If you're trying to be more honest, then you might need to increase in vocabulary - but not the kind your grandmother would approve of.

In a three-part study of 276 adults, participants were first surveyed on their swearing habits.

Then 73,000 Facebook profiles were analysed for curse words in status updates.

They then looked at the profanity and integrity indexes across each state.
