Introduction
A myth often survives not because it has strong evidence, but because it sits inside a mental model that explains away the lack of evidence. Conspiracy-based explanations are a particularly powerful example. In many conspiracy models, official denials, failed predictions, missing proof, expert disagreement, and even direct refutations are not treated as problems. Instead, they are reinterpreted as signs that the conspiracy is working. Researchers describe this pattern as a form of “self-sealing” or “self-insulating” reasoning: contrary evidence is absorbed into the theory rather than forcing it to change.

It is that the wider model already contains an explanation for why disconfirming evidence should be expected.
Why disconfirming evidence can be absorbed
Most ordinary explanations make risky predictions. If the prediction fails, confidence in the explanation usually declines. Conspiracy models often operate differently. They can be modified so that almost any outcome appears consistent with the underlying claim. Researchers studying conspiratorial thinking have repeatedly noted this tendency for counter-evidence to be reinterpreted as support. [University of Bristol]research-information.bris.ac.ukUniversity of Bristol Lewandowsky, S., & Cook, J2020).

- Missing evidence becomes evidence of concealment. If proof cannot be found, the absence itself is explained as the result of suppression or destruction.
- Contradictory evidence becomes planted evidence. Documents, testimony, or data that challenge the claim are portrayed as deliberate disinformation.
- Failed predictions become proof of intervention. If an expected event does not occur, believers may argue that conspirators changed their plans after being exposed.
- Expert consensus becomes evidence of coordination. Agreement among specialists is interpreted not as independent confirmation but as a sign that institutions are working together.
The result is a system in which the theory gains explanatory flexibility. Each contradiction can be converted into another piece of the story rather than a reason to abandon it. Lewandowsky and Cook describe this as a hallmark of conspiratorial thinking: evidence against the theory can be treated as evidence for it. [University of Bristol]research-information.bris.ac.ukUniversity of Bristol Lewandowsky, S., & Cook, J2020).

This does not mean every allegation of conspiracy is automatically irrational. Real conspiracies do occur. The distinctive feature is not suspicion itself but the tendency to make the claim increasingly resistant to revision by redefining any challenge as part of the plot.

How contradictions become signs of confirmation
The key mechanism is a shift in the meaning of evidence. Instead of asking, “What would count against this idea?”, the model begins with the assumption that hidden actors are manipulating appearances.
Consider the logic:
- Powerful actors are assumed to be concealing the truth.
- Therefore public information is potentially deceptive.
- Any evidence contradicting the theory comes from public information.
- Therefore contradictory evidence may itself be proof of concealment.
Once this pattern is established, contradictions stop functioning as tests. They become expected features of the world. The theory is no longer evaluated against evidence alone; it is evaluated through a prior assumption that evidence has been corrupted.

Similarly, a conspiracy model becomes difficult to falsify when every possible outcome is already incorporated into the narrative.
Institutional distrust as a protective frame
Conspiracy models rarely rely on a single factual claim. More often, they depend on a broader framework of distrust.
In this framework, institutions such as governments, universities, scientific organisations, news media, courts, or public health agencies are viewed as fundamentally unreliable. Once that assumption is accepted, evidence from those institutions can be dismissed before it is examined.
Research suggests that conspiratorial worldviews are associated with generalised suspicion about how knowledge is produced and communicated. A conspiratorial mindset often treats official sources as politically or strategically motivated, making institutional disagreement appear unsurprising rather than disconfirming.

- Experts who disagree are assumed to be compromised.
- Journalists who investigate are assumed to be participating in the cover-up.
- Researchers who publish contrary findings are assumed to be pressured or manipulated.
- Ordinary people who reject the theory are assumed to have been deceived.
The theory therefore does more than explain an event. It also explains why other people do not accept the explanation. This is one reason conspiracy narratives can remain stable despite widespread disagreement. The disagreement itself is incorporated into the model.

Why correction alone can strengthen commitment
A common misconception is that stronger rebuttals automatically reduce belief. In reality, direct contradiction can sometimes be interpreted through the same conspiratorial lens.
If someone already believes that authorities conceal the truth, a forceful official correction may be read as exactly what conspirators would say. The correction is not processed as neutral evidence. It is processed as another event requiring explanation, and the existing model already supplies one.

Popular discussions often refer to a broad “backfire effect,” but contemporary research finds that strong belief-reinforcing backfire effects are less common and less robust than early accounts suggested. Nevertheless, corrections can fail when they do not address the underlying explanatory model that makes the myth coherent.

The important point is not that facts never matter. Rather, facts compete with an interpretive framework that may already define which facts are trustworthy.
How corrections avoid feeding the model
Because the mechanism is model-based, effective correction involves more than presenting a contradiction.
Research and practical guidance on misinformation suggest several approaches that are less likely to strengthen self-sealing reasoning:
- Explain the reasoning error, not just the factual error. Showing how a claim turns every outcome into confirmation helps people recognise the pattern.
- Provide an alternative explanation. Replacing a myth with a more complete account reduces the explanatory gap that the myth was filling.
- Distinguish justified scepticism from universal distrust. Acknowledging real institutional failures can prevent corrections from sounding like demands for blind trust.
- Encourage testability. Asking what evidence would genuinely change the conclusion highlights whether the claim is functioning as a hypothesis or as an unfalsifiable belief.
- Focus on evaluation standards. The question becomes not whether institutions are perfect, but whether the same standards of evidence are applied consistently to all explanations.
