| 英文摘要: | Unlike other politically divisive issues, the discussion about climate change does not centre on how best to take action, but on whether there is a problem in the first place. This is surprising in the face of accumulating objective scientific evidence about the reality of anthropogenic climate change and its consequences. Erin Hennes from Purdue University, USA, and co-authors tested whether system justification — the non-conscious motivation to justify current social, economic, and political arrangements — promotes polarization by biasing people to remember objective information to be more consistent with their views. Indeed, system justification motivation tends to be higher in political conservatives, who are also more likely to be climate change sceptics. The authors report that participants higher in economic system justification were more likely to misremember scientific evidence about climate change presented in a documentary as less severe. This recall bias predicted self-reported belief in climate change after watching the film in a direction that increased polarization. Because information processing can be biased due to system justification, simply providing the public with scientific evidence is not sufficient for reducing climate change scepticism. |
