    Risk Assessment and Rational Decision Theory.Roger M. Cooke - 1982 - Dialectica 36 (4):329-351.
    SummaryI contend on both theoretical and historical grounds that quantitative risk assessment is relevant for policy determination only as a cost estimate. In particular, it provides a method for estimating the costs of a hypothetical insurance policy against the potential liabilities associated with a given course of action. It is not relevant to the question of rational choice under risk.RésuméJe montre, en partant d'arguments aussi bien théoriques qu'historiques, que le calcul quanti‐tatif des risques n'aide à la détermination d'une politique à (...)

    Conceptual Fallacies in Subjective Probability.Roger M. Cooke - 1986 - Topoi 5 (1):21-27.
    Subjective probability considered as a logic of partial belief succumbs to three fundamental fallacies. These concern the representation of preference via expectation, the measurability of partial belief, and the normalization of belief.

    Probabilistic Reasoning in Expert Systems Reconstructed in Probability Semantics.Roger M. Cooke - 1986 - PSA: Proceedings of the Biennial Meeting of the Philosophy of Science Association 1986:409 - 421.
    Los's probability semantics are used to identify the appropriate probability conditional for use in probabilistic explanations. This conditional is shown to have applications to probabilistic reasoning in expert systems. The reasoning scheme of the system MYCIN is shown to be probabilistically invalid; however, it is shown to be "close" to a probabilistically valid inference scheme.

    The Representation of Takeuti's *20c ||_ -Operator.Roger M. Cooke & Michiel Lambalgen - 1983 - Studia Logica 42 (4):407 - 415.
    Gaisi Takeuti has recently proposed a new operation on orthomodular lattices L, ⫫: $\scr{P}(L)\rightarrow L$ . The properties of ⫫ suggest that the value of ⫫ $(A)(A\subseteq L)$ corresponds to the degree in which the elements of A behave classically. To make this idea precise, we investigate the connection between structural properties of orthomodular lattices L and the existence of two-valued homomorphisms on L.
