Since economics focuses on individual behaviour and implicitly adopt a methodological individualism, an individual rationality hypothesis must be laid down. Beyond the usual substantive rationality hypothesis, others forms of individual rationality can be found in economics theory. They are often related to the Simon's bounded rationality hypothesis. In the economics literature the meanings of the bounded rationality hypothesis are obviously diverse and sometimes based on a partial or superficial readings of Simon's writings. Moreover, each one of these meanings is implicitly closely linked with a particular methodological and epistemological position. Based on careful readings of Simon's w…
Validité et fiabilité des questionnaires d'évaluation de la qualité de vie : une étude appliquée aux accidents vasculaires cérébraux
This article deals with various means, which could be used by designers in order to estimate error terms in questionnaire tests results, thanks to psychometry. The study must be conceived so as to minimize systematic errors (validity) and random errors (reliability). Methods settled to test the validity of a study are very subjective, even if some of them seem to be more "scientific", being based on the principle of correlation. However the last-mentined don't stand up to some theoretic weakness and other explicit subjective methods should be chosen instead : for instance experts consensus.Methods of reliability evaluation have been developed under strong hypothesis to estimate a reliabilit…
