There was a time when a lie at least had the decency to blush. Now it books a studio slot and accuses its critics of censorship.
“Post-truth” is the tidy label for a grubby condition in which objective facts carry less weight than emotion, identity and grievance. Truth still exists. It has simply been demoted. Whether something is accurate matters less than whether it feels right. Evidence becomes optional. Loyalty does not.
This is not a complaint about losing arguments. Nor is it confined to one ideology. Whenever identity outruns evidence, the same erosion begins. The problem is structural, not partisan.
Trust in institutions took repeated knocks - Iraq, the financial crisis, expenses, bailouts. Some scepticism was earned. Institutions are imperfect and should be scrutinised. But scrutiny is not the same as dismissal. Demanding evidence is how institutions are corrected. Declaring them corrupt whenever they deliver unwelcome conclusions is how they are hollowed out.
Economic stagnation widened the crack. When wages stall and official graphs show recovery, people assume the graphs are fraudulent rather than incomplete. That gap between lived experience and aggregated data became fertile ground for louder, simpler explanations.
Then social media industrialised human bias. Platforms optimise for engagement, not accuracy. Anger travels faster than nuance. Repetition inside algorithmic echo chambers begins to feel like proof. Corrections arrive late and limp. This is not conspiracy. It is incentive design.
The UK press operates within a concentrated ownership structure - a handful of proprietors control most national circulation - and commercial pressure rewards provocation. Serious journalism survives, but outrage is efficient. The incentives align again.
In that environment, politics shifts. Bold assertion outperforms careful qualification. Institutional pushback becomes sabotage. Judges are activist. Regulators are partisan. Markets are hysterical. The referee becomes the enemy.
Boris Johnson should have been a warning. The £350 million Brexit claim was widely challenged and widely effective. Constitutional limits were tested. Criticism was reframed as obstruction. His fall showed that arithmetic and law still matter. Yet for some, the lesson absorbed was not caution but method. Narrative stamina can win.
This dynamic is not uniquely British. Donald Trump demonstrated at scale how repetition, dismissal of unfavourable facts as “fake”, and framing legal scrutiny as persecution can sustain loyalty even when claims collide with verified outcomes. Once narrative and identity fuse, correction feels like attack.
Science feels the strain. Proper science is cautious and self-correcting. That nuance is weaponised as weakness. The existence of uncertainty becomes proof of conspiracy. A meme with a chart outruns peer review. Courts feel it too. They are not flawless, but they operate through evidence and procedure. Undermining that framework because an outcome is unwelcome is different from reforming it.
Where does this lead?
At first, to dysfunction. Policies unravel on contact with arithmetic. When fiscal claims ignore basic sums, borrowing costs rise. When court rulings are framed as partisan, compliance weakens. These are measurable consequences, not rhetorical ones.
Further on, to institutional fatigue. Expertise becomes suspect. Elections are framed as existential contests in which defeat must mean fraud. The system still operates, but less reliably and at greater cost.
Who benefits? In the short term, political opportunists untroubled by contradiction. Media actors who monetise outrage. Wealthy interests who prefer distraction to scrutiny. Foreign adversaries who thrive on division.
Who does not? Citizens who rely on functioning services, predictable rules and enforceable law. In other words, most people.
Post-truth is not destiny. It is an incentive structure. It persists only if rewarded. Voters can demand proof. Media can privilege verification over provocation. Institutions can defend evidential standards without claiming infallibility.
Truth is not glamorous. It is inconvenient and often dull. But it is structural. Remove it, and everything still looks impressive for a while.
Until it doesn’t.
