Opponents of GMOs might learn from the disastrous legacy of Soviet era Lysenkoism

It is rare for there to be such a wide divergence between scientific fact and public perception, but that’s the case with the debate over GMO foods.

While there is great controversy among the public concerning genetically modified food there is little in the scientific community. A 2015 survey conducted by the Pew Research Center of members of the American Association for the Advancement of Science indicated that 88% agreed that genetically modified food was safe—a higher percentage than believed that climate change was mostly human induced. The same survey also indicated that 57% of the public were of the opinion that eating GMO foods were “generally unsafe.”

To a large extent, this divergence reflects the public’s lack of understanding about the underlying principles of genetic modification and its extensive use in producing crops, medicines, vaccines and manufacturing certain foods such as cheese and beer. The public is also unaware of the environmental benefits of GMO crops. A meta-analysis of hundreds of agronomic and economic reports on GMO crops conducted by the University of Gottingen in Germany concluded that they have been responsible for a 37% decline in chemical pesticide use, a 22% rise in crop yields and a 68% advance in farmer’s profits.

Some of the public skepticism rests with a concern about broader food and farming issues, such as fears of the power of large corporations and a belief that large-scale agriculture contributes to such problems as obesity. Anti-GMO advocacy groups, which have a predisposition against GMOs because they do not fit into their ideological, political and economic view of the world, have been very successful in folding these concerns into a campaign of demonization and disinformation. What the anti-GMO organizations fail to understand, however, is that the scientific underpinnings of GMO technology are based upon evidence and not ideology.

When not politicized by special interest groups, science is an unbiased means of discovering what works and what does not. It’s theories are grounded in observation, experimentation and rigorous analysis of data. It is also subject to peer-review and must be replicated by other scientists. Like everyone else in society, scientists are entitled to hold political beliefs but science itself is not political as long as empirical evidence and transparency rule. Ideally, there is no such thing as right-wing or left-wing molecular biology or versions of plant genetics that prove or disprove the safety of GMO crops. As a result, most scientists are quite willing to alter their opinion if the evidence suggests they are wrong, their hypothesis has been disproved, a new and more comprehensive theory is devised or new information is discovered that overturns the existing scientific consensus.

Speaking practically, however, most people, including some scientists, are reluctant to change their minds and admit they are wrong or acknowledge that their thought process may be flawed. They will therefore hold onto beliefs that are not supported by rigorous evidence, which in part helps to explain many people’s unwarranted fears of GMOs. It is human nature to be afraid of things that we do not understand. This leads people to misperceive risk.

Nowhere is this more apparent than with regard to genetically modified food. There has not been one documented instance of an illness or an allergic reaction—let alone a death—resulting from genetically modified food. The reality is that many of the opponents of GMOs engage in activities that are much more hazardous than eating genetically modified food like taking unregulated untested supplements, which injures or kills thousands of people a year, or even eating at Chipotle, with its ragged food integrity system. In 2013, 32,719 people died in motor vehicle accidents, yet no one would seriously argue that cars should be banned.

The anti-GMO forces try to fit their view of science into their ideological predisposition. We have been down this road before with regard to genetics and it had disastrous consequences. In the Soviet Union during the Stalin years, the study of genetics was undermined by Trofim Lysenko and his followers because the prevailing theories of evolutionary genetics and natural selection did not fit into the official Marxist ideology.

Lysenko was an agronomist who claimed massive increases in crop yields based on plantings of just a few hectares. The exaggerations, caught the attention of Soviet officials at a time when the state run agricultural system was in a tailspin because of cold weather and the government’s collectivist policies. When Lysenko was put in charge of agricultural affairs, he denounced biologists he disagreed with, claiming they were anti-Marxist and were trying to sabotage the Soviet economy. While he administered agricultural policy, science was determined not by what was evidence based and provable but by what was politically correct. Science in other words was placed in the service of the state ideology.

As a result of Lysenko’s intimidation tactics and reign of terror, research in and the teaching of many scientific topics such as hormones, neurophysiology, cell theory, genetics and other biological disciples were banned or impeded in the Soviet Union. This had a profoundly negative impact in hindering the pursuit of scientific knowledge. It is estimated that Lysenko’s war on genetics led to the arrest, firing or execution of 3,000 biologists. Scientific research in genetics was effectively destroyed until after Stalin’s death in 1953.

Lysenkoism is now often used metaphorically to describe the ideological manipulation or distortion of the scientific process as a way to reach a predetermined conclusion, all to serve political ends. This is exactly the tactics being utilized by the anti-GMO movement. Instead of acknowledging the safety of GM crops and the cost and sustainability benefits they offer, which is the scientific consensus, they reject them out of hand; and they do so not for scientific reasons but for ideological ones.

It is dangerous to politicize science because it does not fit into one’s ideological predisposition as it can stymie basic research that can have practical applications in saving lives. This was certainly the case when the Bush Administration decided to limit federal financing of stem cell research because of religious objections from some of his supporters. Science should never be called upon to serve a narrow political agenda nor should its findings be denounced for purely ideological reasons.

The opponents of GMOs should be careful about what they wish for; demonizing GMOs is already having a chilling effect on research in genetic engineering, which has already proved to be of great importance in the development of many medicines, such as insulin, and holds great promise for the treatment of cancer. GMO applications also have great potential in vaccine research, to prevent crop loss from plant diseases, control insects that spread serious diseases, fortify existing crops with additional sources of vitamins and minerals such as Vitamin A rice, Vitamin A fortified bananas and Vitamin B6 enriched cassava, grow drought resistant crops, create disease resistant animals, to produce biofuels and clean up the environment. Do we really want to forgo these advances because of unfounded fears?

History does not have to repeat itself. Concerned but often ill-informed citizens who embrace the anti-GMO cause might benefit from reviewing the lessons of Lysenko. There is no credible peer reviewed scientific evidence that validates the notion that the process of genetically engineering seeds results in foods that are hazardous to human health or the environment. GMOs should be assessed though a scientific lens not an ideological one. Science can only be validated or disproved by rigorous research that provides convincing evidence that the prevailing scientific consensus is wrong. Rejecting a scientific principle because it does not fit into preconceived notions does not make it false; it just means that the person is stubbornly refusing to accept reality.

The opponents of GMOs might reflect on the words of Carl Sagan: “The truth may be puzzling. It may take some work to grapple with. It may be counterintuitive. It may contradict deeply held prejudices. It may not be consonant with what we desperately want to be true. But our preferences do not determine what’s true.”

  1. Utter nonsense.
    We “understand” this technology just fine and we have decided we don’t want it used for our food. There are enough people who feel this way so that the market is responding despite such power these people have over media, markets and government.
    So stop the foolish allegations such as “eat this food or we are doomed to turn into Stalanist Soviet Union. Are you f’n kidding me? Are you supposed to be the one who is so wise that we would listen to your advice about GMO?

    Once again:
    Rejection of an application of technology is not anti-science. Only an idiot would think this and I won’t listen to idiots when it comes to what I eat.
    Fears over increasing corporate control of all kinds of important things are well-founded with ample evidence of harm. For just a taste of how this happens see the TTP. Only a blind ideologue would deny this is true and I won’t listen to blind ideologues when it comes to my food.

    We don’t need this modern technology for food. We need to completely revamp our food systems to make them more modern and more in line with what people want and with what is scientifically, ethically, ecologically and economically the smart thing to do.

  2. Lysenko is responsable of the death of the great Vavilov, the person who came up with the theory of the centres of origin of plants and the centres of genetic variability. He died of hunger and illness in Siberia. A great loss to humanity.

  3. Yes, Lysenko is a classic example of someone who promises what people want to hear but then fails to deliver. Very similar in fact to the modern ‘organic’ farming sponsors. It sounds great but actually cannot deliver although organisations like The Soil Association perpetually promise that they have evidence coming ‘tomorrow’! Vavilov on the other hand ‘spoke as he found’ and suffered the consequences. Considerable parallels here with modern agricultural research!

  4. My question would be, if GMO’s are so safe, why is the health of people in the USA generally declining? Food is the one common denominator among all Americans.

    • I’d wager it’s a mix of spurious correlation and greater access to information that makes it seem like health has been generally declining.

      Beyond obesity, I don’t think the US is on that much of a decline. Many of the common health-problems are directly related to obesity. And I have a feeling that food is involved, but it isn’t a “GMO” vs. “Natural” issue – it’s likely more a combination of calorie-dense foods combined with insufficient exercise, and a healthy sprinkling of genetic per-dispositions.

      Other health metrics like life expectancy are up and cancer rates have been relatively flat across all age groups: http://www.cancer.org/research/cancerfactsstatistics/cancerfactsfigures2015/index (with the exception of specific cancer types, like lung cancer from smoking; I saw another chart many months ago that actually broke down age-group and cancer type vs. historic rates, and those were flat as well). I think we just think it’s higher now because we’re much more aware of it. Just like we all think crime is way up, when historically, it’s way, way down overall.

      • Well said, JD.

        Couple your point with recent improvements in diagnostics detecting more instances of various diseases (cases that previously weren’t diagnosed and, so, went unrecognized) and with an increasing trend by researchers to indulge self-reporting by experimental subjects (I recall a lactose intolerance study where over half of self-reported sufferers of lactose intolerance were not actually intolerant at all when medically screened for the disease — many of these healthy folks still managed to work up impressive symptoms of lactose intolerance, however, just by worrying about milk!).

        Today’s health care system tends toward inclusive diagnostic criteria almost to the point of erring on the side of false positive diagnosis. At the same time we probably have about as many hypochondriacs as ever, except now they have unfettered access via the internet to nearly limitless scary misinformation. It must truly be a stressful time to live as a hypochondriac or as an orthorexic! I try to empathize but it’s difficult given the monumental pain in the ass orthorexics and their enablers tend to be.

    • Connie, because the one common denominator in the last two decades is … Let’s see …. Ok, cell phone use. Rising cell phone use. Health declining? (Really, it isn’t, but let’s pretend it is for the sake of argument). OK, health declining. Cell phone usage going up. Bingo! Correlation! Causation!!!
      Go back to your science class papers in high school and learn about correlation and causation, dearie. You obviously flunked.

    • Actually, our health is better than ever. What do you attribute that to –eating GE food? After all, food is the one common denominator.
      ( if your premise is incorrect, your conclusion will be equally incorrect.)

    • O.k. your points are all well-taken. I’m not convinced on either side of this issue, and maybe health is “generally” getting better, but the people who brainwash us daily certainly don’t seem to have that opinion and I do realize the media, the government and big corporations use fear based tactics to keep us in line and keep us buying products. Products that contain Hydrogenated Vegetable Oil and High Fructose Corn Syrup…poison to humans, but no one who controls what is in the food seems worried about this either.

    • What measure do you have that the health of people in the US is declining? There are many healthy people in the country and life expectancy keeps increasing.
      Now I’ll make a comment based on my thoughts rather than data. I think that if Americans are concerned about their health, eating less and exercising more would have a greater impact than all the fear driven crazes.
