Downstream Effects of Dispositional Inferences on Confirmation Biases.

Although research has given substantial attention to understanding the antecedents of dispositional inferences, less attention has been directed at the consequences of these inferences, such that evidence linking dispositional inferences to downstream effects is relatively scarce. The present investigation examined whether dispositional inferences formed during initial observations elicited confirmatory processing of subsequent information about observed targets. Because confirmation biases influence a variety of information processing strategies, four experiments examined the extent to which dispositional inferences guided memory of new information (Experiment 1), interpretation of ambiguous information (Experiment 2), and information-seeking behavior (Experiments 3 and 4). Results indicated that biased processing of subsequent information was more likely when dispositional inferences were encouraged (i.e., impression formation objective) versus discouraged (i.e., narrative construction objective). This investigation highlights the role of causal inferences on confirmation biases and reveals the ease with which biases can be both bolstered and attenuated.
