Due to globalization and the increased availability of online collaboration tools, individuals are now likely to work together in settings where computers are their primary mode of communication. However, because communication characteristics are different in these settings, problems can arise, such as deception. Deceptive individuals may be difficult to detect over computer-based channels because many audio and visual cues to deception are filtered and communication tendencies are different. This paper presents two experiments where groups performed a collaborative task in a text-based, computer-mediated setting with and without confederate deceivers. The results show that deceivers were very successful in this setting, that groups performing a low complexity task were better at detecting deception than were groups performing a high complexity task, and that groups with members that had experience with each other had higher task performance but did not have higher deception detection accuracy than did inexperienced groups.
