Plain English Summary

This paper is a pointed rebuttal after Radin and colleagues tried to defend their double-slit consciousness experiment. The authors lay out a damning case: when they ran a carefully controlled replication with encrypted data, they found a significant false alarm in the equipment but nothing where the "real" consciousness effect was supposed to show up. They also catch Radin's team engaging in HARKing β€” that's "Hypothesizing After Results are Known," basically changing your predictions after peeking at the answers, which is a big no-no in science. Two specific instances are documented: a statistical test falsely labeled as pre-planned and a last-minute switch to a different analysis strategy after unblinding. Perhaps most tellingly, three independent research groups all reached the same conclusion: this experiment is prone to producing false discoveries, especially when researchers go fishing through data after the fact.

Research Notes

Key skeptical contribution to Controversy #4 (double-slit/quantum PK). Documents specific methodological problems β€” HARKing, false positives, and inadequate controls β€” in the Radin DS-experiment paradigm. One of several critical papers challenging the reliability of the most-cited mind-matter interaction experiment in this library.

Response to Radin et al.'s (2020) commentary defending the Radin double-slit experiment on observer consciousness. A funder-commissioned replication using an advanced meta-experimental protocol (AMP) with data encryption found a significant false-positive effect (p = 0.021, Οƒ = βˆ’2.02, N = 1,250 trials) but no significant effects where Radin had predicted true positives. Documents two instances of HARKing by Radin et al.: (1) a chi-square test falsely claimed as pre-specified was actually post-hoc, and (2) a call for multiple-testing correction that abandoned the planned predictive single-testing strategy after unblinding. Three independent sources (Guerrer 2019, Tremblay 2019, Walleczek & von Stillfried 2019) converge on the conclusion that the Radin DS-experiment is prone to false discoveries, particularly with post-hoc analyses.
