"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 their swing or someone thinking too much about how they knot their tie may find their performance of the task impaired. The effect is also known as hyperreflection or Humphrey's law
after 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''.

The short poem is usually attributed to Katherine Craster (1841–1874)
in ''Pinafore Poems'', 1871. By 1881, it had begun appearing in journals such as ''

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:
:A centipede was happy – quite!
:Until a toad in fun
:Said, "Pray, which leg moves after which?"
:This raised her doubts to such a pitch,
:She fell exhausted in the ditch
:Not knowing how to run.
In psychology and philosophy
English psychologist
George Humphrey (1889–1966) 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, his eponymous "Humphrey's law" states that once 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

unconscious competence.
In 1994, 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 violinist

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?'."
