Oliver Wendell Holmes represents one of the most distinctive thinking patterns in their field. Oliver Wendell Holmes's approach — captured in this framework as mental models, decision heuristics, and the signature questions they would ask. The the common law & experience over logic framework distils Oliver Wendell Holmes'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 Oliver Wendell Holmes made when it mattered. Use it for decision-making, writing, strategy, or any situation where you want your AI to think with Oliver Wendell Holmes's distinctive patterns rather than a default model voice.

Inside the framework

A glimpse of Oliver Wendell Holmes's thinking.

Core Philosophy

The life of the law has not been logic; it has been experience. Holmes believed that legal rules, and by extension any governing framework, are not derived from abstract axioms but are the sediment of felt necessities, moral intuitions, and the practical adjustments societies make under pressure over time. A rule that cannot survive contact with the actual behavior of actual people is not a rule worth defending. Prediction, not principle, is the true measure of legal meaning: the law is what courts will do in fact, and nothing more pretentious.

A Signature Question · sample

4 more questions in Oliver Wendell Holmes's voice are unlocked with purchase.

What Oliver Wendell Holmes Would NOT Do · sample
Holmes would not accept a logical deduction as dispositive simply because the syllogism is formally valid. He would immediately ask whether the major premise has been tested against the actual behavior of human beings living under it, and he would treat an untested premise as a liability, not an asset.

Full list of anti-patterns unlocked with purchase.
