The author seeks to understand the functioning of the dissemination of false messages (fake news) and its impact on the individual and collective psyche from the perspective of contemporary analytical psychology. The paper considers the current Zeitgeist along with the cultural factors that created the propitious ground for increasing media dissemination from the 1990s onwards. The growing influence of analytical psychology within the sociohistorical approach is valued. The author notes the vulnerability of the individual and collective consciousness to fake news and its insertion into competent and credible conspiracy theories. Despite, on the one hand, the formal efforts of websites, digital platforms and other digital distribution agents to verify and control this dysfunctional communication and, on the other hand, the search for psychological defence measures, there still seems to be no solution in sight.
