Conservatives are from Mars, Liberals are from Venus. So says Chris Mooney in his new book, The Republican Brain.
I tend to agree. I’ve written as much on this blog back in 2010, and on the ABC’s Drum website again in 2011.
The thesis is that liberals and conservatives tend towards very different psychological make-ups. Political psychology studies have shown that liberals and conservatives are measurably different along a number of different axes.
For example, liberals tend to have higher scores than conservatives in Openness in personality tests. This means liberals tend to be more curious, inquisitive and exploratory when it comes to information and opinions. Conversely, conservatives tend to be less experimental, more rigid in their thinking and more dogmatic.
Liberals also tend to exhibit greater integrative complexity – which is a metric that measures the tendency to incorporate many different pieces of information into forming an attitude or making a judgement. It’s kinda ‘shades of grey’ thinking. Conservatives, on the other hand, tend towards more black and white thinking.
None of these things are rock solid. There’s no determinism at the root of this. But there are clear leanings amongst those who self-identify or vote one way or the other.
Do these psychological differences contribute to the differences of opinion among liberals and conservatives? Could they help explain why a majority of conservatives reject anthropogenic climate change, for example?
