Resist conspiracy escalation
When your explanation requires others to have coordinated secretly, apply the razor hard.
Key takeaways
- What it is: When your explanation requires others to have coordinated secretly, apply the razor hard.
- Why it works: Conspiracy explanations multiply assumptions exponentially: each additional participant requires an independent assumption that they (a) know the plan, (b) are motivated to maintain silence, and (c) have not made a mistake or defected. The probability of all assumptions holding simultaneously falls sharply with each added participant, making large coordinated conspiracies very improbable compared to simpler explanations.
- Evidence: Plausible mechanism, limited direct outcome data.
- Avoid: Treating absence of evidence against the conspiracy as evidence for it — the razor cuts the other way: absence of evidence against a simple explanation favors it.
Why it works
Conspiracy explanations multiply assumptions exponentially: each additional participant requires an independent assumption that they (a) know the plan, (b) are motivated to maintain silence, and (c) have not made a mistake or defected. The probability of all assumptions holding simultaneously falls sharply with each added participant, making large coordinated conspiracies very improbable compared to simpler explanations.
How to do it
- 1List the number of people who would need to know and stay silent for the conspiracy to hold.
- 2Ask: what is the simplest explanation that requires no secret coordination?
- 3Check whether the simpler explanation fits the observable facts equally well.
- 4Reserve the conspiracy explanation for cases where evidence directly rules the simple one out.
What the evidence says
MechanisticResearch on the mathematical sustainability of conspiracies suggests that large-scale coordinated secrets are inherently fragile — the probability of sustained secrecy drops sharply with group size and time. The Bayesian prior against them is substantial.
Honest caveat: This is a probabilistic argument, not a categorical one. Real conspiracies do occur; the razor increases skepticism proportional to assumed complexity, not to zero.

Common mistake
Treating absence of evidence against the conspiracy as evidence for it — the razor cuts the other way: absence of evidence against a simple explanation favors it.
