Why It Might Not Be a Good Idea to Tackle Moral Issues in the Afternoon

February 03, 2014 In a series of experiments, Maryam Kouchaki of Harvard and Isaac H. Smith of the University of Utah found that people were 20% to 50% more likely to lie, cheat, or be otherwise dishonest in the afternoon than in the morning. The experience of ordinary activities over the course of the day appears to gradually deplete people’s ability to regulate themselves, an effect that’s most pronounced for those who are the most honest. Organizations might do well to be particularly vigilant in the afternoon about combating customers’ or employees’ unethical behaviors, the researchers say.
