Objective: The aim of this study was to assess the results of all meta-analyses on anomalous cognition conducted between 1989 and 2021 in order to find moderators associated with greater effect sizes.Method: We included all meta-analyses of studies related to anomalous cognition published up to 2021.Results: Our dataset, accumulated over itsmajorlook.com more than 80 years of investigation, refers to 11 meta-analyses related to six different states of consciousness.The evidence clearly shows that anomalous cognition seems possible and its effects can be enhanced by using a combination of some non-ordinary or read more altered states of consciousness (e.g.
, dreaming, ganzfeld, etc.), coupled with free-response procedures, or neurophysiological dependent variables.These conditions facilitate an alternative form of cognition seemingly unconstrained by the known biological characteristics of the sense organs and the brain.Conclusion: The accumulated evidence expands our understanding of the mind-brain relation and the nature of the human mind.
