Group Polarization
James Stoner, Serge Moscovici, Cass Sunstein
Groups develop properties no individual has. The node crystallizes into something with its own trajectory.
Stoner (1961) — The Risky Shift
James Stoner (MIT, unpublished Master's thesis, 1961) discovered that groups consistently make riskier decisions than the average of their individual members' pre-discussion preferences. This was initially called "the risky shift" and was treated as a curiosity.
Moscovici & Zavalloni (1969) — Group Polarization
Serge Moscovici (Paris) and Marisa Zavalloni showed that the risky shift was not about risk specifically — it was a general phenomenon. Groups move toward the extreme of whatever direction the members already leaned. If individuals were slightly cautious, the group became very cautious. If slightly aggressive, the group became very aggressive.
They named this group polarization: deliberation reliably amplifies the pre-existing tendency rather than moderating it.

Sunstein (2002, 2009) — The Law of Group Polarization
Cass Sunstein (Harvard Law, later Obama administration) formalized this as a general law and demonstrated its consequences: "Deliberation tends to move groups, and the individuals who compose them, toward a more extreme point in the direction indicated by their own predeliberation judgments."
His key findings: People opposed to the minimum wage become more opposed after discussing it with like-minded others. People who support gun control become enthusiastic supporters after group discussion. People concerned about climate change become insistent on severe measures after deliberation.
The mechanism is not persuasion by argument. It operates through social comparison (people adjust toward perceived group norm) and through the skewed argument pool (in a like-minded group, most arguments point one direction).
In Going to Extremes (2009), Sunstein extended this to radicalization: when like-minded groups are isolated and feel marginalized, they share grievances, and the polarization mechanism accelerates.
Key Findings
- •Deliberation reliably amplifies the group's pre-existing tendency rather than moderating it — groups become more extreme versions of their initial lean.
- •The mechanism is social comparison and skewed argument pools, not rational persuasion — the polarization operates below conscious deliberation.
- •Isolation accelerates the process: when like-minded groups have no exposure to competing signals, the pattern intensifies unchecked.
- •No individual in the group holds the extreme position the group arrives at — the node produces emergent properties beyond any member.
What This Proves for the Framework
The node generates properties beyond its members. No individual in the group holds the extreme position the group arrives at. The group — the node — produces something none of its members brought. This is the egregore crystallizing: an emergent pattern with its own trajectory.
The script is written by the pattern, not the people. Each individual thinks they are reasoning independently. The polarization happens through mechanisms below conscious deliberation — social comparison and skewed argument pools. The egregore is operating through them, and they experience its conclusions as their own.
Isolation accelerates the process. When a group has no exposure to competing signals, the pattern intensifies faster. This maps directly to egregoric dynamics: a node without competitive egregores present moves toward its extreme unchecked.
Deliberation does not moderate — it amplifies. The rational process people trust to produce balanced conclusions does the opposite when the group shares a pre-existing lean. The egregore rides the mechanism of reason itself.
