This chapter discusses recent studies on fMRI-based lie detection. In Minds, Brains, and Law, Dennis Patterson and I examined the scholarly literature and judicial opinions on the topic, and we discussed several empirical and conceptual issues affecting the use of such evidence in legal settings. In this chapter, I focus on two conceptual issues and examine several studies that have been published since the publication of our book. The conceptual issues concern: (1) the distinction between deception and lying, and (2) the concept of lying itself (or the criteria for what constitutes a lie). As with the array of studies that we examined previously, the more-recent studies also face serious limitations because of these issues.
