The Paradox of Reward Uncertainty: Fostering Innovation Through "Motivational Ambiguity"

Silver & Silverman’s (2022) work on reward uncertainty in prosocial behavior reveals that observers value actions more when rewards are unpredictable. This challenges the conventional wisdom that clear, predictable incentives maximize performance. I propose exploring whether strategic ambiguity in reward systems (e.g., "innovation lotteries" or probabilistic recognition) could encourage employees to pursue radical ideas without fear of failure. Unlike Michaelsen & Esch’s (2023) framework—which categorizes rewards as facilitating, boosting, or nudging—this study would test whether uncertainty itself acts as a fourth category, activating curiosity and intrinsic motivation. By comparing teams with fixed bonuses vs. probabilistic rewards, we could determine if ambiguity reduces risk aversion and increases exploratory behavior, offering a counterintuitive lever for innovation culture.
