Previously I posted that while physicist Michio Kaku has written that telepathy is theoretically possible, how Kaku imagines telepathy is very different from how they saw it at the Duke Parapsychology Laboratory.
A few recent articles in WIRED about research into telepathy being conducted at DARPA (The Defense Advanced Research Projects Agency) and elsewhere describe a direction similar to what Kaku described in his book Physics of the Impossible (if I’m remembering what I read correctly). The main difference is J. B. Rhine and the scientists at the lab thought telepathy was non-physical, and the scientists conducting the research in these articles believe it’s a product of the brain. I think Rhine would say what they’re looking at is not telepathy but can perhaps mimic it to some extent. (Just a guess on my part.)
