About 16 papers are published on the internet site www.academia.edu together with rather fewer on www.ResearchGate.com, with the latter being updated when time allows. These are set out below. I have also included one early paper which was published in 1999 in the Paranormal review of the Society of Psychical Research titled: The Problem of Repeatability, or do the Laws of Nature evolve? (Paranormal Review of the Society for Psychical Research).
This Repeatability paper was interesting in that it owed its initial direction to an astonishing insight from Sheldrake contained in his second book, and which I then adapted to justify the lack of repeatability in ESP.
