Remote Viewing: a 1974–2022 systematic review and meta-analysis

After more than 50 years of investigation into extrasensory perception, remote-viewing experimental protocols appear to be the most efficient for both experimental and practical applications.

Dr. Patrizio Tressoldi will share results of the  first meta-analysis of all studies related to remote-viewing tasks conducted up to December 2022.
After applying our inclusion criteria, we selected 36 studies with a total of 40 effect sizes. Both frequentist and Bayesian meta-analyses revealed a strong average effect size of .34; 95% confidence intervals: .22 -.45, after the exclusion of outliers, without signs of publication bias and a tiny decline effect. In the raw scores, these average results correspond to a difference in hits score of 19.3%; 95% confidence intervals:13.6%–25%, above the expected chance. Among the meta-analyses of moderators, a small nonstatistical difference emerged between the precognitive and clairvoyance tasks, particularly for those with an outbound agent. A comparison with meta-analytical results observed with other experimental protocols testing extrasensory perception showed the clear superiority of remote viewing.
