Team discourse explains media richness and anonymity effects in audit fraud cue brainstorming

This article contributes by extending media richness (MRT) and media synchronicity theories (MST) to explore how media richness and anonymity influence team interactions and success in audit fraud brainstorming. Sixty-three, three-person teams, with 189 student participants from two Universities, identified fraud risk cues in a SAS 99 audit planning case. Participants were assigned to one of three conditions: electronic anonymity (EA; n = 18 teams), electronic identified (EI; n = 28 teams), or identified face-to-face (FtF; n = 17 teams). Compared with teams in the low media richness conditions, i.e., the EA and EI, discussions in FtF teams produced more and better dialog, which resulted in better identification of fraud risk cues. Additionally, compared with the discussions in the EA teams, FtF team discussions evidenced less narcissism and were more focused and inhibited. Mediation analyses of team interactions indicated that the quantity of dialog (team production) completely explains, fully mediates, the effects of media richness and anonymity on risk assessments. Contributions include extending MRT and MST, and using automated content analysis, to explicate the role of media richness, anonymity, and team interactions in explaining audit team fraud identification success. The concluding section identifies the sample, design, and method limitations, and, discusses the potential for group support technologies to enhance or detract from audit team processes, depending on task, context, and technology.

Research highlights
► Examines the role of media richness, anonymity, and group processes in explaining fraud risk cue identification in teams.
► Discussions in face-to-face teams (i.e. high media richness) produced more dialog.
► Dialog in face-to-face teams was more descriptive and complex and surfaced more and better fraud risk cues.
► Face-to-face team discussions evidenced less narcissism and were more focused and inhibited, than in anonymous teams.
► Mediation analyses indicate that team production mediates the effects of media richness and anonymity on risk assessments.
