[Purpose/significance] Affected by the backfire effect, the information of refuting rumors often fails to achieve the desired effect. From the perspective of personalization, this paper puts forward a new way to combat the backfire effect and provide a new strategy for dealing with online rumors. [Method/process] Based on the framework ef? fect of personalization and theory of cognitive resource matching hypothesis, through grouping experiments on rumor re? futing information with different degrees of personalization, this paper verifies the influence of the degree of personaliza? tion on the anecdotal information and the cognitive resources invested by the information audience in dealing with the anecdotal information. [Result/conclusion] The highly personalized degree of rumor-refuting information can signifi? cantly influence the public's original attitude toward rumors and relevant knowledge revision, so as to improve the pub? lic's trust in rumor-refuting information. The main reason for this effect is that highly personalized framings can posi? tively influence the public's cognitive resource allocation.
