sciencehabit writes with this interesting story about using prediction markets to weed out false positives in scientific experiments. From the article: "Gambling is frowned upon in many circles. But what if the gamblers are researchers betting on how each other's experiments will turn out, and the results are used to improve science itself? A group of psychologists has found that their collective gambling—with real money—predicted the outcome of attempts at replicating experimental results better than their own expert guesses. They propose that this type of gambling setup, known as a prediction market, could become part of how science gets done."
