Joan Westenberg’s ‘The Loop’ Endures—But History Is Not Biologically Guaranteed

Four months after Joan Westenberg published “The Loop,” the essay remains available and its central warning is still easy to recognize: societies repeatedly produce bubbles, strongman politics, scapegoating and panic. The essay dated April 27, 2026 attributes those recurrences to cognitive equipment that changes much more slowly than institutions and technology.

That framing is still useful, particularly when a new market or political movement insists that old comparisons no longer apply. But the strongest literal version of Westenberg’s thesis—that an effectively unchanged human “operating system” guarantees repetition—goes beyond what the evidence cited here can establish. Current research describes humans as both evolutionarily constrained and unusually capable of changing behavior through learning, culture and institutions.

What “The Loop” actually argues

Westenberg does not merely observe that historical episodes resemble one another. Her deeper claim is causal: recurring outcomes arise from durable features of human cognition, while ideologies, governments and technologies are comparatively fast-changing applications running on that older biological machinery.

The essay develops that proposition across several domains. Speculative booms reward imitation and optimism; uncertainty increases the appeal of decisive authority; social distress creates demand for an identifiable enemy; and unfamiliar media provoke promises, rapid adoption and later moral alarm. The actors and instruments change, but the incentives and emotional reactions appear familiar.

This breadth is the essay’s greatest strength. It invites readers to compare events normally kept in separate compartments—finance, war, political power, technology and collective blame—and to ask whether the same behavioral tendencies are operating beneath different language and institutions.

The title’s certainty is the vulnerable part

Similarity is not the same as inevitability. Selecting episodes with comparable arcs can reveal a valuable pattern, but it cannot by itself demonstrate that the pattern must recur, determine its interval or show that biology is the decisive cause. Different mechanisms may produce superficially similar outcomes, while cases in which institutions prevented escalation are less dramatic and therefore easier to overlook.

There is also a gap between saying that humans inherit recurring tendencies and saying that the resulting history is fixed. Fear, conformity, status-seeking and short-term reward sensitivity can influence decisions without dictating one unavoidable political or economic outcome. Laws, professional norms, education, incentives and collective memory all alter which tendencies are rewarded, restrained or redirected.

For that reason, “guarantees” is best read as the essay’s rhetorical provocation, not as a demonstrated scientific conclusion. Westenberg’s argument becomes more defensible when recast this way: durable human tendencies create recurring risks, especially when institutions fail to counter them.

Research adds flexibility to the operating-system metaphor

A 2024 evolutionary model in Nature Communications directly challenged the assumption that social-learning strategies are immutable. The authors found that uncertain benefits can favor developmental programs that adjust reliance on other people’s behavior according to experience; the model’s central result was evolved flexibility, not one uniform response shared by every person or population.

This does not disprove Westenberg’s catalogue of recurring mistakes. It does show why the computer metaphor has limits: inherited capacities can include the ability to update behavior, not merely fixed instructions that reproduce the same error. The same social-learning machinery that spreads enthusiasm or prejudice can also transmit warnings, safeguards and better practices.

A second qualification comes from research on the range of human culture. Morgan and Feldman argue that its distinguishing feature is its open-ended scope of heritable variation, after comparing human culture with animal culture and other inheritance systems. Their 2025 Nature Human Behaviour perspective therefore presents culture as an adaptive system capable of generating extraordinarily varied outcomes, rather than a thin application layer with little power over behavior.

Why the essay remains useful

“The Loop” works best as an alarm, not a forecasting engine. It cannot tell a reader whether a particular asset is in a bubble, whether a leader will dismantle institutions or whether concern about a technology is disproportionate. Those judgments still require case-specific evidence, competing explanations and attention to conditions that differ from earlier episodes.

What the framework can do is identify moments that deserve greater scrutiny. A claim of permanent prosperity, a movement built around one indispensable leader, a complex failure blamed on a vulnerable group, or a technology marketed as exempt from earlier trade-offs should trigger questions before certainty hardens into consensus.

The practical value lies in slowing down interpretation. Readers can ask which earlier case genuinely shares the same mechanism, which important conditions have changed, what evidence would falsify the analogy and which institutions are capable of interrupting the apparent sequence. Those questions preserve Westenberg’s warning while reducing the risk of treating every resemblance as proof.

The loop is a risk pattern, not a verdict

Westenberg’s essay remains compelling because it confronts the recurring confidence that a new era has escaped old human weaknesses. Its historical sweep makes complacency harder, and its repeated emphasis on recognizing the pattern from inside it gives readers a concrete intellectual task.

Yet human nature does not supply a calendar for crashes, dictatorships or moral panics. Biology shapes the range of possible behavior; experience, culture and institutions help select among those possibilities. History can echo because familiar incentives and vulnerabilities return, but neither the echo nor its outcome is guaranteed.

The most durable reading of “The Loop,” then, is less fatalistic than its headline. Assume that recurring human tendencies are real enough to demand safeguards, but remain alert to the equally human capacities for learning, institutional design and cultural change. Recognition matters precisely because repetition is a danger that can sometimes be delayed, softened or avoided—not an outcome already written into the brain.
