Alex, Dr. J.Beischel has published some months ago a triple blind study in the journal explore, which can be downloaded:
Elsevier.
I recommend firts to read the article.
Here are some of my concerns: Cold reading may have been eliminated, but sensory cues were not. The mediums were given the first names of the discarnates, and the discarnates were paired to assure a large age difference. First names are not uniformly distributed across years, and the first name could give some (probablistic) clue to the age of the person.
Further, but not so important, the article has some statistical flaws.
So planning a new study we really have to rule out all sensory clues. That is the reason, why we need magicians (professional) and scientists (?Wiseman?) and open-minded professionals like G. Schwartz and come together.
Do we really, although the information details are incredible of some mediums. where the information comes from? Where all deatails really given by the discarnates? Super-PSI is another question.
