Self-experimentation - History

History

Sanctorius of Padua was probably the first documented case of self-experimentation—living on a balance for 30 years in the early 17th century, weighing himself, his daily food, liquids, and combined excretions, leading him toward the discovery of metabolism

Human scientific self-experimentation principally (though not necessarily) falls into the fields of medicine and psychology, broadly conceived. Self-experimentation has a long and well-documented history in medicine which continues to the present. In psychology, the best known self-experiments are the memory studies of Hermann Ebbinghaus, establishing many basic characteristics of human memory through tedious experiments involving nonsense syllables.

Recently, Dr. Seth Roberts and Dr. Allen Neuringer have advocated the broader use of self-experimentation, arguing that its low-cost and ease (compared to traditional large-sample experiments with human subjects) facilitate conducting a very large number of experiments, testing many treatments and measuring many things at once . This allows considerable trial and error and can lead to the generation and testing of many ideas. Self-experimentation provides superior evidence to mere anecdotal evidence, because the entire experimental is explicitly designed to test a hypothesis, but is subject to observer bias. Self-experimentation could be considered a useful adjunct to large-sample experiments in scientific research.

Famous quotes containing the word history:

    The greatest horrors in the history of mankind are not due to the ambition of the Napoleons or the vengeance of the Agamemnons, but to the doctrinaire philosophers. The theories of the sentimentalist Rousseau inspired the integrity of the passionless Robespierre. The cold-blooded calculations of Karl Marx led to the judicial and business-like operations of the Cheka.
    Aleister Crowley (1875–1947)

    When the history of guilt is written, parents who refuse their children money will be right up there in the Top Ten.
    Erma Brombeck (20th century)

    [Men say:] “Don’t you know that we are your natural protectors?” But what is a woman afraid of on a lonely road after dark? The bears and wolves are all gone; there is nothing to be afraid of now but our natural protectors.
    Frances A. Griffin, U.S. suffragist. As quoted in History of Woman Suffrage, vol. 4, ch. 19, by Susan B. Anthony and Ida Husted Harper (1902)
