This study looked into the effects of group identity and subject content on computer-mediated group and individual decision-making. Drawing from traditional choice shift literature, it examines the concepts of choice shift and group polarization in an online setting. It focused on online decision-making and examined whether normative influence is a factor in online opinion change. In doing so it also looked at the effects of group identity as well as the effects of content on group and individual decision-making. In particular, the purpose of this research was to examine (a) the effect of normative influence on individual and group decision-making; (b) the effect of consensus on individual decision-making and; (c) if the nature of the issue being decided had an effect on group and individual decision-making. Using multilevel mixed models, findings from this study indicate that the nature of the content being discussed affected decision-making and opinion change, with there being a significant difference between intellectual issues as opposed to risk and moral issues.
