First published as a special issue of Policy & Politics journal, this book situates reforms known as 'nudges' or 'behavioural interventions' which have emerged in public policy and administration within a broader tradition of methodological individualism.

In recent years, a wave of reforms known as 'nudges' or 'behavioural interventions' have emerged in public policy and administration. 'Nudge' policies are created to lightly influence groups in society to change their behaviour, using behavioural insights to solve complex policy problems. Generally, behavioural approaches focus on the psychology underlying the implementation and effects of policies in practice.

With contributions from international scholars, it demonstrates that when behavioural policies expand their focus beyond the individual, they have the potential to better understand, investigate and shape social outcomes.
