Brain Scans Link Soccer Fandom to Neural Pathways Driving Intense Emotion and Potential for Polarization
BOSTON (WHN) – Neurobiological circuits that fuel the intense passion of soccer fans, and their occasional rage, may offer insights into broader societal divisions, according to a study published in Radiology, a journal of the Radiological Society of North America (RSNA). Researchers found that watching their favorite team play activates specific brain regions associated with reward and control, with the intensity of these responses varying dramatically based on game outcomes, particularly in matches against rivals.
The study, which utilized functional magnetic resonance imaging (fMRI) to observe brain activity, scanned 60 healthy male soccer fans. These participants, aged 20 to 45, all supported one of two historically rival teams. The findings suggest that the same neural mechanisms driving sports fanaticism could also be at play in other forms of group allegiance and conflict, with the authors positing that these emotional circuits begin forming early in life.
Francisco Zamorano, a biologist and associate professor at Universidad San Sebastián in Santiago, Chile, and lead author of the study, stated that soccer fandom provides a “high-ecological-validity model of fanaticism with quantifiable life consequences for health and collective behavior.” He explained that while social affiliation is well-studied, the neurobiological underpinnings of social identity within competitive contexts remain less clear. The research team aimed to investigate the brain mechanisms behind emotional responses in fans to their teams’ victories and defeats.
Participants completed the Football Supporters Fanaticism Scale, a questionnaire assessing “Inclination to Violence” and “Sense of Belongingness.” During fMRI scans, they viewed 63 goal clips. These clips featured their own team, their rival team, or a neutral team. The researchers specifically compared brain responses to goals scored by their team against a rival versus goals scored by the rival team against them. Control conditions involved goals from non-rival teams.
The data revealed significant shifts in brain activity correlating with team success or failure. Dr. Zamorano noted that rivalry “rapidly reconfigures the brain’s valuation-control balance within seconds.” In cases of significant victory, the brain’s reward circuitry showed amplified activity compared to non-rival wins. Conversely, during significant defeats, the dorsal anterior cingulate cortex (dACC), a region critical for cognitive control, exhibited “paradoxical suppression of control signals.”
Paradoxical suppression, as described by the researchers, occurs when an attempt to inhibit a thought, feeling, or behavior inadvertently intensifies it. The scans indicated heightened activity in reward regions when a participant’s team scored against a rival, suggesting that rivalry can bolster in-group cohesion and reinforce social identity. This effect was most pronounced in highly devoted fans, whose self-regulatory systems appeared to temporarily falter when their team’s identity felt threatened. This could explain impulsive reactions observed in some fans during critical game moments.
Clinically, Dr. Zamorano suggested, “the pattern implies a state-dependent vulnerability whereby a brief cooling-off or removal from triggers might permit the dACC/salience control system to recover.” He further posited that the observed neural signature—reward amplified, control diminished under rivalry—is likely applicable beyond sports, extending to political and sectarian conflicts.
Understanding these brain mechanisms, the study authors suggest, could inform strategies for communication, crowd management, and preventative measures at emotionally charged events. “Studying fanaticism matters because it reveals generalizable neural mechanisms that can scale from stadium passion to polarization, violence and population-level public-health harm,” Dr. Zamorano stated. He emphasized the critical role of early life development, noting that “caregiving quality, stress exposure, and social learning sculpt the valuation-control balance that later makes individuals vulnerable to fanatic appeals.” The protection of childhood, he argued, represents the most effective prevention strategy.
The authors highlight soccer fandom as an ethical, controlled environment for studying these neural processes and for testing interventions applicable to broader social issues, such as political division, sectarian conflict, and online tribalism. Dr. Zamorano underscored the urgency of this research given current global tensions and political polarization. He drew a parallel between the study’s findings and events like the January 6, 2021, U.S. Capitol assault, where intense group identity appeared to override democratic norms due to a breakdown in cognitive control.
“The participants showed classic signs of compromised cognitive control, exactly what our study found in the reduced dACC activation,” he commented. Investigating fanaticism, he concluded, is not merely descriptive but offers “developmentally informed prevention that protects public health and strengthens democratic cohesion.”
