'Good Nudge Lullaby': Choice Architecture and Default Bias Reinforcement
实验发现，过去面对过更好默认选项的人，比面对随机默认选项的人更倾向于跟随默认，这反而损害了他们后来的表现，揭示了默认偏差的可塑性及其对营销和助推实践的启示。
Because people disproportionally follow defaults, both libertarian paternalists and marketers try to present options they want to promote as the default. However, setting certain defaults and thereby influencing current decisions, may also affect choices in later, similar decisions. In this article, we explore experimentally whether the default bias can be reinforced by providing good defaults. We show that people who faced better defaults in the past are more likely to follow defaults than people who faced random defaults, hurting their later performance. This malleability of the default bias explains certain marketing practices and serves as an insight for libertarian paternalists.
