Lest you think only the students would lie, Naquin and team performed additional studies with managers. One hundred and seventy-seven managers played a group financial game. Participants were assigned to teams of three. Each member of the team had a chance to play the role of a manager of a project team who was allocating money for projects. They played with real money, and they were told that the amount of money that was available would be revealed after the game.

The managers who communicated via email lied more, and kept more money for themselves, compared to the managers who communicated with paper and pen.
