From Opinion to Extreme Action: What Drives Political Engagement 2026

What turns an opinion into action—and when does that action become extreme? For Professor Emma Thomas, a social psychologist at Flinders University, this question is central to understanding political engagement and extremism. With over 20 years of research, she notes that almost every news story involves some form of collective action, from protests to grassroots campaigns. Her work sheds light on why people mobilize and how peaceful participation can sometimes shift toward confrontation.

Thomas emphasizes that being engaged and taking action are not inherently problematic. “Protests, advocacy and political participation are really signs of a healthy democracy,” she says. “These are good things. Concerns arise when people become willing to use coercion, intimidation, violence or deliberate manipulation to achieve political ends.” This distinction is crucial: action is normal, but extremism emerges when tactics cross into harm.

Why Collective Action Is on the Rise

People are increasingly coming together to change their world, sometimes peacefully and sometimes confrontationally. Thomas observes that mobilization often follows crises or perceived injustices. The rise of social media and global connectivity has made it easier for like-minded individuals to organize and amplify their voices.

However, the line between constructive advocacy and destructive extremism is not always clear. Thomas’s research aims to map the psychological and social factors that push individuals from holding an opinion to taking extreme actions. Understanding these pathways is essential for fostering healthy democracy while preventing violence.

The Landmark Study Tracking 5,000 Australians

Under an Australian Research Council Future Fellowship, Thomas and her team are conducting a four-year longitudinal study. They are following 5,000 Australians, surveying them every six months to track changes in attitudes and behaviors over time. By mapping these shifts against life events and circumstances, the researchers hope to identify triggers for extreme engagement.

This study is unprecedented in its scope, providing real-time data on how political views evolve. It will help pinpoint when and why individuals might adopt coercive tactics. The findings could inform policies and interventions to support constructive engagement and counter extremism.

Key Factors That Drive Action

• Perceived injustice: A strong sense of unfairness can motivate people to act.
• Social identity: Group belonging and shared grievances fuel collective action.
• Efficacy: Belief that action can make a difference increases participation.
• Emotional arousal: Anger and fear can push individuals toward confrontation.
• Social networks: Connections with activists can normalize extreme tactics.

When Does Action Become Extreme?

Extremism arises when people justify coercion, intimidation, or violence for political ends. Thomas notes that this shift often occurs gradually, influenced by escalating rhetoric, polarization, and a sense of threat. The longitudinal study will track these transitions, offering insights into early warning signs.

Importantly, the research does not pathologize activism. Instead, it distinguishes between healthy participation and harmful extremism. By understanding the drivers, society can better support democratic engagement while mitigating risks.

Implications for Policy and Society

The findings will be valuable for policymakers, educators, and community leaders. They can inform strategies to promote constructive dialogue and address grievances before they escalate. Thomas’s work underscores the need for inclusive institutions that channel dissent into peaceful change.

As political polarization grows globally, this research offers a timely framework for safeguarding democracy. It highlights that engagement is not the enemy—extremism is. By fostering trust and addressing root causes, societies can encourage participation without violence. The background to this story is set out in India's Gen Z Collective Action Power: A Democratic Awakening. A related thread runs through India's Gen Z Collective Action: A New Era of Protest. Earlier coverage in India's Gen Z Collective Action Sparks Democratic Reform Movement shows how the argument developed.

What to Watch Next

The study will continue to collect data over four years, revealing patterns and risk factors. Thomas hopes to identify interventions that steer individuals away from extremism. Future publications will share actionable insights for building resilience against radicalization.

The same theme surfaces in Scottish Island Discovery Sheds Light on Christianity Spread, which takes a different angle.

For now, the message is clear: collective action is a sign of democratic health, but vigilance is needed to prevent it from turning destructive. Understanding the journey from opinion to extreme action is a step toward a safer, more engaged society. Context on how this played out before sits in Farage's Clacton: Optimism Deficit Drives Political Cynicism. A companion piece, Guyana's Post-Slavery Collective Action: Lessons in Economic, approaches the same subject from another angle.
