"Morning people", who are more alert early in the day, are more likely to cheat and behave unethically in the night hours, researchers say.
Psychologists found that early-rising "larks" and late-night "owls" had different levels of honesty depending on the time of day. The study found a link between ethical choices and such internal clocks.
The research examined the behaviour of almost 200 people - with the subjects taking part in problem-solving tests and games without realising that it was their honesty that was being measured.
It found a significant link between people being more likely to be honest when it fitted in with their chronotype, This meant that the early-rising "larks" were more ethical in the morning - and the "owls" were more likely to be honest at night.
