The impact of anonymity on perceptions of source credibility and influence in computer-mediated group communication: A test of two competing hypotheses

As scholars and practitioners have endeavored to develop computer-based tools that foster effective communication and collaboration in groups, anonymity has played a key role. Anonymity purportedly minimizes status differences, liberates team members from a fear of retribution, and makes members feel more comfortable contributing to discussions. Yet these benefits may be outweighed by the impact of anonymity on receiver perceptions and behavior. Two competing hypotheses, drawn from adaptive structuration theory, were tested in this study to determine the impact of anonymity on receiver perceptions of sources and messages in computer-mediated group communication. The results of the multilevel models offer evidence in support of the discounting hypothesis and suggest that anonymity provided by electronic meeting systems may undermine source credibility and influence.
