That is the question that Joshua Greene, 35, an assistant professor of psychology at Harvard University is trying to answer. More specifically, Greene is trying to identify the particular pattern of brain activity that distinguishes people who are simply telling the truth from those who are resisting the temptation to lie. His findings, which are based on functional-magnetic-resonance-imaging (fMRI) data, shed light not only on the workings of the human mind but also on the controversy over using fMRI technology outside the lab in the detection of lies.

...improbably high number of correct answers were labeled dishonest. Most of the others were classified as honest. Researchers then averaged the fMRI data - which monitors blood flow and, therefore, activity inside the brain in real time - for each group to try to establish a neural signature that represented truth-telling and one that characterized lying.

...impossible. For one thing, the evidence for fMRI-based lie detection is still conflicted: Although past studies have associated prefrontal-cortex activity with lying, researchers have yet to reach a consensus, and Greene's latest findings suggest that activity in the prefrontal cortex may in fact represent truth-telling in some people. "There is a great deal of variation between the findings described, and, crucially, there is an absence of replication by investigators of their own findings," wrote Sean Spence, a well-respected deception researcher at the University of Sheffield, in a 2008 critique of 16 peer-reviewed articles describing...
