As uncertainty is called a consciously perceived lack of security or (in a scientific context) to reliability and validity . An actual lack of security is also known as danger .

Uncertainty in decision theory

In decision theory , future environmental conditions for which there are no probabilities are described with uncertainty . Uncertainty is divided into uncertainty , risk and ignorance . In the case of uncertainty , the possible effects are known, but no information is available on the probability of occurrence. In the case of risk , the probability of occurrence is known as additional information, but not the time. In the case of ignorance , the effects of the alternative courses of action examined are also not fully known. Decision theory offers different methods of decision making under uncertainty , decision under uncertainty and decision under risk . Applying mathematical models to represent uncertainty is extremely difficult.

Self insecurity in psychology

There is also the importance of self-insecurity as a subjective-emotional state of a living being as a result of a lack of trust or fearfulness in contrast to self-confidence . This condition can express itself in humans as a personality trait in avoidance behavior and is also referred to in psychiatry as self-insecurity-avoiding personality disorder .

Uncertainty in measurement technology and in the natural sciences

When measuring a physical quantity , an uncertainty arises which can have various causes. It is called the measurement uncertainty .

The fact that certain measurands generally cannot be measured exactly at the same time is a fundamental principle of quantum mechanics and is formulated in Heisenberg's uncertainty principle .

Uncertainty in risk management

The ISO 31000 standard defines risk as the effect of uncertainty on the degree of goal achievement. Uncertainty is described here with the "total or partial lack of information".
