| Abstract: | Previous research examining the accuracy of deception detection judgments by individuals has concluded that the ability to detect deception is only slightly better than chance. Research has also found that individuals tend to be over‐confident, truth‐biased, and reliant on nonverbal behavior when making veracity judgments. This study (N = 129) tested if differences in deception detection accuracy, truth‐bias, judgmental confidences, and self‐reported cue reliance exist between individual judges and groups of individuals working in collaboration. No significant differences between groups and individuals emerged for accuracy, truth‐bias, or self‐reported cue reliance. Individuals within groups, however, were significantly more confident in their decisions than individuals working alone. |
