People lie less on LinkedIn resumés than on paper

An interesting consequence of the semi-public nature of LinkedIn resumés: people are more likely to be truthful regarding the information that is likely to be of most use to potential employers, like prior work experience and responsibilities.
A recent study by researchers at Cornell University, Jamie Guillory and Jeffrey T. Hancock, randomly assigned test subjects to one of three groups, either using traditional offline resumés, private Linkedin profiles, and public LinkedIn profiles. The results suggest that the impact of publicy is to make people more truthful about verifiable work history data. However, overall, truthfulness (or deceit) held steady, but the subjects were fudging on extracurricular details, like hobbies and interests.
Perhaps there is a universal constant of lies, with the lying coefficient moving from one variable to another.
By the way, if this motivates you to clean up the details on your LinkedIn profile — that slightly bigger title than you really had Intergalactic Sprockets, or the accounting degree you might have fudged into being a computer science BS — remember to turn off activity broadcasts in your LinkedIn settings before updating your profile, so everyone doesn’t see your tweakage.
Nonetheless, employers should be more confident about the details on LinkedIn than on traditional resumés. Does anyone still use traditional paper resumés, anymore?
