Once we accept a belief, it reshapes how we interpret what follows. We begin filtering information through it, and recognize evidence that supports it while overlooking details that contradict it. Over time, the belief is no longer an opinion; it starts feeling like the truth.
Known as confirmation bias, this is one of the most powerful catalysts of misinformation. A study by Charles G. Lord, Lee Ross and Mark R. Lepper found that individuals presented with mixed evidence on capital punishment became more entrenched in their original beliefs. Perceiving favorable evidence as more compelling and downplaying contradictory evidence, this study demonstrates how people intentionally strengthen preexisting beliefs rather than objectively evaluating new information. As such, confirmation bias makes false claims easier to accept, especially when they reflect existing suspicions.
Misinformation also flourishes in an environment with diminishing trust. When political leaders openly question or dismiss the legitimacy of the press, skepticism becomes normalized. Public confidence in traditional news sources has declined, and many no longer view established journalism as credible. For example, when President Donald Trump repeatedly labeled The New York Times as “fake news,” trust in credible journalism declined. If authority figures suggest that news organizations cannot be trusted, audiences begin to treat verified reporting and unverified claims as equally questionable.
Conspiracy theories spread because they validate distrust and offer simple answers that feel consistent with prior assumptions. According to a 2017 study by Karen M. Douglas, Robbie M. Sutton and Aleksandra Cichocka, people are more likely to endorse conspiracy theories when they feel distrust toward authorities and experience uncertainty or threat.
Another factor that accelerates the spread of misinformation is the structure of social media platforms themselves. Algorithms are designed to prioritize engagement, often am- plifying content that provokes strong emotional reactions rather than care- ful analysis. In this environment, accuracy becomes secondary to visibility. As users scroll rapidly through content, they are less likely to question sources or examine context. This constant exposure reinforces existing beliefs and creates echo chambers where misinformation circulates unchecked, further blurring the line between credible reporting and misleading claims.
A 2020 study conducted by Gordon Pennycook, Jonathon McPhetres, Yunhao Zhang, Antonio A. Rand and David G. Rand finds that people often share false news not because they believe it is accurate but because they fail to think about accuracy at the moment of sharing. The study implies that even small interventions, such as prompting users to consider whether a headline is true, can significantly reduce the sharing of false information. This demonstrates that combating misinformation may be about encouraging deliberate thinking before amplification.
Misinformation spreads through speed and inattention, while it is weakened through deliberate intake of information. The truth requires small, conscious choices from both journalists and audiences, and a willingness to pause before reacting.
