The asymmetric effect of narratives on prosocial behavior
通过实验室和在线实验（超过1500名被试），发现正面叙事增加亲社会行为，而负面叙事不减少甚至略微增加亲社会行为，原因在于遵循负面叙事者被视为易受影响。
We study how positive narratives (stories in favor of a prosocial action) and negative narratives (stories in favor of a selfish action) influence prosocial behavior in a series of lab and online experiments with more than 1500 subjects. We find that, both positive and negative narratives are effective at changing how actions are perceived. However, while positive narratives increase prosocial behavior, negative narratives do not move aggregate behavior and — if anything — lead to slightly more prosocial behavior. Our results indicate that this may be due to the fact that when following a negative narrative an individual is viewed as influenceable — something that appears to be undesirable. Taken together, our study suggests that positive and negative narratives are not just the flip sides of the same coin.
