How much does a vote matter? | Rob Wiblin
This analysis argues that in competitive US presidential elections, the expected value of an informed vote can exceed $1.7 million due to the massive scale of federal spending and the statistical probability of single votes determining outcomes in swing states. By addressing epistemic risks where uninformed voters rely on heuristics, the text demonstrates that individuals with researched policy positions possess a significant advantage over the average voter, thereby validating the rationality of casting a ballot. Consequently, the author recommends that informed citizens prioritize voting in close contests or directing resources toward high-leverage campaigns rather than relying on passive political engagement.
