Meta Spirituality · Trial 3
One reading, and the weight of their problems fell by two thirds.
Two thousand and four people took part in the largest randomized trial ever run on a self-help book. Half read The Meta Self once and half did not. The readers were not taught to manage their problems better, and their problems did not have to be solved one by one. What fell was how heavy those problems felt, along with the anxiety that came with them, and the effects were still in place a month later.

ITEM BY ITEM
Every question, ranked by how much it moved.
Each scale is built from individual questions, and these are the reading group’s average changes from before to after. The burden and anxiety items are shown first, where a decrease means improvement.

Full results
Every outcome, every timepoint
Group means at each measurement. EG is the reading group and CG the control group. The controlled effect size adjusts for baseline, and every p-value reflects the between-group comparison.
Nobody solved their problems. The problems stopped weighing what they weighed.
How to read this
The problems did not go anywhere. The burden did.
Nothing in the trial addressed anybody’s circumstances. No one was given advice, a plan, or a technique for handling a difficult marriage, a job or a diagnosis, and two weeks is not long enough for a life to rearrange itself. What the scale measured is how heavily daily difficulties pressed on the person carrying them, and that fell by roughly two thirds after a single reading. The clearest items say it plainly: people stopped feeling that difficulties were piling up beyond their control, and stopped feeling that they could not cope with everything. The control group eased a little on its own while simply waiting, which is ordinary expectation and time, and the distance between the two groups is what the reading produced.
Method note.
Participants were randomly assigned to read The Meta Self or to a waiting control, with assessment at four points: before reading, immediately after, at day 7 and at day 30, with the control group assessed through day 7. Retention in the reading group was 92% at day 30. Effect sizes are Cohen’s d, where the controlled d is the ANCOVA between-group estimate adjusting for baseline, and within-group percentages describe the reading group’s change from before to after. The preregistration is published at doi.org/10.17605/OSF.IO/VRP52. Individual results vary, and a group result is never a promise of an individual outcome.
