Harold Lasswell

13 min read

Imagine a single scholar who mastered anthropology, communications, economics, law, philosophy, psychology, psychiatry, and sociology—not just dabbled in them, but made pioneering contributions to each. Harold Dwight Lasswell was that scholar, a "one-man university" whose work in the early and mid-twentieth century fundamentally shaped how we understand propaganda, political psychology, and the science of making better decisions.

When Lasswell died in 1978, his colleagues didn't just mourn a respected academic. Gabriel Almond, writing for the National Academies of Sciences, ranked him "among the half dozen creative innovators in the social sciences in the twentieth century." Few questioned that he was "the most original and productive political scientist of his time."

What made Lasswell extraordinary wasn't just his breadth—it was his refusal to respect the boundaries between disciplines. He didn't see himself as a political scientist who occasionally borrowed from psychology or a psychologist who studied politics. He actively worked to erase the lines dividing these fields, believing that understanding human behavior required drawing on every tool available.

The Making of a Polymath

Lasswell's journey began in Donnellson, Illinois, where he was born on February 13, 1902, to a clergyman father and a school teacher mother. An older brother had died in childhood, leaving Harold as an only child.

Even in high school, his trajectory was clear. He edited the school newspaper and delivered the valedictory speech at graduation. But his real education came from two unlikely mentors: his uncle, a physician who introduced him to Sigmund Freud's revolutionary ideas about the unconscious mind, and an English teacher who handed him the works of Karl Marx and Havelock Ellis.

These weren't casual reading assignments. They planted seeds that would grow throughout his career—questions about how power works, how sexuality and psychology intersect with politics, and how human desires shape social structures.

Excelling in history and English, Lasswell won a scholarship to the University of Chicago. He arrived in 1918, just sixteen years old, as World War I was ending and the world was grappling with the power of wartime propaganda.

Decoding Propaganda

By age twenty-five, Lasswell had completed a doctoral dissertation that would change how we think about persuasion. "Propaganda Technique in the World War," published in 1927, defined propaganda as "the control of opinion by significant symbols"—stories, rumors, reports, pictures, any form of social communication designed to shape what people think.

This might sound obvious now, but it was groundbreaking then. Lasswell wasn't just cataloging propaganda techniques. He was arguing something radical: propaganda is unavoidable, and democracies must adjust to it rather than fight it.

Think about that for a moment. He wasn't saying propaganda is always evil or that we should ban it. He was saying it's a fundamental feature of modern society, and we need to understand how it works.

His definition went further: propaganda is "concerned with the management of opinions and attitudes by the direct manipulation of social suggestion." Notice the word "management." Lasswell recognized that propaganda doesn't just change what you think—it changes what you do. It's not passive information; it's active influence.

The Institute for Propaganda Analysis later built on his work, defining propaganda as "the expression of opinions or actions carried out deliberately by individuals or groups with a view to influence the opinions or actions of other individuals or groups for predetermined ends through psychological manipulations."

That's a mouthful, but it captures something crucial: propaganda is intentional, targeted, and designed to achieve specific goals through psychological means rather than logical argument or physical force.

Inventing Content Analysis

Studying propaganda led Lasswell to a problem: how do you systematically analyze communication? You can't just read newspapers and speeches and say, "Yep, that's propaganda." You need a method.

So he invented one. Content analysis—the systematic study of communication documents to examine patterns—became one of his most lasting contributions.

In 1935, Lasswell published "World Politics and Personal Insecurity," using quantitative content analysis to study international relations. He didn't just read diplomatic cables and guess at their meaning. He standardized how information was collected, developed categories for analysis, and used quantitative measurements to identify patterns.

During World War II, this became crucial. Lasswell contributed to a wartime communications project sponsored by the Library of Congress, producing what scholars consider "one of the most comprehensive single content analysis study ever undertaken with scholarly objectives." That work, "Language of Politics: Studies in Quantitative Semantics," showed how systematic analysis could reveal hidden patterns in political communication.

Here's what made his approach powerful: instead of relying on intuition or cherry-picked examples, content analysis let researchers count things, track changes over time, and test hypotheses about communication effects.

But it had limits. The main criticism? Content analysis can tell you what messages say, but not what they do. You can count how many times a newspaper mentions "freedom" or "security," but that doesn't tell you whether readers care or how it changes their behavior. Lasswell acknowledged this weakness—you can make inferences about data, but verifying those inferences requires other methods.

Five Questions That Changed Communication Study

In 1948, Lasswell published a model that became one of the most influential frameworks in communication studies. He reduced the entire communication process to five questions:

Who says what to whom in what channel with what effect?

That's it. Every act of communication can be analyzed by asking those five questions. Who is the sender? What is the message? Who is the receiver? What medium carries it? And what happens as a result?

This became known as Lasswell's five-questions model, and it organized "the scientific study of the process of communication" for decades. Researchers used it to structure investigations: study the communicator (who), analyze the content (what), identify the audience (to whom), examine the medium (what channel), and measure the outcome (with what effect).

Of course, scholars eventually criticized its simplicity. It's linear—message goes from sender to receiver, end of story. There's no feedback loop, no accounting for noise or interference, no consideration of context. Communication isn't a one-way street; it's a complex dance where everyone influences everyone else.

But even critics acknowledged its power as a starting point. Sometimes the most useful tools are the simplest ones.

The Garrison State

In 1941, Lasswell published an article in the American Journal of Sociology that introduced a chilling concept: the garrison state.

He was writing as World War II raged, and he saw a disturbing possibility. What if modern warfare pushed nations toward a new form of government—not traditional dictatorship, not democracy, but something else? A state dominated by "specialists in violence," a political-military elite that controlled society in the name of perpetual security.

This wasn't science fiction. Lasswell was extrapolating from trends he observed: the militarization of society during wartime, the rise of permanent military establishments, the increasing importance of technology and expert knowledge in warfare.

The garrison state was a "developmental construct"—a model of where things might go if certain trends continued. It became hugely influential in debates about national security, civil liberties, and the relationship between military power and democratic governance.

Think about post-9/11 America—the expansion of surveillance, the permanent war footing, the elevation of military and intelligence experts in policy debates. Lasswell's concept gave scholars a framework to analyze those developments.

Founding Political Psychology

Lasswell didn't just study what politicians said. He wanted to understand why they acted the way they did—what psychological drives and unconscious motivations shaped political behavior.

This led him to become, in the 1930s and 1940s, the founder of political psychology, the intersection of psychology and political science. His key insight came from Freud: human behavior isn't purely rational. We're driven by instinctual urges we don't fully understand, and our perspectives are malleable, shaped by unconscious forces.

Lasswell studied with Theodor Reik, a devoted follower of Freud, in Vienna and Berlin. He learned psychoanalytic methods and brought them back to the University of Chicago, where he built a laboratory in his social science office to conduct experiments on volunteers and students. He also studied with Elton Mayo at Harvard, learning interviewing and recording techniques that he adapted for political research.

His psychoanalytic biographies of political leaders broke new ground. Instead of treating leaders as pure rational actors, he examined their psychopathology—how childhood experiences, neuroses, and unconscious conflicts shaped their wielding of power.

His books "Psychopathology and Politics," "World Politics and Personal Insecurity," and "Power and Personality" introduced Freudian theory to social science. In "Politics: Who Gets What, When, How," he framed politics as fundamentally about power—who has it, who wants it, and how they get it. He saw elites as the primary holders of power, a view that influenced generations of political scientists.

Creating the Policy Sciences

Lasswell wasn't content just to understand the world. Like his philosophical predecessor John Dewey, he believed knowledge should solve public problems.

This led him, from the 1950s through the 1970s, to help create the policy sciences—an interdisciplinary movement to integrate social science knowledge with public action. He wasn't just asking "What do we know?" He was asking "How do we use what we know to make better decisions?"

In 1944, Lasswell, along with colleagues Myres McDougal and George Dession, created the Policy Sciences Council. In 1948, they established the Policy Sciences Foundation. These weren't just academic clubs. They were institutions designed to train a new kind of expert: the policy scientist.

What does a policy scientist do? Lasswell outlined it in his 1956 book, "The Decision Process: Seven Categories of Functional Analysis." He identified seven stages of policy decision-making:

Intelligence - gathering information
Promotion - advocating for alternatives
Prescription - establishing rules
Invocation - applying rules to specific situations
Application - enforcing rules
Termination - ending policies
Appraisal - evaluating outcomes

Critics complained this was too linear, too much like a simple cycle. Real policy-making is messy, with feedback loops and skipped steps. But again, the framework gave researchers and practitioners a shared language.

Lasswell also identified eight "goal values" of policy: wealth, power, respect, rectitude (moral rightness), skill, well-being, enlightenment, and affection. These weren't just abstract categories—they were the actual things people pursue through political action.

In his 1971 book, "A Pre-View of the Policy Sciences," he prioritized five "intellectual tasks" for policy scientists: clarifying goals, describing trends, analyzing conditions, projecting future developments, and providing alternative courses of action.

Notice what's missing: Lasswell didn't say the policy scientist should make the final decision. That's for democratic processes. The policy scientist's job is to provide clarity, analysis, and options.

A Career of Boundary-Crossing

Lasswell's institutional journey reflected his intellectual breadth. From 1922 to 1938, he taught political science at the University of Chicago. Then, in a remarkable pivot, he spent a year at the Washington School of Psychiatry, from 1938 to 1939, before becoming director of war communications research at the U.S. Library of Congress from 1939 to 1945.

During and after World War II, he taught at the New School for Social Research and Yale Law School. At Yale, he started as a visiting lecturer teaching a graduate seminar on "Property in a Crisis Society"—typical Lasswell, blending law, economics, and political theory. He became a full-time faculty member after the war, teaching law and political science from 1946 to 1970.

Even retirement didn't slow him down. From 1970 to 1972, he taught at the City University of New York's John Jay College. From 1972 to 1976, he was a distinguished professor at Temple University School of Law. Columbia University named him the Albert Schweitzer Professor of International Affairs.

After finally retiring from teaching in 1976, he spent his remaining years working with the Policy Sciences Center, continuing to develop the field he'd helped create.

Recognition and Legacy

The honors accumulated throughout his career. He served as president of the American Political Science Association in 1956 and president of the American Society of International Law from 1966 to 1968. He was involved with the Association for the Advancement of Science, the Commission on the Freedom of the Press, the Committee for Economic Development, and the RAND Corporation.

He received honorary degrees from the University of Chicago, Columbia University, the University of Illinois, and the Jewish Theological Seminary of America. In 1960, the American Council of Learned Societies called him a "master of all the social sciences and pioneer in each." He was elected to the American Academy of Arts and Sciences and inducted into the National Academy of Sciences in 1974.

His productivity was staggering. Over his career, he published between four and six million words—books, articles, essays, reports. That's roughly the equivalent of forty to sixty full-length books.

Ahead of His Time

In his 1956 presidential address to the American Political Science Association, Lasswell raised a question that seemed like science fiction at the time: should we give human rights to robots?

This wasn't idle speculation. Lasswell was arguing that technological innovation and the Cold War meant the nation's future was at stake. Political science needed to evolve—to provide clear goals, develop theoretical models of political processes, and create policy alternatives that maximize democratic values.

He believed political science should be practiced like law: as a free profession, not just an academic pursuit. Scholars shouldn't just publish papers for other scholars. They should engage with real-world problems, advise decision-makers, and help shape better policies.

In 1980, two years after his death, his final major work was published: "Human Rights and World Public Order," co-authored with associates. It presented a comprehensive framework for approaching international human rights law, continuing his lifelong effort to bridge theory and practice.

The End

On December 24, 1977, Lasswell suffered a massive stroke. He died of pneumonia on December 18, 1978, at the age of seventy-six.

What he left behind wasn't just books and articles. He left entire fields of study: political psychology, policy sciences, systematic content analysis. He left frameworks that researchers still use: the five-questions model, the garrison state concept, the stages of decision-making.

Most importantly, he left an example of intellectual courage—a willingness to cross boundaries, to borrow tools from any discipline that might help solve a problem, to insist that knowledge should serve human welfare.

In an age of increasing specialization, where academics often know more and more about less and less, Lasswell's career stands as a reminder that the biggest breakthroughs often come from seeing connections others miss, from refusing to stay in your lane, from asking not just "What do I know?" but "What can I do with what I know?"
