Behavioral Economist Dan Ariely on the Relationship Between Creativity and Dishonesty - theanke's posterous

[T]he difference between creative and less creative individuals comes into play mostly when there is ambiguity in the situation at hand and, with it, more room for justification… Put simply, the link between creativity and dishonesty seems related to the ability to tell ourselves stories about how we are doing the right thing, even when we are not.
