When the early American analysts compared the Soviet work to psychical research and parapsychology, they could look at the American versions and presuppose that the Soviets would get no further along than American parapsychologists had.
Even during the 1960s, parapsychology was considered a moribund field -- since after decades of working at it, parapsychology had produced nothing "threatening" much less monumental enough to achieve State support and highest scientific endorsement. And it had clearly not produced anything resembling "practical applications." And so very few of the American analysts could figure out why the Soviet effort had achieved such high support, and apparently done so as early as Kazhinski's time.
All research had to be approved from the top downward, and in the early 1920s THE TOP consisted of Lenin himself.
No documents bearing Lenin's signature have been unearthed regarding his approval of the Kazhinsky research.
But quite good sources hold that such documents existed, and that Lenin further approved by stating "Well, if there is some gain to be had by our great Union, then we ought to have it." Lenin's approval, whether explicit or tacit, must have come as early as 1920 -- or else no one within the Soviet hierarchy would have paid any attention to Kazhinski. And even the Brain Research Institute and the All-Russian Congress would have avoided him like the plague, as one would say.
