The psychology of peoples and crowds examines how shared ideas, norms, and experiences influence people’s behavior in groups. Its origins lie in efforts to understand collective life; its limits stem from the fact that neither a “people” nor a “crowd” has a single character or erases differences between individuals.
How do collective beliefs emerge, and why does a group sometimes behave differently from its members acting alone? In exploring these questions, it is important to distinguish useful explanatory models from generalizations that turn diverse people into a supposedly unified whole.

What does “the psychology of peoples and crowds” mean?
“The psychology of peoples and crowds” is a general term for two distinct research traditions: the historical “psychology of peoples,” which studied the collective psyche through language, myths, customs, and social life, and the “psychology of crowds,” which examines how people behave in assemblies, crowds, and movements.
The “psychology of peoples” sought to explain how shared ways of life are connected to people’s ideas and habits. Its subject matter included folk myths and customs, for example; this approach cannot be reduced to measuring the supposedly unchanging character of an entire people.
The “psychology of crowds” focuses on how people interact in a group: how emotions, imitation, and shared beliefs may spread. Taken together, these terms do not form a single modern theory: they encompass different questions and research traditions. For general context, see our explainer “Psychology and Education: Key Fields, Concepts, and Applications.”
How did ideas about the psychology of peoples and crowds emerge?
From cultural history to the crowd
Ideas about the psychology of peoples and crowds emerged from attempts to understand how shared ideas take shape over time and how people behave in a crowd. In the 19th century, philosophers and researchers turned to language, myths, and customs, viewing them as keys to collective experience. The German concept Volksgeist — “national spirit” — expressed a philosophical idea, not the result of standardized psychological measurement.
In 1895, the French author Gustave Le Bon published The Psychology of Peoples and Crowds, linking crowd behavior to suggestion and emotional contagion. Thus, one title brought together two scales of inquiry: the ideas of a people that take shape over time and the behavior of people in a crowd. Le Bon’s work became part of the history of these ideas, but its conclusions should not be treated as the results of standardized measurement.
Nineteenth-century works are best read as historical sources: their generalizations about peoples and crowds often need to be scrutinized. At the same time, it is useful to distinguish between two approaches:
- Volksgeist: a philosophical idea of collective experience expressed through language, myths, and customs.
- Le Bon, 1895: an account of crowd behavior in terms of suggestion and emotional contagion.
How does the psychology of crowds differ from the psychology of peoples?
The psychology of peoples studies long-term cultural processes, while the psychology of crowds examines people’s behavior in a specific situation. For the former, the subject of analysis might be language, traditions, collective memory, or a shared ritual; for the latter, it might be how people interact at an assembly and how a response spreads through the group.
What exactly is being compared?
The psychology of peoples considers cultural practices in their historical context: for example, a shared ritual as a repeated action that sustains a tradition and passes it on to participants. The psychology of crowds focuses on what is happening here and now — people’s responses at an assembly, their interactions, and the influence they have on one another’s behavior.
- Psychology of peoples: the unit of analysis is a language, tradition, collective memory, or ritual connected to a long-term cultural process.
- Psychology of crowds: the unit of analysis is the participants in a particular assembly, their interactions, and how a response spreads through the group.
Similar behavior among people in a single crowd does not, in itself, prove that they share a national trait: the situation, rules, goals, and makeup of the group may all influence it. To assess a conclusion, ask: does it describe an observed group in a specific context, or does it attribute a quality to all members of a people? In the latter case, observing one crowd is not enough to support such a generalization.
How can collective behavior be studied without stereotypes?
From labeling to description
Collective behavior can be studied without stereotypes by specifying who acted, where, and under what circumstances, and by separating the observed action from assumptions about its motive. Rather than saying “a people,” describe a specific group and situation: for example, people attending an assembly in a particular place or people performing the same action in response to a specific event.
The same action does not, by itself, prove that people hold the same beliefs: they may be following a shared rule, responding to circumstances, or pursuing different goals. That is why a conclusion should be checked against observable actions and compared with other situations involving the same people or groups. If a practice recurs in different circumstances, there is more reason to consider it persistent; if it has been observed only in one episode, the conclusion should be limited to that episode.
How to assess a conclusion
A testable description names the practice and the conditions under which it was observed, and allows for the possibility that new observations could disprove it. To do this, it is useful to record:
- who exactly took part and where the action took place;
- what situation preceded the action and what exactly was observed;
- whether the same practice appears in other situations or the conclusion is based on a single event.
The phrase “this culture always acts this way” specifies neither the group nor the conditions, and gives no indication of what observations might disprove it. A precise description limits the conclusion to what was actually observed and leaves room to revise it when other examples emerge.
When do generalizations about peoples become erroneous?
Generalizations about peoples become erroneous when the actions of individuals are attributed to an entire nationality or culture without evidence of a connection. One person does not represent millions of others: their behavior may be explained by personal experience, the rules of a particular situation, and their own interests. If these factors have not been examined, nationality becomes a label rather than an explanation.
Three warning signs of overgeneralization
When someone reasons about a collective character, the words “everyone,” “always,” and “by nature” should raise concern: they present a historically changing practice as an unchanging trait. You can check such a claim by asking what time period, circumstances, and specific behavior it refers to. Without those boundaries, a general conclusion cannot be reliably applied even to the group being described, let alone to an individual.
- “Everyone” extends the behavior of individual participants to an entire nationality without evidence.
- “Always” erases differences between historical periods and circumstances.
- “By nature” presents a changeable practice as an innate, unchanging trait.
Ideas about collective character can be studied as part of the history of thought, but using them to diagnose a particular person is dangerous. A ready-made stereotype substitutes for examining rules, circumstances, and interests, and then becomes a justification for prejudice: rather than judging a person’s actions in context, it judges them by an identity ascribed to them.
What can the psychology of peoples and crowds explain today?
Today, the psychology of peoples and crowds can help us ask how emotions spread in a specific situation, what role shared symbols play, and how group influence changes behavior. A historical concept can serve as a starting point for analysis, but on its own it does not prove why this particular group acted in this particular way.
How to limit a conclusion
When analyzing a crowd event, it is important to distinguish observed behavior — such as people taking part in a shared action — from claims about supposedly innate traits of a people. Such claims cannot be supported simply by the fact that participants belong to the same culture: the situation and the specific group must also be taken into account.
A sound conclusion therefore relates to a particular event, its participants, and its context, not to everyone who belongs to a culture. Concepts such as emotions, symbols, and group influence help frame questions; answering them requires examining specific circumstances rather than turning a historical theory into a universal explanation.

Key takeaways
- Gustave Le Bon’s book The Psychology of Peoples and Crowds was published in 1895.
- Volksgeist is a historical concept, not a measured psychological indicator.
- A group’s behavior in a specific situation does not prove that a people has unchanging traits.
- The words “everyone” and “always” are reasons to check whether an observation has been turned into a stereotype.
