The Effects of Group Factors on Deception Detection Performance

Abstract

Deception has been an important problem in interactive groups, impeding effective group communication and group work, yet deception detection in such a context remains understudied. Extrapolated from the interpersonal deception theory (IDT) and group composition research in cooperative contexts, this research proposes that group factors, including diversity and familiarity, have influence on the performance of deception detection. The measurement of group performance was not limited to success, as previous deception studies did, but included efficiency as well because it is fundamental to the effectiveness of deception detection. An analysis of data collected from a real-world online community found that behavioral familiarity had a positive effect, and gender diversity had a negative effect, on group success in deception detection. In addition, behavioral familiarity had a negative effect and functional diversity had a positive effect on the group efficiency of deception detection. The findings not only extend IDT in several important ways but also suggest the need to distinguish between noncooperative and cooperative groups, an important theoretical implication for group composition research.

An Exploration of Deception Detection: Are Groups More Effective Than Individuals?

“…From a research perspective, our findings open the door to the investigation of interesting questions regarding groups and their detection of deception, a door that might have been closed due to the earlier findings. These findings, added to what we know about group member ability to detect deception within the group (Fuller et al, 2012; Giordano & George, 2013; Marett & George, 2013; Zhou et al, 2013), form the basis for additional theorizing about groups and deception.…”

“…Fuller, Marett, and Twitchell (2012) found that the presence of deception had a negative impact on task performance by virtual teams, leading to lower levels of trust among group members. Zhou, Zhang, and Sung (2013) reported that behavioral familiarity helped groups detect deception; however, gender diversity in the group served as a hindrance to successful deception detection.…”

“…In a study by Zhou, Zhang, and Sung (2013), the researchers proposed that group factors, including diversity and familiarity, will influence the effectiveness of deception detection. On the basis of data collected from real-world online communities, the study concluded that familiarity of the members of a group with fellow members' behaviors positively affects the ability of the group to detect deception.…”

“…In the context of small-group decisions, it was found that different diversity measures may have different effects on the decision efficacy [35]. In particular, in CIPs, we further established the diversity hypothesis into the following before testing them separately:…”
