Do forest owners' levels of education or value profiles explain their responses to climate change? The cultural cognition thesis (CCT) has cast serious doubt on the familiar and often criticized "knowledge deficit" model, which says that laypeople are less concerned about climate change because they lack scientific knowledge. Advocates of CCT maintain that citizens with the highest degrees of scientific literacy and numeracy are not the most concerned about climate change. Rather, this is the group in which cultural polarization is greatest, and thus individuals with more limited scientific literacy and numeracy are more concerned about climate change under certain circumstances than those with higher scientific literacy and numeracy. The CCT predicts that cultural and other values will trump the positive effects of education on some forest owners' attitudes to climate change. Here, using survey data collected in 2010 from 766 private forest owners in Sweden and Germany, we provide the first evidence that perceptions of climate change risk are uncorrelated with, or sometimes positively correlated with, education level and can be explained without reference to cultural or other values. We conclude that the recent claim that advanced scientific literacy and numeracy polarizes perceptions of climate change risk is unsupported by the forest owner data. In neither of the two countries was university education found to reduce the perception of risk from climate change. Indeed in most cases university education increased the perception of risk. Even more importantly, the effect of university education was not dependent on the individuals' value profile.
森林所有者的教育水平或价值取向能解释他们对气候变化的应对方式吗?文化认知理论(CCT)对常见且常遭批评的“知识 deficit”模型提出了严重质疑,该模型认为外行人对气候变化不太关心是因为他们缺乏科学知识。CCT 的支持者认为,科学素养和算术能力最高的公民并非最关心气候变化的人。相反,这是文化两极分化最严重的群体,因此在某些情况下,科学素养和算术能力较有限的个人比科学素养和算术能力较高的人更关心气候变化。CCT 预测,文化和其他价值观将胜过教育对一些森林所有者气候变化态度的积极影响。在此,我们利用 2010 年从瑞典和德国的 766 名私有森林所有者那里收集的调查数据,首次提供证据表明,对气候变化风险的认知与教育水平不相关,或有时呈正相关,且无需参照文化或其他价值观就能得到解释。我们得出结论,森林所有者的数据不支持最近关于先进的科学素养和算术能力会使对气候变化风险的认知两极分化的说法。在这两个国家中,均未发现大学教育能降低对气候变化风险的认知。事实上,在大多数情况下,大学教育增加了对风险的认知。更重要的是,大学教育的影响并不取决于个人的价值取向。
