Some dare call it conspiracy: Labeling something a conspiracy theory does not reduce belief in it.

“Conspiracy theory” is widely acknowledged to be a loaded term. Politicians use it to mock and dismiss allegations against them, while philosophers and political scientists warn that it could be used as a rhetorical weapon to pathologize dissent. In two empirical studies conducted on Amazon Mechanical Turk, I present an initial examination of whether this concern is justified. In Experiment 1, 150 participants judged a list of historical and speculative theories to be no less likely when they were labeled “conspiracy theories” than when they were labeled “ideas.” In Experiment 2 (N5802), participants who read a news article about fictitious “corruption allegations” endorsed those allegations no more than participants who saw them labeled “conspiracy theories.” The lack of an effect of the conspiracy-theory label in both experiments was unexpected and may be due to a romanticized image of conspiracy theories in popular media or a dilution of the term to include mundane speculation regarding corruption and political intrigue.
