中国在2008年遭受了一场大雪和一场大地震。为了研究灾害对风险决策的影响，通过招募受灾地区和非受灾地区的居民获得了机会样本。在大雪袭击后不久进行的一项调查（研究1）中，我们发现人们在灾难后并不总是像以前的研究所声称的那样更厌恶风险，他们倾向于接近“低概率相关收益”的选项，并避免“低概率相关损失”的选项。这些发现在汶川地震后进行的连续调查（研究2）中得到了重复。进一步发现，保险和彩票的受欢迎程度，这可能有助于过度重视小概率，被检测到已经加强了大量暴露于地震灾害。这些研究结果的风险教育和政府政策制定的影响进行了讨论。版权所有（C）2009约翰威利父子有限公司
China suffered both a heavy snow-hit and a major earthquake in 2008. To investigate the effects of disasters on risky decision making, opportunity samples were obtained by recruiting residents in both devastated and non-devastated areas. In a survey (Study 1) conducted shortly after the heavy snow-hit, we found that people were not always more risk averse after a disaster as previous studies had claimed and that they were inclined to approach an option with 'low probability associated gain' and to avoid an option with 'low probability associated loss'. These findings were replicated in a consecutive survey (Study 2) conducted after the Wenchuan earthquake. It was further found that the popularity of both insurance and lottery, which presumably contributed to overweighing of small probabilities, was detected to have been enhanced with substantial exposure to the earthquake disaster. The implications of these findings for risk education and government policy making were discussed. Copyright (C) 2009 John Wiley & Sons, Ltd.
