Can fact-checking actually change minds, or does it just reinforce our biases?
In short: We often view fact-checkers as the ultimate arbiters of truth. Yet, research suggests that while corrections can curb the spread of falsehoods, they often fail to sway deeply held political identities. The real challenge isn't just finding the truth—it is presenting it in a way that people will actually believe.
The history of fact-checking is rooted in the rise of sensationalist media during the 1850s. As the need for accuracy grew, so did the institutions designed to provide it, from the establishment of the Associated Press to the creation of Ralph Pulitzer’s Bureau of Accuracy and Fair Play in 1912. Today, the field is divided into internal checks by publishers and external checks by independent organizations like PolitiFact, FactCheck.org, and Full Fact.
The effectiveness of these efforts is a subject of intense debate. While some studies show that fact-checking can discourage politicians from spreading misinformation by increasing the reputational risks of being caught, the impact on the public is more nuanced. For instance, during the 2017 French presidential election, economists found that while fact-checking stripped Marine Le Pen's falsehoods of their persuasiveness, it did not reduce political support for her. Similarly, research into Facebook tags found that while 'disputed' labels could reduce the perceived accuracy of a headline, they could even trigger a 'backfire effect' among certain groups, making untagged articles appear more credible.
To be effective, the method of correction matters as much as the fact itself. Research suggests that simply labeling a claim as false is often insufficient. The most impactful strategies include walking through the specific reasons why a claim is incorrect, providing new and credible information that allows readers to update their knowledge, and using video, which can be more effective than text at reducing confusion. Ultimately, the most powerful tool may be 'summary fact-checking'—highlighting the total volume of a politician's false statements rather than focusing on individual claims.
