There are many other examples of beliefs like the Soviet one in abiogenic oil: Germans and low blood pressure, Japanese and blood types, Koreans and fan death, 19th-century Americans and the belief that masturbation causes insanity, Anglophones (or at least Americans and Brits) and the belief that eating carrots improves eyesight.
You do realize these beliefs have very different status. For example, I get the impression that modern Japan scientists don't believe in the connection between blood type and personality, and I haven't seen evidence that fan death was ever more than an urban legend that was never taken seriously by Korean scientists. Whereas abiogenic oil was a well-respected scientific theory.
The carrots and eyesight thing apparently started out as a WWII disinformation campaign to explain why a lot more German bombers were being shot down (really due to radar), in this respect it's more comparable to the Soviet red mercury hoax.
The Korean Wikipedia article starts by calling it a superstition, but then quotes Korean physicians on both sides.
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.
