When US and UK civilian physicists voluntarily ceased publishing their earth-shattering discoveries in 1939-40 to arrest Germany's push for the Bomb, they inadvertently tipped off Soviet scientists to the existence of a large, secret program to harness the power of the atom.
David Holloway's Stalin and the Bomb covers this well: https://books.google.com/books?id=ICO6aUnQ2KcC&lpg=PP1&pg=PA78#v=onepage&q&f=false …pic.twitter.com/HCb4YKgoZQ
US science journalists noticed the same thing as an aside:pic.twitter.com/CbG4V7lOtj
Wasn’t Szilard a big driver in the early initial self censorship movement on the atomic fission front? If so, it’s kind of ironic as he later seemed to despise it later on.
In general scientists support practices of secrecy when they feel they are in control of them, when they don't impinge on their autonomy. When they feel it is externalized (in Szilard's case, controlled by others, esp. the military), they rapidly find it inhibiting.
To put it another way, it's the difference between self-regulation (which scientists often support) and government regulation (which they don't) of potentially dangerous research.
In the case of the Manhattan Project the secrecy regimes shifted from self-censorship (Szilard) --> control by civilian scientific agencies (Bush) --> control by the military (Groves). Szilard was lukewarm about the second step and hated the third.
What about Bohr? It somewhat seemed like there were some real concerns with him keeping secrets.
