Insights from behavioural economics, which combines findings from psychology and economics, suggest that a deeper understanding of decision-making and behaviour could improve human services program design and outcomes. Principles from behavioural economics are applied to make small changes in the environment to facilitate desired behaviours. These small changes have come to be known as “nudges” which Thaler & Sunstein define as any aspect of the choice architecture that alters people’s behaviour in a predictable way without forbidding any options or significantly changing their economic incentives...Putting fruit at eye level counts as a nudge. Banning junk food does not.
