In today’s world, science itself, which we are constantly being told is a neutral vehicle for wholly objective ideas and theories, is increasingly being hijacked and abused by the toxic modern cult of identity politics, of both left and right. But should we be too surprised by any of this? No, because this exact same sorry process has happened time and again before, under the rule of totalitarian political cults like the Nazis and the Soviets, both of which vigorously promoted various pseudoscientific theories of ‘Aryan Science’ and ‘Marxist Science’ on the sole grounds that they were ideologically correct as opposed to being factually so.

Nazi racial pseudoscience and belief in nonsense like the ‘World Ice Theory’, which claimed that stars did not really exist and were actually just reflections of the sun off giant floating space-icebergs, were widely encouraged in the Third Reich, and used for long-term military weather-forecasting purposes. Likewise, the ideas of the renegade biologist Trofim Lysenko, who developed a deluded ‘anti-capitalist’ theory of genetics opposed to Darwin’s, were responsible for widespread famine in the USSR when Stalin allowed him to apply them practically towards the nation’s crop-harvests. Those academics and functionaries who disputed these clearly false pseudoscientific notions often found themselves in deep trouble – or, ultimately, dead.

In this incisive and challenging study, author S.D. Tucker explores the often weird and fanciful theories that were proposed and took hold under these extreme regimes – and in doing so sends a word of warning to the modern world of the internet and social media where similar bizarre ideas are expounded and consumed with frightening gullibility.

Everywhere from Western universities, schools and hospitals to Vladimir Putin’s Russia, absurd stories of sexist glaciers, racist gravity, socialist trees and NATO-backed mutant extra-terrestrial potatoes are being promoted as items of politically mandated scientific fact by compliant collaborators and credulous social media followers. Pseudoscientific narratives are even now used to justify the 2022 invasion of Ukraine, much as they were once used to justify the Nazi conquest of Europe or the spread of Communist revolution across the globe.
