How we deal with ambiguity seems to be connected to how your brain is wired. Some people require a concrete plan and other people like to just wander. This might explain the source of our recent political divides. I recently listened to a podcast that deals with this subject by Shankar Vedantam, science journalist and host of The Hidden Brain podcast titled Sitting With Uncertainty. A summary of the podcast:It can sometimes be exciting when we don't know what's coming next. Other times, the unknown can be deeply troubling. This week, we talk with researcher Dannagal Goldthwaite Young about how we respond to uncertainty, and why this psychological trait plays a surprisingly large role in shaping our behavior, perspectives — even our political beliefs.
