“Behavioural insights”, or insights derived from the behavioural and social sciences,
including decision making, psychology, cognitive science, neuroscience, organisational
and group behaviour, are being applied by governments with the aim of making public
policies work better. As their use has become more widespread, however, questions
are being raised about their effectiveness as well as their philosophical underpinnings.
This report discusses the use and reach of behavioural insights, drawing on a comprehensive
collection of over 100 applications across the world and policy sectors, including
consumer protection, education, energy, environment, finance, health and safety, labour
market policies, public service delivery, taxes and telecommunications. It suggests
ways to ensure that this experimental approach can be successfully and sustainably
used as a public policy tool.
