The rapid development of the Internet and electronic journalism has led to the formation of fundamentally new features of the information field. One of them was the feedback phenomenon: user comments, which actually supplement news material and, according to numerous studies, can have a significant impact on readers' perceptions of attitudes related to the contexts covered in the publication. This article studies the impact of user comments posted on the Internet media on the specifics of political socialization, including in the context of personal psychological characteristics. Modern approaches to studying the impact of comments on the attitudes of the media audience were analyzed, including heuristic evaluation and the impact of the “status” of a comment or its author, the concept of network trolling, including political, was also considered. The study was conducted on a sample of students using the author's questionnaire “Political socialization”, methods for measuring the level of suggestibility, group dependence, conformity, locus of control, socialization, through focus group interviews and a laboratory experiment. The results include correlations between the positive perception of comments, which is due to their high “rating” and individual psychological characteristics, including conformity, group dependence, suggestibility, social adaptation, and also trust in the political authority, the significant influence of socialization institutions and other properties studied using the methodology “Political socialization”. The focused interviews showed the negative attitude of the participants to the controversy in the comments of the Internet media, the value of pluralism, which is provided by the possibility of feedback, was noted, but opinions were expressed about the need to stop illegal actions related to hate speech and provocations in the worldwide web. The experiment conducted in three stages demonstrated that the interference of voiced opinions influences the formation of one's own ideas. Thus, in modern electronic mass media horizontal communication acts as a factor of influence on political socialization, and the intensity of this factor is largely determined by the psychological characteristics of the individual.
