**9. Conclusion**

What can be concluded from the decisional inabilities identified in this document? We observe firstly the importance of the internal consistency of the paradigm, in particular that required between the characteristics of the information and the tools used to process it. We then note that all subjective references involving the personal knowledge and experience of the decision-makers have been carefully avoided. The Italian statistician de Finetti (1906–1985) proposes abandoning the objective definition of probability without this affecting the quality of the judgements. The method used is that of the odds applied to bets on racecourses. This type of quantification known as "subjective probability" is considered as expressing the "degrees of belief" which are clearly cognitive.
