Brief Presentation
The current research intends to give a first assessment about the impact of virtual setting and of the Pola-rization dynamic and the potential Radicalization which may occur inside real and virtual groups. The research has planned a recruitment of a sample of 80 subjects embedded within a polarizing in-group and called upon to express their opinion about a social dilemma. The comparison between real and virtual environments shows that inside this last setting the trend to comply with the in-group is greater than in the real environment. In accordante with the literature the results obtained prove a strong presence of the Polarization phenomenon inside the virtual world but, at the same time, a great complexity of relations between the variables of interest becomes clear. Furthemore, in view of the encountered evidences, the research shows the presence of perso-nality variables which can influence the final opinion of the subjects independently from that of the in-group.
