Yes that is a good point. The link I gave mentions that study, and says it has failed replication attempts. I think the truth is more nuanced - there are ways it can be more effective and yes sometimes counter-effective. But that doesn't mean we should just give up fact-checking entirely. I think there are several ways we can make corrective fact checking more convincing to people and am working on building a collaborative fact-checker https://verifact.io to try to do that
