WE’RE MORE HONEST IN THE MORNING _ Never trust anyone after lunch. A study (Harvard and University of Utah) found people tend to be a lot more honest in the morning. In a series of experiments, people were asked to solve math problems — some of which were impossible — either in the morning or afternoon, and were told they’d be paid five cents per correct answer. They were then asked to self-report their scores. The result: Afternoon people were 20 percent to 50 percent more likely to cheat. Our self-restraint is stronger in the morning because our energy stores are higher. As our batteries drain — and this study suggests that even everyday activities drain them — we become less ethical. Another factor is sleep, which is needed to recharge our moral batteries.
