How Pete Blair scored 100% in a deception detection study

In a 2014 deception detection study, Pete Blair made 33 judgments—and got all 33 right. That paper was titled “Expertise in deception detection involves actively prompting diagnostic information rather than passive behavioral observation.” I ask Pete about what the factors were in him getting 100% accuracy in that study, and we talk about the interplay between verbal and nonverbal behavior. Pete talks about the importance of context and domain knowledge in making high-confidence judgments, and he discusses how such insights will sometimes be based on aspects that we aren’t consciously aware of.
