However there is accumulating evidence that heterogeneity in thought-processes may be an important determinant of individual behaviour. This paper investigates the implications of a vector-valued generalisation of the Expected Utility paradigm, which permits agents either to deliberate as per Homo-economics, or to act impulsively. That generalised decision theory is applied to explain irrational educational investment decisions, persistent social inequalities, the crowding-out effect, the pervasive influence of non-cognitive ability on socio-economic outcomes, and the dynamic relationships between non-cognitive ability, cognitive ability, and behavioural biases. These results suggest that the generalised decision theory warrants further investigation.
