Episode Summary
Executive Summary: Rob Wiblin argues that voting can be one of the highest-impact uses of an hour when elections are competitive, candidates differ meaningfully, and the voter is informed enough to choose well. He quantifies both the tiny chance of swinging an election and the massive scale of government power, then weighs objections about epistemic humility and time costs before extending the analysis to campaign donations and turnout efforts.
Main Topics: Probability that one vote changes an election: Uses statistical modeling and polling data to estimate that a single vote can matter far more in close, competitive districts or tipping-point states than in safe seats. Value of changing who wins: Explains that presidential and other elections can redirect large government budgets and policy choices, making a tiny chance of influence potentially very valuable in expectation. Objections: epistemic modesty and political ignorance: Acknowledges the risk of being wrong and the low information of many voters, but argues informed voters can still have an edge and that modesty does not erase voting’s expected value. Time cost and opportunity cost of voting: Distinguishes the short act of voting from the much larger cost of researching politics, noting that for some people other high-impact uses of time may dominate. Mobilizing others: donations and get-out-the-vote: Reviews evidence that contacting friends, door-knocking, phone banking, and campaign support can generate additional votes, sometimes at modest cost per vote. Overall case for altruistic voting: Concludes that voting is often altruistically worthwhile in important, competitive elections when the voter can reasonably identify the better option.
Key Arguments: A vote rarely changes an election, but in competitive jurisdictions the probability is still meaningfully above zero and can be estimated with statistical models. Because governments control huge budgets and consequential policies, even a one-in-millions chance of affecting the outcome can yield very large expected value. The impact of voting depends not only on swing probability but also on the quality gap between candidates and the scale of issues at stake. Epistemic modesty reduces, but does not eliminate, the value of voting; voters can often know more than average due to basic research and altruistic intent. The main cost of voting is often not casting the ballot but the research needed to vote well, which can make other altruistic activities more attractive for some people. Campaign outreach can be cost-effective, especially through personal contacts, and may be a better use of resources than voting alone in some contexts.
Data Points: Florida 2000 margin: 537 votes - Would have changed the US presidential outcome from Bush to Gore. Florida 2000 margin percentage: 0.009% - Difference in Florida in the 2000 election. New Mexico 2000 margin: 366 votes - Even closer than Florida in 2000. Chance vote flips US presidential election in close state: about 1 in 1 million to 1 in 10 million - Estimated probability in competitive districts/states. Safe state tipping probability: 1 in 100 trillion - Model estimate for a very safe state like California. Small-state close-election tipping probability: as high as 1 in 3 million - Possible in places like New Mexico, Iowa, or New Hampshire in 2000. US federal spending per four years: $17.6 trillion - Used to estimate the expected value of a vote. Federal spending per American: $53,000 - Approximate share of federal spending per person over a presidential term. Federal spending per 2016 vote cast: $129 - Approximate spending associated with each cast vote in 2016. Expected influence of a 1 in 10 million vote: $1.75 million - Expected share of federal budget influenced by one vote in a swing state. Foreign aid example: $17,000 - Expected shift if policy changes from 0.5% of GDP to 0.3% with a 1 in 10 million vote-changing chance. Nuclear war willingness to pay: $1 million per US resident - Spitball estimate used to value avoiding nuclear war. Vote value via nuclear-war risk: $25,000 - Expected benefit to fellow citizens from a vote affecting nuclear-war probability. Survey on House control knowledge: 38% - Share of Americans who knew Republicans controlled the House before the 2014 election. Survey on Senate control knowledge: 38% - Share of Americans who knew Democrats controlled the Senate before the 2014 election. Survey on federal spending knowledge: 20% - Americans who knew Social Security was the biggest federal spending item. Foreign aid misconception: 33% - Share who thought foreign aid was the biggest budget item. Social Security share of federal budget: 17% - Compared against foreign aid's roughly 1%. Foreign aid share of federal budget: 1% - Used to illustrate public ignorance about spending priorities. PEPFAR impact: several million deaths prevented - Example of a policy choice with very large humanitarian consequences. Personal appeal vs stranger: 10x or greater - Friends and family appeals are much more effective than stranger appeals. Cost per vote by campaigns: $30 to $100 - Suggested cost per additional vote for some effective door-knocking/phone-banking methods. TV ad cost per vote: $100 to $1,000 - 2020 paper estimate for recent US presidential elections. Biden/Trump allied campaign funds per voter in tipping states: about $30 - Potential spending per voter in 2020 competitive states. Biden primary spending per voter: about $3 - Through Super Tuesday in the 2020 Democratic primaries. UK and Australia campaign funding per voter in marginal seats: about $10 - Compared with US funding levels. Contact from someone known: 10 percentage points - One experiment suggested this could raise turnout by that amount.
Pivotal Quotes: "the hour that you spend voting is likely to be the most impactful one of your entire year" — Rob Wiblin: Conclusion about altruistic voting in competitive elections with meaningful policy differences. "if you already follow politics well enough to vote wisely, and you'd be voting in a close election, it will usually make sense to vote" — Rob Wiblin: Rule-of-thumb guidance on when voting is worthwhile. "we shouldn't make the perfect the enemy of the good" — Rob Wiblin: Advice that informed but imperfect voting can still be valuable.
Implications: Listeners should treat voting as potentially high-impact when elections are close and stakes are large, but also weigh the research time and opportunity costs. For campaigns, personal outreach and targeting appear especially valuable.
