Evidence from the behavioural sciences is increasingly used to inform and improve policy around the world across many domains. These behavioural insights can be used for a number of purposes, such as improving communication to the public, encouraging healthier behaviour, and increasing the uptake of social services that improve life outcomes. However, not all evidence can be equally applied to any policy; the strength of the evidence and suitability for the situation at hand should be assessed case by case and ideally more evidence within the new context should be established. This report presents an approach to incorporating behavioural insights into policy using a number of examples while leveraging original work on mental health, trust, and decision-making in Lebanon. The aim is not to present a specific recipe or set of recommendations, but to share general concepts and examples for consideration in establishing a behavioural policy framework.This publication is funded through the UK Research and Innovation GCRF Research for Health in Conflict (R4HCMENA); developing capability, partnerships and research in the Middle and North Africa ES/P010962/1
