Social Media’s Affect on Teenager’s Perception of a Defendant’s Guilt or Innocence

Abstract

This study examines how TikTok influences teenagers’ perceptions of guilt and innocence in high-profile legal cases, focusing specifically on the 2022 Depp v. Heard defamation trial. As social media increasingly becomes a primary source of information for adolescents, concerns have emerged regarding the impact of short-form, emotionally driven content on legal understanding and public opinion. Using a mixed-methods case study design, this research surveyed 98 high school students from XYZ County through a media exposure questionnaire containing both quantitative and qualitative questions. Findings revealed that while TikTok content did not drastically change most participants’ opinions, it frequently reinforced preexisting beliefs through selective editing, humor, emotional framing, and personality-based portrayals. Participants often evaluated credibility based on tone, facial expressions, and viral narratives rather than legal evidence or courtroom context. The study also found that teenagers recognized the potential bias and incompleteness of TikTok content while still being influenced by it. These findings highlight the role of social media algorithms, confirmation bias, and entertainment-focused media formats in shaping adolescents’ interpretations of justice. Ultimately, the research demonstrates that TikTok’s short-form content can significantly affect how teenagers perceive legal cases, emphasizing the growing need for stronger media literacy education and critical evaluation skills among younger audiences.
