Stress impacts moral decision-making differently based on an individual's predisposition towards honesty or dishonesty, a study suggests. Researchers combined a stress-inducing task with a test of spontaneous cheating, revealing that stress increases dishonesty in those who are naturally inclined to be relatively dishonest. Conversely, stress leads individuals with a predisposition towards honesty to become even more honest, shedding light on the complex interplay between stress and moral behavior.
