We examine whether ambiguity aversion correlates with costume choice amongst children at Halloween. We conducted an ambiguity aversion experiment with children on Halloween during trick-or-treating and correlated this with their choice of costumes. We find that children wearing the most commonly chosen costumes are more likely to avoid a gamble with ambiguous odds. This inquiry is in line with a series of recent papers observing whether choices in simple experimental economics games correlate with theoretically similar non-laboratory behavior.
