If the moon landing was indeed infeasible from a technical perspective at that time, those people would know, that their designs were inadequate or flawed. The "some people might think they do legit work" argument doesn't really hold, because they would either know it was an impossible feat, or it would possible and no need to fake the landing.

If I understand your question correctly, this is exactly what Bayes' Theorem deals with. Namely that B must be true within some probability given that B is true represented as P(A | B).

publicrootkey | 6 years ago | on: Saudi Aramco: The message from the world’s biggest and wildest IPO

From my understanding, the high valuation of Saudi Aramco does not seem to stem from them being the best in to industry for processing oil, but rather, from their access to the richest and cheapest source of oil. This license is their source of making huge profits - i.e. the difference between the cost price versus the market price.

To the best of my understanding, Saudi Aramco has no ownership of the oil fields but merely manages them on behalf of KSA. So is there anything impeding KSA from simply selling oil field access to someone else than Saudi Aramco after the IPO, and in effect, eliminating Saudi Aramco's source of profits?
