This study explores the influence of observability, dependence and a combination of both, on volunteering within the Volunteer’s Dilemma (VoD). It was hypothesized that observation and dependence would increase volunteering, with the combination of both factors being the most effective in increasing volunteering. For the dependence conditions, it was further hypothesized, based on previous research, that participants would identify more with a superordinate identity, and that this would correlate with increased volunteering. However, both the observability and dependence conditions did not significantly increase volunteering behaviour, when compared to a control, whilst the observability & dependence condition had a negative correlation with volunteering. Participants also identified more with the subordinate identity, which was found to be significantly negatively correlated to volunteeringShow less
