Feeling the Future Again: Retroactive Avoidance of Negative Stimuli

📌 Appears in:

Plain English Summary

Can people unconsciously dodge bad experiences that haven't happened yet? A European team ran seven controlled experiments where people pressed keys, then were shown unpleasant images tied to one choice. Four studies found people slightly avoided the key linked to future nastiness. Pooling nearly 3,000 participants, the effect was small but statistically solid, with Bayesian analysis (a method for weighing evidence) at nearly 300-to-1 favoring something real. This work began before the researchers even knew about Bem's famous precognition experiments, making it a genuinely independent replication of one of parapsychology's most controversial claims.

Actual Paper Abstract

During the past decades, several theories have been proposed that relate quantum mechanics to information processing in the human mind. These theories predict that the arrow of time has no direction during unconscious processing states. Across 7 experiments, we tested whether masked negative stimuli presented in the future lead to an unconscious avoidance reaction in the present. Response registration took place about 500 milliseconds before stimulus onset. In the majority of the studies the predicted retroactive influence was found. On average, participants were able to unconsciously avoid negative future outcomes (mean ES = 0.07; Combined Bayes factor = 293). These results are in line with similar precognitive avoidance effects recently reported by Daryl Bem in 2011 (Experiment 2). The reported findings are discussed with regard to the proposed quantum model of the mind. We also highlight the limitations of our research.

Research Notes

Independent European replication of Bem (2011) Exp 2, begun before awareness of Bem's work. Currently misplaced in 10_Skeptical_and_Critical despite reporting positive precognition results. The mixed pattern (4/7 significant) and prior-dependent Bayesian evidence are central to the Bem precognition controversy.

Seven double-blind experiments investigated whether masked negative stimuli presented 500 ms after a response could retroactively influence unconscious key-press selections, as predicted by the Orch-OR quantum-mind model. Using IAPS images and a simultaneous two-key press paradigm, four of seven studies found significant avoidance of negative future outcomes (Study 1: N=111, d=0.25; Study 2: N=201, d=0.21; Study 3: N=1222, d=0.07; Study 4 with quantum RNG: N=327, d=0.10). A meta-analysis across all seven experiments (total N≈2,970) yielded ES=0.07, z=3.79, p < .0001, with a combined Bayes factor of 293 favouring retroactive influence.
