The Verifiability Approach predicts that truth tellers will include details that can be verified by the interviewer, whereas liars will refrain from providing such details. A meta-analysis revealed that truth tellers indeed provided more verifiable details (k = 28, d = 0.49, 95% CI [0.25; 0.74], BF[subscript 10] = 93.28), and a higher proportion of verifiable details (k = 26, d = 0.49 95% CI: 0.25, 0.74, p < 0.001, BF[subscript 10] = 81.49) than liars. We found no evidence that liars would include more unverifiable details than truth tellers (k = 20, d = -0.31, 95% CI [-0.02; 0.64], BF[subscript 10] = 1.12) Moderator analysis revealed the verifiable detail effect was substantially larger when the statement is the suspect's alibi, but smaller when an incentive to appear credible was used. Our findings support the main prediction behind the Verifiability Approach, but also stress the need for larger sample sizes and independent replications.
