Impression management (IM) concerns can lead to significant psychological consequences, potentially engendering unethical behavior. Therefore, adopting the stressor–strain–outcome framework, this study explores the effects of IM concerns on unethical behavior through wellbeing, and whether IM on social media (i.e., Instagram) triggers fatigue and results in unethical behavior at work. The findings of two empirical studies (n = 480 and n = 299) in different settings (Kuwait and the UK) suggest that women experience higher effects from IM concerns compared with men in Kuwait, while no gender differences are found in the UK. The results also confirm that impression management on social media platforms triggers fatigue, in turn increasing unethical behavior at work. This study contributes to the IM literature by capturing the effect of Instagram activities on workplace behavior.

In the field of ethical consumption, research in recent years has attempted to explain the gap between principles and actual behaviour. Three experimental studies show that when the contradiction between what individuals say and what they do is made salient in the field of environmental protection, that is to say in a situation of induced hypocrisy, they indirectly reduce the resulting cognitive dissonance by being more altruistic towards associations that act for the environment but not towards humanitarian associations. This effect of induced hypocrisy fades as individuals become less vulnerable to the threat to the self by affirming values that are important to them.

Dans le domaine de la consommation pro-environnementale, les recherches se sont évertuées ces dernières années à expliquer l’écart existant entre les attitudes et les comportements effectifs. Trois études expérimentales montrent que lorsque la contradiction entre ce que les individus disent et ce qu’ils font est rendue saillante, c’est-à-dire dans une situation d’hypocrisie induite, ils réduisent de manière indirecte la dissonance cognitive qui en résulte en étant plus altruistes à l’égard d’associations qui agissent pour l’environnement mais pas pour des associations humanitaires. Cet effet de l’hypocrisie induite n’est plus significatif lorsque les individus ont pu, au préalable, affirmer leur Soi.
