Preference,Expectations, and Attributional Bias: Two Field Studies1

Two quasi-experiments were conducted to test the relationship among a perceiver's preference, expectations, and causal attributions for an event, when the outcome of the event ran for and counter to expectation and preference. Following the 1976 Superbowl, fans of Dallas and Pittsburgh and fans with no preference were asked to attribute causality for a series of game events, counterbalanced for (un)favorability for each team. Following the 1976 Presidential election, fans of Carter and Ford were asked to attribute causality for the election outcome and estimate its repeatability and mutability. Both studies revealed that fans exhibit a biased attributional pattern, offering more credit to their own side for their successes than to the opponents for their successes. Furthermore, fans see their side's successes as replicable and their side's failures as nonreplicable. The implications of the data patterns for real world manifestations of attributional bias are discussed.
