Interesting article. I have to say in advance that I'm an Ockham's razor lover.
When I mentioned the fear of conservatives brains to changes it was from a scanning study looking at what parts of the brain were activated when seeing different images, words, or texts (sorry don't have the source). In them it was the amygdala who 'jumped' to that kind of stimulus.
When most of you read my appreciation message to Neven and others, a warning signal light in your brains. As has been posted before our brains react before we are conscious. I wrote the message too effusive just to point this out to you. There, what is important is the meaning, but the way it was written was more important to your brains.
The same thing applies to conservatives. If they are afraid of changes and climate change is such a big issue and so doom, the natural reaction is to reject the idea. And all the tests and surveys show that. Is also natural, for them, to try to 'kill the messenger'.
So, any approach in that direction will fail.
Our brains first feel the emotion as a reflex action and later try to justify that emotion with conscious thoughts.
I try to go to the basis, we can always complicate our thoughts arguing about angels' sex.
So, when talking about climate change, I think, we should do it trying to avoid the doom side of it and focusing in how much better our life will be without fossil fuels. (cheaper, more independent, less rubbish and dirt, ...) The science, of course, should mainly talk about facts.
Something else that shows up in iamlsd posted article is another interesting characteristic of our brain which is "cognitive dissonance" Basically our brains can't cope with contradictory beliefs, ideas, or values at the same time.
If you can not live the way you think you end up thinking the way you live.
To feel comfortable within a group of people anybody end up assuming their believes as personal. More clear in religious or politic groups.
Whenever a believe is questioned an attack is received. If you question their believes you become an enemy. Also clearly shown in the surveys.
Never forget that thinking is a very high energy consuming performance, and Nature tells us to save energy as a basic strategy for surviving. That's why brain short cuts as stereotypes work so well.
