Probabilistic Diagnosis

It is argued that it is preferable to evaluate probabilistic diagnosis systems in terms of utility (patient benefit) or loss (negative benefit). We have adopted the provisional strategy of scoring performance as if the system were the actual decision-maker (not just an aid to him) and argue that a rational figure of merit is given by the average loss which patients would incur by having the system decide on treatment, the treatment being selected according to the minimum expected loss principle of decision theory.A similar approach is taken to the problem of evaluating probabilistic prognoses, but the fundamental differences between treatment selection skill and prognostic skill and their implications for the assessment of such skills are stressed. The necessary elements of decision theory are explained by means of simple examples mainly taken from the acute abdomen, and the proposed evaluation tools are applied to Acute Abdominal Pain data analysed in our previous papers by other (not decision-theoretic) means. The main difficulty of the decision theory approach, viz. that of obtaining good medical utility values upon which the analysis can be based, receives due attention, and the evaluation approach is extended to cover more realistic situations in which utility or loss values vary from patient to patient.

Quantum Decision Theory

Abstract Quantum decision theory corrects categorical and propositional logic pathologies common to classic statistical goal-oriented reasoning, such as rational neuroeconomics-based optimal foraging. Within this ecosalient framework, motivation, perception, learning, deliberation, brain computation, and conjunctive risk-order errors may be understood for subjective utility judgments underlying either rational or irrational canonical decisions-actions used to choose, procure, and consume rewarding nutrition with variable fitness.

Psychological Studies

Several psychological studies linking creativity with unorthodox religious beliefs were reviewed. The conclusion that orthodox belief and creativity are infrequently found together in our time and culture was accepted as probably valid but by no means inevitable. Scientific creativity was analyzed by applying a decision theory approach to scientific behavior. Outstanding scientific creativity was viewed as, in part, resulting from a decision strategy to “ Discover truth by any means” rather than to “Avoid error at all costs.” An important parallel between scientific creativity and the dynamics of faith was delineated, suggesting that an improved understanding of this kinship might remove some mental obstacles to creativity among orthodox believers in our culture.
