Theory and research of disinformation in contemporary media studies
Steinwald, Robert ; Podzimek, Jan (advisor) ; Miessler, Jan (referee)
Disinformation is an important topic, which is currently receiving considerable attention not only in academic circles, but also in the public sphere. The reason is their potentially strong and unpredictable influence. Despite the importance of this topic, we find that the very concept of "disinformation" is not entirely stable and its meaning may vary according to individual authors or approaches. However, it is not only the meaning in terms of definition, but also the properties and internal structure and the relationship to related concepts such as fake news, hoaxes, misinformation, etc. And it is the mapping of various concepts of disinformation that will be the research goal of this bachelor thesis. The material will be theoretically focused professional publications on the topic from various authors. However, the concept of misinformation will not only be examined on a semantic level, but also in relation to the social environment and events, including the relationship to media legislation, regulation and literacy, as well as to certain topics in connection with which a number of misinformations are spreading (eg covid- 19). This will be taken into account in several studies and reports focused on misinformation in today's society.

Archetypal narrativisation and it's use in disinformations
Lebduška, Daniel ; Nečas, Vlastimil (advisor) ; Soukup, Martin (referee)
The aim of the diploma thesis Archetypal narrativisation and it's use in disinformations is to verify the connection between archetypal narrativization and misinformation, to describe which archetypal narratives are most often used by misinformation, to systematize them and then to describe which emotions are targeted by archetypal narrativization in misinformation. This study therefore explores the use of archetypal narrativization as a persuasion technique in disinformation campaigns. Drawing on the concept of archetypes from Jungian psychology and narrativization theory, this research examines how archetypal elements are strategically used to shape and disseminate misinformation. Through a comprehensive literature review and analysis of specific misinformation messages, the study examines the underlying motivations and effects of the use of archetypes in misinformation narratives. By exploiting deeply embedded psychological patterns and collective cultural symbolism, these campaigns seek to manipulate emotions, promote cognitive biases, and exploit social contradictions. The use of archetypes such as hero, villain, and victim allows purveyors of disinformation messages to create compelling narratives that resonate with target audiences and elicit specific responses. The thesis proposing further...
