Herbert Simon

Herbert Simon appears in The Wisdom of Crowds not as a participant in a narrated personal biography but as an intellectual reference point for the book’s account of how people think, learn, and decide. His concept of bounded rationality names a basic human limitation: people have less information than they would like, limited foresight, and neither the ability nor the inclination to calculate every choice comprehensively. They often settle for what seems good enough, and emotion can shape their judgments. Yet those limitations do not rule out good collective decisions. When individual judgments are aggregated under the right conditions, the result can be remarkably intelligent.

Bounded Rationality and Collective Judgment

Simon’s idea helps frame the contrast at the heart of the book. The intelligence of a group does not require every member to be exceptionally informed or rational, nor does it depend on putting a few brilliant people in command. Individuals make imperfect judgments, but a suitable process can bring those judgments together into a result better than any one person’s. The claim is not that individual limitations disappear; it is that collective judgment can compensate for them.

That account also sets a boundary on what can be inferred from the success of a group. Collective intelligence is conditional, not automatic. The book stresses the circumstances in which judgments are combined, particularly the preservation of different perspectives and some independence among members. Simon’s bounded rationality thus belongs to an argument about both the limits of individual decision-makers and the possibility of organizing those limits productively.

Expertise Has a Narrow Reach

The book’s discussion of expertise gives that argument a sharper edge. A chess expert, as described through work by Simon and W. G. Chase, can reproduce the arrangement of a game in progress from memory, while an amateur cannot. But the expert loses that advantage when the chess pieces are placed irregularly and haphazardly. Expertise reflects deeply learned patterns within a particular domain; it does not establish a general capacity to solve any problem.

This example distinguishes genuine skill from the broader authority often attached to expertise. The chess player’s exceptional memory is real, but its strength depends on a meaningful chess position. The book uses the contrast to challenge the assumption that intellectual excellence transfers freely from one field to another. Drawing on Chase’s characterization, it presents expertise as “spectacularly narrow.” Simon’s place in this argument is therefore not a rejection of expertise, but a reminder that specialized mastery does not by itself confer universal judgment.

Organizations Shape What People Know

Simon’s account of organizational life supplies the social counterweight to the idea that individuals form judgments independently. A person does not spend months or years in a particular organizational position, exposed to some channels of communication and shielded from others, without those conditions profoundly affecting what that person knows and believes. The position also shapes what receives attention, what is feared or hoped for, and what is proposed.

The observation complicates the assumption that people arrive at their preferences in isolation. The book contrasts the economic emphasis on autonomy with sociological accounts of people embedded in social contexts, where influence is unavoidable. Simon’s statement makes the organization itself part of the explanation: communication is not merely a channel for passing information but a force that shapes the judgments people can make.

Imitation as an Economy of Effort

Simon also connects imitation to the limits of individual knowledge. Because no one can know everything, people can specialize in finding information while others learn by copying what they do. Imitation spreads the benefit of someone’s effort without requiring everyone to repeat the same investigation, and information can travel through a system without direction from a central authority.

The book presents this as a practical response to cognitive limits rather than as an unconditional virtue. People remain willing to imitate only while the practice proves effective; bad information and its consequences can prompt them to learn for themselves. Simon’s speculation that humans may be genetically predisposed to be imitation machines extends the point beyond deliberate calculation. Imitation can make limited knowledge useful across a group, but the wider account of independence supplies a necessary qualification: when people take cues from one another, they may also converge on the same beliefs and repeat the same mistakes.

The Tension Between Social Learning and Independence

Simon’s ideas illuminate a tension rather than offering a simple rule. Learning from others distributes knowledge and reduces the burden each person must carry alone; organizational communication and social contact, however, can also make members’ judgments dependent on one another. If influence causes people to share the same assumptions, their mistakes become correlated, and a group may become collectively less intelligent even as its members learn more from one another.

The distinction is between social learning that spreads useful information and influence that erases independent judgment. Imitation can be efficient, and bounded individuals have good reason to rely on what others know. But the book’s account of collective intelligence depends on maintaining enough diversity and independence for people to contribute different information and perspectives. Simon’s role is to make that balance intelligible: individual cognition is limited, socially shaped, and capable of improvement through shared practices, yet the wisdom of a group depends on how those practices preserve or undermine the differences among its members.
