The Polarization Puzzle

Ezra Klein’s “Why We’re Polarized” argues that Donald Trump’s 2016 election was the result of a deeply flawed political system that has been polarizing for years. He asserts that tribal instincts have fueled identity politics and that people now view the political opposition as an existential threat. This bestseller has earned high praise for its incisive assessment and superb research. Political polarization, according to the author, is a complex issue with deep roots in American society. In his book, the author provides a comprehensive understanding of how the US political system reached such levels of division.

The Evolution of Political Ideologies

Klein’s book sheds light on how America’s political parties solidified their identities as either conservative or liberal through historical events such as civil rights movements and party divisions. From FDR’s progressive Democrats who ignored segregation, to the split of the Democrats in 1948 and the final straw of southern Democrats with the Civil Rights Act in 1964, Klein asserts that political affiliation is more than just a vote for a candidate; it is a means of expressing identity and values.

The Perils of Identity Politics

Klein warns against the dangers of identity politics and issues-based polarization, highlighting how deeply ingrained our human propensity to form in-groups and out-groups can be. He notes how people will prioritize widening the gap between their own group and others, even if it harms their own group. Klein argues that when politics becomes a way to express personal identity, it leads to discrimination against those who hold different views. Ultimately, he raises concern that our fixation on identity within politics could threaten not only the stability of our political system but also our very survival as a society.

Identity Politics

In “Why We’re Polarized,” Ezra Klein explains how people’s political identities merge with their nonpolitical selfhoods, creating a political “mega-identity.” This makes individuals perceive a threat to their political affiliation as a threat to all their identities, leading to declining tolerance towards opposing parties. Klein reveals that people tend to go with their group’s beliefs, even if it contradicts facts or their own senses. The author emphasizes that people’s reasoning worsens when they feel their identities are threatened, and truth prevails over falsehoods only when group loyalties are not at stake.
