A new study has found that synchronised chanting among football fans can make them appear more formidable to both their own group and rival supporters. But contrary to previous assumptions, the effect does not necessarily translate into heightened feelings of threat among outgroups. The findings were published in the journal Evolution and Human Behavior.
Researchers investigated the impact of synchronised chanting on perceptions of group strength, outgroup threat, and behaviour among Brazilian football fans. The study involved 771 participants who were randomly exposed to either a synchronous or asynchronous recording of a football chant. They were then asked to evaluate the formidability of the chanting group and the level of threat they felt from rival fans.
The findings showed that groups engaging in synchronised chanting were perceived as more formidable by both their own members and opposing supporters. This reinforces previous theories suggesting that coordinated displays signal group cohesion and strength. “Our results partially replicated previous research, showing that synchronous chants increased perceived formidability, supporting the coalition signalling hypothesis,” said Tiago Bortolini, PhD, a researcher at D’Or Institute for Research and Education in Brazil.
But the researchers noted that increased perceptions of formidability did not necessarily lead to greater hostility towards rival groups. While participants who strongly identified with their team and perceived a high level of threat from rival supporters were more likely to engage in hostile behaviour, the act of synchronised chanting itself did not directly provoke aggression. “Contrary to expectations, synchrony did not influence perceived threat, in-group cooperation, or out-group derogation behaviours,” Bortolini explained.
Football fans have long been known for their passionate chants, which are seen as an integral part of the matchday experience. The study sheds light on the potential psychological effects of these displays, particularly in reinforcing social bonds within fan communities. Previous research has suggested that synchronised actions can enhance group solidarity, a phenomenon seen in military drills, religious rituals, and even large-scale protests. The latest study adds to this body of work by showing that football chanting operates in a similar way, creating a sense of unity and strength among supporters.
One key aspect examined was the concept of identity fusion, a deep sense of oneness with a group. The research found that highly fused individuals who already viewed rival fans as a threat were more likely to engage in aggressive behaviour when exposed to synchronised chanting. “Individuals with a strong sense of identity fusion who felt threatened exhibited increased hostility toward outgroups, even at a personal cost, independent of synchrony,” Bortolini noted. This suggests that existing perceptions of threat play a more significant role in fueling hostility than the act of chanting itself.
The study’s authors believe the findings could have implications for understanding intergroup relations beyond football. In contexts where synchronised behaviour is common, such as political rallies and social movements, similar psychological effects may be at play. However, the researchers caution that the results should not be overgeneralised. “Future research should further explore and clarify the construct of perceived formidability by identifying which specific components are influenced by synchronous displays,” Bortolini added.
The study was conducted in an online setting, which may not fully capture the dynamics of real-world fan interactions. “Investigating how real-world synchrony demonstrations influence immediate threat perceptions could offer valuable insights,” Bortolini suggested. Future research could explore how these effects manifest in stadium environments where emotions run high. “Exploring the underlying mechanisms by which identity fusion interacts with perceived threats to escalate intergroup hostility is critical for developing targeted interventions aimed at reducing such negative behaviours,” he added.
