", "\nAbstract\n\nObjective\nExogenous shocks trigger rally effects, leading the public opinion toward increased trust in institutions. Rally effects have an important social function because they help society react to shocks rapidly and efficiently as a single unit and cohesively face the threat. However, little is known about the individual functions that these effects fulfil. In this study, we aimed to analyze the individual functions of the rally effect.\n\n\nMethod\nIn a three‐wave longitudinal study on a quota sample of the Italian adult population (N = 1070), we analyzed the individual consequences of the increase in institutional trust triggered by the COVID‐19 pandemic.\n\n\nResults\nA path analysis showed that increased trust in political, super partes and international institutions fostered well‐being, reducing anxiety, collective angst, and anger via the mediation of participants’ perceived control over their lives.\n\n\nConclusion\nBeyond their well‐known social functions, rally effects fulfil the individual function of favoring people's psychological well‐being.\n\n"]
