Lysenkoism (Russian: Лысе́нковщина, tr. Lysenkovshchina) was a political campaign conducted by Trofim Lysenko, his followers and Soviet authorities against genetics and science-based agriculture. Lysenko served as the director of the Soviet Union's Lenin All-Union Academy of Agricultural Sciences. Lysenkoism began in the late 1920s and formally ended in 1964.
The pseudo-scientific ideas of Lysenkoism assumed the heritability of acquired characteristics (Lamarckism). Lysenko's theory rejected Mendelian inheritance and the concept of the "gene"; it departed from Darwinian evolutionary theory by rejecting natural selection. Proponents falsely claimed to have discovered, among many other things, that rye
could transform into wheat and wheat into barley, that weeds could
spontaneously transmute into food grains, and that "natural cooperation"
was observed in nature as opposed to "natural selection". Lysenkoism promised extraordinary advances in breeding and in agriculture that never came about.
Joseph Stalin supported the campaign. More than 3,000 mainstream biologists were fired or even sent to prison, and numerous scientists were executed as part of a campaign instigated by Lysenko to suppress his scientific opponents. The president of the Agriculture Academy, Nikolai Vavilov, was sent to prison and died there, while scientific research in the field of genetics was effectively destroyed until the death of Stalin in 1953. Research and teaching in the fields of neurophysiology, cell biology, and many other biological disciplines was also negatively affected or banned.
In modern usage, the term lysenkoism has become distinct from
normal pseudoscience. Where pseudoscience pretends to be science,
lysenkoism aims at attacking the legitimacy of science itself, usually
for political reasons. It is the rejection of the universality of
scientific truth, and the deliberate defamation of the scientific method
to the level of politics.
In agriculture
In 1928, Trofim Lysenko, a previously unknown agronomist, claimed to have developed an agricultural technique, termed vernalization, which tripled or quadrupled crop yield by exposing wheat
seed to high humidity and low temperature. While cold and moisture
exposure are a normal part of the life cycle of autumn-seeded winter
cereals, the vernalization technique claimed to increase yields by
increasing the intensity of exposure, in some cases planting soaked
seeds directly into the snow cover of frozen fields. In reality, the
technique was neither new (it had been known since 1854, and was
extensively studied during the previous twenty years), nor did it
produce the yields he promised, although some increase in production did
occur.
When Lysenko began his fieldwork in the Soviet Union of the 1930s, the agriculture of the Soviet Union was in a massive crisis due to the forced collectivisation of farms, and the extermination of the kulaks. The resulting famine
provoked the people and the government alike to search for any possible
solution to the critical lack of food. Lysenko's vernalization
practices yielded marginally greater food production on the farms, and
he was quickly accepted as the hero of Soviet agriculture.
Many agronomists were educated before the revolution,
and even many of those educated afterwards did not agree with the
forced collectivization policies. Furthermore, among biologists of the
day, the most popular topic was not agriculture at all, but the new
genetics that was emerging out of studies of Drosophila melanogaster, commonly known as fruit flies. Drosophilid flies made experimental verification of genetics theories, such as Mendelian ratios and heritability, much easier.
Isaak Izrailevich Prezent, a main Lysenko theorist, presented Lysenko in Soviet mass-media as a genius who had developed a new, revolutionary agricultural technique. In this period, Soviet propaganda often focused on inspirational stories of peasants
who, through their own canny ability and intelligence, came up with
solutions to practical problems. Lysenko's widespread popularity
provided him a platform to denounce theoretical genetics and to promote
his own agricultural practices. He was, in turn, supported by the Soviet
propaganda machine, which overstated his successes and omitted mention
of his failures. This was accompanied by fake experimental data
supporting Lysenkoism from scientists seeking favor and the destruction
of counter-evidence to Lysenko's theories. Instead of performing
controlled experiments, Lysenko claimed that vernalization increased
wheat yields by 15%, solely based upon questionnaires taken of farmers.
Rise
Lysenko's political success was mostly due to his appeal to the Communist Party and Soviet ideology. Following the disastrous collectivization efforts of the late 1920s,
Lysenko's "new" methods were seen by Soviet officials as paving the way
to an "agricultural revolution." Lysenko himself was from a peasant
family, and was an enthusiastic advocate of Leninism.
During a period which saw a series of man-made agricultural disasters,
he was also extremely fast in responding to problems, although not with
real solutions. Whenever the Party announced plans to plant a new crop or cultivate a new area, Lysenko had immediate practical suggestions on how to proceed.
So quickly did he develop his prescriptions—from the cold
treatment of grain, to the plucking of leaves from cotton plants, to the
cluster planting of trees, to unusual fertilizer mixes—that academic
biologists did not have time to demonstrate that one technique was
valueless or harmful before a new one was adopted. The Party-controlled
newspapers applauded Lysenko's "practical" efforts and questioned the
motives of his critics. Lysenko's "revolution in agriculture" had a
powerful propaganda advantage over the academics, who urged the patience
and observation required for science.
Lysenko was admitted into the hierarchy of the Communist Party,
and was put in charge of agricultural affairs. He used his position to
denounce biologists as "fly-lovers and people haters", and to decry the "wreckers"
in biology, who he claimed were trying to purposely disable the Soviet
economy and cause it to fail. Furthermore, he denied the distinction
between theoretical and applied biology.
Lysenko presented himself as a follower of Ivan Vladimirovich Michurin, a well-known and well-liked Soviet horticulturist. However, unlike Michurin, he advocated a form of Lamarckism, insisting on using only hybridization and grafting, as non-genetic techniques. With this came, most importantly, the implication that acquired
characteristics of an organism—for example, the state of being leafless
as a result of having been plucked—could be inherited by that
organism's descendants. This is why Lysenko claimed vernalization
would give greater productivity than it did; he believed the ability of
his vernalized seeds to flower faster and produce more wheat would be
passed on to the next generation of wheat seeds, thus causing
vernalization to further amplify the process.
Support from Joseph Stalin
gave Lysenko even more momentum and popularity. In 1935, Lysenko
compared his opponents in biology to the peasants who still resisted the
Soviet government's collectivization strategy, saying that by opposing
his theories the traditional geneticists were setting themselves against
Marxism. Stalin was in the audience when this speech was made, and he
was the first one to stand and applaud, calling out "Bravo, Comrade
Lysenko. Bravo."
This event emboldened Lysenko and gave him and his ally Prezent free
rein to slander the geneticists who still spoke out against him. Many
of Lysenkoism's opponents, such as his former mentor Nikolai Ivanovich Vavilov, were imprisoned or even executed because of Lysenko's and Prezent's denunciations.
On August 7, 1948, the V.I. Lenin Academy of Agricultural
Sciences announced that from that point on Lysenkoism would be taught as
"the only correct theory". Soviet scientists were forced to denounce
any work that contradicted Lysenko.
Criticism of Lysenko was denounced as "bourgeois" or "fascist", and
analogous "non-bourgeois" theories also flourished in other fields in
the Soviet academy at this time (see Japhetic theory; socialist realism).
Perhaps the only opponents of Lysenkoism during Stalin's lifetime to
escape liquidation were from the small community of Soviet nuclear physicists: as Tony Judt has observed, "It is significant that Stalin left his nuclear physicists alone and never presumed to second guess their calculations. Stalin may well have been mad but he was not stupid."
In other countries
Many other countries of the Eastern Bloc
accepted Lysenkoism as the official "new biology" as well; however the
acceptance of Lysenkoism was not uniform in communist countries. In
Poland, all geneticists except for Wacław Gajewski
followed Lysenkoism. Even though Gajewski was not allowed contact with
students, he was allowed to continue his scientific work at the Warsaw
botanical garden. Lysenkoism was then rapidly rejected starting from
1956
and modern genetics research departments were formed, including the
first department of genetics headed by Wacław Gajewski, which was
started at the Warsaw University in 1958.
Czechoslovakia adopted Lysenkoism in 1949. Jaroslav Kříženecký
(1896–1964) was one of the prominent Czechoslovak geneticists opposing
Lysenkoism, and when he criticized Lysenkoism in his lectures, he was
dismissed from the Agricultural University in 1949 for "serving the
established capitalistic system, considering himself superior to the
working class, and being hostile to the democratic order of the people",
and imprisoned in 1958. In 1963, he was appointed head of the newly established Gregor Mendel department in the Moravian Museum in Brno, the city in which Gregor Mendel pursued his early experiments on inheritance and formulated the laws of Mendelian inheritance.
In the German Democratic Republic,
although Lysenkoism was taught at some of the universities, it had very
little impact on science due to the actions of a few scientists (for
example, the geneticist and fierce critic of Lysenkoism, Hans Stubbe) and an open border to West Berlin research institutions. Nonetheless, Lysenkoist theories were found in schoolbooks until the dismissal of Nikita Khrushchev in 1964.
Lysenkoism dominated Chinese science from 1949 until 1956, particularly during the Great Leap Forward,
when, during a genetics symposium opponents of Lysenkoism were
permitted to freely criticize it and argue for Mendelian genetics. In the proceedings from the symposium, Tan Jiazhen is quoted as saying "Since [the] USSR started to criticize Lysenko, we have dared to criticize him too".
For a while, both schools were permitted to coexist, although the
influence of the Lysenkoists remained large for several years.
Repercussions
From 1934 to 1940, under Lysenko's admonitions and with Stalin's approval, many geneticists were executed (including Isaak Agol, Solomon Levit, Grigorii Levitskii, Georgii Karpechenko and Georgii Nadson) or sent to labor camps. The famous Soviet geneticist and president of the Agriculture Academy, Nikolai Vavilov, was arrested in 1940 and died in prison in 1943. Hermann Joseph Muller
(and his teachings about genetics) was criticized as a bourgeois,
capitalist, imperialist, and promoting fascism so he left the USSR, to
return to the US via Republican Spain. In 1948, genetics was officially
declared "a bourgeois pseudoscience"; all geneticists were fired from their jobs (some were also arrested), and all genetic research was discontinued.
Over 3,000 biologists were imprisoned, fired, or executed for
attempting to oppose Lysenkoism at one time and overall, scientific
research in genetics was effectively destroyed until the death of
Stalin in 1953. Due to Lysenkoism, crop yields in the USSR actually declined as well.
At the end of 1952, the situation started changing, possibly due
to Stalin taking offense to Lysenko's growing influence. Articles
criticizing Lysenkoism were published in newspapers. However, the
process of return to regular genetics slowed down in Nikita Khrushchev's
times, due to Lysenko showing him the supposed successes of an
experimental agricultural complex. It once again became forbidden to
criticize Lysenkoism, though it was now possible to express different
views, and all geneticists were released or rehabilitated posthumously. The ban was only waived in the mid-1960s.
Almost alone among Western scientists, John Desmond Bernal, Professor of Physics at Birkbeck College, University of London, and a Fellow of the Royal Society,
made an aggressive public defense of Lysenko and some years later gave
an obituary of "Stalin as a Scientist". However, despite Bernal's
endorsement, other members of Britain's scientific community retreated
from open support of the Soviet Union.
Neo-Lysenkoism
The word "Neo-Lysenkoism" has occasionally been used by hereditarian researchers, such as Roger Pearson and Bernard Davis, as a pejorative term in the debates over race and intelligence and sociobiology to describe scientists supposedly minimizing the role of genes in shaping human behavior, such as Leon Kamin, Richard Lewontin, Stephen Jay Gould and Barry Mehler.
Criticism
The use of the term "neo-Lysenkoism" to describe criticism of evolutionary psychology
have drawn criticism for misapplying the term "Lysenkoism" to things
unrelated to actual Lysenkoism. For instance, Lysenko's views on
inheritance of acquired characteristics presumed that individuals were
born with characteristics acquired by their parents, not tabula rasa.
For example, Stalin's purges presumed that simply having biological parents who were capitalists
constituted a risk factor for becoming a dissident. This was supposed
to be due to inheritance of acquired capitalist interest even if the
children had not been postnatally raised capitalist.
The definition of "nature" as "anything before birth" that is used by evolutionary psychologists is argued to fall into the same category when they classify ideas of hormones before birth on sexuality and empathy
as "biological." This argument would also classify Lysenkoism as
"biological" due to all three being prenatalist but not Mendelian
genetic. This approach can be used to explain that social engineering
in "nurture" models can simply be transformed into explanations from the
prenatal environment in "womb environment" models.
The usage of the term "neo-Lysenkoism" for models of evolution
that contradict the Darwinian model of gradual and maximized
reproductive success is often criticized. It is argued that since it is
uncertain whether Darwin knew about Gregor Mendel's genetic discoveries, so Darwin did not integrate Mendelian genetics into his model of evolution. Mendel read Origin of Species
and accepted evolution but did not consider his discoveries a solution
to any problems with Darwinian evolution. Hence, Mendelian genetics was
the primary subject of suppression of modern biology under Lysenkoism.
Mendelian genetics remains a source of modern criticism of the
maximization of reproductive success model of evolution, as Mendelian
models show that short term maximized reproductive success of specific
genes can deplete genetic variation and could increase the long term
risk of extinction. This is used to explain higher extinction risks in
more sexually dimorphic species as a functional similarity between Bateman's principle and asexual reproduction.
Contrary to the allegation of anti-psychiatry being neo-Lysenkoist, it is remarked that psychiatric medication
was not suppressed in the Soviet Union under Lysenkoism. The use of
psychiatric drugs in the Soviet Union actually increased and was
approved by the regime during the Lysenko era. It is cited that
Communists considered chemical imbalance models of "mental illnesses" including but not limited to anti-communism in "working class" people in Communist countries to be more materialistic, and therefore to be in accordance with Marxist dialectical materialism,
compared to other cultural factors influencíng behavior. Behavior that
was considered idealist was used as an argument by officials in the
Soviet Union for approving increased psychiatric medication.
