In real life applications, both kinds of uncertainties are present. Uncertainty quantification intends to explicitly express both types of uncertainty separately. The quantification for the aleatoric uncertainties can be relatively straightforward, where traditional (frequentist) probability is the most basic form.
Taking into account uncertainty arising from different sources, whether in the context of uncertainty analysis or sensitivity analysis (for calculating sensitivity indices), requires multiple samples of the uncertain parameters and, consequently, running the model (evaluating the -function) multiple times. Depending on the complexity of the ...
Anxiety for the purposes of anxiety/uncertainty management can be described as an apprehension based on the fear of negative consequences. It is more prevalent in intergroup relations because there is an added fear of appearing prejudiced when dealing with an outgroup.

Because uncertainty is dependent upon perspective, "a person who believes himself or herself to be uncertain is uncertain." [2] However, people have different appetites and tolerances for uncertainty. For some ...
In daily life, measurement uncertainty is often implicit ("He is 6 feet tall" give or take a few inches), while for any serious use an explicit statement of the measurement uncertainty is necessary. The expected measurement uncertainty of many measuring instruments (scales, oscilloscopes, force gages, rulers, thermometers, etc.) is often stated ...
