Abstract
Groups often display shared emotional climates that shape collective behavior and decision-making. While emotional contagion and groupthink have been extensively studied, less is known about how high-intensity and normatively regulated group emotions can become counterproductive. This paper introduces the concept of the Groupfeel syndrome—a dysfunctional group-level emotional dynamic characterized by intense shared emotions, pressure to maintain emotional positivity, and the absence of emotionally intelligent regulation. Drawing on two revelatory qualitative cases—a former member of a closed spiritual community and a former financial trader operating in a high-pressure market environment—I identify three antecedent conditions that foster this syndrome and propose eight testable hypotheses. Groupfeel impairs critical thinking, suppresses dissent, and biases collective decision-making by locking groups into rigid affective trajectories. Grounded in psychological and organizational literature and supported by qualitative data from contrasted high-stakes contexts, the model integrates mechanisms of emotional contagion, normative emotion regulation, and social conformity. This conceptual development paper advances research on group emotion by specifying when shared affect shifts from a resource to a liability and outlines implications for organizational behavior, leadership, and future empirical testing.
