Yes that is an excellent point! Moral superiority and the imparitive to act are highly motivating factors. What's interesting is that when faced with the opposite senario, humans tend to default to inaction rather than be a whistleblower. Moral superiority is only motivating if the majority is on your side.
Perhaps the single most curious things in Rhode's book is what put them off the path of graphite moderated natural uranium reactors, the work of a single unreliable scientist who, as it happened, was not using pure enough graphite (too many neutron poisons, it was quite a challenge for us to get graphite pure enough). That pretty much dead ended their efforts on the science front, heavy water natural uranium reactors are quite possible (https://en.wikipedia.org/wiki/CANDU_reactor although I remember reading somewhere the Canadians had access to extra rich in U-235 uranium), but definitely not trivial, especially when we were zapping their supplies of heavy water from Norway.
