An investigation of mediums who claim to give information about deceased persons

Growing public interest in the phenomenon of mediumship, particularly among bereaved persons, suggests the need for renewed controlled studies of mediums, both to provide potential clients with criteria for judging mediums and to help researchers learn whether they can produce specific and accurate information to which they have had no normal access and, if so, under what conditions. Two research studies were conducted in which mediums provided readings about particular deceased persons to a proxy sitter. The real sitters then blindly rated the reading that was intended for them along with several control readings. In the first study, the results were not significant. In the second, much larger study the results were highly significant (z = -3.89, p < 0.0001, 2-tailed). The authors discuss 2 possible weaknesses of the successful study and indicate some directions for further research.
