Summary/Abstract: Empirical data suggest, that in many situations people are not able to estimate the probability of events on the base of available information in a way consistent with the normative model. This fact influences the choice of conclusions which are considered to be rational. The article outlines the factors that may affect the assumed value of a priori probability and – indirectly – the value of a posteriori probability. All these factors will be collectively referred to as the parameter j. Its value depends on the context in which the reasoning is made. In the article I show, that a critical assessment of our reasoning is not always justified.
