Even if people acknowledge that information is incorrect after a correction has been presented, their feelings towards the source of the original misinformation can remain unchanged. The current study investigated whether participants reduce their support of Republican and Democratic politicians when the prevalence of misinformation disseminated by the politicians appears to be high in comparison to the prevalence of their factual statements. We presented US participants either with (1) equal numbers of false and factual statements from political candidates, or (2) disproportionately more misinformation than factual statements. Participants received fact-checks as to whether items were true or false, then re-rated both their belief in the statements as well as their feelings towards the candidate. Results indicated that when corrected misinformation was presented alongside equal presentations of affirmed factual statements, participants reduced their belief in the misinformation but did not reduce their feelings towards the politician. However, if there was considerably more misinformation retracted than factual statements affirmed, feelings towards both Republican and Democratic figures were reduced – although the observed effect size was small.
