[Judgements and emotional reactions about socially unjust situations].

Our research studies investigated situations involving perceived social injustice. In the first study, we collected 79 items involving unjust situations from 213 undergraduate students. Then, 270 undergraduates completed a questionnaire evaluating the social injustice for these situations. The results of a factor analysis showed that these 79 unjust situations could be classified into four types: (a) deviation from social norms, (b) inhumanity, (c) lack of economic benefit, and (d) deviation from interpersonal norms. In a second research study, we collected 124 items involving unjust situations from 599 undergraduates. The results of factor analyses of data from 386 undergraduates showed eight factors: (a) deviation from public rule, (b) deviation from public manner, (c) violence, (d) misery, (e) low benefit, (f) others benefit by incorrect ways, (g) aggression against others, and (h) lack of concern for others. In a third study, we measured the emotional reactions of 224 undergraduates for 96 of the unjust situations collected in Study 2. The results showed that the emotional reactions differed for each unjust situation.
