An attribution analysis of opinion change viewed message persuasiveness as a function of inferred communicator biases. Recipients infer a knowledge bias (KB) by believing that a communicator's knowledge about external reality is nonveridical and a reporting bias (RB) by believing that a communicator's willingness to convey an accurate version of external reality is compromised. In an experiment with 355 undergraduates, KB expectancies were established by portraying a communicator as having a strong commitment to values represented by the probusiness or proenvironment side of a controversial issue and RB expectancies by portraying his audience as having a strong commitment to one or the other side. In all conditions, the communicator advocated the proenvironment position. Therefore, recipients' expectancies were confirmed in the context of a proenvironment communicator and/or audience and disconfirmed in the context of a probusiness communicator and/or audience. Regardless of the type of bias that Ss expected, they were more persuaded and rated the communicator as more unbiased when their expectancies were disconfirmed. Confirmation of expectancies based on RB, but not KB, was associated with inferences of communicator insincerity and manipulativeness.
