Since publishing “The Secret,” in 2006, the Australian author Rhonda Byrne has been writing self-help manifestos based on the idea that people who think positive thoughts are rewarded with happiness, wealth, influence, wisdom, and success. In November, 2013, she published “Hero,” the fourth book in the series. The book showcases the wisdom of twelve heroes—businesspeople, sports stars, writers, and philanthropists. Byrne’s idea isn’t new—it’s been a mainstay among greeting-card companies, motivational speakers, and school teachers for decades—but she’s become one of its most visible prophets. “The way to change a lack of belief is very simple,” Byrne writes. “Begin thinking the opposite thoughts to what you’ve been thinking about yourself: that you can do it, and that you have everything within you to do it.”
There’s some truth to Byrne’s ideas about the relationship between thought and action. New inventions emerge after their inventors struggle through years of planning and mental preparation, for example. When people have a condition called somatization disorder, their psychological or emotional distress can manifest in physical symptoms—joint pain, headaches, even seizures. Byrne is also right to emphasize the stubbornness of thought. Once you think something, it is very difficult to eradicate that idea from your mind. The late, brilliant social psychologist Dan Wegner described this as the great irony of mental control: in order to insure that you aren’t thinking about an unwanted idea, you have to continually turn your mind to that very idea. How do you know that you aren’t thinking of a white bear driving a red Ferrari unless you think about whether you’re thinking it?
The books have many adherents; most of their Amazon reviewers give them five stars. But they also have detractors. One criticism is that the books use a technique popularized by fitness gurus: when you see actors with tanned, chiseled bodies promoting a new piece of fitness equipment, you get the sense that they aren’t in excellent shape because they’ve spent hours using that particular machine. More likely, they jog or lift weights, or have great genes or a lightning-fast metabolism, or have some combination of these characteristics. It’s just as hard to believe that the heroes in Byrne’s books—let alone a feverishly productive polymath like Goethe or the notoriously irritable Beethoven—succeeded because they cultivated good thoughts. Moreover, as the journalist Oliver Burkeman noted in “The Antidote: Happiness for People Who Can’t Stand Positive Thinking,” “Ceaseless optimism about the future only makes for a greater shock when things go wrong; by fighting to maintain only positive beliefs about the future, the positive thinker ends up being less prepared, and more acutely distressed, when things eventually happen that he can’t persuade himself to believe are good.”
Burkeman is onto something. According to a great deal of research, positive fantasies may lessen your chances of succeeding.
