Imagine this: You're alone at work, and you're thirsty. You have no money, and you have nothing to drink. You open your office fridge and there you find six cans of Coca-Cola, and six crisp $1 bills. 

Do you take anything? Maybe a soda, or a dollar bill, to buy something for the vending machine? Do you take more than one?

Dan Ariely already has an idea what you'd do. Ariely is a professor at Duke University. He studies cheating behavior and he's run dozens of experiments on cheating: when people cheat, by how much, and why they do it.

He says that people are more likely to cheat when they're distanced from the idea of monetary value -- you're more likely to take the soda than the cash, just as you're more likely to stream a movie illegally online than to walk into a store and steal a DVD, or worse yet, take cash from the register. 

Cheating can be complicated, too, it's not all black and white. Dishonesty exists on a spectrum, and finding balance, particularly between our social behaviors and our business behaviors, is crucial, according to Ariely.
