Andrew Endersby has been commenting about Dean Radin's meta-analyses for some time on this blog and elsewhere as well, and I have remarked that I would like Radin to respond.
Endersby's position is that Radin's meta-analyses are not done properly, that he does not provide inclusion criteria, and that he has left out relevant studies.
I felt that Endersby's points needed to be addressed by Radin, and asked him to do so in an email.
Radin did not wish to be drawn into a debate on this topic, but made the following points in his emails to me, which I will paraphrase.
1) Endersby's ganzfeld meta-analysis also shows staggering odds against the null hypothesis, so Radin doesn't understand the large controversy Endersby is stirring up over Radin's ganzfeld meta-analyses.
2) Radin has conducted two formal psi meta-analyses, published in the literature, and in those papers the inclusion criteria were formally outlined. Those meta-analyses covered PK experiments using dice, and PK experiments using RNG.
3) Radin's meta-analysis of the ganzfeld and his other meta-analyses (besided the two mentioned above) relied on earlier meta-analyses published in the literature, updated with data from more recent studies. They were not full, formal meta-analyses. So studies left out of earlier meta-analyses by other authors are also left out of Radin's meta-analysis updates.
4) Radin mentioned that he invited Endersby to submit his paper to a peer reviewed journal, and that if and when it gets published, he will consider the controversy important and relevant and respond. Until that happens, Radin doesn't believe that Endersby's critique rises to the level of a genuine controversy, and lacking such a controversy, Radin feels it would not be the best use of his time to respond formally.
I want to thank Dean Radin for his responses to my emails, and Andrew Endersby for bringing our attention to some important missing studies in the Radin and previous Ganzfeld meta-analyses. Andrew has also occasionally pointed out problems in my own research for AMNAP, and I appreciate his attention to detail and his penchant for rolling up his sleeves and doing his own investigations.
