The War of the Worlds Panic

Summary

On Halloween eve in 1938, Orson Welles broadcast an adaptation of The War of the Worlds as a sequence of simulated news bulletins, and America is said to have panicked. It did not. The audience was tiny, the panic was close to unmeasurable, and the story of the panic was manufactured by newspapers with a commercial reason to make radio look dangerous. What actually deceived the public was not the broadcast. It was the coverage of the broadcast, and it worked for eighty years.

What is documented

The broadcast. On the evening of 30 October 1938, the Mercury Theatre on the Air, on CBS, presented Welles's adaptation of H. G. Wells's 1898 novel. It was structured as interrupted programming: a dance band, broken into by news flashes reporting landings in New Jersey. The programme was scheduled. It had been running for months. It was announced as a play at the start, and identified as one again partway through.

Almost nobody was listening. The C. E. Hooper ratings service was in the field that night, telephoning households and asking what they were tuned to. Of roughly five thousand households surveyed, about two per cent named the Welles programme. The overwhelming majority of the audience in that hour was listening to Edgar Bergen on NBC.

CBS checked immediately. The day after the broadcast, the network commissioned a national survey to establish how many people had heard it. Frank Stanton of CBS later recalled that the finding was a relief, because so few had tuned in, and that those who had generally treated it as a prank.

The streets were empty. Ben Gross, radio editor of the New York Daily News, walked to the studio as the programme ended. In his 1954 memoir he recorded that the streets were nearly deserted, which is not what a city in flight looks like.

The hospital story was checked, and it was false. Researchers at Princeton's Office of Radio Research attempted to verify a widely repeated rumour that people had been treated for shock at St Michael's Hospital in Newark. The rumour was investigated and found to be inaccurate.

No verified suicide. Wire services carried lurid accounts of listeners saved from self-harm by the timely arrival of a friend or neighbour. The listeners were never named. Not one newspaper reported a verified suicide connected to the broadcast.

Cantril's book, and what it actually rests on. In 1940 the Princeton psychologist Hadley Cantril published The Invasion from Mars, which put the audience at around six million, estimated that 1.7 million took it for a news bulletin, and that 1.2 million were frightened or disturbed. Those figures gave the panic its academic standing and they are the source of almost every number still quoted.

Pooley and Socolow examined the study and found its audience estimate to be more than double any other contemporary measurement. Cantril conceded the discrepancy, arguing that he had tried to capture households without telephones, whom ratings surveys missed. But those respondents were interviewed only after the newspaper coverage had saturated the country, and Cantril himself acknowledged that their recollections could have been shaped by what they had read.

Where the story came from. Radio had taken advertising revenue away from print through the Depression, and the newspaper industry was in a bad way. The broadcast handed it an opportunity: proof, for advertisers and for regulators, that radio was reckless and unfit to carry news. The papers took it. Within a day the panic was a national story, and the reporting was not investigated because investigating it was not the point.

Welles. He was apologetic in public and, in private, angry that reports of lawsuits against him were exaggerated or invented outright. In later life he stopped correcting the record and adopted the legend, which by then was the most famous thing about him.

Leading explanations

There is no anomalous event to explain. What requires explanation is the durability of the belief.

A commercial motive, and no incentive to check. The panic story served the industry that reported it. Nobody in a position to verify it had any reason to.

Academic laundering. A newspaper claim becomes a fact when a university press publishes it. Cantril's book converted sensational reporting into a citable figure, and that figure has been recycled through textbooks, documentaries and journalism ever since, each citation adding authority and none adding evidence.

It is a very good story. A nation deceived by a radio play is a parable about media, gullibility and modernity, and it has been useful to everyone who has ever wanted to make that point. Its usefulness is the reason it survived being false.

Some people were frightened. This is true and it is not the claim. A small number of listeners tuned in late, missed the framing, and were alarmed. A meaningful share of those assumed an attack by Germany rather than by Mars, which tells you what the country was actually afraid of in October 1938. Individual fright is not mass hysteria.

Current status

Debunked. This record sits in Mass and Collective for a reason that is not obvious at first: the collective delusion is real, but it is not the one in the story. Nobody was gripped by an invasion. Millions have been gripped, for eighty years, by an event that did not occur, because it was printed, then footnoted, then taught.

That is a mass psychogenic episode with a very long incubation period, and it is still running. The registry keeps it as a warning about its own method. Every case in this archive arrives through a chain of retellings, and this is what happens when nobody walks back up the chain to see what is at the top of it.
