Lay incidence and attributes

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, BF_ten 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.

Verbal and nonverbal procedures

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 (M_diff = -0.82, 95% CI [-1.47, -0.18], p = .009), and Poor liars (M_diff = -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 = .

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.

The absolute most commonly quoted research toward deceit frequency prices this new regularity during the typically a few times just about every day [thirteen, 14]. Newer research, but not, signifies that the shipments off lies everyday are considerably skewed. The majority of lies try told by just a number of prolific liars [15–17]. Especially, inside a survey away from almost 3,000 participants, scientists unearthed that 5% of respondents accounted for more 50% of all the lays reported within the last day, whereas more sufferers stated advising zero lays whatsoever . Several additional training, in addition to an effective reanalysis off DePaulo et al.’s diary studies, provides verified that most lies was told through an effective minority men and women [14, 16]. This type of couple respected liars usually give much more serious lays one to bring extreme effects if thought . Together with, people who care about-stated so you can lay more often was basically more prone to cheat from inside the laboratory employment private finances . It will be possible why these respected liars together with understand on their own because more skilled within deceiving and tell a whole lot more lays that they believe will stay unnoticed, both as they trust the brand new individual will not identify out otherwise they believe he is suitable so you can deceive the brand new recipient.
