"The Centipede's Dilemma" is a short poem that has lent its name to a psychological effect called the centipede effect or centipede syndrome. The centipede effect occurs when a normally automatic or unconscious activity is disrupted by consciousness of it or reflection on it. For example, a golfer thinking too closely about her swing or someone thinking too much about how he knots his tie may find his performance of the task impaired. The effect is also known as hyper-reflection or Humphrey's law after the English psychologist George Humphrey (1889–1966), who propounded it in 1923. As he wrote of the poem, "This is a most psychological rhyme. It contains a profound truth which is illustrated daily in the lives of all of us". The effect is the reverse of a solvitur ambulando. Poem The poem, a short rhyme, is usually attributed to Katherine Craster (1841–1874) in Pinafore Poems, 1871. By 1881  it had begun appearing in journals such as The Spectator and Littell's Living Age. The poem later appeared in an article by British zoologist E. Ray Lankester, published in the scientific journal Nature on May 23, 1889, which discussed the work of the photographer Eadweard Muybridge in capturing the motion of animals: "For my own part," wrote Lankester, "I should greatly like to apply Mr. Muybridge's cameras, or a similar set of batteries, to the investigation of a phenomenon more puzzling even than that of 'the galloping horse'. I allude to the problem of 'the running centipede. Lankester finished the article on a fanciful note by imagining the "disastrous results in the way of perplexity" that could result from such an investigation, quoting the poem and mentioning that the author was unknown to him or to the friend who sent it to him. It has since been variously attributed to specific authors  but without convincing evidence, and often appears under the title "The Centipede's Dilemma". The version in the article is as follows : In psychology and philosophy The psychologist George Humphrey referred to the tale in his 1923 book The Story of Man's Mind: "No man skilled at a trade needs to put his constant attention on the routine work", he wrote. "If he does, the job is apt to be spoiled". He went on to recount the centipede's story, commenting, "This is a most psychological rhyme. It contains a profound truth which is illustrated daily in the lives of all of us, for exactly the same thing happens if we pay conscious attention to any well-formed habit, such as walking". Thus, the eponymous "Humphrey's law" states that once performance of a task has become automatized, conscious thought about the task, while performing it, impairs performance. Whereas habit diminishes and then eliminates the attention required for routine tasks, this automaticity is disrupted by attention to a normally unconscious competence. The philosopher Karl Popper referred to the centipede effect in his book Knowledge and the Body-Mind Problem: In Defence of Interaction: "if we have learnt certain movements so that they have sunk below the level of conscious control, then if we try to follow them consciously  we very often interfere with them so badly that we stop them". He gives the example of the violinist Adolf Busch  who was asked by fellow-violinist Bronisław Huberman how he played a certain passage of Beethoven's violin concerto. Busch told Huberman that it was quite simple — and then found that he could no longer play the passage. The psychiatric psychoanalyst Theo L. Dorpat compares questions and interventions irrelevant to the patient's current thought process during psychotherapy in his book Gaslighting to "the story of the centipede who became disorganized and unable to walk after he was asked, 'What's wrong with your 34th left foot?'." Cultural references Cover of The Hot Soldier and Other Stories by Gustav Meyrink In 1903, Simplicissimus magazine printed an adaptation of the story by the Austrian author Gustav Meyrink, "The Curse of The Toad" (Der Fluch der Kröte). The fable was also published in Meyrink's 1903 collection of tales, The Hot Soldier and Other Stories. Spider Robinson's short story "The Centipede's Dilemma" concerns a psychic who uses instinctive telekinetic powers to cheat at darts, and is foiled when another character triggers hyper-reflection in him.
