Our Evolutionary Psychology Contributes To Political Morass

TW: I suspect at some point the human brain will be sorted out and make contemporary psychology seem utterly naive and barbaric. When they do figure some things out perhaps they will be able apply some of that knowledge to our political processes.

From Nic Kristoff at NYT:
"Our political system sometimes produces such skewed results that it’s difficult not to blame bloviating politicians. But maybe the deeper problem lies in our brains.

Evidence is accumulating that the human brain systematically misjudges certain kinds of risks. In effect, evolution has programmed us to be alert for snakes and enemies with clubs, but we aren’t well prepared to respond to dangers that require forethought.

If you come across a garter snake, nearly all of your brain will light up with activity as you process the “threat.” Yet if somebody tells you that carbon emissions will eventually destroy Earth as we know it, only the small part of the brain that focuses on the future — a portion of the prefrontal cortex — will glimmer.

...Consider America’s political response to these two recent challenges:
1. President Obama proposes moving some inmates from Guantánamo Bay, Cuba, to supermax prisons from which no one has ever escaped. This is the “enemy with club” threat that we have evolved to be alert to, so Democrats and Republicans alike erupt in outrage and kill the plan.
2. The climate warms, ice sheets melt and seas rise. The House scrounges a narrow majority to pass a feeble cap-and-trade system, but Senate passage is uncertain. The issue is complex, full of trade-offs and more cerebral than visceral — and so it doesn’t activate our warning systems.

...the kinds of dangers that are most serious today — such as climate change — sneak in under the brain’s radar.

...we respond to threats that we deem disgusting or immoral — characteristics more associated with sex, betrayal or spoiled food than with atmospheric chemistry.

“That’s why people are incensed about flag burning, or about what kind of sex people have in private, even though that doesn’t really affect the rest of us,” Professor Gilbert said. “Yet where we have a real threat to our well-being, like global warming, it doesn’t ring alarm bells.”

...threats get our attention when they are imminent, while our brain circuitry is often cavalier about the future. That’s why we are so bad at saving for retirement. Economists tear their hair out at a puzzlingly irrational behavior called hyperbolic discounting: people’s preference for money now rather than much larger payments later.

...we’re far more sensitive to changes that are instantaneous than those that are gradual. We yawn at a slow melting of the glaciers, while if they shrank overnight we might take to the streets.

In short, we’re brilliantly programmed to act on the risks that confronted us in the Pleistocene Age. We’re less adept with 21st-century challenges.

The objects of our phobias, and the things that are actually dangerous to us, are almost unrelated in the modern world, but they were related in our ancient environment,” Mr. Haidt said. “We have no ‘preparedness’ to fear a gradual rise in the Earth’s temperature.”
