Episode Summary
Executive Summary: Michael Shermer interviews political scientist Timothy Redmond about political tribalism, arguing that U.S. polarization is driven less by issue divergence than by affective hatred, party sorting, media incentives, and identity fusion. They discuss structural features that lock in two-party competition, misinformation and biased perception, and practical ways to reduce tribalism through critical thinking, humility, deliberation, and better electoral rules.
Main Topics: Polarization: issue distance vs. affective hostility: Redmond distinguishes policy polarization from affective polarization, arguing that Americans often misperceive how far apart they are on issues, while dislike of the other party has genuinely increased. Why the U.S. has two parties: They trace two-party dominance to winner-take-all elections, the Electoral College, and single-member districts, which structurally disadvantage third parties and encourage duopoly politics. Identity, party sorting, and mega-identities: Redmond explains how racial, religious, and other identities increasingly align with party identity, making elections feel existential rather than merely political. Misperception, motivated reasoning, and media effects: The conversation covers hostile-media effects, selective exposure, social media amplification, and how people interpret information through partisan filters rather than neutral evaluation. Democratic reform and ranked-choice voting: Shermer and Redmond discuss ranked-choice voting, proportional representation, and Electoral College reform as possible ways to soften zero-sum politics and improve representation. Critical thinking, humility, and deliberation: Redmond argues that better citizenship requires teaching critical thinking, cultivating intellectual humility, and engaging in real cross-party deliberation rather than performative debate. Election legitimacy and democratic norms: The final section focuses on losers’ consent, winners’ magnanimity, and the danger of refusing to accept election outcomes, with an appeal to civic restraint after victories and defeats.
Key Arguments: U.S. polarization is often overstated if measured by policy positions alone; the larger shift is in how much partisans dislike each other. Party sorting can make aggregate party positions move apart even when many individuals have not changed their issue views. The two-party system is reinforced by structural rules like winner-take-all elections and the Electoral College, making third parties nearly impossible. People routinely overestimate the extremity of the opposing party and often cannot explain their own policy preferences in detail. Media ecosystems and social media intensify partisanship by rewarding outrage, selective exposure, and repeated sharing of misleading content. Real deliberation can move people toward more nuanced or even opposite positions, as shown by Fishkin-style citizen deliberation experiments. Teaching critical thinking is necessary but not sufficient; citizens also need humility, curiosity, and a disposition to yield to better arguments. Political behavior is often tribal and identity-based, so reforms must address incentives, institutions, and social habits, not just individual ignorance. Refusing election results and treating politics as permanent warfare undermines democratic self-government and magnifies social conflict.
Data Points: Affective warmth toward own party: ~70 degrees - Thermometer-scale ratings of partisan feelings in the 1970s and today; positive feelings for one’s own party stayed relatively stable. Warmth toward the other party in the 1970s: ~50 degrees - Historical baseline for how Democrats and Republicans felt about the opposing party. Warmth toward the other party today: ~30 degrees - Current negative partisanship indicates much lower affection for the opposing party. Issue-position scale example: 0 to 10 - Redmond uses a simplified left-right scale to explain how party averages can shift without individuals changing their positions. Pew polarization graph window: 1994 to 2014 - Shermer references a Pew graph showing ideological sorting over two decades. Article count in scholarly output: Over 100 articles - Redmond’s publication record mentioned in the introduction. Political science study size on conservatism and cognition: 88 papers, 22,818 subjects - Shermer cites John Jost et al.’s meta-analysis on political conservatism as motivated social cognition. Wondrium course length: 24 lectures of 30 minutes each - Promotion for The Skeptic’s Guide to American History. Electoral College states with winner-take-all: 48 of 50 states - Maine and Nebraska are the exceptions. Ranked-choice example: Alaska - Used to illustrate how ranked-choice voting can alter campaign behavior and outcomes. 2016 partisan-hatred graph: Spike around 2008 - Shermer notes Pew data showing a marked rise in partisan hatred beginning around the Obama era. Polarization measure example in surveys: 50% - Shermer notes half the voting population is near the 50/50 split, underscoring how close elections are.
Pivotal Quotes: "we don't necessarily love our own party more, we just hate the other party more" — Timothy Redmond: Explaining affective polarization versus partisan affection. "if you lose an election, You lost and you knew the rules of the game beforehand, and you have to accept that loss" — Timothy Redmond: Discussing losers’ consent and democratic legitimacy. "We need to teach critical thinking in schools... But that is not a panacea" — Timothy Redmond: Summarizing his prescription for reducing political tribalism.
Implications: Listeners should be skeptical of apparent polarization and outrage-driven media narratives, and instead support reforms and habits that reward deliberation, civic humility, and institutional fairness. The broader future of democracy depends on reducing identity warfare and strengthening losers’ consent.
