Dr Halpern’s approach, carried over from his days with Mr Blair, centres on his favourite term, “Mindspace,” an acronym that stands for: Messenger (i.e. he who communicates information affects its impact); Incentives; Norms (what others do influences individuals); Defaults (pre-set options tend to be accepted); Salience (revelance and novelty attract attention); Priming (sub-conscious cues); Affect (the power of emotional associations); Commitments (keeping public promises); and Ego (the stroking of which encourage positive action).
