Meta-Analysis in Parapsychology: II. Psi Domains other than Ganzfeld

ABSTRACT: The present article completes the two-part review on meta-analyses in parapsychology (for Part I, see L. Storm, 2006). The reviewed literature other than ganzfeld/autoganzfeld studies, includes meta-analyses on: (i) biological systems (DMILS), (ii) forced-choice ESP, (iii) free-response ESP, (iv) dice-throwing, (v) micro-PK (RNG), and (vi) dream-psi. Meta-analyses by T. R. Lawrence (1993), E. Haraldsson (1993), and R. G. Stanford and A. G. Stein (1994) are also reviewed. Results indicate that these meta-analyses provide considerable evidence that there is an anomalous effect in the field of parapsychology in need of an explanation. It is concluded that these and other meta-analyses in parapsychology have revealed significant non-zero effects across studies, although these tend to be rather small, but process-oriented research may further our understanding of these anomalies
