Information

informativeinputinputs
Uncertainty refers to epistemic situations involving imperfect or unknown information.
Information can be thought of as the resolution of uncertainty; it is that which answers the question of "what an entity is" and thus defines both its essence and nature of its characteristics.

Expectation (epistemic)

expectationexpectationsexpect
In cognitive psychology, uncertainty can be real, or just a matter of perception, such as expectations, threats, etc.
In the case of uncertainty, expectation is event that considered the most likely to happen.

Ambiguity

Ambiguity is a form of uncertainty where even the possible outcomes have unclear meanings and interpretations.
A common aspect of ambiguity is uncertainty.

Subjective logic

opinionsubjective belief
This form of vagueness can be modelled by some variation on Zadeh's fuzzy logic or subjective logic.
Subjective logic is a type of probabilistic logic that explicitly takes uncertainty and source trust into account.

Risk

Risk can also be defined as the intentional interaction with uncertainty.

Economics

It arises in any number of fields, including insurance, philosophy, physics, statistics, economics, finance, psychology, sociology, engineering, metrology, meteorology, ecology and information science.
Uncertainty in economics is an unknown prospect of gain or loss, whether quantifiable as risk or not.

Knightian uncertainty

uncertaintyFrank Knightfundamental uncertainty
;Knightian uncertainty: In economics, in 1921 Frank Knight distinguished uncertainty from risk with uncertainty being lack of knowledge which is immeasurable and impossible to calculate; this is now referred to as Knightian uncertainty:
Knightian uncertainty is named after University of Chicago economist Frank Knight (1885–1972), who distinguished risk and uncertainty in his work Risk, Uncertainty, and Profit:

Physics

It arises in any number of fields, including insurance, philosophy, physics, statistics, economics, finance, psychology, sociology, engineering, metrology, meteorology, ecology and information science.
With the standard consensus that the laws of physics are universal and do not change with time, physics can be used to study things that would ordinarily be mired in uncertainty.

Propagation of uncertainty

error propagationtheory of errorspropagation of error
In statistics, propagation of uncertainty (or propagation of error) is the effect of variables' uncertainties (or errors, more specifically random errors) on the uncertainty of a function based on them.

Uncertainty quantification

Uncertainty quantification (UQ) is the science of quantitative characterization and reduction of uncertainties in both computational and real world applications.

Volatility, uncertainty, complexity and ambiguity

VUCA
VUCA is an acronym – first used in 1987, drawing on the leadership theories of Warren Bennis and Burt Nanus – to describe or to reflect on the volatility, uncertainty, complexity and ambiguity of general conditions and situations; The U.S. Army War College introduced the concept of VUCA to describe the more volatile, uncertain, complex and ambiguous multilateral world perceived as resulting from the end of the Cold War.
