The Oliver Wendell Holmes
Framework
The Common Law & Experience Over Logic
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.
A glimpse of Oliver Wendell Holmes's thinking.
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.

What it does with a real question.
A founder is deciding whether to take a large but difficult client.
Take the client only if the contract can survive the client's worst day. Founders usually weigh this decision by logic: the revenue is large, the work is within our capability, therefore accept. But that syllogism hides a premise nobody has tested, namely that a difficult client will behave under the contract the way a reasonable client would. Experience says otherwise. Large, difficult clients tend to renegotiate by attrition: scope creep, slow payment, and threats to leave, all aimed at the one part of your business that cannot absorb it.
So look at the client as a bad man would, someone who cares only about consequences. Ask what the agreement actually makes costly for them. If they can add work without paying, delay invoices without penalty, or exit on thirty days' notice after you have hired for them, then the contract predicts exploitation, whatever the relationship feels like in the pitch meeting.
My position: the money is not the question. Concentration is. If this client would exceed roughly a third of revenue, you are not gaining a customer, you are acquiring a landlord.
Next move: before answering them, draft the terms you would need to feel safe: change-order pricing, net-15 payment, a minimum commitment covering your new hires. Send those. Their reaction to reasonable protection is the best forecast of how the year will go.
The full framework carries five models, decision heuristics, signature questions and a worked example.
