To investigate whether participants differed in their endorsement of the importance of verbal versus nonverbal strategies based on their self-reported deception ability, we conducted two between-subjects ANOVAs with deception ability (Poor, Neutral, Good) on participants’ Likert scale ratings of the importance of verbal and nonverbal strategies. Additionally, the data were examined by calculating Bayesian ANOVAs with default prior scales, using JASP software. We report the Bayesian factors [BF; see 39, 40] in line with the guidelines by Jarosz and Wiley , adjusted from Jeffreys . For ease of interpretation, BFten is used to indicate the Bayes factor as evidence in favour of the alternative hypothesis, whereas BF01 is used to indicate the Bayes factor as evidence in favour of the null hypothesis.
First, we found a significant effect of self-reported deception ability on participants’ endorsement of verbal strategies, F(2, 191) = 5.62, p = .004, ?P 2 = .056; BF10 = 7.11. Post hoc comparisons indicated that Good liars rated verbal strategies as significantly more important than Neutral liars (Mdiff = -0.82, 95% CI [-1.47, -0.18], p = .009), and Poor liars (Mdiff = -0.83, 95% CI [-1.54, -0.11], p = .018). Participants across groups did not differ with respect to their endorsement of the importance of nonverbal strategies, F(2, 191) = .003, p = .997, ?P 2 < .001; BF01 = .
Spoken and you can nonverbal steps
Next, we examined which specific verbal strategies participants reported to use when lying. We asked participants to indicate, from a list of ten options, which strategies they use. Table 2 provides an overview of the strategies endorsed by Poor, Neutral, and Good liars. Across all groups, the most frequently reported strategies were “Keeping the statement clear and simple” (endorsed by 17.6% of participants), “Telling a plausible story” (15.1% of participants), “Using avoidance/being vague about details” (13.2% of participants) and “Embedding the lie into an otherwise truthful story” (13.1% of participants). To examine differences in the endorsement of the strategies across Poor, Neutral, and Good liars we conducted a series of one-way between-subjects ANOVAs. Significant differences emerged for eight of the strategies, as follows: “Embedding the lie,” F(2, 191) = , p < .001, ?P 2 = .111; BF10 = ; “Matching the amount of details in the deceptive component of the statement to the truthful component,” F(2, 191) = 4.77, p = .010, ?P 2 = .048; BF10 = 3.32; “Matching the type of details of the deceptive component of the statement to the truthful component,” F(2, 191) = 3.56, p = .030, ?P 2 = .036; BF10 = 1.15; “Keeping the statement clear and simple,” F(2, 191) = 5.07, p = .007, ?P 2 = .050; BF10 = 4.15; “Telling a plausible story,” F(2, 191) = 5.48, p = .005, ?P 2 = .054; BF10 = 5.98; “Providing unverifiable details,” F(2, 191) = 4.95, p = .008, ?P 2 = .049; BF10 = 3.78, and “Avoidance,” F(2, 191) = 3.79, p = .024, ?P 2 = .038; BF10 = 1.43. Interestingly, Good liars reported using all of the above strategies significantly more than Poor liars (all p’s < .025). The only exception was that Poor liars reported using the avoidance strategy significantly more than Good liars (p = .026). Finally, there were no significant differences between Good, Neutral, and Poor liars in endorsing “Reporting from previous experience/memory” (F(2, 191) = 1.32, p = .268, ?P 2 = .014; BF01 = 5.96), “Using complete fabrication” (F(2, 191) = 0.57, p = .565, ?P 2 = .006; BF01 = ), and “Using other strategies” (F(2, 191) = 0.51, p = .600, ?P 2 = .005; BF01 = ). See Table 2 for the exact values and applicable post hoc comparisons.
Lie prevalence and functions
Probably the most generally cited lookup on the deception incidence quotes the fresh new frequency at on average several times per day [thirteen, 14]. More recent research, yet not, suggests that the newest delivery away from lays every day is most skewed. Many lays was told by only a handful of respected liars [15–17]. Specifically, in a study off almost step 3,100000 players, experts discovered that 5% regarding participants accounted for more 50% of the many lays stated in the last twenty four hours, while most subjects said telling no lays anyway . Numerous additional education, in addition to a reanalysis of DePaulo mais aussi al.’s the reason record studies, has actually confirmed that the majority of lies are told by a beneficial fraction men and women [14, 16]. These types of couples prolific liars will share with much more serious lays that bring tall effects when the identified . And additionally, people who notice-claimed to rest with greater regularity were more prone to cheating when you look at the laboratory jobs for personal profit . It will be easy why these prolific liars plus perceive by themselves while the significantly more competent in the deceiving and you may tell a great deal more lays which they imagine will stay unnoticed, possibly while they faith the individual does not try to find aside or they feel he’s adequate to fool the fresh receiver.
