as uncertainty one designates a lack of knowledge, which is consciously noticed. If the lack of knowledge is not noticed, one speaks of unawareness.
According to George Klir can be differentiated different kinds by uncertainty:
- Non specificity - an uncertainty over the meaning of an ambiguous statement and/or. a condition (lack of information content).
- Indistinct one - the uncertainty over the certainty of a degree (lack of accuracy).
- Dissonance - the uncertainty with the selection of different alternatives (lack of a decision)
- confusion - which uncertainty with that is not clear, for which it goes at all (lack of understanding)
has for example a person in a test an unknown score reached, then can the following uncertainties occur:
- Does the result lie in the upper, middle or lower third of all test participants? (Non--specificity)
- the own estimate of the score is in a diffuse way
- the person the test existed or not? (Dissonance)?
- Oh, there were points? What for a test? (Confusion)?
The probability theory concerns itself only with questions of the dissonance (“which case applies with which security? ”), while for example with the Fuzzy logic also different forms of the uncertainty can be treated.
