CONFIANCE EXCESSIVE: CONNAISSANCES ET CROYANCES

It had already been found (Lamarche 1988; Oskamp 1965) that the overconfidence shown in answering a question increased with the number of new informations given. The objective of our research was to verify if there was a relation between that phenomenon, obtained with knowledge questions, and the evolution of confidence, in the same circumstances, when belief questions are involved. On the one hand, we presented to our subjects knowledge questions which were repeated with a growing number of clues; on the other hand, the same subjects were asked to form an impression of a person based on a list of traits presented sequentially. Using a calibration index, we were able to observe anew the growing overconfidence with knowledge questions. However, in the case of beliefs, the confidence level did not grow in the same way. We explain that result by our choice of traits. Nevertheless, there was a relation between the increase of confidence and the decrease of calibration. We think this could be the result of a lack of involvement with the belief questionnaire which is less so when answered first.     

Grading the ‘cultural literacy’ project

The essay examines the argument advanced by E.D. Hirsch, Jr., for instituting ‘cultural literacy’ as a fundamental priority of schools. A number of confusions and equivocations in Hirsch's reasoning are identified, and the propensity of his project to indoctrinate is exposed. Among the features of Hirsch's argument shown to be troubling are his shifting construal of ‘language’, his inconsistency about the requirements of cultural literacy, and his uncritical relation to traditional images of the American past and present. The upshot is to raise the question why Hirsch's project has elicited wide support and praise.
