Schelling Point / Schelling Sort
A belief can coordinate people without merely describing reality: shared agreement marks affiliation, and disagreement can sort a mixed population into opposed groups.
A population can begin mixed and end up cleanly divided—not because its members acquired different interests, but because a belief gave them a line on opposite sides of which to stand.
E1Belief becomes a sorting signal
The belief acts as a shared coordination point. Once people expect others to orient around it, assent communicates more than conviction: it reveals who will align with whom. Repeated alignment then turns an initially overlapping population into distinct camps—a process described here as Schelling sort. This extends the ordinary Schelling point idea: the salient point does not merely help people converge; it can also expose incompatible affiliations and drive separation.
E1A label is not yet an explanation
The supplied material names the sorting pattern but does not establish which beliefs trigger it, how quickly division occurs, or whether belief causes the split rather than merely revealing one already present. Use the model to identify a possible coordination mechanism, not to explain every disagreement or prove that the underlying claim is false.

"The beliefs are called shelling points by economists and the process by which people cleanly separate out into two groups when they were not separate earlier is called shelling sort."
