Recently, Brennen and Magnussen (2023, Current Directions in Psychological Science, 32, 395) reviewed several approaches to detection of deception that have been extensively researched for several decades. While this review is timely, it is overly pessimistic regarding the applicability of psychological research to criminal investigations, and at the same time seems overly optimistic on techniques that are still in their infancy. While we remain cautious in recommending the application of many tests, we argue that the potential contribution of detection tests to law enforcement is much greater than what was implied by Brennen and Magnussen (2023, Current Directions in Psychological Science, 32, 395).

The reasoning behind lie detection based on imposing cognitive load is as follows. In interview settings lying is typically more mentally taxing than truth telling (Gombos, 2006; Walczyk et al., 2013). Theoretically, interviewers could exploit this difference by imposing cognitive load. This should affect lie tellers more than truth tellers because lie tellers will have fewer cognitive resources left over than truth tellers. Asking interviewees to recall their stories in reverse order is one way of imposing cognitive load. Although we (Vrij et al., 2012) and others (Evans et al., 2013) found support for the reverse order lie detection technique, Brimbal et al. (2023) found no support. After failing to replicate our findings, Brimbal et al. (2023) conclude that there may not be sufficient evidence to train the reverse order technique in the field. We came to this conclusion in Vrij and Fisher (2016)—an article cited by Brimbal et al. (2023)—amongst other reasons because the accuracy rates obtained by imposing cognitive load lie detection techniques are quite low. Two meta-analyses supported this conclusion: 58% accuracy rate for truth tellers and 63% for lie tellers in Vrij et al. (2017) and 58.39% (total accuracy rate) in Mac Giolla and Luke (2021). In other words, we are in full agreement with Brimbal et al. (2023) about the usefulness of using reverse order recall as an imposing cognitive load lie detection technique.
