Festinger suggested that once we’ve settled on a core belief, this ought to shape how we gather information. More specifically, we are likely to try to avoid encountering claims and information that challenge that belief, because these will create cognitive dissonance. Instead, we should go looking for information that affirms the belief. The technical (and less than ideal) term for this phenomenon is “selective exposure”: what it means is that we selectively choose to be exposed to information that is congenial to our beliefs, and to avoid “inconvenient truths” that are uncongenial to them.
