New US study claims those who go to bed late
and wake up early become less honest as the day goes on and are likely to cheat
in the evening.
Researcher Sunita Sah, of Georgetown
University, said: ‘They cast doubt on the stereotype that evening people are
somehow dissolute.’
The researchers from John Hopkins, Washington
and Georgetown universitys put 200 students through tests and games designed to
measure their honesty. They also asked them questions to work out whether they
were a lark or an owl.
