PART II – FROM BELONGING TO DIVISION
Question 6
The tipping point: when cohesion becomes hostility
Belonging can be warm, cooperative and harmless. But under some conditions, the boundary around “us” begins to harden — and the people beyond it start to look threatening.
What turns another group into an enemy?
Groups do not become hostile for one simple reason.
Competition over resources can matter. So can fear, humiliation, inequality, historical grievance, political leadership, propaganda and the belief that another group’s gain must become our loss.

Hostility can become self-reinforcing.
One threatening act changes expectations. Suspicion makes defensive behaviour seem necessary. That behaviour is then interpreted as aggression by the other side — giving both groups new reasons to distrust one another.
The same people can therefore become trapped in very different social worlds: one built around trust, another around threat.
This is where the problem becomes more dangerous for Beyond Tribes:
What pushes ordinary rivalry across the threshold into hatred — and can that process be interrupted before it becomes self-sustaining?
The questions we want to explore
- Why do some group differences remain harmless while others become threatening?
- When does scarcity create conflict, and when can people cooperate under pressure?
- How do humiliation, grievance and fear turn competition into hostility?
- Why can leaders benefit from activating divisions that previously mattered little?
- How do rumours, propaganda and hostile acts create spirals of mistrust?
- Can societies recognise the warning signs early enough to reverse the process?

The enemy may not appear all at once. Sometimes hostility grows through a chain of small changes until each side begins to see the other’s fear as proof of its own.
