公众对许多肥胖政策的支持率很低，这是实施这些政策的一个障碍。支持率低的一个原因是人们倾向于将肥胖归咎于意志力的失败，而不是环境。相关证据支持这一立场。然而，实验证据是混合的。在两项实验研究中，参与者被随机分为两组，一组不接受任何信息，另一组是关于环境对肥胖影响的信息（研究1和2），另一组是关于环境对人类行为影响的信息（研究1）。我们调查了传达这些信息是否改变了对肥胖政策的支持和对肥胖原因的信念。参与者是从英国（研究1和2）和美国（研究2）的全国代表性样本中招募的（总计n = 4391）。研究2旨在复制现有的研究。两项研究都没有发现证据表明，传达这些信息会增加对肥胖政策的支持，或者加强对环境在肥胖中作用的信念。因此，研究2没有重复两个早期的实验研究。相反，这里报告的研究表明，人们对肥胖原因的信念是抗拒改变的证据，因此，不是一个有希望的途径，以增加对肥胖政策的支持。
Public support for numerous obesity policies is low, which is one barrier to their implementation. One reason for this low support is the tendency to ascribe obesity to failings of willpower as opposed to the environment. Correlational evidence supports this position. However, the experimental evidence is mixed. In two experimental studies, participants were randomised to receive no message, messages about the environment’s influence on obesity (Study 1 & 2), or messages about the environment’s influence on human behaviour (Study 1). We investigated whether communicating these messages changed support for obesity policies and beliefs about the causes of obesity. Participants were recruited from nationally representative samples in Great Britain (Study 1 & 2) and the USA (Study 2) (total n = 4391). Study 2 was designed to replicate existing research. Neither study found evidence that communicating the messages increased support for obesity policies or strengthened beliefs about the environment’s role in obesity. Study 2, therefore, did not replicate two earlier experimental studies. Instead, the studies reported here suggest that people’s beliefs about the causes of obesity are resistant to change in response to evidence and are, therefore, not a promising avenue to increase support for obesity policies.
