An interesting contrarian op-ed in The New York Times about the power of negative thinking:
Or take affirmations, those cheery slogans intended to lift the user’s mood by repeating them: “I am a lovable person!” “My life is filled with joy!” Psychologists at the University of Waterloo concluded that such statements make people with low self-esteem feel worse — not least because telling yourself you’re lovable is liable to provoke the grouchy internal counterargument that, really, you’re not.
Even goal setting, the ubiquitous motivational technique of managers everywhere, isn’t an undisputed boon. Fixating too vigorously on goals can distort an organization’s overall mission in a desperate effort to meet some overly narrow target, and research by several business-school professors suggests that employees consumed with goals are likelier to cut ethical corners.
Though much of this research is new, the essential insight isn’t. Ancient philosophers and spiritual teachers understood the need to balance the positive with the negative, optimism with pessimism, a striving for success and security with an openness to failure and uncertainty. The Stoics recommended “the premeditation of evils,” or deliberately visualizing the worst-case scenario. This tends to reduce anxiety about the future: when you soberly picture how badly things could go in reality, you usually conclude that you could cope. Besides, they noted, imagining that you might lose the relationships and possessions you currently enjoy increases your gratitude for having them now. Positive thinking, by contrast, always leans into the future, ignoring present pleasures.
The author of the op-ed, Oliver Burkeman, may simply be promoting his upcoming book, The Antidote: Happiness for People Who Can’t Stand Positive Thinking.
