The paper examines the impact of fake news on how individuals perceive information and make decisions. The research is based on an online questionnaire administered to a sample of respondents (N = 275) from the Republic of Moldova (Transnistria), comprising young people and adults active on social networks (77.5% females, 21.1% males and 1.5% not declaring gender). The period of data collection was from 18 February to 2 April 2026. The results highlight that frequent exposure to platforms such as Instagram, TikTok, YouTube and Telegram is associated with more frequent exposure to fake news, especially in areas such as politics, the war in Ukraine and social issues. The model used explains 36.5% of the variance in the perceived impact on individual decisions, 35.3% of the variance in the level of information verification and protection, and 15.3% of the variance in the level of emotional impact. On an emotional level, fake news mainly generates confusion, anger and stress, especially in crisis contexts. These reactions affect the capacity for critical analysis and can lead to uncertainty, information avoidance or lack of verification of sources. On a broader level, disinformation contributes to a decrease in trust in authorities and the media, accentuating social divisions and influencing group decisions through fear, panic and information manipulation. The study highlights the need to develop media literacy, critical thinking and effective fact-checking mechanisms, as well as the important role of online platforms in limiting the spread of fake news. The study provides exploratory empirical evidence on the perceived effects of fake news in the Transnistrian region, an under-researched context characterized by multiple informational influences and specific geopolitical vulnerabilities. The findings provide a contextualized perspective on the relationships between exposure to disinformation, emotional reactions, verification behaviors, and individual decision-making.
