人非理性且难教化?论支持自由家长主义的证据

doi:10.3724/SP.J.1041.2019.00395

摘要/Abstract

摘要：

基于心理学的研究, 自由家长主义者认为人们的思维有个体难以克服的、根深蒂固的系统性缺陷, 并难以通过教育来避免和消除, 因此主张因势利导, 仰仗外部专家的“助推”把人们的行为引导到正确方向。然而, 从生态理性的角度看, 人们依照自由家长主义者所谓的认知偏差做出的选择未必导致糟糕的结果, 而依照自由家长主义者所推崇的理性方法做出的选择也未必导致理想的结果。本文分析了自由家长主义者用来支持助推的证据后发现：(1)它们源于一些研究者对“何为理性”的狭隘定义, 误解了人类理性的本质; (2)它们对研究结果进行了选择性的报告, 忽视了与这些证据相反的证据。通过这些分析, 我们认为“人非理性且难教化”这一自由家长主义者的论断过于武断并有失偏颇。投入教育, 教会人们如何精明老练地处理风险不仅是可行的, 而且是替代助推的一个更为持久有效的解决方案。

Abstract:

Based on research in psychology, libertine paternalists argue that our mind is systematically flawed, which leads to many cognitive biases that are too deeply entrenched to eradicate through education. Thus, they suggest that authorities should take lead and nudge people into proper behaviors and good decisions. However, from the perspectives of ecological rationality, the outcomes of the so-called cognitive biases may not be bad, and in many instances, can be even better than those of the so-called rational reasoning as suggested by libertine paternalists. We analyze the evidence libertine paternalists use to justify nudging and find two major problems: (1) some of the supposed evidence is the product of researchers’ narrow interpretations of what qualify as human rationality and rational thinking; and (2) some libertine paternalists selectively reported scientific evidence, neglecting or sparsely reporting research that show findings contradictory to their belief. We conclude that there is lack of evidence to support the assertion that people are irrational and almost impossible to educate. To invest on education and make people risk savvy not only has been shown plausible and applicable, but also should be a more sustainable solution than nudging.

Key words: nudge, ecological rationality, risk, uncertainty, heuristics, framing effect, probability learning
