Efforts to change strongly held opinions often hit a wall. Push too hard, and people tend to dig in further, making consensus even harder to achieve. But a new study suggests a counterintuitive approach: instead of trying to convert opponents, it may be more effective to encourage them to step back and remain neutral.
Researchers at the University of Bath, led by mathematician Professor Kit Yates, have found that creating space for neutrality — such as allowing people to abstain rather than choose sides — can make groups more flexible and open to change. Their findings, published in Advanced Science, point to a quieter but more effective path to shifting group opinion.
The idea is simple. When individuals are not forced into binary positions, they gain room to reassess their views. This “breathing space,” as the researchers describe it, can make it easier for a group to gradually move toward consensus or adapt when circumstances change.
Yates argues that neutrality should not be seen as indecision or weakness, but as a useful feature of how groups function. According to the study, once neutrality is allowed, even basic one-on-one interactions — where one person influences another — can lead to meaningful shifts in collective opinion without the need for complex social dynamics.
To understand this, the researchers built a mathematical model of group decision-making. It revealed two distinct pathways to consensus. The first is familiar: persuading undecided individuals to pick a side. The second, less explored route involves “de-escalation,” where disagreement pushes individuals into a neutral position before they later adopt a stance independently.
This second pathway turned out to be particularly powerful. When more people move into a neutral state, the number of active decision-makers shrinks. As a result, small influences or random shifts carry more weight, allowing a new consensus to emerge more quickly.
The team tested this theory beyond models, looking at both animal behaviour and human decision-making.
In swarms of locusts, they observed that when the group changes direction, it first goes through a brief pause. Many locusts stop moving altogether, effectively becoming neutral. During this moment, only a small number remain active, and their movements disproportionately shape the swarm’s new direction. This temporary pause amplifies small changes, helping the group realign بسرعة.
Human experiments showed a similar pattern. In voting-based games, groups that were given the option to abstain shifted their decisions more smoothly and quickly than those forced to choose between fixed options.
The implications extend well beyond the lab. From corporate boardrooms to online debates, the findings suggest that reducing intensity — rather than escalating persuasion — may be key to breaking deadlocks. Encouraging strongly opposed individuals to adopt a neutral stance, even temporarily, could help groups reset and move forward.
Co-author Professor Tim Rogers notes that while fence-sitting is often seen as frustrating, it may actually play a constructive role. By easing tension and reducing polarisation, neutrality can create the conditions needed for more responsive and adaptive decision-making.
In a world increasingly defined by sharp divisions, the study offers a subtle but important insight: sometimes, the fastest way to change minds is not to push harder, but to allow people the space to pause.
