To Post or not to Post?: Anonymous user comments in the Israeli journalistic sphere

User comments have become an integral part of news websites. This study implements the well-validated theory of planned behavior (TPB) in order to understand the individual decision to post anonymous comments on news sites in Israel. We examine whether commenting is a spontaneous behavior, as has been argued in previous studies, or a reasoned behavior. Based on an internet survey (N=707), the present study results support the hypothesis that the process involved in posting a comment in a specific socio-political context involves a reasoned action that can be understood by applying a generic theoretical model. Empirical support for TPB model hypotheses for intention prediction was evident, with the subjective norm-intention relation stronger than the attitude and perceived behavioral control-intention relations. In spite of the anonymous nature of the comments, findings highlight the relevance of the perceived socio-political context for individuals' decision whether to post an anonymous comment.
