Forty four male soldiers took part in this study. They were confronted with dilemmas of two kinds: a Lottery type, involving two objectively equal ways of winning a prize, and a "Heaven-Hell" type, where a choice was to be made between long and short periods of time spent in Hell and Heaven. Various personality questionnaires and intelligence tests were also administered. In spite of their formal similarity, no relationship was found between the two kinds of dilemmas, As far as the Lottery type concerned, we were able to conclude that people who "look at the bright side of things" differ from the others in several personality vaiables: Authoritarianism, Conformity, Leadership, Wanted Inclusion, Expressed Affection and Category Width. Three highly frequent patterns of response were yielded by the "Heaven-Hell" type. The mean scores of these groups were significantly different in Support, Conformity and Self Orientation. The results, although tentative, indicate that interpersonal values may be promising variables underlying decision-making.
