They "make energy seem unnecessary" say Heather Kappes and Gabriele Oettingen. "By allowing people to consummate a desired future", the researchers explain, positive fantasies trigger the relaxation that would normally accompany actual achievement, rather than marshaling the energy needed to obtain it.
The researchers demonstrated this process across four studies. The first was the least convincing and read like a throwback to the 1960s. Women who were asked to fantasise positively about looking and feeling good in high-heeled shoes subsequently demonstrated lower energy, as revealed by their having lowing blood pressure, than did women asked to fantasise more critically about the pros and cons of wearing trendy, high-heeled shoes.
The research improved. In the second study, participants asked to fantasise positively about winning an essay contest subsequently reported feeling less energised than did participants asked to fantasise more negatively about their prospects.
Next, a positive fantasy about the coming week led participants to feel less energised, and when surveyed a week later, they'd achieved fewer of their week's goals, than had control participants who'd originally been asked to day-dream freely about the coming week.
Finally, Kappes and Oettingen highlighted the role of context, showing that positive fantasies about a pressing need are particularly de-energising. This elaborate study involved asking student participants to refrain from food and water for several hours, and then having some of them eat crackers (ostensibly as part of a taste test). For these super-thirsty participants it was a positive fantasy about a tall glass of icy water, not a fantasy about exam success, that led them to be de-energised (as indicated by a drop in blood pressure). For participants allowed to have a glass of water, by contrast, it was positive fantasies about exam success, not water, that led to them being de-energised.
Across all the studies, the researchers took pains to factor out other explanations - for example, they ruled out the effect of irritation, in case negative fantasies are energising by virtue of being irritating. They ruled out the possibility that some fantasies are easier to conjure than others. And they had a neutral fantasy condition, allowing them to confirm that positive fantasies really are de-energising, rather than it simply being that negative fantasies are energising.
So, is there any benefit to positive fantasies? From a survival perspective, if a goal, such as food or water, is unobtainable, there could be some advantage to enjoying a fantasy that switches you into a low-energy mode. Similarly, if a task fills you with dread and your short-term goal is relaxation, then indulging in positive fantasies about desired outcomes could be a way to reduce anxiety.
But ultimately, Happes and Oettingen believe that positive fantasies are likely to scupper your chances of obtaining your goals. "Instead of promoting achievement, positive fantasies will sap job-seekers of the energy to pound the pavement, and drain the lovelorn of the energy to approach the one they like," they write. "Fantasies that are less positive - that question whether an ideal future can be achieved, and that depict obstacles, problems and setbacks - should be more beneficial for mustering the energy needed to obtain success."
This study isn't the first to explode the myth of a traditional self-help tool. A 2009 paper found that repeating positive mantras about themselves led people low in self-esteem to feel worse.
