I am not able to access my resources at the moment, but if I recall from school, a particular politically powerful Russian scientist essentially mandated that the abiogenic petroleum theory would be the one accepted by the Russian establishment. At the time, they justified this by pointing to large oil fields for which source rocks (underlying rock containing thermally decomposed organic matter) had not been discovered. Of course since then the source rocks have been discovered.
Amusingly, if you Google "abiogenic petroleum theory" you will find lovely quack articles explaining how plausible the theory is and how it means we will never run out of oil.
Do you mean Kudryavtsev?
What kind of school was this? Russian? American? Geology? History of science?
How can you tell the difference between a "mandate" and an argument? CellBioGuy compares your story to Lysenkoism, but Lysenko called his opponents "wreckers" and had them executed. I can imagine that his example had a chilling effect on future disagreement with superiors, but if this were a systematic problem with Soviet science, why don't we have more examples?
What can we learn about science from the divide during the Cold War?
I have one example in mind: America held that coal and oil were fossil fuels, the stored energy of the sun, while the Soviets held that they were the result of geologic forces applied to primordial methane.
At least one side is thoroughly wrong. This isn't a politically charged topic like sociology, or even biology, but a physical science where people are supposed to agree on the answers. This isn't a matter of research priorities, where one side doesn't care enough to figure things out, but a topic that both sides saw to be of great importance, and where they both claimed to apply their theories. On the other hand, Lysenkoism seems to have resulted from the practical importance of crop breeding.
First of all, this example supports the claim that there really was a divide, that science was disconnected into two poorly communicating camps. It suggests that when the two sides reached the same results on other topics, they did so independently. Even if we cannot learn from this example, it suggests that we may be able to learn from other consequences of dividing the scientific community.
My understanding is that although some Russian language research papers were available in America, they were completely ignored and the scientists failed to even acknowledge that there was a community with divergent opinions. I don't know about the other direction.
