The default setting of the brain
Updated: Sep 6, 2017
In general, the default setting of the brain is to overestimate threats, underestimate opportunities, and underestimate resources both for coping with threats and for fulfilling opportunities. Then we update these beliefs with information that confirms them, while ignoring or rejecting information that doesn’t. There are regions in the amygdala, which an almond-shaped part of our limbic system that’s intricately connected to the body’s “stress response” that’s specifically designed to prevent the unlearning of fear, especially from childhood experiences. As a result, we end up preoccupied by threats that are actually smaller or more manageable than we’d feared, while overlooking opportunities that are actually greater than we’d hoped for.
