1. Behavioural economics provides useful insights but is not a "magic bullet" solution for changing human behaviour. Lasting change requires a holistic approach that considers psychological, social, cultural, and deliberative factors beyond just unconscious triggers.
2. An integrated approach is needed that combines insights from behavioural economics with traditional behavioural sciences. Sustainable behaviour change stems from addressing most or all influences in a "behavioural web" that includes costs/benefits, efficacy, habits, heuristics, morality, and legitimacy.
3. Both traditional research methods and newer techniques attuned to unconscious influences are important for fully understanding human behaviour. A balanced approach using diverse methods can provide insights needed for effective social policy
