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.

Actual Paper Abstract

The term "retroactive avoidance" refers to a special class of effects of future stimulus presentations on past behavioral responses. Specifically, it refers to the anticipatory avoidance of aversive stimuli that were unpredictable through random selection after the response. This phenomenon is supposed to challenge the common view of the arrow of time and the direction of causality. Preliminary evidence of "retroactive avoidance" has been published in mainstream psychological journals and started a heated debate about the robustness and the true existence of this effect. A series of seven experiments published in 2014 in the Journal of Consciousness Studies (Maier et al., 2014) tested the influence of randomly drawn future negative picture presentations on avoidance responses based on key presses preceding them. The final study in that series used a sophisticated quantum-based random stimulus selection procedure and implemented the most severe test of retroactive avoidance within this series. Evidence for the effect, though significant, was meager and anecdotal, Bayes factor (BF10) = 2. The research presented here represents an attempt to exactly replicate the original effect with a high-power (N = 2004) preregistered multi-lab study. The results indicate that the data favored the null effect (i.e., absence of retroactive avoidance) with a BF01 = 4.38. Given the empirical strengths of the study, namely its preregistration, multi-lab approach, high power, and Bayesian analysis used, this failed replication questions the validity and robustness of the original findings. Not reaching a decisive level of Bayesian evidence and not including skeptical researchers may be considered limitations of this study. Exploratory analyses of the change in evidence for the effect across time, performed on a post-hoc basis, revealed several potentially interesting anomalies in the data that might guide future research in this area.

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.
