In 1921, economist Frank Knight wrote a book about risk, uncertainty and profit. Risk is where the outcome is unknown, but it is possible to measure the odds of the risk happening; these are known unknown events. Uncertainty, in Knight’s world, is where the outcome is unknown and it is not possible to measure the odds. These black swan risks are inherently unpredictable even though we know they exist; these are unknown unknowns.
Investors manage risk daily with their buy and sell decisions and live with the possibility of uncertainty. The risk inherent in movements in the oil price can be planned; the uncertainty of a plague creating havoc in the global economy cannot be priced in until it happens.
Having made the rules that permitted fines for non-compliance, sometimes resulting in grandparents being left to die alone, Cummings took the quantifiable risk of passing the virus on to his parents. The problem was not just Cummings’ flagrant disregard of the odds but also the uncertainty with which he had presented the rules without clear advice or authority.
