The American Cancer Societies official position is that no controlled studies have produced conclusive evidence proving that hypnotherapy can help people quit smoking. They go on to say that despite the lack of clinical evidence, there does appear to be substantial anecdotal evidence that suggests it can be an effective cessation method for some people.
One study, conducted by Adam D. Galinsky and colleagues at Northwestern’s Kellogg School of Management, found that increased power tends to make one more self-centered and self-assured, but not in a good way: The researchers found that power makes one “prone to dismiss or, at the very least, misunderstand the viewpoints of those who lack authority.” High-power individuals “anchor too heavily on their own perspectives and demonstrate a diminished ability to correctly perceive others’ perspectives,” according to Galinsky and his team, adding that, “As power increases, power-holders are more likely to assume that others’ insights match their own.”
Hypnotherapy is guided hypnosis, or a trance-like state of focus and concentration achieved with the help of a clinical hypnotherapist. This trance-like state is similar to being completely absorbed in a book, movie, music, or even one's own thoughts or meditations. In this state, clients can turn their attention completely inward to find and utilize the natural resources deep within themselves that can help them make changes or regain control in certain areas of their life.
