Scientists' Historical Misunderstandings and Academic Influences

  • Historians criticize scientists for not understanding the academic discipline of history, which predates scientific disciplines.
  • Scientists often rely on Wikipedia or biographies to understand history, lacking in-depth historical analysis.
  • James Watson's book "The Double Helix" is a mix of fact and fiction, with ongoing analysis revealing inaccuracies.
  • Watson's portrayal of Rosalind Franklin in his book has faced backlash for being misogynistic, leading to inaccurate narratives about her.
  • Matthew Cobb and Nathaniel Comfort published a paper in "Nature" correcting the history of Watson and Crick's thoughts on Franklin.
  • Scientists struggle with history due to a reluctance to abandon the Great Man Theory, which attributes historical events to exceptional individuals.
  • Francis Galton's work on eugenics, based on the hereditary genius theory, influenced the belief in biological greatness in history.

Controversial Legacy of Statistician Ronald Fisher

  • Karl Pearson, a significant figure in the field of statistics, was also a racist and supporter of eugenics, as evidenced by his statements and actions.
  • Pearson explicitly linked his statistical techniques to promoting eugenics in a lecture, showcasing his ideological alignment.
  • Ronald Aylmer Fisher, Pearson's successor, is credited with inventing many statistical techniques and is considered one of the greatest statisticians in history.
  • Fisher, a co-founder of the Eugenics Society, integrated eugenics into his work, including early descriptions of evolutionary biology concepts.
  • Fisher's book, "The Genetical Theory of Natural Selection," includes chapters on eugenics, which are often overlooked despite their significance.
  • Fisher's initial intention with the book was to focus on genetics, with eugenics chapters added later, indicating his strong interest in the subject.
  • Fisher's legacy has been reevaluated in recent years, leading to the removal of his name from awards and lectures due to his association with eugenics and controversial figures.
  • Fisher's interactions with Otmar Freiherr von Verschuer, a Nazi scientist, have raised questions about his judgment and ethics, particularly regarding his support for eugenics.
  • Fisher's frustration with his inability to influence eugenics policies led to his focus on scientific research, overshadowing his views on eugenics.
  • Fisher's removal from campuses worldwide due to his eugenics beliefs is seen as ironic, as he is criticized for the wrong reasons, such as smoking a pipe during a time when the harmful effects of smoking were becoming widely known.

Fisher's Controversial Stance on Smoking and Cancer

  • Fisher strongly opposed the idea that smoking causes cancer, using data from articles published between 1956 and 1958, including two in Nature and one review article.
  • Fisher's data, which he used to resist the notion that smoking causes cancer, was criticized for being substandard and not based on good science.
  • Ronald Fisher, a renowned statistician, vehemently opposed the idea that smoking causes cancer, despite overwhelming evidence.
  • Fisher's opposition to the link between smoking and cancer may have been influenced by his dislike of authority figures, political views, and animosity towards public health interventions.
  • Fisher's stance against the smoking-cancer link was exploited by the tobacco industry, who used his alternative theory to sow seeds of doubt about the established scientific consensus.
  • Fisher's alternative theory suggested that cancer causes smoking, based on a genetic predisposition to lung cancer and the idea that smoking alleviates an itch in the lungs.
  • Robert Proctor estimated that cigarettes are the most lethal objects ever invented, with a smoking rate equivalent to the International Space Station's speed.
  • Fisher's impact on eugenics was minimal, but his involvement in promoting doubt about smoking causing cancer had significant negative consequences.
  • Eugenics, a popular idea in the Edwardian era, involved ranking people based on biological means to improve society, leading to negative eugenic selection targeting racialized groups, disabled individuals, and others.
  • Eugenics was embraced by both left-wing and right-wing thinkers, including prominent figures like Virginia Woolf, George Bernard Shaw, and Winston Churchill, who proposed legislation based on eugenic principles.

Early Eugenics: Churchill, Roosevelt, and Sterilization

  • In 1912, Churchill proposed involuntary sterilization in the Mental Deficiencies Act, but it was removed due to MP Josiah Wedgwood's efforts.
  • America embraced eugenics earlier and more enthusiastically than the UK, with prominent figures like Teddy Roosevelt advocating for the removal of "undesirables."
  • The Eugenics Records Office, funded by wealthy philanthropists like Mary Harriman and John Rockefeller, promoted eugenics and collected family pedigrees.
  • The office organized eugenics competitions at state fairs, normalizing the idea of breeding humans for improvement.
  • America saw between 70,000 to half a million involuntary sterilizations under eugenics laws, with 31 states having such laws until 1986.
  • Gregor Mendel's work on pea plants in the 1850s laid the foundation for genetics, demonstrating predictable inheritance patterns.
  • Charles Davenport, influenced by Mendel's work, believed in single-gene inheritance for all human characteristics, like eye and hair color.
  • Davenport's oversimplified views on genetics, like eye color being determined by a single gene, have been proven inaccurate by modern research.
  • Davenport's work on ginger hair inheritance and other traits aimed to justify eugenics practices by breeding out undesirable traits.
  • Recent studies suggest that teaching Mendelian genetics first can lead to a racialized and simplified view of genetics, highlighting the need for updated education on the complexity of genetic inheritance.
