Black swans exist. I love the "Black Swan" theory that discusses how the psychological biases that make people individually and collectively blind to uncertainty and unaware of the massive role of the rare event in historical affairs. It further explains the disproportionate role of high-impact, hard-to-predict, and rare events that are beyond the realm of normal expectations.
