Abstract

The research aim of the dissertation is to investigate the relationship between fake news, social networks and misinformation mechanisms, while the method of research is the literature review. It is rather clear that social networks are now part of everyday life for billions of people around the world: Through them they have fun, consume, communicate and be informed. Their existence undoubtedly has many positive effects but it is not devoid of effects in various areas of human activity. False news and misinformation in general, are one of the most important effects of the quasi domination of social networks. Misinformation in its various forms has almost always been present in human history. However, the rapid development of technology and social networks with their special features, gave another dynamic and mechanisms to misinformation and false news. One area where misinformation "thrives" is politics. In this field, with the help of computer tools such as bots and algorithms, new mechanisms of political manipulation and influence of individuals are emerging. The application of political propaganda through the mechanisms of misinformation has been applied to various top political events such as the election campaigns in the USA and France, the vote for the withdrawal of Great Britain from the European Union and the annexation of Crimea by Russia. The rapid spread of the phenomenon has led both nation states and the EU to take action against large corporations that control social networks. At the same time, on another level, tools have been developed and are constantly being developed to detect false news and misinformation mechanisms.
