Researchers tested mediums claiming to communicate with the deceased. The study found no evidence supporting genuine mediumistic abilities, despite public interest and potential psychological implications.

Area of Science:

  • Psychology
  • Parapsychology

Background:

  • Claims of communication with the deceased by mediums attract significant public interest.
  • Such abilities, if genuine, have profound implications for psychology.
  • Previous research into mediumship has yielded mixed results and methodological debates.

Purpose of the Study:

  • To review key issues in the methodological debate surrounding mediumship research.
  • To describe a novel testing methodology designed to overcome past research limitations.
  • To empirically test professional mediums using the devised method.

Main Methods:

  • Development of a rigorous testing protocol to mitigate methodological flaws.
  • Empirical testing of several professional mediums.
  • Analysis of results to assess the validity of mediumistic claims.

Main Results:

  • The study's findings did not provide support for the existence of genuine mediumistic ability.
  • Results suggest that observed phenomena may be attributable to factors other than paranormal communication.

Conclusions:

  • The current evidence does not support paranormal claims of mediumship.
  • The developed methodology can be adapted to assess non-paranormal claims in clinical, occupational, and forensic settings.
