The deepfake that got through: 20% of viewers failed to spot the hoax

A video generated by artificial intelligence, barely 20 seconds long, managed to convince one in five viewers that it was real. The figure, drawn from a spontaneous reaction on social media, is no anecdote: it reflects the growing difficulty of telling the real from the synthetic in an era where AI is blurring the lines of truth.

The video, presented as a supposed piece of investigative journalism, included explicit references to online communities with very distinctive profiles. Those who watched it called it "brutal" and "brilliant", but also issued a warning: most people didn't catch on until a detail — the pronunciation of acronyms like "es-u-uve" instead of SUV — gave the game away. Even so, according to estimates, around 20% of the first viewers actually believed it was authentic.

The line between humour and disinformation

The video operated in the realm of parody, but the danger lies not in the comedic intent but in the technical quality. Generative AI can now imitate voices, faces and contexts with a fidelity that a few years ago required professional studios. The fact that a homemade video, probably the work of an amateur with accessible tools, managed to fool a significant fraction of its audience is a warning sign.

Some analyses suggested the believability lay in the mix of recognisable references with a news-broadcast format. "When the format is familiar, the brain tends to accept it without filtering," note experts in cognitive psychology. The problem gets worse when the content appeals to ideological biases or group affinity: the very people it targets become the first to share it without verifying it.

The cost of credulity in the AI era

The segarro anecdote reveals a structural phenomenon. The same technology that makes deepfakes to laugh about among friends can be used to manipulate elections, crash stock prices or discredit public figures. The 20% figure is not an official statistic — it emerged from a comment in the reaction thread itself — but it matches academic studies that put the believability rate of medium-quality deepfakes at between 15% and 30%.

Those who champion digital education as the antidote point out that critical-thinking training has been deficient for decades. "The new illiterates will be those who cannot tell the real from the manipulated," one of the comments warned. The difference is that technology is now advancing faster than education programmes.

How can you protect yourself?

The warning signs remain the same: verify the original source, look for inconsistencies in lip movement, shadows or reflections, and distrust any content that triggers an intense emotional response. But the margin of error is shrinking. The video in question only gave itself away through a tiny verbal slip; without that mistake, the 20% would have been far higher.



Given all this, the question is not whether someone will fall for a deepfake, but when you will. And what is more unsettling: would you be able to spot it?
