When Alberta announced last week it would join several U.S. states in offering the chance of life-changing prizes to citizens who get their Covid-19 vaccine, they were chasing a simple truth: For some reason, we tend to value the remote chance of a big reward far more than the certainty of a small one.

This is something that governments and companies are proving true right now as they try all sorts of things to help everyone get vaccinated and get life back to normal. And it begs the question: If it works for vaccines, what else could governments entice us to do by dangling a lottery lure? And what's happening in our brains when we do it?
