Down to the Indivisible: Fact, or Someone Else's Conclusion?
Take a question down to facts that cannot be divided further and most of the argument disappears; what remains is the real problem.
"The market price is eighty dollars a kilo" is a conclusion, not a fact. The facts sit one layer down: how many synthetic steps, what overall yield, what the raw materials cost per unit, how many machine-hours a batch consumes, how long capital is tied up. Push every piece of industry common sense one layer down and ask where it came from, until you reach items like route, yield, hours and capital that cannot be divided further.
The test for a genuine fundamental is independent verifiability — invoice-level material prices, process-level yields, scheduling-level hours. Anything you cannot specify a verification method for is another packaged conclusion. Most arguments stall because both sides are stacking conclusions and calling them facts. Rebuild afterwards: cost is the sum of fundamentals, time is the sum of the critical path, feasibility is what physics allows. If the rebuilt number diverges widely from convention, the gap is either an opportunity or a term you forgot to split.
