In an effort to aid policy makers seeking to change behaviour, a team of researchers summarise nine non-coercive influencers of human behaviour: the messanger (who a message comes from); incentives (such as loss avoidance); norms (what other people already do); defaults (ie, maintaining the status quo); salience (the novel and interesting); priming (acting after subconscious cues); affect (our emotions); commitments (to maintain consistent behaviour) and ego (to feel better about ourselves).
