Here are some astute observations from Anna Krylov, Department of Chemistry, University of Southern California.
AK is on target, but the peril goes far beyond science.

It’s a beautiful thing, the destruction of words.
Don’t you see that the whole aim of Newspeak is to narrow the range of thought? In the end we shall make thoughtcrime literally impossible, because there will be no words in which to express it.
–George Orwell, 1984
Figure 1. Soviet history was constantly revised to keep up with the current party line. Historic photographs were routinely airbrushed and textbooks rewritten to obliterate the canceled.(1) Left: Lenin speaking in Moscow to Red Army soldiers in 1920, with Leon Trotsky and Lev Kamenev standing to his left side, on the steps to the right. Right: Same scene, with Trotsky and Kamenev airbrushed out, after they were canceled. Once the heroes of the Revolution, they had become traitors and enemies of the people.

I came of age during a relatively mellow period of the Soviet rule, post-Stalin. Still, the ideology permeated all aspects of life, and survival required strict adherence to the party line and enthusiastic displays of ideologically proper behavior. Not joining a young communist organization (Komsomol) would be career suicide—nonmembers were barred from higher education. Openly practicing religion could lead to more grim consequences, up to imprisonment. So could reading the wrong book (Orwell, Solzhenitsyn, etc.). Even a poetry book that was not on the state-approved list could get one in trouble.
Mere compliance was not sufficient—the ideology committees were constantly on the lookout for individuals whose support of the regime was not sufficiently enthusiastic. It was not uncommon to get disciplined for being too quiet during mandatory political assemblies (politinformation or komsomolskoe sobranie) or for showing up late to mandatory mass-celebrations (such as the May or November demonstrations). Once I got a notice for promoting an imperialistic agenda by showing up in jeans for an informal school event. A friend’s dossier was permanently blemished—making him ineligible for Ph.D. programs—for not fully participating in a trip required of university students: an act of “voluntary” help to comrades in collective farms (Figure 2).

Science was not spared from this strict ideological control.(6) Western influences were considered to be dangerous. Textbooks and scientific papers tirelessly emphasized the priority and pre-eminence of Russian and Soviet science. Entire disciplines were declared ideologically impure, reactionary, and hostile to the cause of working-class dominance and the World Revolution. Notable examples of “bourgeois pseudo-science” included genetics and cybernetics. Quantum mechanics and general relativity were also criticized for insufficient alignment with dialectic materialism.
Most relevant to chemistry was the antiresonance campaign (1949–1951).(7) The theory of resonating structures, which brought Linus Pauling the Nobel prize in 1954, was deemed to be bourgeois pseudoscience. Scientists who attempted to defend the merits of the theory and its utility for understanding chemical structures were accused of “cosmopolitism” (Western sympathy) and servility to Western bourgeois science. Some lost jobs. Two high-profile supporters of resonance theory, Syrkin and Dyatkina, were eventually forced to confess their ideological sins and to publicly denounce resonance. Meanwhile, other members of the community took this political purge as an opportunity to advance at the expense of others.(7,8) As noted by many scholars,(7,8) including Pauling himself,(9) the grassroots antiresonance campaign was driven by people who were “displeased with the alignment of forces in their science”.(7) This is a recurring motif in all political campaigns within science in Soviet Russia, Nazi Germany, and McCarthy’s America—those who are “on the right side” of the issue can jump a few rungs and take the place of those who were canceled. By the time I studied quantum chemistry at Moscow State University, resonance theory had been rehabilitated. Yet, the history of the campaign and the injustices it entailed were not discussed in the open—the Party did not welcome conversations about its past mistakes. I remember hearing parts of the story, narrated under someone’s breath at a party after copious amounts of alcohol had loosened a tongue.
Fast forward to 2021—another century. The Cold War is a distant memory and the country shown on my birth certificate and school and university diplomas, the USSR, is no longer on the map. But I find myself experiencing its legacy some thousands of miles to the west, as if I am living in an Orwellian twilight zone. I witness ever-increasing attempts to subject science and education to ideological control and censorship. Just as in Soviet times, the censorship is being justified by the greater good. Whereas in 1950, the greater good was advancing the World Revolution (in the USSR; in the USA the greater good meant fighting Communism), in 2021 the greater good is “Social Justice” (the capitalization is important: “Social Justice” is a specific ideology, with goals that have little in common with what lower-case “social justice” means in plain English).(10−12) As in the USSR, the censorship is enthusiastically imposed also from the bottom, by members of the scientific community, whose motives vary from naive idealism to cynical power-grabbing.
Just as during the time of the Great Terror,(5,13) dangerous conspiracies and plots against the World Revolution were seen everywhere, from illustrations in children’s books to hairstyles and fashions; today we are told that racism, patriarchy, misogyny, and other reprehensible ideas are encoded in scientific terms, names of equations, and in plain English words. We are told that in order to build a better world and to address societal inequalities, we need to purge our literature of the names of people whose personal records are not up to the high standards of the self-anointed bearers of the new truth, the Elect.(11) We are told that we need to rewrite our syllabi and change the way we teach and speak.(14,15)
As an example of political censorship and cancel culture, consider a recent viewpoint(16) discussing the centuries-old tradition of attaching names to scientific concepts and discoveries (Archimede’s Principle, Newton’s Laws of Motion, Schrödinger equation, Curie Law, etc.). The authors call for vigilance in naming discoveries and assert that “basing the name with inclusive priorities may provide a path to a richer, deeper, and more robust understanding of the science and its advancement.” Really? On what empirical grounds is this based? History teaches us the opposite: the outcomes of the merit-based science of liberal, pluralistic societies are vastly superior to those of the ideologically controlled science of the USSR and other totalitarian regimes.(17) The authors call for removing the names of people who “crossed the line” of moral or ethical standards. Examples(16) include Fritz Haber, Peter Debye, and William Shockley, but the list could have been easily extended to include Stark (defended expulsion of Jews from German institutions),(18) Heisenberg (led Germany’s nuclear weapons program),(19) and Schrödinger (had romantic relationships with under-age girls).(19) Indeed, learned societies are now devoting considerable effort to such renaming campaigns—among the most-recent cancellations is the renaming of the Fisher Prize by the Evolution Society, despite well-argued opposition by 10 past presidents and vice-presidents of the society.(20)
There is no doubt that many famous scientists had views or engaged in behaviors that, by today’s standards, are not acceptable.(21) Their scientific legacies are often mixed; for example, Fritz Haber is both the father of modern chemical warfare and the man whose development of nitrogen fixation is feeding the planet.(22) Scientists are not saints.(21) They are human beings born into places and times they did not choose. Just as their fellow human beings do, each finds his or her way though the circumstances of their lives, such as totalitarian regimes, world wars, and revolutions. Sometimes they made the right choices, sometimes they erred. Some paid dearly for their mistakes. Haber(22) was an avid German patriot, to the extent that he actively developed chemical weapons in order to provide Germany with military advantage. Yet, his motherland rejected him because he was a Jew. He was barely able to escape Germany, and part of his extended family perished in the concentration camps. As eloquently stated by Stern in his essay,(22) are we really so morally superior that we can “judge a life by one disastrous deformation, which in some ways epitomized his and his country’s worst faults?”
Soviet history is full of examples of patriotic scientists who were imprisoned and murdered by the regime while proclaiming their unconditional loyalty to the World Revolution—one such tragic figure was Hans Hellmann, who fled Germany in 1933 (because of his Jewish wife) and, despite multiple warnings, came to Russia (because he believed in the socialist ideals), only to be executed by the Soviet regime as an enemy of the people in 1938.(23)
Some famous scientists were brave dissidents, and some were conformists and opportunists. Should we judge their scientific contributions by their political standing, the extent to which they collaborated with repressive regimes, or by how wholesome their personal lives were? The authors of the viewpoint(16) go as far as to suggest that we should use names of scientific discoveries and institutions as a vehicle to promote ideology—that is, as a propaganda tool—as was done by the Soviet, Nazi, and Maoist regimes.
The intersection of science, morality, and ideology has been studied by many scholars and historians. History provides ample evidence that totalitarian censorship of science is harmful to the progress and well-being of societies. Merton’s norms of science prescribe a clear separation between science and morality.(24) Particularly relevant is Merton’s principle of universality, which states that claims to truth are evaluated in terms of universal or impersonal criteria, and not on the basis of race, class, gender, religion, or nationality.(24) Simply put, we should evaluate, reward, and acknowledge scientific contributions strictly on the basis of their intellectual merit and not on the basis of personal traits of the scientists or a current political agenda.
Conversations about the history of science and the complexity of its social and ethical aspects can enrich our lives and should be a welcome addition to science curricula. The history of science can teach us to appreciate the complexity of the world and humanity. It can also help us to navigate urgent contemporary issues.(25) Censorship and cancellation will not make us smarter, will not lead to better science, and will not help the next generation of scientists to make better choices.
The authors of the viewpoint(16) acknowledge historic complexities and the fact that moral and ethical standards change with time. They backed off Debye’s cancellation, quoting the decisions of investigative committees that concluded that Debye did not cross the line. However, they demand that the “Shockley–Queisser limit” be renamed. They call for Shockley’s cancellation as punishment for his abhorrent views on issues far outside his domain of expertise, such as race, gender, and IQ. If, for the sake of argument, we divorce ourselves from the charged political content of Shockley’s publications on these topics, we can compare his minimal scholarly contribution in this domain to Pauling’s vitamin C debacle.(26) Should we cancel Pauling for overstepping the domain of his competence and making medically dangerous claims? Which one is the greater misconduct—publishing a paper with eugenic content or promoting vitamin C as a cure for cancer? Note that in the case of both Pauling and Shockley, the Mertonian principle of organized skepticism(24) has already taken care of effectively separating the wheat from the chaff: while Shockley’s detailed balance paper (ref 11 in the viewpoint) is cited almost 7000 times, his paper on race and IQ (ref 12 in the viewpoint) has a grand total of 15 citations.
Digging deeper into the Shockley case, many of his biographers attribute his well-documented antisocial traits and behaviors (social withdrawal and paranoia) to a mental disorder and describe him as a high-functioning autist. In his book The Gene, Mukherjee uses Shockley to illustrate the ethical conundrums of gene editing,(27) by pointing out that the same combination of genes can be both “genius-enabling” and “disease-enabling”. What if Shockley’s deplorable views were the result of his mental disorder? Should we cancel him anyway? I think we should discuss his mixed legacy and learn from his complicated story, in the same way we can learn from Fritz Haber’s and others’. These stories can teach us about the complexity of the world and of human minds, the importance of tolerance and empathy. And we should leave the Shockley–Queisser limit (and other named discoveries and equations) alone.
The issue of science moralization and censorship is older than 20th century totalitarian regimes. For example, Giordano Bruno was canceled (burned at the stake in 1600) because his cosmological views were considered to be a threat to the dominant ideology. The guardians of the truth, his prosecutors, “had the desire to serve freedom and promote the common good”.(28) A century later, Leeuwenhoek self-censored his studies and reports for offensive content (observations of spermatozoa in semen).(29,30) In 1911, Marie Curie was ostracized for immoral behavior—an affair with a married man (Langevin) following the tragic death of her husband Pierre Curie. The chair of the Nobel Prize committee, Svante Arrhenius, wrote to her advising that she not attend the official ceremony for her Nobel Prize in Chemistry in view of her questionable moral standing. Curie replied that she would be present at the ceremony, becase “the prize has been given to her for her discovery of polonium and radium” and that “there is no relation between her scientific work and the facts of her private life”.(31) Today we regard this attempt to cancel Curie on the grounds of her moral impurity as utterly absurd, yet we continue to witness the intrusion of moral arguments into the scientific domain.(31)
Examples of past cancellations done in the name of maintaining moral purity (as understood at the time) provide a useful context for today’s struggle between free speech and cancel culture. In 1952, Alan Turing was canceled for being gay. After he was convicted for “gross indecency” and subjected to chemical castration, he lost his consultancy job for the British intelligence agency, despite his vital contributions to the war effort, and was denied entry to the United States. About the same time, the University of Minnesota revoked an offer from Michael McConnell for his intent to marry another man.(32) McConnell sued, but lost, with the judge decrying same-sex marriage a “socially repugnant concept,” incompatible with holding a university position.
Today’s censorship does not stop at purging the scientific vocabulary of the names of scientists who “crossed the line” or fail the ideological litmus tests of the Elect.(11) In some schools,(33,34) physics classes no longer teach “Newton’s Laws”, but “the three fundamental laws of physics”. Why was Newton canceled? Because he was white, and the new ideology(10,12,15) calls for “decentering whiteness” and “decolonizing” the curriculum. A comment in Nature(35) calls for replacing the accepted technical term “quantum supremacy” by “quantum advantage”. The authors regard the English word “supremacy” as “violent” and equate its usage with promoting racism and colonialism. They also warn us about “damage” inflicted by using such terms as “conquest”. I assume “divide-and-conquer” will have to go too. Remarkably, this Soviet-style ghost-chasing gains traction. In partnership with their Diversity, Equity, and Inclusion taskforce, the Information and Technology Services Department of the University of Michigan set out to purge the language within the university and without (by imposing restrictions on university vendors) from such hurtful and racist terms as “picnic”, “brown bag lunch”, “black-and-white thinking”, “master password”, “dummy variable”, “disabled system”, “grandfathered account”, “strawman argument”, and “long time no see”.(36) “The list is not exhaustive and will continue to grow”, warns the memo. Indeed, new words are canceled every day—I just learned that the word “normal” will no longer be used on Dove soap packaging because “it makes most people feel excluded”(37) (emphasis mine; see Figure 3).
Figure 3. Headline of the New York Times article(37) from 2021-03-13. The word “normal” will be removed from more than 200 beauty products. “The changes were long overdue and ‘completely necessary’..., said Ateh Jewel, a beauty journalist and an advisory board member of the British Beauty Council.”(37)
Do words have life and power of their own? Can they really cause injury? Do they carry hidden messages? The ideology claims so and encourages us all to be on the constant lookout for offenses. If you are not sure when you should be offended—check out the list of microagressions—a quick google search can deliver plenty of official documents from serious institutions that, with a few exceptions, sound like a sketch for the next Borat movie.(38) If nothing fits the bill, you can always find malice in the sounds of a foreign language. At the University of Southern California, a professor was recently suspended because students claimed to have been offended by the sounds of Chinese words used to illustrate the concept of filler words in a communications class.(39,40)
Why did I devote a considerable amount of my time to writing this essay? After all, I am no fan of Shockley; his eugenic views disgust me. Notwithstanding his monumental contributions to one of the most pressing problems we face—harnessing solar energy—I would not want to sit next to him at a dinner party. Yet, the term “Shockley–Queisser limit” elicits no emotional response in me. Neither does “Stark effect”, “Haber–Bosch process”, or “Debye units”. To most scientists, these are convenient labels, which remind us that the cathedrals of science are built by mere mortals,(21) and not some deeply meaningful symbols of reverence. So why should we not humor those who claim to feel differently(16) and rename everything in sight? After all, renaming equations is even easier than renaming cities, buildings, or landmarks.
The answer is simple: our future is at stake. As a community, we face an important choice. We can succumb to extreme left ideology and spend the rest of our lives ghost-chasing and witch-hunting, rewriting history, politicizing science, redefining elements of language, and turning STEM (science, technology, engineering, and mathematics) education into a farce.(41−44) Or we can uphold a key principle of democratic society—the free and uncensored exchange of ideas—and continue our core mission, the pursuit of truth, focusing attention on solving real, important problems of humankind.
The lessons of history are numerous and unambiguous.(17) Despite vast natural and human resources, the USSR lost the Cold War, crumbled, and collapsed. Interestingly, even the leaders of the most repressive regimes were able to understand, to some extent, the weakness of totalitarian science. For example, in the midst of the Great Terror,(5,13) Kapitsa and Ioffe were able to convince Stalin about the importance of physics to military and technological advantage, to the extent that he reversed some arrests; for example, Fock and Landau were set free (however, an estimated ∼10% of physicists perished during this time(17)). In the late forties, after nuclear physicists explained that without relativity theory there will be no nuclear bomb, Stalin rolled back the planned campaign against physics and instructed Beria to give physicists some space; this led to significant advances and accomplishments by Soviet scientists in several domains. However, neither Stalin nor the subsequent Soviet leaders were able to let go of the controls completely. Government control over science turned out to be a grand failure, and the attempts to patch the widening gap between the West and the East by espionage did not help.(17) Today Russia is hopelessly behind the West, in both technology and quality of life. The book Totalitarian Science and Technology provides many more examples of such failed experiments.(17)
Today, STEM holds the key to solving problems far more important than the nuclear arms race: reversing climate change, fighting global hunger and poverty, controlling pandemics, and harnessing the power of new technologies (quantum computing, bioengineering, and renewable energy) for the benefit of humanity.
Normalizing ideological intrusion into science and abandoning Mertonian principles(24) will cost us dearly. We cannot afford it.
