Excerpts

“We are so locked into our political identities that there is virtually no candidate, no information, no condition, that can force us to change our minds.  We will justify almost anything or anyone so long as it helps our side, and the result is a politics devoid of guardrails, standards, persuasion, or accountability.” – Ezra Klein, Introduction: What Didn’t Happen, Page 9

 

“Society needs lots of different kinds of people, with lots of different kinds of psychologies, to thrive.  There are times when a mistrust of outsiders is necessary for a culture to repel a threat.  There are times when enthusiasm about change is the only thing standing between a society and stagnation.  Open isn’t better than closed.  Conscientious is a trait, not a compliment.  Evolutionarily, the power is in the mix of outlooks, not in any one outlook – that’s why this psychological diversity has survived.” – Ezra Klein, Chapter 2: The Dixiecrat Dilemma, Page 53

 

“I want to dwell on this for a minute, because it’s an insane finding: being better at math made partisans less likely to solve the problem correctly when solving the problem correctly meant betraying their political instincts.  People weren’t reasoning to get the right answer; they were reasoning to get the answer that they wanted to be right.” – Ezra Klein, Chapter, Page 91


Review

Is This An Overview?

There was a time in American politics that the different parties appeared to be similar.  Party affiliation was not a signifier of principles and perspectives of the individual members.  There was a want for polarization of the parties, to enable voters to differentiate the parties.  With the advent of more data about voters, the parties were able to target voters and develop ideologies that would better sort voters into the parties.  A self-reinforcing positive feedback cycle of politicians appealing to a more polarized public, which polarizes the public further.  The polarization has become so effective, that Americans have become locked into political identities.  Voters are no longer persuadable to change their mind due to candidate behavior, or policy initiatives.  Elections have become about motivating the people who already agree with party ideology, to go vote.  Supreme Court judges are chosen for party loyalty rather than merit. 

 

Polarization creates polarization, but not necessarily extremism.  People defer to group decisions because groups collectively know more than any individual, making group decisions more likely to be accurate.  People override their personal views about a policy in favor of the group’s decisions.  This has the effect of seeking to validate evidence of group’s ideas, while opposing the decisions of other groups.  Rather than seeking to have the appropriate answers, people reason to an answer that supports their group.  For partisans, an expert becomes someone credentialed that agrees with the partisan. 

 

Among the causes of problems of polarization, is the weaponization of identity.  Individuals have diverse identities, but political identities have become amplified and prominent.  Those not in the group, become treated with skepticism and hostility.  People care less about their party, but will vote for their party because of their dislike of the opposing party.  Policies that initially have bipartisan support due to merit, become partisan when a party makes the policy their own.  Society needs psychological diversity, but the parties have become psychologically homogenous.  There is less ideological overlap within the groups.

 

Caveats?

This book is focused on the system of politics, not on the individuals or groups.  The individuals and groups become simplified.  There are explanations that need to be refined, to prevent misunderstandings.  There are limits to how to manage the problems with polarization.
