Plain English Summary

Can people unconsciously dodge unpleasant images before they appear? Five European labs teamed up with pre-registered methods — no wiggle room for fudging. Over 2,000 participants made quick choices while a quantum random number generator picked nasty or neutral pictures. The verdict? A clear no. Bayesian analysis (a method weighing evidence for versus against a claim) found moderate-to-strong evidence against retroactive avoidance, with an effect size of essentially zero. Researchers did spot curious wave-like time patterns inspired by Generalized Quantum Theory, but that was entirely after-the-fact — more "huh, interesting" than "case closed." The best-designed null result in the precognition debate so far.

Research Notes

The only high-powered, preregistered replication using a fast-thinking protocol in the precognition/retroactive avoidance literature. Key evidence for the Bem Feeling the Future debate — a well-designed null result from sympathetic researchers. Authors' exploratory GQT-based temporal analyses are theoretically novel but entirely post hoc.

Preregistered, multi-lab replication of Maier et al. (2014, Exp. 4) testing retroactive avoidance — unconscious anticipatory avoidance of randomly selected future aversive stimuli. Across five labs in Germany, Italy, Russia, France, and Sweden (N=2,004), participants completed 60 binary key-press trials with quantum-based random stimulus selection and masked picture presentation. Sequential Bayesian analysis yielded BF01=4.38, moderate evidence against retroactive avoidance. Wider priors produced BF01>30. Meta-analytic effect size across labs was ES=0.008 (p=.76) with negligible heterogeneity. Exploratory temporal analyses combining original and replication data (N=2,328) found non-random oscillations in the sequential BF curve, consistent with Generalized Quantum Theory predictions.
