward centers in the brain, so these physiological psychological changes have the unfortunate consequence of reinforcing the unethical behavior,” Josephs said.
Because neither hormone without the other predicted unethical behavior, lowering levels of either hormone may prevent unethical episodes. Prior research shows that tasks that reward groups rather than individuals can eliminate the influence of testosterone on performance; and, many stress relieving techniques such as yoga, meditation and exercise reduce levels of cortisol, Josephs said.
