This study investigated the effect of a high- versus low-credibility sponsor on the perceived credibility of an abortion-related message. Three groups of subjects read a message that had been evaluated as "neutral" by officials of both "pro-life" and "pro-choice" groups. Sponsorship of the message was varied among the three groups (no sponsor; pro-life sponsor; pro-choice sponsor). Subjects rated the credibility of the message and credibility of the sponsor and also indicated their own attitudes toward abortion. Pro-life and pro-choice subjects did not differ in their perception of the nonsponsored message. The signature of a high-credibility sponsor improved the message's perceived credibility; however, the signature of a low-credibility sponsor did not diminish the message's credibility.
本研究调查了高可信度与低可信度的信息发布者对与堕胎相关信息的感知可信度的影响。三组受试者阅读了一条被“生命权”和“选择权”组织的官员均评定为“中立”的信息。该信息在三组中的发布者情况有所不同（无发布者；生命权发布者；选择权发布者）。受试者对信息的可信度、发布者的可信度进行了评分，并表明了自己对堕胎的态度。生命权和选择权受试者对无发布者信息的感知没有差异。高可信度发布者的署名提高了信息的感知可信度；然而，低可信度发布者的署名并未降低信息的可信度。
