Fantasies about the future have a troubling effect on achieving actual goals. If positive thinking doesn’t work, what does?

Excerpt from and AEON essay by Gabriele Oettingen, professor of psychology at New York University. Her latest book is Rethinking Positive Thinking: Inside the New Science of Motivation (2014)

Do you believe that positive thinking can help you achieve your goals? Many people today do. Pop psychology and the $12 billion self-help industry reinforce a widespread belief that positive thinking can improve our moods and lead to beneficial life changes. In her book The Secret Daily Teachings (2008), the self-help author Rhonda Byrne suggested that: ‘Whatever big thing you are asking for, consider having the celebration now as though you have received it.’

Yet research in psychology reveals a more complicated picture. Indulging in undirected positive flights of fancy isn’t always in our interest. Positive thinking can make us feel better in the short term, but over the long term it saps our motivation, preventing us from achieving our wishes and goals, and leaving us feeling frustrated, stymied and stuck. If we really want to move ahead in our lives, engage with the world and feel energised, we need to go beyond positive thinking and connect as well with the obstacles that stand in our way. By bringing our dreams into contact with reality, we can unleash our greatest energies and make the most progress in our lives.

Now, you might wonder if positive thinking is really as harmful as I’m suggesting. In fact, it is. In a number of studies over two decades, my colleagues and I have discovered a powerful link between positive thinking and poor performance. In one study, we asked college students who had a crush on someone from afar to tell us how likely they would be to strike up a relationship with that person. Then we asked them to complete some open-ended scenarios related to dating. ‘You are at a party,’ one scenario read. ‘While you are talking to [your crush], you see a girl/boy, whom you believe [your crush] might like, come into the room. As she/he approaches the two of you, you imagine…’

Some of the students completed the scenarios by spinning a tale of romantic success. ‘The two of us leave the party, everyone watches, especially the other girl.’ Others offered negative fantasies about love thwarted: ‘My crush and the other girl begin to converse about things which I know nothing. They seem to be much more comfortable with each other than he and I….’

We checked back with the students after five months to see if they had initiated a relationship with their crush. The more students had engaged in positive fantasies about the future, the less likely they were actually to have started up a romantic relationship.

My colleagues and I performed such studies with participants in a number of demographic groups, in different countries, and with a range of personal wishes, including health goals, academic and professional goals, and relationship goals. Consistently, we found a correlation between positive fantasies and poor performance. The more that people ‘think positive’ and imagine themselves achieving their goals, the less they actually achieve.

Positive thinking impedes performance because it relaxes us and drains the energy we need to take action. After having participants in one study positively fantasise about the future for as little as a few minutes, we observed declines in systolic blood pressure, a standard measure of a person’s energy level. These declines were significant: whereas smoking a cigarette will typically raise a person’s blood pressure by five or 10 points, engaging in positive fantasies lowers it by about half as much.

Such relaxation occurs because positive fantasies fool our minds into thinking that we’ve already achieved our goals – what psychologists call ‘mental attainment’. We achieve our goals virtually and thus feel less need to take action in the real world. As a result, we don’t do what it takes to actually succeed in achieving our goals. In multiple experiments, we found that people who positively fantasise about the future don’t, in fact, work as hard as those with more negative, questioning or factual thoughts, and this leaves them to struggle with poorer performance.

Given the relationship between positive thinking and declines in performance, does positive thinking increase a person’s chance of depression? My colleagues and I suspected as much. Researchers have shown that poor performance can give rise to symptoms of depression. In addition, psychologists have theorised that people who become depressed begin to see things in a distorted way, obsessing over negative stimuli and perceiving otherwise neutral elements in a negative way, too. Stress can trigger these cognitive biases, which otherwise lie dormant in our minds. And discovering that you have failed at achieving a goal might be all the stress you need to start seeing life in a gloomier way, thus hastening depression.
