Uncertainty vs. Risk

Concept
Definition
Distinguishing between uncertainty and risk, Yuen Yuen Ang defines uncertainty as open-ended possibilities—both good and bad—that cannot be known in advance, whereas risk means negative outcomes that can be calculated and controlled. In short, for Ang, risk is calculable probability; uncertainty is unknown possibility. Whereas risk can be controlled, uncertainty calls for influence, imagination, and discovery.

Quotes
[Uncertainty does not mean risk] We face risks in complicated worlds but uncertainty in complex worlds.
Complex systems can evolve and generate uncertainty, that is, possibilities that are beyond the anticipation and planning of agents within the system. Some possibilities are terrible, such as stock market crashes and outbreaks of war. Yet some possibilities are marvelous, such as scientific breakthroughs, artistic innovations, and the information revolution that we are currently experiencing.
To extinguish uncertainty is to extinguish possibilities, both terrible and marvelous.
Risks may be predicted and controlled to a varying extent, but possibilities may only be imagined.

[Uncertainty calls for influence, not control] A world of complexity, however, is full of uncertainty. Even authoritarian leaders sometimes do not know what precise outcomes they prefer or what solutions may arise. In a complex world, as we find in political economies, influencing processes of change and empowering ground-level actors to find their own solutions promises to be more fruitful than trying to control exact outcomes.

[Designing industrial policy under uncertainty requires discovery] My premise is that uncertainty—all the unknown possibilities, both good and bad—is distinct from risk, meaning negative outcomes whose probability of occurrence can be calculated and controlled. Under uncertainty, preselecting outcomes is not only futile but potentially counterproductive, since it may lead governments to miss opportunities that defy their initial expectations. Instead of controlling, governments must exercise influence… Under uncertainty, the challenge for industrial policy is not simply picking winners but discovering them. And once they are discovered, it is essential to tailor support beyond the usual toolkit of tariffs and subsidies.
