Biased search for information, biased interpretation of this information, and biased memory recall, have been invoked to explain four specific effects: attitude polarization (when a disagreement becomes more extreme even though the different parties are exposed to the same evidence) belief perseverance (when beliefs persist after the evidence for them is shown to be false) the irrational primacy effect (a greater reliance on information encountered early in a series) illusory correlation (when people falsely perceive an association between two events or situations).
