The claim that the 1938 radio broadcast of The War of the Worlds set off a nationwide panic is one of the most repeated stories in the history of mass media. It appears in textbooks, documentaries and anniversary articles as proof of the power of broadcasting to deceive. The broadcast was real, and some listeners were genuinely frightened. But the picture of millions of Americans fleeing their homes, jamming highways and arming themselves against Martians is badly exaggerated. Much of that picture was created by newspapers the next morning, and the story has been retold so often that it has become a myth about misinformation that is itself misinformation.

The claim

In its familiar form, the story runs like this. On the evening before Halloween in 1938, the Mercury Theatre on the Air, led by 23-year-old Orson Welles, broadcast an adaptation of H. G. Wells's novel on the CBS radio network. The program was written as a series of realistic news bulletins interrupting a dance-music program, reporting a Martian landing at Grover's Mill, New Jersey. Listeners who tuned in late, the story goes, missed the announcement that it was a drama, believed the invasion was real and panicked. People fled into the streets with wet towels over their faces to protect themselves from poison gas, churches filled with people praying, and hospitals treated people for shock.

The broader lesson drawn from the story is that mass media can make an entire population believe almost anything. That lesson is repeated today in discussions of social media, deepfakes and viral hoaxes.

Origin

The panic narrative began on the morning of October 31, 1938. The New York Times ran the front-page headline "Radio Listeners in Panic, Taking War Drama as Fact." Hundreds of other newspapers carried similar stories, many relying on wire-service reports and a handful of anecdotes. Reporters described people fleeing, calling police stations and newspaper offices, and in a few cases suffering injuries.

The story gained scientific authority in 1940, when the Princeton psychologist Hadley Cantril published The Invasion from Mars: A Study in the Psychology of Panic. Cantril estimated that about six million people had heard the broadcast and that about 1.2 million had been frightened or disturbed by it. That estimate became the basis for decades of retelling.

What the evidence shows

Historians and media scholars who have reexamined the episode have found that the evidence for mass panic is thin.

First, the audience was small. The broadcast aired opposite one of the most popular programs on radio, NBC's Chase and Sanborn Hour with ventriloquist Edgar Bergen. A ratings survey conducted that night by the C. E. Hooper company reportedly found that only about 2 percent of those surveyed were listening to the Welles program, and those respondents said they were listening to a play, not the news.

Second, Cantril's figures rested on a much later survey and on extrapolation. His estimate of how many people heard the broadcast came from a Gallup-style poll taken weeks after the event, by which point the newspaper coverage had shaped what people remembered and what they thought they were supposed to have felt. Being "frightened" or "disturbed" is also very different from panicking. Many people who were briefly alarmed simply changed the station, checked with neighbors or called someone.

Third, the newspaper stories themselves were largely anecdotal. Specific claims of deaths, suicides and mass flight were never substantiated. The few concrete incidents that were reported were scattered and small, and some stories were repeated from paper to paper without independent checking.

Fourth, newspapers had a motive. In the late 1930s radio was taking advertising revenue from print, and it had become a rival source of breaking news. A story showing that radio was irresponsible and dangerous suited the commercial interests of the press. Media historians Jefferson Pooley and Michael J. Socolow argued in a widely read 2013 essay that the press seized on the broadcast to discredit its competitor.

A. Brad Schwartz's 2015 book Broadcast Hysteria examined nearly 2,000 letters that listeners sent to Welles and to the Federal Communications Commission after the broadcast. The letters show that some listeners were genuinely scared, and a minority were angry at being fooled. But most letters praised the program, and the collection as a whole does not support a picture of mass hysteria.

Some people were frightened, the police and newspapers did receive calls, and the FCC investigated. The broadcast led to no punishment for CBS, but networks became more careful about simulated news bulletins.

Why it persists

The story persists because it is vivid and flattering to almost everyone who tells it. It flatters the media, by suggesting broadcasting has enormous power. It flatters audiences today, who can feel superior to supposedly gullible listeners in 1938. And it offers a ready-made lesson whenever a new technology arrives: television, the internet, social media and artificial intelligence have each been described as capable of causing a modern "War of the Worlds" moment.

Welles himself benefited from the story. The notoriety helped launch his film career, and he gave interviews for decades that kept the legend alive.

The irony is that the story is itself an example of what it claims to warn against: a sensational media account, amplified by repetition and given a gloss of scientific authority, that became accepted fact.

Lessons for readers

Treat dramatic accounts of mass behavior with caution. Panics, riots and stampedes are often reported from a few anecdotes and generalized to whole populations.
Ask who benefits from a story. In 1938 newspapers had a commercial interest in portraying radio as dangerous.
Distinguish between "some people" and "millions of people." A small number of real incidents does not prove a widespread phenomenon.
Check how a statistic was produced. Cantril's 1.2 million figure came from a later survey and extrapolation, not from direct measurement.
Be skeptical of stories about other people's gullibility, especially when they make the teller feel clever.
