Lynne McTaggart (born 23 Jan 1951, New York) is an American journalist, author, publisher and lecturer, now living in London. According to her author profile, she is a spokesperson "on consciousness, the new physics, and the practices of conventional and alternative medicine". McTaggart is the author of six books, including The Intention Experiment and The Field.
In her autobiography, McTaggart reports that she had an illness and identified "a toxic yeast" as the cause. Then, in conjunction with a homeopathic doctor, she developed a special diet that she says cured it. As a result, her husband, Bryan Hubbard, suggested that McTaggart write a newsletter on the risks of some medical practices and he devised the title: "What Doctors Don't Tell You". In 1996, McTaggart published a book using the same name. She also published a "What Doctors Don't Tell You" handbook criticizing childhood vaccinations in 1992 and a cancer handbook, which was updated in 2000.
She and her husband set up a public company in 2001, What Doctors Don't Tell You plc, later Conatus plc, which published newsletters, magazines and audio-tapes based on conferences and seminars including, What Doctors Don't Tell You, PROOF!, and Living the Field. The company was wound-up in 2009.
A new company, Wddty Publishing Ltd, run by McTaggart and her husband, took over the What Doctors Don't Tell You website, and New Age Publishing Ltd was created for McTaggart's other publishing and public speaking activities. Publication of their monthly magazine What Doctors Don't Tell You restarted in August 2012 aimed newsagent and high street distribution, instead of the previous subscription model.
McTaggart says about the relationship of the medical industry and the public: "the roles are the reverse of what many people think: we debate with fact against an establishment which argues with emotion."
In her book The Field, McTaggart discusses scientific discoveries that she says support the theory that the universe is unified by an interactive field. The book has been translated into fourteen languages. In a later book, The Intention Experiment, she discusses research in the field of human consciousness which she says supports the theory that "the universe is connected by a vast quantum energy field" and can be influenced by thought. This book has been translated into eighteen languages.
McTaggart has a personal development program called "Living The Field," which is based on an interpretation of the zero point field as applied to quantum mechanics. She appears in the extended version of the movie What the Bleep Do We Know!?, as well as the movie, The Living Matrix - The Science of Healing.
From 1996 until 2002 McTaggart and Hubbard published the monthly newsletter Mother Knows Best, later renamed Natural Parent magazine, focusing on home schooling, environmental and health concerns, including nutrition and homeopathy. They also published related books: My Learning Child, My Spiritual Child and My Healthy Child.
McTaggart became the victim of a major act of plagiarism when significant portions of her book about Kathleen Cavendish, Marchioness of Hartington appeared without attribution or permission in The Fitzgeralds and the Kennedys: An American Saga, by popular historian Doris Kearns Goodwin. Goodwin eventually resolved the matter with a public apology to McTaggart and a substantial monetary settlement.
What Doctors Don't Tell You has been cited for factual errors in their attacks on medicine, such as confusing the antiviral drug Tamiflu for a vaccine and attributing deaths to a nonexistent avian influenza vaccine. Ben Goldacre has described McTaggart as "viciously, viciously anti-vaccine" and notes that "In a radical move, even for the vaccine fear-mongering community, this time she has people dying from a vaccine that doesn’t actually exist".
McTaggart was reported to have threatened to sue Simon Singh after he contacted Comag, the distributors of WDDTY, complaining that the magazine was "largely unscientific" and "promoting advice that could potentially harm readers." "Also, many of the adverts appear to make pseudoscientific and unsubstantiated claims," he said. "I even offered to meet with Comag and introduce them to medical experts, but they have not accepted this invitation. When I suggested that I would blog about our email exchange, their reaction was to tell me in no uncertain terms: 'I should inform you that we have sought legal advice in respect of this matter. We would take any attempts to damage our reputation on social media or elsewhere very seriously.'"
In the months between first publication of What Doctors Don't Tell You in magazine form, and February 2013, 54 breaches of the Code of Advertising Practice in 11 adverts were adjudicated and upheld by the Advertising Standards Authority along with a further 11 informally resolved cases, concerning adverts in the first two issues.
In an interview on BBC Radio 4, GP and author Dr. Margaret McCartney stated: "I'm astounded that Lynne thinks this is an evidence-based publication. It's anything but," she said. "The problem with evidence is that it can tell you things that you'd rather not know. A lot of the time medicine does do harm but that's why doctors and scientists are duty-bound to put their research findings out there and to stop doing things that cause harm. What we shouldn't do is abandon medicine and the scientific method and go straight for alternative medicine with no good evidence that that works either." She criticised stories in the magazine as "absolute rubbish" and "ridiculously alarmist".
In an article in The Times in October 2013 Tom Whipple, Science Correspondent, said that "Experts are calling on high street shops to stop selling a magazine that claims that vitamin C cures HIV, suggests homeopathy could treat cancer and implies that the cervical cancer vaccine has killed hundreds of girls"
