Living in Different Worlds

The Red Line: Shared Reality

Human societies depend on something fragile and easily overlooked: a contestable, shared sense of what is real.

Not uniform opinion.
Not ideological agreement.

But a common arena in which:

• events can be jointly acknowledged,

• evidence can circulate,

• claims can be challenged publicly,

• and disagreement can occur on shared ground.

Democracy does not require consensus.
It requires a floor strong enough to bear disagreement.

When that floor weakens, debate does not simply become heated.
It becomes impossible.

You cannot act together if you cannot agree on what is happening.

What Is the Splinternet?

For most of its short history, the internet functioned, at least in aspiration as a largely shared global network. A website accessible in London was generally accessible in Delhi, Johannesburg, or São Paulo. Information could move across borders with relatively little friction.

The term splinternet describes the fragmentation of that shared network into separate, partially sealed ecosystems.

This fragmentation can take several forms:

• Governments blocking or throttling specific platforms.

• National firewalls restricting cross-border information flow.

• Domestically approved alternatives replacing global services.

• Infrastructure that enables selective shutdowns during unrest or elections.

The result is rarely a total blackout.

More often it is something subtler:

Citizens remain online but within a curated subset of the global web.

The internet becomes nationalised.

Infrastructure is neutral in theory.
It is political in practice.

A data centre can represent resilience.
It can also become a switch.

A sovereign AI initiative can reduce dependence on foreign monopolies.
It can also centralise narrative control.

The splinternet is not merely geopolitical.
It is epistemic.

Fragmentation From Within

At the same time, another force is reshaping shared reality from the inside.

AI systems and algorithmic platforms now:

• filter what we see,

• rank what we read,

• summarise complex events,

• personalise informational streams at scale.

They do not remove information outright.
They sort it.

This produces a quiet but profound shift.

Two citizens in the same street can encounter:

• different accounts of the same protest,

• different framings of crime or immigration,

• different economic interpretations,

• different “experts” speaking with authority.

Reality does not disappear.

It multiplies.

This is not censorship.
It is hyper-personalisation.

AI fragments reality from within via personalised streams.

Fragmentation From Above

The splinternet represents a different mechanism.

Here, fragmentation occurs through control of access:

• information is narrowed,

• cross-border narratives are restricted,

• certain sources become unreachable,

• contestation becomes infrastructurally difficult.

This produces not too many incompatible truths but too few authorised ones.

Shutdowns and splinternet architectures fragment reality from above.

Loss of Shared Reality vs Curated Reality

We are therefore facing two distinct conditions:

Loss of Shared Reality

Fragmentation through abundance.
Too many incompatible streams.
Too much narrative divergence.

Curated Reality

Fragmentation through enclosure.
Restricted access.
Narratives filtered at the border.

One feels chaotic.
The other feels controlled.

Different mechanism. Same cliff.

In both cases, what erodes is the same:

The loss of a contestable, shared ground of fact.

When Epistemic Fracture Becomes Moral Fracture

At first, this seems technical, about algorithms or infrastructure.

But its consequences are moral.

When people no longer share a baseline account of events:

• correction feels like propaganda,

• disagreement feels like delusion,

• institutions appear partisan by default,

• opponents feel malicious rather than mistaken.

Epistemic fracture turns into moral fracture.

If I believe you are wrong, I argue.

If I believe you inhabit a fabricated reality, I withdraw or escalate.

Polarisation ceases to be about policy.
It becomes about ontology.

Voters are not simply divided.

They are living in different worlds.

The Sovereignty Tension

This is where the dilemma sharpens.

Many democracies seek to untether themselves from US tech monopolies. That impulse is understandable. Corporate concentration of informational power is itself destabilising.

But the corrective carries a danger.

How do we decentralise corporate power without centralising state control?

If the answer to platform dominance is sovereign containment, shared reality narrows.

If the answer to state control is unregulated algorithmic personalisation, shared reality dissolves.

One path concentrates power in governments.
The other concentrates it in platforms.

Both weaken epistemic cohesion.

The Real Cliff Edge

The danger is not disagreement.

It is the disappearance of a place where disagreement can occur meaningfully.

Shared reality does not maintain itself. It requires:

• infrastructure that permits contestation,

• norms that privilege evidence,

• institutions capable of scrutiny,

• citizens equipped with literacy.

When fragmentation becomes embedded in infrastructure, whether through national firewalls or algorithmic silos, recovery becomes exponentially harder.

The splinternet is not just about cables and sovereignty.

It is about whether we still inhabit a common world.

Different mechanism. Same cliff.

And once the shared ground collapses, democratic deliberation becomes theatre. Not because citizens disagree, but because they are no longer standing on the same floor.

A Case Study: Brexit

The 2016 Brexit referendum demonstrated both fragmentation mechanisms in real time.

Leave and Remain voters were not simply divided on policy. They were inhabiting incompatible informational realities about what the EU was, what Brexit would mean and what evidence counted as credible.

Fragmentation from within:
Algorithmic feeds delivered different streams to different voters. Immigration statistics circulated heavily in one informational ecosystem. Economic forecasts and trade analysis dominated another. The £350 million NHS bus claim travelled powerfully in one stream while being debunked in another. Micro-targeted messaging meant voters in the same household could receive different framings tailored to psychological profiles.

Both sides believed they were responding to reality itself.

Fragmentation from above (institutional collapse):
Simultaneously, shared institutional authority weakened. Treasury forecasts were dismissed as “Project Fear.” The BBC was accused of bias by both sides. Expert testimony was reframed as elite manipulation. When Michael Gove said that people had “had enough of experts,” he was not merely making a rhetorical point, he was accelerating the erosion of a shared epistemic infrastructure.

The result was not just disagreement about EU membership.

It was two populations living in parallel epistemic universes, each convinced the other had been misled.

Years later, voters still struggle to agree on what Brexit was meant to achieve, whether it succeeded, or what evidence would settle the question. Not because data is unavailable, but because there is no longer a shared frame for assessing it.

Epistemic fracture became moral fracture in real time.

“If you disagree with me, you are not just wrong, you are deceived.”
