Perceived Social Consensus Can Reduce Ideological Biases on Climate Change

摘要

It is well established that conservatives in the United States are substantially less likely than liberals to accept that climate change is happening and is human caused and are less supportive of policies to limit climate change. However, it is likely that ideological differences in climate change beliefs, attitudes, and policy preferences are smaller when people have close friends and family members who care about climate change. Here, we use nine nationally representative survey samples (total N = 16,168) to evaluate this claim and test if perceived social consensus predicts a smaller difference in climate change beliefs between liberals and conservatives. We find that social consensus plays an important role in climate change beliefs, attitudes, and policy preferences for people across the ideological spectrum, but especially among conservatives. These findings provide important insights on how to bridge ideological divides in large social dilemmas such as climate change.
