How lysenkoism became pseudoscience: dobzhansky to velikovsky.

Area of Science:

• History of Science
• Genetics
• Philosophy of Science

Background:

• T. D. Lysenko's neo-Lamarckian hereditary theories gained prominence in the 1940s.
• These theories evolved from disputed doctrines to a widely recognized example of "pseudoscience."
• The Stalinist state's endorsement of Lysenko's doctrines in August 1948 marked a significant turning point.

Purpose of the Study:

• To explore the historical context and reasons behind Lysenkoism's classification as pseudoscience in America.
• To examine American strategies employed to refute Lysenkoism, both before and after the 1948 Soviet endorsement.
• To compare the Lysenko case with the Immanuel Velikovsky scandal as instances of alleged pseudoscience.

Main Methods:

• Analysis of American efforts to combat Lysenkoism, including the translation work of Theodosius Dobzhansky.
• Enumeration of various tactics used to challenge theories perceived as pseudoscientific.
• Comparative analysis of the Lysenko case with Immanuel Velikovsky's "Worlds in Collision".

Main Results:

• Lysenkoism's transformation into a prime example of pseudoscience was influenced by specific historical and political contexts.
• American scientific communities developed and employed diverse strategies to refute Lysenko's theories.
• The characterization of Lysenkoism as pseudoscientific provided a framework for categorizing other controversial scientific ideas, such as Velikovsky's.

Conclusions:

• The label of "pseudoscience" applied to Lysenkoism had significant implications for scientific discourse and the rejection of alternative theories.
• The Lysenko case and the Velikovsky scandal highlight the complex interplay between scientific validity, political influence, and public perception.
• Understanding these historical cases offers insights into how scientific ideas are accepted, rejected, and labeled within society.
