Risk vs. Uncertainty: What's the Difference?

Edited by Janet White || By Harlon Moss || Updated on October 25, 2023
Risk involves known probabilities of outcomes; uncertainty denotes unknown probabilities or outcomes.

Key Differences

Risk refers to situations where outcomes, even if unpredictable, have quantifiable probabilities attached to them. Uncertainty, on the other hand, alludes to scenarios where it's impossible to determine the likelihood or even anticipate the potential outcomes.
In the realm of investments, risk allows an investor to measure the potential gains or losses, thereby making informed decisions. Uncertainty is more challenging for decision-making, as one cannot predict or gauge the possible results or the chances of them occurring.
The concept of risk often requires a calculated approach, relying on data, past experiences, or statistical models to assign probabilities. Uncertainty lacks this framework, leaving individuals or businesses to base decisions on intuition, guesswork, or subjective judgment.
While risk can sometimes be managed, reduced, or even insured against, uncertainty presents a more complex challenge. Managing uncertainty often requires flexibility, adaptability, and preparedness for unforeseen events.

While it's challenging to reduce uncertainty, gathering more information can provide better clarity.

Is risk always associated with negative outcomes?

No, risk denotes a probability, which could lead to positive, negative, or neutral outcomes.

How can one differentiate between risk and uncertainty?
