6 metrics that can measure the impact of fact-checking

Fact-checking too often depends on anecdotes as evidence of its impact, Alexios Mantzarlis writes, but it doesn’t have to be that way. Mantzarlis suggests six metrics that fact-checkers can use to measure the impact of their work, including measuring the amount of times a fact-check is quoted or referenced in legislative bodies, measuring the web traffic of a fact check compared to the web traffic on the original claim, and measuring the amount of times other media outlets referenced the fact-check as the final word on an issue.
