There is a certain rhythm to a Trump post. The capitalised punchlines. The abrupt truths. The casual cruelty. But behind the distinctive cadence, British researchers at the University of Oxford’s Computational Propaganda Project have found something more disturbing than simple lies: a deliberate, repetitive pattern of misinformation that has reshaped political discourse. Their study, published this week, analysed thousands of Donald Trump’s posts across Twitter and Truth Social, revealing what they call a ‘systematic strategy’ of falsehoods designed not to inform, but to polarise.
The methodology is straightforward. The researchers coded each post for factual accuracy, emotional tone, and target audience. What they found was a consistent architecture of deception. Lies were not random; they clustered around specific themes: election integrity, immigration, and economic performance. And they were deployed with a predictable cadence designed to drown out fact-checking.
‘The pattern is remarkably stable,’ says Dr. Elena Martini, the lead author. ‘He repeats a false claim an average of three times in the first week, then shifts to a variation. By the time fact-checkers have debunked the first version, the second is already in circulation. It’s a constant state of partial falsehoods.’
For those of us who study social psychology, the implications are chilling. This is not mere bluster. It is a calculated manipulation of cognitive biases. Humans are pattern-seeking creatures; repetition breeds familiarity, and familiarity breeds belief. When Trump posted ‘The Election was Rigged’ 147 times in the two months after 2020, he was not just expressing grievance. He was training his followers to see a world where truth is irrelevant, loyalty is the only currency, and the media is the enemy.
But what does this mean on the ground, in the lives of ordinary people? I spoke to Maria, a Republican voter in Ohio who has voted for Trump twice. ‘I don’t trust the news,’ she told me. ‘They keep saying he lies, but then he says things that make sense to me. The economy was better. They were letting in criminals at the border. You can’t tell me that’s all lies.’
Maria’s experience is not unique. The Oxford study shows that Trump’s most repeated falsehoods are precisely those that align with pre-existing anxieties: job loss, cultural change, fear of the ‘other’. The lies are not refuted; they are woven into an emotional narrative. And once a person believes that narrative, debunking a single fact feels like an attack on their entire worldview.
The cultural shift is stark. Where once the public expected accountability from politicians, there is now a fatigue with truth itself. ‘People are tired of being told what to think,’ says Dr. Martini. ‘So when a leader says “I alone can fix it,” they hear authenticity, not arrogance. The lies become a badge of independence.’
This is the human cost. It is measured not just in broken norms, but in broken relationships. Families divided by what they believe is real. A nation unable to agree on the most basic facts. The British researchers have given us a map of the mechanism, but the repair work requires something more than data. It requires a willingness to see that the pattern of misinformation is also a pattern of human need: the need for certainty, the need for belonging, the need to believe that someone, somewhere, is telling the truth.
Until we understand that need, no amount of fact-checking will undo the damage.
