By linking data from a 40-year birth cohort study with multiple administrative databases, the authors show that 20% of the population accounts for close to 80% of economic burden. Strikingly, this group can be predicted with high accuracy from as early as 3 years old.
Every time we make a choice, we maintain an explicit representation of our confidence in that choice. Using eye-tracking and behavioural measures, the authors show that tracking decision uncertainty is helpful in guiding future behaviour.
