In other words, the conservative ideology, and especially one of its major facets—centered on a strong military, tough law enforcement, resistance to immigration, widespread availability of guns—would seem well tailored for an underlying, threat-oriented biology.
The authors go on to speculate that this ultimately reflects an evolutionary imperative. “One possibility,” they write, “is that a strong negativity bias was extremely useful in the Pleistocene,” when it would have been super-helpful in preventing you from getting killed.
All of this matters, of course, because we still operate in politics and in media as if minds can be changed by the best honed arguments, the most compelling facts. And yet if our political opponents are simply perceiving the world differently, that idea starts to crumble. Out of the rubble just might arise a better way of acting in politics that leads to less dysfunction and less gridlock…thanks to science.
IOW, conservatives operate out of fear and a herd mentality. No surprise, I know, but now it’s backed up by solid science that conservatives are deer, looking out for predators, while liberals are free spirits looking for new experiences. Kinda like tigers, but less likely to start killing other people.
