The authors, O. S. Athira, K. Alphonsa Jose, and Neema Ann Philip of the School of Psychological Sciences at Christ University in Bangalore, are careful to frame their proposal as a heuristic rather than a settled theory. This distinction matters. A heuristic is a device for organizing questions and generating hypotheses; a theory, by contrast, claims to describe mechanisms that have already been demonstrated. The researchers argue that individual trauma frameworks—developed to explain what happens within a single person’s nervous system when confronted with overwhelming or inescapable threat—cannot simply be transplanted wholesale onto entire societies. Societies do not possess a nervous system, a unified psyche, or a diagnosable clinical disorder. What the heuristic borrows instead is a vocabulary: a way of describing the recurring pattern in which awareness of ecological threat coexists with affective distancing, avoidance of sustained engagement, and a diminished sense that individual or collective action can matter.

This pattern, the authors contend, is not captured by existing measurement tools. Instruments such as the Climate Change Anxiety Scale and the Hogg Eco-Anxiety Scale index the intensity of climate-related worry and the degree of functional impairment it produces. They are designed to assess how distressed a person feels. Collective climate disengagement, as proposed in the Perspective, targets something different: the co-occurrence of registered concern with emotional numbing and reduced perceived efficacy. A person could score high on climate anxiety yet still be caught in the disengagement pattern, or conversely could show little overt anxiety while remaining affectively distanced from the issue. The construct also overlaps with, but is not identical to, climate denial, low climate efficacy, or political disengagement, which is precisely why the authors argue a new operational definition is needed.

The intellectual landscape the Perspective enters is already crowded with explanations for the gap between concern and action. Political polarization, material interests tied to fossil-fuel dependence, informational deficits, and low perceived efficacy all play documented roles, and the authors are explicit that these accounts remain indispensable. Psychological processes, they stress, should not be treated as substitutes for structural explanation; they form one interacting layer in what is fundamentally a multi-level conservation problem. What the trauma-informed heuristic adds is a candidate pathway through which chronic, diffuse, and difficult-to-control threat may narrow emotional processing and perceived agency at the population level—without displacing the structural and political drivers that shape who can act and who cannot.

The proposal also engages with a parallel sociological tradition. Earlier scholarship has catalogued psychological barriers to climate action, including limited cognition, ideological worldviews, and sunk-cost effects. Other researchers have argued that climate change constitutes a form of cultural trauma, with societies defending existing structures through social inertia at individual, institutional, and societal levels, drawing on concepts of habitus, field, and doxa. That account explains resistance to change as a property of social systems. The Bangalore team’s heuristic differs in both mechanism and aim: rather than offering a grand theoretical synthesis, it borrows individual-level threat-regulation and dissociation theory to generate a testable psychological pattern, oriented toward a concrete measurement and intervention agenda.

Central to the proposed model is the concept of overwhelm. Chronic ecological threat—amplified by structural conditions such as inequality, institutional failures, concentrated political power, and uneven access to meaningful action—is proposed to interact in ways that produce climate-related overwhelm. This overwhelm, in turn, is hypothesized to relate to the mediating pathway of affective distancing, avoidance, and reduced perceived efficacy, which ultimately feeds into reduced sustained engagement. Crucially, the model identifies moderators: social support, facilitated emotional processing, collective efficacy, and accessible action opportunities are proposed to weaken the link between overwhelm and disengagement. This is where the framework’s practical implications emerge, because each moderator is potentially amenable to intervention.

The authors draw selectively on Polyvagal Theory, which has been influential in clinical discussions of threat and emotional regulation. They acknowledge candidly that several of the theory’s evolutionary and neurophysiological claims remain scientifically debated, and they use it only as one interpretive vocabulary rather than as a settled explanation of climate-related behavior. Similarly, structural dissociation theory—which distinguishes ordinary day-to-day functioning from trauma-linked emotional material that remains difficult to integrate—supplies the analogy at the social level. Institutions, media, consumption routines, and everyday interaction continue running on schedule while grief, fear, guilt, and awareness of ecological loss receive little sustained collective processing. The patterned separation between knowledge, emotion, and action is what the authors find analytically useful, not any literal claim that a society dissociates.

Importantly, the heuristic predicts heterogeneity rather than uniformity. Climate engagement is shaped by culture, material security, local exposure to climate impacts, political power, Indigenous and local knowledge, historical responsibility for emissions, and access to collective infrastructures for action. A trauma-informed account, the authors argue, is strongest when it complements these determinants rather than individualizing them—when it explains why similarly informed people in different circumstances disengage differently, rather than locating the entire problem inside individual psychology.

The Perspective builds on newer work that reframes climate change itself as a source of collective trauma rather than merely a cause of individual distress. That literature has begun naming
