The ideas Chopra promotes have regularly been criticized by medical and scientific professionals as pseudoscience. The criticism has been described as ranging \"from the dismissive to...damning\". Philosopher Robert Carroll writes that Chopra, to justify his teachings, attempts to integrate Ayurveda with quantum mechanics. Chopra says that what he calls \"quantum healing\" cures any manner of ailments, including cancer, through effects that he claims are literally based on the same principles as quantum mechanics. This has led physicists to object to his use of the term \"quantum\" in reference to medical conditions and the human body. Evolutionary biologist Richard Dawkins has said that Chopra uses \"quantum jargon as plausible-sounding hocus pocus\". Chopra's treatments generally elicit nothing but a placebo response, and they have drawn criticism that the unwarranted claims made for them may raise \"false hope\" and lure sick people away from legitimate medical treatments.
In discussing health care, Chopra has used the term \"quantum healing\", which he defined in Quantum Healing (1989) as the \"ability of one mode of consciousness (the mind) to spontaneously correct the mistakes in another mode of consciousness (the body)\". This attempted to wed the Maharishi's version of Ayurvedic medicine with concepts from physics, an example of what cultural historian Kenneth Zysk called \"New Age Ayurveda\". The book introduced Chopra's view that a person's thoughts and feelings give rise to all cellular processes.
Chopra coined the term quantum healing to invoke the idea of a process whereby a person's health \"imbalance\" is corrected by quantum mechanical means. Chopra said that quantum phenomena are responsible for health and wellbeing. He has attempted to integrate Ayurveda, a traditional Indian system of medicine, with quantum mechanics to justify his teachings. According to Robert Carroll, he \"charges $25,000 per lecture performance, where he spouts a few platitudes and gives spiritual advice while warning against the ill effects of materialism\".
Chopra's claims of quantum healing have attracted controversy due to what has been described as a \"systematic misinterpretation\" of modern physics. Chopra's connections between quantum mechanics and alternative medicine are widely regarded in the scientific community as being invalid. The main criticism revolves around the fact that macroscopic objects are too large to exhibit inherently quantum properties like interference and wave function collapse. Most literature on quantum healing is almost entirely theosophical, omitting the rigorous mathematics that makes quantum electrodynamics possible.
Physicists have objected to Chopra's use of terms from quantum physics. For example, he was awarded the satirical Ig Nobel Prize in physics in 1998 for \"his unique interpretation of quantum physics as it applies to life, liberty, and the pursuit of economic happiness\". When Chopra and Jean Houston debated Sam Harris and Michael Shermer in 2010 on the question \"Does God Have a Future\", Harris argued that Chopra's use of \"spooky physics\" merged two language games in a \"completely unprincipled way\".Interviewed in 2007 by Richard Dawkins, Chopra said that he used the term quantum as a metaphor when discussing healing and that it had little to do with quantum theory in physics.
Chopra has been criticized for his frequent references to the relationship of quantum mechanics to healing processes, a connection that has drawn skepticism from physicists who say it can be considered as contributing to the general confusion in the popular press regarding quantum measurement, decoherence and the Heisenberg uncertainty principle. In 1998, Chopra was awarded the satirical Ig Nobel Prize in physics for \"his unique interpretation of quantum physics as it applies to life, liberty, and the pursuit of economic happiness\". When interviewed by ethologist and evolutionary biologist Richard Dawkins in the Channel 4 (UK) documentary The Enemies of Reason, Chopra said that he used the term \"quantum physics\" as \"a metaphor\" and that it had little to do with quantum theory in physics. In March 2010, Chopra and Jean Houston debated Sam Harris and Michael Shermer at the California Institute of Technology on the question \"Does God Have a Future\" Shermer and Harris criticized Chopra's use of scientific terminology to expound unrelated spiritual concepts. A 2015 paper examining \"the reception and detection of pseudo-profound bullshit\" used Chopra's Twitter feed as the canonical example, and compared this with fake Chopra quotes generated by a spoof website. 153554b96e
