Insights, tools and research to advance journalism

Fact-checking research

The American Press Institute is the sponsor of several research projects that examine the effectiveness of fact-checking, best practices, and future needs. Published findings include the growth and influence of fact-checking, the amount of misinformation on Twitter, American’s common misperceptions and how to correct them, and how politicians react to fact-checking. Read API’s full studies on fact-checking below, and see our directory of the other scholars‘ fact-checking and accountability research from around the world.

A fact check is an effective tool for correcting misinformation, whether or not it employs a “rating scale.”

correcting misperceptions
Many Americans are “confident” in misperceptions, Republican and Democrat alike, but can be corrected. Misperceptions likely occur when respondents attempt to “fill in the blanks” about complex policy issues. However, presenting respondents with corrected information can substantially reduce misperceptions, even long-term.
