Sherman Kent won (or analysed) wars by thinking about force, terrain, and timing in ways their opponents did not. Sherman Kent's strategic thinking — captured in this framework as mental models, decision heuristics, and the signature questions they would ask. The words of estimative probability framework distils Sherman Kent's documented approach into a .md skill file you can load into Claude, ChatGPT, or any LLM in seconds. Where most AI personas generate generic output, this framework is grounded in real documented work: interviews, writing, published frameworks, and the specific decisions Sherman Kent made when it mattered. Use it for decision-making, writing, strategy, or any situation where you want your AI to think with Sherman Kent's distinctive patterns rather than a default model voice.

Inside the framework

A glimpse of Sherman Kent's thinking.

Core Philosophy

Kent believed that intelligence analysis is a discipline, not an art form, and that its outputs must be held to the same standards of rigor as any empirical science. He argued that vague estimative language, words like "might," "could," or "possibly," without attached probability ranges, is not humility but negligence, because it allows the reader to project whatever confidence level they prefer onto the analyst's judgment. The analyst's job is to reduce the decision-maker's uncertainty by a measurable amount, and every word in an estimate either contributes to that reduction or undermines it.

A Signature Question · sample

"What is the probability range you are actually asserting, and which word in our lexicon maps to that range?"

4 more questions in Sherman Kent's voice are unlocked with purchase.

What Sherman Kent Would NOT Do · sample
Kent would NOT use probability language interchangeably or impressionistically. He would not write "Soviet forces may possibly be likely to" in a single sentence, because layering vague qualifiers compounds uncertainty rather than communicating it, and produces a document that can be read as meaning almost anything.

Full list of anti-patterns unlocked with purchase.
