The title is sensationalist and is probably as far as most Liberals would have the concentration span to read. In the body of the text there is no proof of the titles assertion all you are able to say is that conservatives and liberals respond differently to questions after viewing certain images.
Of course that will not matter this will already be considered by lefties as absolute rock solid science which will be repeated over and over again until no-one will be allowed to dispute it’s veracity - gee wizz where has that been done before? Global Warming maybe?
I agree: however, there is proof of the bias of the "researchers":
The researchers suggest that this is in line with conservative and liberal politics whereby conservatives are focused on protection from threats, and liberals focus on a positive future.
From a nuclear apocalypse to the population bomb to global warming, liberals have been focused on an extremely negative vision of the future for my entire life.
