The paper presents the results of a systematic review of Western academic studies on the existence of echo chambers in social media, an initial classification of the literature and the identification of research patterns. The authors show how conceptual and methodological choices influence research findings on the topic. Future research should take into account the potential shortcomings of different approaches and the significant potential of linking data.</p></abstract><trans-abstract xml:lang="ru"><p style="text-align: justify;">В исследовании приводится всесторонний обзор академической литературы по теме эхо-камер в цифровом пространстве как политического феномена, рассмотрены различные подходы, их сходства и общие различия, преимущества и недостатки, а также раскрывается консолидированная и критическая перспектива, которая, как мы надеемся, будет полезна для будущих исследований в данной области. Представлены результаты систематического обзора западных академических исследований о существовании эхо-камер в социальных медиа, первоначальная классификация литературы и выявление моделей исследований. Авторы показывают, как концептуальный и методологический выбор влияет на результаты исследований по данной теме. Будущие исследования должны учитывать потенциальные недостатки различных подходов и значительный потенциал связывания данных.</p></trans-abstract><kwd-group xml:lang="en"><kwd>echo chambers</kwd><kwd>social media</kwd><kwd>digital platforms</kwd><kwd>filter bubbles</kwd><kwd>political polarization</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>эхо-камеры</kwd><kwd>социальные медиа</kwd><kwd>цифровые платформы</kwd><kwd>пузыри фильтров</kwd><kwd>политическая поляризация</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Allcott, H., Braghieri, L., Eichmeyer, S., &amp; Gentzkow, M.
