Now we may finally understand why we just “can’t all get along.” A new study reveals our brains are literally in the way.
Most people like to think of themselves as open-minded and rational, but a new study reveals that the brain is neurologically hard-wired to defend political beliefs &ndash, and feels severely threatened when opposed.
In a new USC-led study, neuroscientists have determined that when people’s political beliefs are challenged, our brains respond in a similar manner to personal threats. Basically, it cues the “ fight or flight” survival instinct: the brain’s areas involved in personal identity and emotion senses activate in a similar manner to an attack on a deeply personal and emotional level.
Consequently, that person may shut down, disregarding any rational evidence that is contrary to their beliefs. Political beliefs are often so entrenched that they become unmovable, or as lead author of the study Jonas Kaplan puts it, “to consider an alternative view, you would have to consider an alternative version of yourself.”
As the study’s authors note, this shutdown of dialogue poses a serious problem for our shared future.
“The inability to change another person’s mind through evidence and argument, or to have one’s own mind changed in turn, stands out as a problem of great societal importance,” the researchers wrote. “ Both human knowledge and human cooperation depend upon such feats of cognitive and emotional flexibility.”
Understanding the root causes of the growing hyper-partisanship in the U.S. is the first step towards a more conscientious, participatory, and effective political discourse. In order to combat a predilection towards bickering and misunderstanding, we have to actively fight against that, keeping lines of communication open, and always focusing on civility and respect.
Thankfully, there are more than 130 debates in our archive that are designed to challenge your point of view – in a way your brain will welcome. Hear both sides engage in a thoughtful, considerate and open-minded dialogue on even the most polarizing topics. We know the debate format works: more than 50% of our listeners change their minds when exposed to the other side.
