We examine the effectiveness of specific nudges in the choice environment to foster healthy choice and consumption among consumers with fast vs. slow life history strategies (LHS)––short-term, impulsive, reward-sensitive (fast) vs. long-term, reflective, controlled (slow) foci––associated with low and high socio-economic status (SES), respectively. The results of two experiments, conducted in a field and an online setting, show that consumers with a fast, rather than slow, life-history strategy are more susceptible to scarcity cues, boosting choice and actual consumption of healthy foods when these cues are associated with the healthy option. Conversely, for slow LHS consumers, the evidence suggests that scarcity cues are less influential, and instead abundance cues tend to foster healthy choice. Finally, in line with the LHS logic, acute food craving mediates the impact of scarcity vs. abundance cues for fast, but not slow, strategists, while perceptions of socially validated trust in the food source fulfill this role for slow, but not fast, strategists.

促进健康：稀缺线索促进了快速而非缓慢的战略家的健康消费（而丰富线索则相反）

我们通过快速与慢速生活史策略 (LHS)——短期、冲动、奖励敏感（快速）与长期、反思性、受控（缓慢）焦点——分别与低和高社会经济地位 (SES) 相关。在实地和在线环境中进行的两项实验的结果表明，拥有快速而不是缓慢的生活史策略的消费者更容易受到稀缺线索的影响，当这些线索相关时，会促进健康食品的选择和实际消费与健康的选择。相反，对于缓慢的 LHS 消费者，证据表明稀缺性线索的影响较小，相反，丰富性线索倾向于促进健康的选择。最后，符合LHS逻辑，
