Background: Civilian evacuation during armed conflict is a critical aspect of humanitarian response, yet it remains under-researched compared to natural disaster evacuation. The ongoing Russian invasion of Ukraine provides a high-stakes, real-world case study to analyze the factors influencing individual evacuation decisions. This article explores how psychological and behavioral economics principles, such as prospect theory, loss aversion, and social norms, influence civilian movement in a war-torn environment.

Methods: This study employs a mixed-methods approach. It synthesizes qualitative data from journalistic reports and eyewitness accounts with quantitative conflict data from sources like the Uppsala Conflict Data Program and DeepStateMap to correlate battlefront proximity with population movement. The theoretical framework is grounded in behavioral science, particularly the concepts of loss aversion and the effectiveness of informational nudges. The analysis aims to understand how civilians weigh the risks of staying against the psychological and material costs of leaving.

Results: The findings indicate that while some civilians evacuate in response to clear threats, a significant portion chooses to remain in conflict zones, even when presented with severe and immediate danger. This behavior is strongly associated with loss aversion, where the potential loss of property, community, and personal history outweighs the perceived gain of physical safety. Social norms and community cohesion also play a critical role, as individuals are more likely to stay or leave based on the decisions of their neighbors and local networks. The data reveals a non-linear relationship between observable threats and evacuation rates, which challenges the simplicity of traditional risk-assessment models.

Conclusion: The case of Ukraine demonstrates that civilian evacuation in conflict is a complex, behaviorally-driven process that cannot be fully explained by rational choice models alone. The decision to evacuate is profoundly shaped by an attachment to place and a deep-seated aversion to the psychological and material loss associated with displacement. This study concludes that simple, one-size-fits-all predictive models for civilian evacuation are insufficient. Effective humanitarian and military planning must incorporate a nuanced understanding of these psychological and sociological factors to accurately anticipate and respond to civilian movement in conflict zones.
