In contrast to previous research in the tune being played? The lens model thus decomposes judgment inaccuracy in performance e. We build objective cues to emotion and subjective use of cues to predict on and extend this work by offering a synthesis of the available emotion on the basis of the tune being played. The lens model can literature on deception judgments using the framework of the lens therefore provide both descriptive information to understand judg- model. We aim to address three main questions.
First, what cues do ment accuracy, and prescriptive information about how judgment people use when judging deception Meta-Analysis 1? For a there a lack of overlap between subjective and objective cues to thorough discussion of the lens model, see Cooksey Third, is inaccuracy mainly due to incorrect decision-making strategies or lack of valid cues to A Lens Model of Deception Judgments deception Meta-Analysis 4?
In the current article, we do not measure lie detection accuracy as percentage correct. Instead, Within the theoretical framework of probabilistic functionalism, we measure accuracy in terms of a Pearson product—moment Egon Brunswik Brunswik, ; Petrinovich, proposed a correlation coefficient—the correlation between actual deception model to understand processes of human perception.
The basic and judgments of deception. For present purposes, this correla- assumption of probabilistic functionalism is that people exist in an tional metric is superior to percentage correct. Unlike percentage uncertain environment and that judgments and inferences about the correct, it can accommodate results from the many studies of environment are therefore made on the basis of probabilistic data deception in which participants render their judgments of truthful Brunswik, , ; Hammond, Judgments of a crite- and deceptive messages on Likert scales.
The correlational metric rion are made on the basis of cues with different ecological is also necessary for the implementation of a lens model of validities, where ecological validity is the correlation between the deception judgments, as is now explained.
Also, cues differ in their use by a perceiver, where nicator, behavioral cues, and a judge see Figure 1. The commu- cue utilization can be represented by the correlation between the nicator appears at the left of the figure, and cues appear in the cue and the inference drawn by the perceiver.
Since the lens model was her deceptiveness. An earlier meta-analysis A main advantage of the lens model is its ability to model by DePaulo et al.
In the words of Karelaia and Hog- more detailed than deceptive ones. The DePaulo et al. The communicator C is displayed to the left, and the judge J is displayed to the right. Behavioral cues X appear in the middle of the figure. A previous meta-analysis by B. DePaulo et al. Generally, the accuracy of the judge i. Third, to what extent does the set of cues utilized by a perceiver to judge deception match those actually indicative of deception the matching between the left and right side of the figure?
We draw on these earlier meta-analytic data to noncorrespondence between the validity of particular deception implement the left-hand side of our lens model. In attempting to uncover deceit, detection can be statistically decomposed.
To explain the decom- judges attend to cues. From certain of those cues, they infer position, we must introduce some notation. Suppose that we have deception; from others, veracity. This process of decoding com- data on a number of potential deception cues. Suppose we enter municator behavior appears on the right-hand side of Figure 1.
Call our measure of toward that judge. Our goal is to place atop each line a utilization deceptiveness D. Again, suppose that the cue at accurate. Call this from detailed communications; in fact, the relevant r with per- correlation coefficient RDec. The similarity between this decod- of deception from our set of behavioral cues.
Let us call our measure of per- details as a judgment cue. More generally, accuracies and inac- ceived deceptiveness P. The resulting correlation, which These yielded data on the relation between deception judgments we denote RPer, reflects the predictability of deception judgments and potential judgment cues.
Meta-analysis revealed that from a set of behavioral cues. Finally, it is of interest to compare many of the cues were in fact significantly related to deception statistical predictions of deception with the corresponding predic- judgments. The strongest results indicated that judges attribute tions of perceived deception. If there was a perfect mismatch between the two sets of sistent, forthcoming communicators are judged to be truthful Mal- predictions, they would correlate —1.
More generally, a quantifi- one, From a nonquantitative analysis, Malone concluded cation of accuracy in the lens model depends on the so-called that there is some overlap and some divergence between these cues matching index—the correlation coefficient between cue-based to deception judgment and cues to actual deception.
Call this matching index G. Vrij concluded that people deception judgments by a Pearson product—moment correlation infer deception from signs of nervousness, like speech errors, coefficient—the r between judgments of deception and actual pauses, and gaze aversion. They also infer deception from odd deception. Call this accuracy correlation racc. If we can assume that behaviors, like excessive eye contact and abnormal response la- errors in predicting deception are uncorrelated with errors in tencies.
Unfortunately, his effort is unpublished, and it Thus, the accuracy of lie detection is the product of a the draws conclusions from only 69 samples of senders. To implement this lens model, we began by collecting Literature search procedures. To locate relevant studies, meta-analytic data on cues to deception judgment. These data are we conducted computer-based searches of Psychological Ab- of interest in their own right because there is no comprehensive stracts, PsycInfo, PsycLit, Communication Abstracts, Dissertation up-to-date synthesis of behavioral correlates of lie judgments in Abstracts International, WorldCat, and Google using the key- the accumulated literature.
We searched the Social Sciences Citation Index for articles that cited key references e. We do not assume that participants can accurately Criteria for inclusion of studies. Our goal was to summarize report on the bases of their deception judgments—rather, the all English-language reports of original research on cues to judg- accuracy of this reporting is a question to be empirically addressed.
To be included For the identification of objective correlates of perceived decep- in this review, a document had to report the relation between tiveness, we consider studies in which people make judgments of judgments of deception and at least one cue. To this date, a number sender was lying rather than telling the truth , the rating of a of such reviews have been conducted. Here we consider several of sender on a multipoint scale of deceptiveness, and the ratings of those reviews.
However, Zuckerman, DePaulo, and Rosenthal examined 13 stud- we did not include in this review judgments of affect, even if the ies on behaviors associated with perceived deception. These stud- affect being judged had been falsified. Although we included ies yielded data on the relation between deception judgments and studies in which children served as senders of truthful and decep- 10 distinct behaviors that might be used to form those judgments.
We treated these DePaulo In all other cases, we analyzed the reported correlation inclusion criteria. Several features of this literature deserve comment. For purposes of the current meta-analysis, the honesty-related attribute e. Senders were unit of aggregation is the sender sample. Our analyses extract one treated in one of three ways. In deception experiments, senders set of cue—judgment correlations from each independent sample of were required to lie or tell the truth on an experimenter-specified senders—aggregating across multiple groups of receivers, when topic.
In cue experiments, senders were required to exhibit or not necessary. From this literature, we extracted independent exhibit a particular behavior. In observational studies, senders sender samples.
Deception experiments, cue experiments, and observa- deception judgments to 81 different cues. Fifteen of the cues were tional studies contributed 72, 56, and 25 sender samples to the examined in only one sample of senders information about these current database, respectively. These were excluded from the Judgment cues. From these data, we abstracted 81 distinct present study.
The remaining 66 cues appear at the left of Table 1. We coded Table 1. From each report, we coded as many of the following variables as possible: a number deception from more of the cue and coded it as negative if of senders, b number of receivers, c an accuracy correlation, d perceivers inferred deception from less of the cue.
Table 1 displays at least one cue—judgment correlation, e an N for the cue— relevant results for the 66 cues that had been studied in more than judgment correlation, f the number of cue—judgment correlations, one sample. Appearing on each line of the table are an identifica- and g a multiple-cue correlation for judgments. We coded the tion number for the cue from Appendix A in an earlier review by number of senders and number of receivers from each document.
Often, the relation between the cue and perceived deception. In this case, As is indicated in the table, 41 of 66 cues that is, In light of the large number of cues be judged deceptive.
In other cases, each sender made multiple being assessed, it should also be mentioned that 27 of 66 cues have statements, and sender was the unit of analysis for the cue— a statistically significant relation to perceived deception at a more judgment correlation. In this case, a positive correlation would stringent per-cue alpha level of.
Of the 66 cues, 21 have imply that the more of a cue the sender exhibited, the more relations with perceived deception that vary significantly across deceptive she or he was judged to be.
This was Deception judgments are more strongly related to some cues either the number of statements or the number of senders. Of the 66 cues in Table 1, two have a Pearson product—moment correlation with a perceived deception that Results equals or exceeds. As these strongest cor- relations indicate, people who appear incompetent are judged to be Characteristics of the literature. We found documents deceptive, as are people whose statements do not place events that satisfied our criteria.
Of these documents, were published within their context. Eleven other cues have relations with per- and 21 were unpublished.

These documents in- objects, sound uncertain, and appear ambivalent or indifferent. In the median They are judged to be truthful if they sound immediate, if their face study, 88 receivers judged the veracity of 16 senders. Researchers reported cue—judgment correlations—that is, Pearson product— moment correlations between deception judgments and a cue to 1 We also conducted a fixed-effects meta-analysis on these data and those judgments.
In 43 cases that is, 8. ID refers to the identification number in Appendix A of B. For a further description of the cues, see that appendix. Positive entries imply that more of the cue is associated with deception or perceived deception. The six last cues in the Table were not included in the meta-analysis by B.
We were interested in any statements seem plausible, realistic, and spontaneous. We found 57 such cues. Across all the cues in Table 1, the median absolute r is. As mentioned earlier, whereas in their earlier meta-analysis DePaulo et al.
We The modest size of these correlations is, however, noteworthy. Although gaze aversion is a somewhat stronger cue to Analysis 1. For the resulting actual deception cue correlations, see deception judgments, it is still weaker than 30 of the judgment the rightmost column of Table 1. Again, these data were collected cues in Table 1. Positive correlations imply that people display more of the cue when lying than when telling the truth. From Meta-Analysis 1, we had data on a large number 2 of cues to perceived deception; in a second meta-analysis, we The entries in Table 1 are simple correlation coefficients, not standard- ized multiple regression coefficients.

Individual differences in judging deception: accuracy and bias. How to Detect Deception? In this paper we examined beliefs about deception held by legal professionals. How people really detect lies. Second, it has been suggested that lack of valid cues to deception limits accuracy. A series of 4 meta-analyses tested these hypotheses with the framework of Brunswik's lens model. Meta-Analysis 1 investigated perceived cues to deception by correlating 66 behavioral cues in samples with deception judgments.
Instead, limitations in lie detection accuracyare mainly attributable to weaknesses in behavioral cues to deception. Theresults suggest that intuitive notions about deception are more accurate thanexplicit knowledge and that lie detection is more readily improved by increasingbehavioral differences between liars and truth tellers than by informinglie-catchers of valid cues to deception.
