  But we don't. Unfortunately, people do not always revise their beliefs in light of new information. On the contrary, they often stubbornly maintain their views. Certain disagreements stay entrenched and polarized.

  Why? A common explanation is confirmation bias. This is the psychological tendency to favor information that confirms our beliefs and to disfavor information that counters them — a tendency manifested in the echo chambers and “filter bubbles” of the online world.

  If this explanation is right, then there is a relatively straightforward solution to political polarization: We need to consciously expose ourselves to evidence that challenges our beliefs to compensate for our inclination to discount it.

  But what if confirmation bias isn't the only culprit? It recently struck us that confirmation bias is often conflated with “telling people what they want to hear,” which is actually a distinct phenomenon known as desirability bias, or the tendency to credit information you want to believe. Though there is a clear difference between what you believe and what you want to believe — a pessimist may expect the worst but hope for the best — when it comes to political beliefs, they are frequently aligned.
