In situations of high stress, fear or distrust, the hormone and neurotransmitter cortisol floods the brain. Executive functions that help us with advanced thought processes like strategy, trust building, and compassion shut down. And the amygdala, our instinctive brain, takes over. The body makes a chemical choice about how best to protect itself — in this case from the shame and loss of power associated with being wrong — and as a result is unable to regulate its emotions or handle the gaps between expectations and reality.
When you argue and win, your brain floods with different hormones: adrenaline and dopamine, which makes you feel good, dominant, even invincible. It’s a the feeling any of us would want to replicate. So the next time we’re in a tense situation, we fight again. We get addicted to being right."
