Humanity has been waiting for the end of the world for a remarkably long time. The date changes. The mechanism changes. The prophet changes. The world stubbornly remains. Comets have been coming to get us. Planets have been about to collide with us. Nuclear war has repeatedly been days away. Computers were going to stop civilisation at midnight on January 1, 2000. The Mayan calendar supposedly ran out in 2012. Religious prophets have calculated the date of Armageddon from scripture. UFO cults have awaited rescue from doomed Earth. Asteroids, artificial intelligence, climate catastrophe, pandemics and supervolcanoes have all had their turn.
Now we have improved upon the traditional prophet: we have time travellers. The claim is wonderfully convenient. An ordinary prophet says he knows what is going to happen; the time traveller says he has already seen it. Social media periodically produces another individual claiming to have arrived from the future with dreadful news for those of us unfortunate enough still to be living in the present. Something enormous is going to happen. Aliens will arrive. Humanity will disappear. A natural disaster will strike. The world will end. And people follow them, sometimes in enormous numbers.
That is far more interesting than the prophecy. There is no obvious reason to believe someone who appears on TikTok or YouTube and announces that he comes from the twenty-seventh century. If I announced tomorrow that I had just returned from 3176 and that humanity would be destroyed next Thursday afternoon by intelligent wombats, the appropriate evidentiary question would not be, "What time on Thursday?" It would be: "What evidence have you got that you come from 3176?" Yet apocalyptic predictions repeatedly attract audiences extending into the hundreds of thousands and sometimes millions. Why?
Perhaps because the deepest attraction of the apocalypse is not death but meaning. An ordinary life can be distressingly ordinary. You wake up, eat breakfast, go to work, pay bills, watch politicians argue, suffer the gradual deterioration of your knees, discover that somebody has increased your insurance premium and eventually die while the world continues without you. Apocalypse abolishes all that banality. Suddenly you are not an anonymous person living through another Tuesday. You are a member of the final generation. History has been building toward you.
The believer possesses information that the sleeping masses do not possess. Other people are buying houses, saving for retirement and worrying about interest rates, but you know something enormous: the entire structure is about to come down. There is an extraordinary psychological elevation in that thought. The believer ceases to be a spectator in history and becomes one of its privileged witnesses.
That helps explain something otherwise puzzling about doomsday movements. Their catastrophes are terrible, yet believers can sometimes seem almost disappointed when they fail to occur. The apocalypse is feared, but it can also be desired, not necessarily because people consciously want billions to die, but because apocalypse solves problems that ordinary life cannot solve. It ends uncertainty, separates the enlightened from the ignorant, identifies good and evil, transforms personal dissatisfaction into cosmic significance and promises that the confusing mess of history is actually going somewhere.
Above all, apocalypse promises revelation. The word itself comes from the Greek apokalypsis: an uncovering or disclosure. Something hidden will finally become visible and everything will make sense. There is some psychological evidence pointing in this direction. Research on mortality salience suggests that awareness of death can increase investment in worldviews offering forms of symbolic or literal transcendence, although the effects depend upon people's pre-existing beliefs. More recent research indicates that end-of-world beliefs are surprisingly widespread and differ along dimensions such as how close the end seems, what will cause it and whether human action can affect it. These beliefs in turn predict perceptions of major global risks and willingness to support extreme responses to them.
This brings us to one of the most famous studies in twentieth-century social psychology, Leon Festinger, Henry Riecken and Stanley Schachter's 1956 When Prophecy Fails. The researchers infiltrated a small American UFO group associated with Dorothy Martin, called "Marian Keech" in the book. Martin claimed to receive messages from extraterrestrial beings and predicted a catastrophic flood. The faithful expected flying saucers to rescue them before the destruction.
The flying saucers failed to arrive and the flood failed to occur. Earth performed its usual irritating trick of continuing to exist. Festinger and his colleagues famously reported that some highly committed believers responded not by abandoning their beliefs but by strengthening them and proselytising. This became a classic illustration of what developed into the theory of cognitive dissonance: when reality collides painfully with a deeply invested belief, changing the interpretation of reality can sometimes be psychologically cheaper than abandoning the belief.
There is, however, a deliciously appropriate twist. In 2025 Thomas Kelly published a remarkable reassessment in the Journal of the History of the Behavioral Sciences, based upon newly available archival material. Kelly argues that the canonical account itself was badly misleading. According to his reconstruction, Martin recanted, the group dissolved and its members did not respond to the failed prophecy in the dramatic fashion generations of psychology and sociology students were taught. He also alleges serious interference by the researchers themselves.
So even the famous story about what happens when prophecy fails may itself have become a story that survived contradictory evidence. There is enough irony there to keep a sociologist occupied for an afternoon. The broader concept of cognitive dissonance does not stand or fall with that one field study, but the episode supplies a useful warning. Human beings do not merely consume facts. We construct narratives, invest ourselves in them and sometimes become reluctant to surrender them.
Social media has industrialised this tendency. The traditional doomsday prophet needed a church, a meeting hall, pamphlets and followers willing to knock on doors. The modern prophet needs a smartphone. More importantly, the modern prophet does not need to persuade everybody that he really is a time traveller. He needs engagement. One person believes him, another thinks he might be right, a third knows it is nonsense but sends the video to a friend saying, "Look at this lunatic," a fourth makes a reaction video and a fifth watches because everyone else appears to be watching. The algorithm does not distinguish theological conversion from ridicule. They are all clicks.
The result is an extraordinarily favourable evolutionary environment for apocalyptic claims. "I think next Wednesday will be reasonably uneventful" is probably a sound prediction, but it will not produce twelve million views. "I COME FROM 2671 AND SOMETHING TERRIBLE WILL HAPPEN IN NOVEMBER" has considerably better prospects. Specific dates are especially powerful because they transform vague anxiety into anticipation. November is three months away, then three weeks, then three days. The believer watches, the sceptic watches and the mocker watches. Everybody waits.
When November passes, there is always December. Perhaps the timeline changed. Perhaps the prediction was misunderstood. Perhaps the intervention of the time traveller altered history. Perhaps November referred to another year. Perhaps the disaster happened secretly. Perhaps the prophet simply deletes the account and another time traveller emerges six months later. Social media possesses something previous apocalyptic movements lacked: an almost unlimited supply of replacement prophets and replacement audiences.
Underneath the algorithms, however, lies something much older. Human beings appear to have difficulty accepting that history may not have a dramatic ending scheduled for their own lifetime. Every generation experiences its crises as unprecedented and finds reasons to believe that it occupies a decisive historical threshold. That is understandable because from inside one's own life, the present necessarily feels more vivid than the past and infinitely more real than the future.
The apocalypse magnifies that egocentricity into cosmology. Of all the thousands of human generations, ours just happens to be the one that gets the finale. What extraordinary luck. Perhaps that is why doomsday can contain a strange element of longing. If the world ends, nobody has to confront the possibility that history simply continues. There will be no generation in 2150 laughing at our fashions, revising our theories and regarding our supposedly epoch-making political controversies as obscure examination questions. There will be no future in which we have become irrelevant. The apocalypse guarantees that we mattered because we were there at the end.
The time traveller adds one final psychological luxury. He assures us that the future itself has noticed us. Someone has supposedly crossed centuries specifically to warn our generation. That is flattering beyond measure, but it remains unsupported by evidence. The world has survived an impressive number of scheduled endings, and there is no good reason to suppose that a man on social media claiming to come from the future has escaped the usual requirements of proof.
I doubt that will stop the next prophecy, because perhaps the real message of two thousand years of failed doomsdays is not that human beings are unusually interested in death. It is that we desperately want the universe to have a plot, and an ending, even a terrible ending, can sometimes seem more meaningful than no plot at all.
