Five Reasons Why I Am Skeptical That Indirect or Unconscious Lie Detection Is Superior to Direct Deception Detection
Abstract
The relative advantage of indirect and unconscious lie detection compared to direct detection is examined. Empirical evidence for the superiority of indirect and unconscious lie is unconvincing. Three empirical issues include comparisons of incommensurate outcomes, questionable results in control conditions, and evidence for improved performance of direct detection under some conditions. Two theoretical reasons for skepticism include consideration of the casual forces producing poor accuracy and the tendency for people to believe other people absent active cognitive processing. Generally speaking, in human lie detection, effortful and disciplined thought provides more accurate detection of lies than intuition or less than fully conscious cognitive processing.
