Megastudies improve the impact of applied behavioural science.

ABSTRACT: Policy-makers are increasingly turning to behavioural science for insights about how to improve citizens' decisions and outcomes¹. Typically, different scientists test different intervention ideas in different samples using different outcomes over different time intervals². The lack of comparability of such individual investigations limits their potential to inform policy. Here, to address this limitation and accelerate the pace of discovery, we introduce the megastudy-a massive field experiment in which the effects of many different interventions are compared in the same population on the same objectively measured outcome for the same duration. In a megastudy targeting physical exercise among 61,293 members of an American fitness chain, 30 scientists from 15 differen
