Betting markets predict elections more accurately than polls
Finance
While traditional surveys rely on what people claim they will do, financial stakes force participants to discard their biases and bet on what will actually happen.
In 1984, a small experiment at the University of Iowa proved that students with twenty dollars on the line were fifteen percent more accurate at predicting elections than professional pollsters. This system, known as the Iowa Electronic Markets, pioneered the idea that financial incentives act as a filter for truth. Unlike a poll, which captures a fleeting mood or a dishonest answer, a market requires participants to back their opinions with capital. This creates a self-correcting machine where people who are wrong lose money to those who are right.
