Lynne McTaggart, born in New York City in 1951, is an American author, journalist, publisher, lecturer, and activist focusing on alternative medicine and consciousness. She has authored several books, including "The Field," "The Intention Experiment," and "The Power of 8." McTaggart is also the co-creator of the alternative medicine magazine "What Doctors Don't Tell You" (WDDTY).

Her work often explores concepts like the interconnectedness of the universe through a theoretical 'field' and the influence of human consciousness and intention on reality, drawing from interpretations of quantum mechanics. McTaggart also developed a personal development program called "Living The Field." Her career has involved establishing publishing companies and newsletters related to health and alternative practices. She has also faced criticism regarding the scientific basis of her claims and the content of WDDTY magazine.

McTaggart's career in publishing began with the creation of a newsletter and later the magazine "What Doctors Don't Tell You" (WDDTY), which she co-founded with her husband. This venture evolved into a public company that published various newsletters and magazines focused on alternative health and medical practices. After the company's dissolution, a new publishing entity took over the WDDTY website and other publishing activities. The magazine later shifted to a newsagent distribution model, incorporating paid advertising, a departure from its initial subscription-based approach. McTaggart has also been involved in activism, particularly concerning alternative medicine and public health discourse.

A significant aspect of McTaggart's work delves into the nature of consciousness and its connection to the physical universe, often referencing concepts from quantum physics. In her book "The Field," she proposes that the universe is unified by an interactive field. Later, in "The Intention Experiment," she discusses research suggesting that human consciousness can influence this interconnected quantum energy field. McTaggart has also developed a personal development program, "Living The Field," which is based on her interpretation of the zero-point field and its application to quantum mechanics. She has been featured in media discussing these topics, including the extended version of the film "What the Bleep Do We Know!?"

McTaggart's work and publications have drawn criticism from various figures and publications. Her stance on certain medical treatments, such as Tamiflu, has been challenged as unfounded by some critics, though research on both positive and negative effects exists. Her book "The Field" has been characterized as pseudoscience, with her understanding of quantum physics being described as a misconception. Furthermore, the magazine "What Doctors Don't Tell You" has faced scrutiny and numerous adjudications by the Advertising Standards Authority for breaches of advertising standards, including unsubstantiated and potentially harmful claims. McTaggart has also reportedly faced legal threats from distributors of WDDTY in response to criticism of the magazine's scientific rigor.
