It turns out that morning people are more likely to cheat and behave unethically at night.
Researchers at Johns Hopkins University, Georgetown University and the University of Washington set out to examine the relationship between the ethical decisions people make based on whether they are early risers or night owls.
Early risers were found to be more ethical in the morning and more dishonest at night.
Night owls were found to be more honest at night and less honest during the day.
In other words, people were found to be more dishonest when they were outside of their preferred time of day.
So, the conclusion is this:
Don't trust morning people at night and don't trust night owls in the morning!
