## Introduction A recent study published in the journal Communication Research has found that sensational headlines can alter perceptions of news credibility. Researchers have demonstrated how time can influence the formation of opinions on content, and how this may have implications for media regulation. ## Methodology The research team led by Xiaoyu Zhou conducted a series of five longitudinal experiments to test the effect of sensational headlines on news credibility. Participants were 503 people who received COVID-19-related headlines, with some having sensational starters and others without. ## Results The study's results showed that sensational headlines had an immediate effect on news credibility, but this effect attenuated over time. After 54 days, participants recognized the truth of the news with greater accuracy. ## Implications Researchers concluded that sensational headlines can be used as tools to alert the public to potentially false or low-quality content. However, it is essential to note that this effect may vary depending on cultural context and individual preferences. ## Conclusion In conclusion, this study highlights the importance of more effective media regulation to ensure news credibility. It is necessary to adopt a more comprehensive approach that takes into account psychological and cultural dynamics influencing public opinion formation.
