A metascientific replication project on the anomalous cognitive effect claimed by Daryl Bem (2011) was recently completed with support by the Paradox Science Institute. The tested effect concerned the anomalous ability to successfully guess the outcome of future random events. This project involved the participation of more than 26,400 participants and presents one of the largest studies in anomalous cognition ever performed. This replication project implemented advanced methodologies; that is, a combination of advanced protocols and techniques was used for reducing—simultaneously—the risk of false discoveries due to (i) confirmation bias, (ii) non-transparency, i.e., the lack of verifiability of the used research procedures, and (iii) intrinsic measurement bias. Towards this end, advanced test strategies were employed that have previously been used—successfully—to improve the reliability of findings: (1) The Advanced Meta-Experimental Protocol (AMP; Walleczek and von Stillfried, 2019), and (2) the Transparent Psi Project procedures (TPP; Kekecs et al., 2023).
