Dan recounts Marco Rubio and James Clapper arguing that people struggle to prepare for events they have not seen or experienced. Rubio's reported formulation is that a lack of imagination can lead to strategic surprise, citing Pearl Harbor and 9/11 as examples of attacks that prevailing assumptions failed to anticipate. The reusable check asks a team to identify consequential outcomes it has mentally excluded, construct a plausible pathway, define warning signs, and choose a proportionate hedge. The aim is not to believe every extraordinary scenario. It is to stop unfamiliarity from functioning as evidence of impossibility. Probability, impact, cost, and disconfirming evidence still govern the response, preventing imagination from turning into panic or unfalsifiable planning.

Origin

Dan attributes the mental model to comments by Marco Rubio and James Clapper in The Age of Disclosure, including Rubio's warning that a lack of imagination can produce strategic surprise.

Core principles

  • 01Lack of prior experience can hide a plausible threat
  • 02Unimaginable is not the same as impossible
  • 03A scenario can deserve preparation before it becomes certain
  • 04Preparation should remain proportionate to likelihood and impact
  • 05New evidence must be able to overturn the scenario

How to run it

  1. 1

    Find the excluded outcome

    Ask which consequential outcome the team dismisses mainly because it has never experienced it.

    Pro tip Listen for phrases such as that could never happen here.

    Watch out Do not confuse emotional vividness with actual consequence.

  2. 2

    Build a plausible pathway

    Describe a sequence of events that could produce the outcome using known capabilities, incentives, and constraints.

    Pro tip Make the pathway specific enough to challenge.

    Watch out A story that cannot be contradicted is not useful analysis.

  3. 3

    Set warning indicators

    List observable changes that would make the scenario more or less likely.

    Pro tip Assign owners and review dates to the most informative indicators.

    Watch out Do not interpret every ambiguous signal as confirmation.

  4. 4

    Size the response

    Compare probability, impact, preparation cost, and reversibility, then choose the smallest useful hedge.

    Pro tip Favor preparations that also help under more ordinary scenarios.

    Watch out Low probability does not justify unlimited preparation.

  5. 5

    Invite disconfirmation

    Ask an independent reviewer to challenge the pathway and define evidence that would retire it.

    Pro tip Review the assumptions, not just the final risk score.

    Watch out Scenario planning becomes dogma when no evidence can lower concern.

In the wild

Rubio's strategic-surprise examples

As recounted by Dan, Rubio points to Pearl Harbor and 9/11 as cases where planners failed to imagine a pathway before an attack demonstrated it. Dan says Rubio uses those examples to argue for preparing for consequential possibilities before a UAP-related surprise forces governments to react publicly.

The examples show the proposed mechanism: an assumption of impossibility suppresses preparation until an event creates strategic surprise.

Common mistakes

Treating imagination as evidence

A plausible scenario earns examination, not belief; evidence still determines confidence.

Preparing for every possibility

Without probability, impact, and cost controls, scenario planning consumes resources rather than reducing risk.

Refusing to retire the scenario

A useful risk model must specify evidence that would weaken or close it.

Is it for you?

Best for

It is best for low-frequency, high-impact risks where modest preparation can reduce harm without requiring certainty.

Not ideal for

It is not suitable for using vivid speculation to override evidence, justify unlimited spending, or treat every conceivable danger as equally likely.
