Knowledgeable Republicans ‘less concerned’ over climate

The more Democrats think they know about global warming, the more concerned they are. But Republicans who consider themselves well informed on the topic seem no more worried than those who profess ignorance, a study suggests.

When it comes to attitudes to global warming in the US, how knowledge translates into concern depends upon people’s political views, and on whom they trust to provide information on climate change, say the political psychologists involved.

… Overall, Malka and Krosnick found that concern about global warming was greater among people who said they knew more about the subject. This was most marked for respondents who identified themselves as Democrats, and those who said they trusted scientists to provide reliable information on environmental issues.

For Republicans, and those who had little trust in scientists, more knowledge did not mean greater concern.

In part, this may reflect the different ways people get information about global warming. If your sources are the Intergovernmental Panel on Climate Change and Al Gore, Krosnick suggests, the relationship between knowledge and concern is likely to be different than if your main sources are sceptical advocacy groups such as the Heartland Institute, and the conservative radio talk-show host Rush Limbaugh.
