Résumé 139 étudiants ont évalué la désirabilité et l'utilité sociale de 308 adjectifs de personnalité et de 297 professions. Les évaluations moyennes et les écart types sont donnés pour chaque item et pour chaque type d'évaluation (désirabilité et utilité sociale). Pour chaque item un t de Student a été calculé entre les deux évaluations. Les corrélations entre ces évaluations et trois autres normes de désirabilité (en anglais et en français) varient entre .87 et .96. Mots clés : désirabilité, utilité sociale, adjectifs, professions.

Comparative optimism can be defined as a self-serving, asymmetric judgment of the future. It is often thought to be beneficial and socially accepted, whereas comparative pessimism is correlated with depression and socially rejected. Our goal was to examine the social acceptance of comparative optimism and the social rejection of comparative pessimism in two dimensions of social judgment, social desirability and social utility, considering the attributions of dysphoria and risk-taking potential (studies 2 and 3) on outlooks on the future. In three experiments, the participants assessed either one (study 1) or several (studies 2 and 3) fictional targets in two dimensions, social utility and social desirability. Targets exhibiting comparatively optimistic or pessimistic outlooks on the future were presented as non-depressed, depressed, or neither (control condition) (study 1); non-depressed or depressed (study 2); and non-depressed or in control condition (study 3). Two significant results were obtained: (1) social rejection of comparative pessimism in the social desirability dimension, which can be explained by its depressive feature; and (2) comparative optimism was socially accepted on the social utility dimension, which can be explained by the perception that comparatively optimistic individuals are potential risk-takers.

Abstract. This paper investigates the specific self-presentational situations in which people confirm or negate their comparative optimism in order to convey a favorable self-image. One pilot study and three experiments showed that people increase their comparative optimism to convey an image of competence, but not one of warmth (Pilot Study, Study 1), as well as to present an advantageous self-image in professional situations, although not in friendship situations (Studies 2–3). These effects occur in self-presentation situations involving both low (Studies 1–2) and high (Study 3) levels of accountability. Additional findings indicate that the presentation of a risk-taking self-image is unrelated to comparative optimism, whereas the presentation of a modest self-image leads people to decrease their comparative optimism estimates (Study 3). Results are discussed in the light of the underlying self-presentational motivations in specific situations.
