<p>How can governments persuade their citizens to act in socially beneficial ways? This ground-breaking book builds on the idea of 'light touch interventions' or 'nudges' proposed in Richard Thaler and Cass Sunstein's highly influential <i>Nudge </i>(2008). While recognising the power of this approach it argues that an alternative also needs to be considered: a 'think' strategy that calls on citizens to decide their own priorities as part of a process of civic and democratic renewal. As well as setting out these divergent approaches in theory the book provides evidence from a number of experiments to show how using 'nudge' or 'think' techniques works in practice.<br><br>Updated and rewritten this second edition features a new epilogue that reflects on recent developments in nudge theory and practice introducing a radical version of nudge 'nudge plus'. There is also a substantial prologue by Cass Sunstein.</p>
