Optimisme comparatif dans le milieu professionnel : l'influence de la fréquence et de la gravité sur la perception des risques d'accident du travail

The aim of this study is to test if people express comparative optimism when they evaluate their risk of being confronted to various work accidents compared to their colleagues. We also test the assumption according to which individuals are as much more optimistic as the event is threatening. Thus, an accident which is serious and probable (and consequently more threatening) should generate a maximum of comparative optimism. Our population is composed by employees of a mirror manufacture company. The latter evaluated their personal risk and that of one of their colleagues to be confronted with a severe /rare, severe/frequent, non severe/rare or non severe/frequent accident. Our results reveal the presence of an optimistic bias and this particularly for the severe and frequent accident. These data are discussed in terms of defensive bias and self esteem maintenance.
