A new study indicates men are less "ethical" than women.
Men are apparently more likely than women to feel okay about bumping up an insurance claim, or letting a work colleague take the blame for something that's not their fault.
The survey in the UK's found almost a third of men think it is acceptable not to tell a bank if they make an error in your favour.
That compares with a fifth of women.
The research, by the UK Chartered Institute for Securities and Investment, also found younger people are more likely to be comfortable with returning clothing that's been worn.
