The success of the superforecasting project highlights the value of two decision hygiene strategies: selection (the superforecasters are, well, super) and aggregation (when they work in teams, forecasters perform better). The two strategies are broadly applicable in many judgments. Whenever possible, you should aim to combine the strategies, by constructing teams of judges (e.g., forecasters, investment professionals, recruiting officers) who are selected for being both good at what they do and complementary to one another.
