Group psychology

The branch of psychology that studies how an individual’s behavior, thoughts, and emotions change when they become part of a group. Foundational to 20th-century propaganda, modern marketing, and contemporary identity politics — the central claim is that the grouped individual is not the isolated individual, and operates by different rules.

Sigmund Freud’s working definition (from Group Psychology and the Analysis of the Ego, 1921) is concerned with:

The individual man as a member of a race, of a nation, of a caste, of a profession, of an institution, or as a component part of a crowd of people who have been organized into a group at some particular time for some definite purpose.

The Freudian operational claim

The one Bernays would later weaponize:

A group is extraordinarily credulous and open to influence. It has no critical faculty.

Once an individual identifies with a group, they subordinate self-analysis and discerning truth-search to maintaining group cohesion. Critical capacities don’t disappear, but they go quiet in service of belonging — which leaves the group-identified individual highly susceptible to appeals that bypass conscious reasoning.

Why it works (the evolutionary frame)

Per Edward Bernays and Group Psychology - Manipulating the Masses (video): the tendency to form groups was selected for in our evolutionary past because tribal organization conferred substantial survival advantages. The pull toward group identification is therefore not a cultural artifact but a deep behavioral default — even when modern technology has obviated most of the original survival rationale.

Bernays adds the personal motivation:

The individual senses the potential power of the group and derives feelings of potency in identifying with it.

The wolf pack metaphor: individuals derive an enlarged sense of self-importance from membership in a potentially powerful mass. The group is, psychologically, an amplifier of the individual self.

Bernays’s crucial refinement: a crowd is a state of mind

From Crystallizing Public Opinion:

A crowd does not mean merely a physical aggregation of a number of persons. The crowd is rather a state of mind.

This matters enormously for mass communication. Once group identification is established, the individual remains in the crowd’s mental orbit even when physically alone — at home, online, in private. Modern media exploits this by making the group’s presence continuously available in the head.

The manipulation pathway (Freud → Bernays)

Two Freudian theses combined make mass manipulation tractable:

  1. Suppressed desire: behavior is often driven by unconscious symbolic substitution, not by the conscious reasons people give. (See Propaganda.)
  2. Group credulity: in groups, critical introspection weakens.

Combined: appeals targeting suppressed desire land hardest on the group-identified individual, who cannot apply the critical filter that might catch them if reasoning alone. This is the operational core of Bernays’s career.

The political stakes (Neumann coda)

The video closes by citing Erich Neumann’s The Origins and History of Consciousness: the capacity for individual consciousness is a recent developmental achievement. Most of human history featured group-consciousness as the default; the autonomous individual is a fragile state that group identification can regress.

The individual was not an autonomous individualized entity with a knowledge, morality, volition, and activity of its own. It functioned solely as a part of the group, and the group with its superordinate power was the only real subject. (Neumann)

The political implication is that liberal-democratic societies — which presuppose individual rights and personal liberties — depend on a population capable of treating itself and others as individuals first. Mass group identification undermines that precondition.

Freud’s own version of the prescription:

Each individual has a share in numerous group minds — those of his race, his class, his creed, his nationality, etc. — and he can also raise himself above them to the extent of having a scrap of independence and originality.

Modern instances

  • Identity politics of all stripes — race, gender, nationality, class, religion, political-party — operate as group-identification engines and inherit the Freudian credulity property.
  • Online communities and tribes make Bernays’s “state of mind” formulation literal — group membership is now algorithmically reinforced 24/7 via feeds.
  • Consumer brand tribes (Apple vs. Android, Marvel vs. DC, etc.) operate on the same machinery in a lower-stakes register.
  • The persuasion principle Unity (Cialdini’s 2021 addition) operationalizes a small-scale, individual-application version of the same group-identification engine in a one-on-one setting.
  • Sigmund Freud — formalized the credulity-of-groups thesis
  • Edward Bernays — built the mass-manipulation application
  • Propaganda — the practical discipline
  • Divide and conquer — what hostile group-identification enables at the political scale
  • Unity — the analogous mechanism at the small-scale persuasion register
  • Commitment and consistency — adjacent: group-identified individuals defend group positions consistently once stated
