Mathematician Sam Spiro from Georgia State University explored whether it’s possible to determine the outcomes of the NCAA March Madness tournament based on friends’ bracket predictions. March Madness involves 64 college basketball teams competing in a knockout format until one champion remains. Participants fill out brackets predicting winners for each of the 63 games, but with over nine quintillion possible bracket combinations, a perfect bracket has never been achieved. Spiro’s research asks if the tournament results can be reconstructed from the scores of these brackets. If someone scores perfectly, their bracket reveals the entire tournament outcome. Conversely, a zero-score bracket indicates the opposite winners for the first round. Spiro’s interest began with a fictional presidential tournament, leading him to question how much information is needed to deduce the entire tournament’s results.
