Speculations about the role of consciousness in physical systems are frequently observed in the literature concerned with the interpretation of quantum mechanics. While only three experimental investigations can be found on this topic in physics journals, more than 800 relevant experiments have been reported in the literature of parapsychology. A well-defined body of empirical evidence from this domain was reviewed using meta-analytic techniques to assess methodological quality and overall effect size. Results showed effects conforming to chance expectation in control conditions (...) and unequivocal non-chance effects in experimental conditions. This quantitative literature review agrees with the findings of two earlier reviews, suggesting the existence of some form of consciousness-related anomaly in random physical systems. (shrink)

We may suspect that quantum mechanics and consciousness are related, but the details are not at all clear. In this paper, I suggest how the mind and brain might fit together intimately while still maintaining distinct identities. The connection is based on the correspondence of similar functions in both the mind and the quantum-mechanical brain. Accompanying material for a talk at The Second Mind and Brain Symposium held at the Institute of Psychiatry, Denmark Hill, London on 20th October, 1990.

Confusion concerning the scientific study of consciousness is metanalysed by considering definitions of consciousness and the diversity of beliefs about consciousness and reality particularly as they are affected by information from anomalous experiences. This archival and theoretical examination reveals that the purported subjective nature of consciousness continues to create problems for its scientific study resulting in diversity in the academic community concerning the nature of consciousness. After a brief discussion in the first section of the confusion found in the literature (...) concerning consciousness, some of the referents of the term consciousness are defined in the second section. The third section consists of a summary of die results of a study by Baruss and Moore in which the disparity of versions of consciousness is related to differences in personal beliefs and purported experiences. In particular, purported anomalous experiences such as mystical experiences or out‐of‐body experiences are correlated with rejection of a physicalist interpretation of reality and a scientific mode of inquiry. Such experiences are discussed in the fourth section. It is indicated in the fifth section that the requirement for mterchangeability of observers in science has not been respected in some previous discussions of consciousness and that continued introspection of subjective experience and personal self‐exploration may be informative for a given investigator if not for everyone in the scientific community.

Being formalized inside the S-matrix scheme, the zigzagging causility model of EPR correlations has full Lorentz and CPT invariance. EPR correlations, proper or reversed, and Wheeler's smoky dragon metaphor are respectively pictured in spacetime or in the momentum-energy space, as V-shaped, A-shaped, or C-shaped ABC zigzags, with a summation at B over virtual states |B〉 〈B|. An exact “correspondence” exists between the Born-Jordan-Dirac “wavelike” algebra of transition amplitudes and the 1774 Laplace algebra of conditional probabilities, where the intermediate summations |B) (...) (B| were over “real hidden states.” While the latter used conditional (or transition) probabilities (A|C) = (C|A), the former uses transition (or conditional) amplitudes 〈A|C〉 = 〈C|A〉*. The formal parrallelism breaks down at the level of interpretation because (A|C) = |〈A|C〉|2. CPT invariance implies the Fock and Watanabe principle that, in quantum mechanics, retarded (advanced) waves are used for prediction (retrodiction), an expression of which is 〈Ψ| U |Φ〉 = 〈Ψ| UΦ〉 = 〈ΦU|Φ〉, with |Φ〉 denoting a preparation, |Ψ〉 a measurement, and U the evolution operator. The transformation |Ψ〉 = |UΦ〉 or |Φ〉 = |U−1Ψ〉 exchanges the “preparation representation” and the “measurement representation” of a system and is ancillary in the formalization of the quantum chance game by the “wavelike algebra” of conditional amplitude. In 1935 EPR overlooked that a conditional amplitude 〈A|C〉 = Σ 〈A|B〉〈B|C〉 between the two distant measurements is at stake, and that only measurements actually performed do make sense. The reversibility 〈A|C〉 = 〈C|A〉* implies that causality is CPT-invariant, or arrowless, at the microlevel. Arrowed causality is a macroscopic emergence, corollary to wave retardation and probability increase. Factlike irreversibility states repression, not suppression, of “blind statistical retrodiction”—that is, of “final cause.”. (shrink)

I address some specific problems in the two target articles offered here (Rao and Palmer/Alcock: Parapsychology review and critique), which are indicative of more general problems that plague the larger debate. Because such problems are rather typical of scientific conflict, I address general problems of assessment in a second section. In a final section. I make some comments about the future of this debate.
