I don’t know anything about uranium separation, but is it possible the situation was not “Arthur Compton has the best idea, nobody needed to repeat it because they all remembered it on one hearing” and was more like “Arthur Compton started the meeting by setting out the main Uranium separation plan we all know well and have been leaning towards for weeks, and everyone lay out their previously hotly argued views and no dealbreakers with better alternatives arose so the committee agreed on the way”. Or perhaps that nobody had any stake in doing Uranium separation one way over another way for personal identity reasons? Perhaps the surprising bit was that they could all agree on the not-ideal method because they needed to move on and the meeting was a formality of agreement and alignment, not a brainstorming fight for your own idea session? We have another anecdote of Feynman being shown blueprints of a nuclear power plant and he doesn’t understand and eventually asks a stupid question about a part, “expecting” to be laughed at and told it’s a door, but it turns out to be a valve which could cause a problem if it fails. Nobody else had noticed, implying they were pretending their understanding, and they left thinking he was a great insightful man which he’s saying he isn’t (but is likely downplaying for comedy as well as humbleness)
