Does manifestation work?
No study has shown that thoughts attract outcomes on their own. But the question behind it ("does thinking about my goals help me reach them?") has been studied a lot, and the answer is: it depends on how you think about them.
Positive fantasies alone can sap energy
Gabriele Oettingen at New York University found in several studies that the more positively people daydreamed about a wished-for future (a new job, recovering from surgery, a crush), the less effort they tended to put in and the worse they did. In one experiment, Kappes and Oettingen (2011) found that positive fantasies lowered people's energy as measured by blood pressure. The idea: the brain enjoys the reward early.
Believing strongly in manifesting has risks
In 2023, Lucas Dixon, Matthew Hornsey and Nicole Hartley at the University of Queensland published the first scale measuring belief in manifestation (Personality and Social Psychology Bulletin). High scorers felt more successful and more optimistic about future success, but were also more attracted to risky investments, more likely to report bankruptcy, and more open to get-rich-quick offers.
What does help
Imagining the process (Pham & Taylor, 1999), contrasting the dream with the obstacle and making an if-then plan (Oettingen's WOOP; Gollwitzer's implementation intentions), and writing specific goals (Locke & Latham). Keep the part of manifesting that feels good, the clarity about what you want, and add those steps.
