What’s a conspiracy theory you actually find believable?

The Paranoid’s Almanac: Conspiracy Theories That May Have More Truth Than We Think

There is something deliciously unsettling about a conspiracy theory. It whispers where history speaks in a measured voice. It joins apparently unrelated dots, suspects the footnotes, distrusts the official narrative and asks the impertinent question: What if the story we were given was merely the story we were permitted to know?

Most conspiracy theories are, of course, precisely what their name suggests—conspiracies of imagination. They thrive in the fertile soil between ignorance and suspicion, where coincidence is promoted to evidence and coincidence is dressed in the robes of causality. Yet dismissing all conspiracy theories as lunacy is itself a form of intellectual laziness.

History has an inconvenient habit of vindicating a few of them.

The important distinction, therefore, is not between people who believe conspiracy theories and people who do not. It is between claims supported by evidence and claims sustained merely by suspicion.

Some alleged conspiracies were once mocked before documents, investigations and admissions transformed them from fantasy into history.

1. MKUltra: When “Mind Control” Was Not Merely a Movie Plot

If someone had told you decades ago that the CIA had secretly investigated methods of influencing human behaviour, including the use of psychoactive substances and experiments involving human subjects, you might reasonably have thought they had been watching too many Cold War thrillers.

Yet MKUltra was real.

Declassified CIA records contain numerous documents relating to the programme and its subprojects. In June 2026, the US House Committee on Oversight and Government Reform even held a hearing titled Mind Control and Accountability: Uncovering the Truth of the CIA’s MKULTRA Project.

This does not mean every lurid claim about MKUltra is true. It means something more disturbing: the underlying premise—that intelligence agencies once pursued secret behavioural and mind-control research—was not a paranoid invention.

The lesson is profound. Sometimes reality does not merely resemble fiction.

It embarrasses fiction by being stranger.

2. COINTELPRO: The State Can Become Interested in Your Opinions

Another conspiracy theory worth taking seriously is the notion that governments have sometimes infiltrated, monitored and deliberately disrupted political organisations and movements.

Again, this is not conjecture.

The FBI itself acknowledges that COINTELPRO began in 1956 and was subsequently expanded to include organisations ranging from the Ku Klux Klan to the Socialist Workers Party and the Black Panther Party. The Bureau acknowledges that agents infiltrated groups, attempted to sow discord and sought to discredit organisations, sometimes where there was little or no evidence of unlawful activity.

That revelation should make us uncomfortable—not because it proves that every government is secretly manipulating every movement, but because it demonstrates that institutional power is capable of exceeding its declared boundaries.

The conspiracy theorist says, “The government is watching everyone.”

The historian says, “Sometimes governments have watched people they should not have watched.”

The historian wins because he has the documents.

3. Mass Surveillance: The Digital Panopticon

For years, the idea that governments could collect vast quantities of communications data sounded like the stuff of dystopian fiction.

Then came revelations concerning bulk telephone metadata.

The NSA acknowledges that its former Section 215 programme involved the compelled provision of telephone metadata—including numbers called, dates, times and durations—under court orders. The Obama administration also publicly discussed the controversy surrounding bulk telephone-record collection in 2014.

Notice the subtlety here.

The real story is not necessarily, “Someone is listening to every conversation.” That claim goes far beyond the evidence.

The more interesting truth is that metadata can reveal the architecture of a person’s life without necessarily revealing the words they speak.

Who calls whom.
When they call.
How frequently.
For how long.

A telephone record can become a shadow biography.

The modern citizen may therefore have less privacy than he imagines—not because someone is sitting in a dark room listening to every syllable, but because algorithms can infer remarkably intimate patterns from apparently innocuous fragments.

The future of surveillance may not require ears.

It may require mathematics.

4. Watergate: Sometimes the “Wild Theory” Is Simply the First Draft of History

Watergate is perhaps the ultimate reminder that conspiracy theories should not always be laughed out of the room.

A political conspiracy really did occur. There really was covert activity surrounding the 1972 break-in at the Democratic National Committee headquarters. The scandal eventually reached the highest levels of American government, and President Richard Nixon resigned.

The FBI’s own historical account records the extraordinary role of the Bureau in uncovering the Watergate affair and describes the subsequent crisis of confidence and reforms.

What began as something that could easily have been dismissed as political paranoia became a constitutional crisis.

The important lesson is not that every political scandal conceals a Watergate.

It is that power does occasionally conspire.

And when power conspires, it usually does not announce itself with thunder.

It leaves paperwork.

5. The More Believable Conspiracy: Governments Hide Things

Here is perhaps the conspiracy theory I find most believable—not a specific allegation, but a general proposition:

Governments conceal information.

That is not particularly controversial. Governments classify documents. Intelligence agencies protect sources. Military organisations conceal capabilities. Investigations are sometimes conducted behind closed doors.

The FBI, for instance, maintains the FBI Vault, an extensive repository of documents released through freedom-of-information processes.

The existence of such archives is itself a reminder that the public record is not always created simultaneously with the events it describes.

History often arrives late.

Sometimes decades late.

And that should temper our certainty whenever somebody says, “There is no evidence.”

“No evidence” can mean two entirely different things:

There is no evidence.

Or:

The evidence has not yet become available.

Those are not the same sentence.

6. The Conspiracy of Money

Here is another theory that deserves more intellectual attention: powerful economic interests sometimes influence public policy more than ordinary citizens realise.

This does not require a secret room populated by billionaires wearing identical black suits.

It requires something much more mundane—and therefore more formidable.

Lobbying.
Political donations.
Regulatory capture.
Corporate influence.
Revolving doors between government and industry.
Control over information.

The machinery of influence does not need to be clandestine to be consequential.

The real conspiracy may sometimes be perfectly legal.

That is what makes it difficult to detect.

A bribe is scandalous because it is illegal. Influence exercised through legitimate institutions can be far more subtle.

Perhaps the most sophisticated conspiracies are those that require no conspiracy at all.

7. The Theory That Algorithms Know Us Better Than We Know Ourselves

This is the conspiracy theory of our age.

People sometimes imagine that their phones are secretly listening to every conversation so that advertisements can mysteriously follow them around the internet.

The explanation may be less cinematic and more unsettling.

Algorithms do not necessarily need to hear your private conversation. They can learn from your searches, clicks, purchases, movements, viewing habits, contacts, pauses and preferences.

From thousands of seemingly trivial decisions, a remarkably intimate portrait can emerge.

The modern algorithm is a kind of digital astrologer—but unlike the astrologer, it has data.

It does not need to know your soul.

It merely needs to know your behaviour.

And behaviour, repeated often enough, becomes prediction.

What I Would Not Believe Without Evidence

There are theories that remain fascinating but unsupported: secret societies controlling every government, the Earth being flat, elaborate claims that every major historical event was staged, or the belief that a single hidden cabal orchestrates virtually everything that happens in the world.

The problem with such theories is not that they are too strange.

Reality itself is strange.

The problem is that many of these theories are constructed so that nothing can disprove them.

If evidence contradicts the theory, the contradiction itself becomes evidence of the conspiracy.

That is an intellectual cul-de-sac.

A theory that cannot possibly be falsified is not necessarily profound.

Sometimes it is simply unfalsifiable.

The Most Dangerous Conspiracy Theory

There is, however, one conspiracy theory I find particularly dangerous:

“Everything is controlled by someone.”

It is seductive because it converts chaos into architecture.

A pandemic becomes a plan.
A financial crash becomes a plot.
A war becomes somebody’s master design.
A political defeat becomes manipulation.
A personal misfortune becomes evidence of hidden forces.

But the universe is under no obligation to be coherent.

Sometimes things happen because millions of independent decisions collide.

Sometimes incompetence explains what conspiracy cannot.

Sometimes greed is decentralised.

Sometimes stupidity is sufficient.

And sometimes—perhaps most frighteningly—nobody is in control.

The Golden Rule of Suspicion

I do not think we should become believers in conspiracy theories.

I think we should become better interrogators of narratives.

Ask:

Who benefits?
What is the evidence?
What would disprove this claim?
Is there a primary source?
Are several independent sources saying the same thing?
Am I mistaking coincidence for causation?
Could incompetence explain this better than conspiracy?
Am I believing this because it is true—or because it is satisfying?

The last question may be the most important.

Human beings have an almost liturgical hunger for patterns. We dislike loose ends. We prefer villains to randomness and designs to accidents. A conspiracy gives chaos a dramaturgy.

But scepticism should cut in both directions.

We should be sceptical of the official story.

And equally sceptical of the unofficial one.

Perhaps the mature position lies somewhere between credulity and cynicism: a willingness to entertain extraordinary possibilities without surrendering our standards of evidence.

History has shown us that some conspiracies were real.

It has also shown us that countless others were not.

So I would keep the door open—but not remove the lock.

Because sometimes behind the door is a suppressed truth.

Sometimes there is merely a broom cupboard.

And occasionally, when we open it, we discover something far more unsettling than a conspiracy:

the world is complicated, power is fallible, human beings are unpredictable, and truth rarely arrives wearing a name badge.
