Sounds really interesting!!
Recently a detailed investigation of the genuineness of mediumship was carried out by Professor Gary Schwartz and colleagues at the University of Arizona. Using well known mediums George Anderson and John Edward and lesser known mediums S.Northrop, L. Campbell and A. Gehman doing double blind studies they found that the mediums were very accurate, to a degree far in excess of chance. The full first study was published in the Journal of the Society of Psychical Research in England in January, 2001.
