Marks argues the belief that there is no risk is the riskiest thing because it encourages dangerous behavior.
“the riskiest thing in the world is the belief that there's no risk. Because when police when people believe there's no risk, they act in very risky ways, which makes the world a risky place.”
Crisis psychology collapses the distinction between what's possible and what's probable.
“During the crisis, any optimistic scenario was dismissed as naive. Everything bad seemed possible, and therefore probable. The distinction between possibility and probability vanished. That’s the real psychological poison in markets.”
