Does Your Momma Need to Wash Your Mouth with Soap?

Posted .

A recent study at the University of Michigan (Psychological Science, 10/2010) confirms we have a strong desire to cleanse our mouths if we tell a lie. The study participants craved mouthwash after verbally lying. For future consideration when you feel like guzzling mouthwash: is it just bad breath or did you tell a whopper? On the other hand: do people who always tell the truth have bad breath (i.e. they have no urge to use mouthwash)? Sometimes science shows no mercy!!
