The 1970s–1980s European debate over ganzfeld research

Record summary

Ganzfeld experiments conducted and discussed in Europe during the 1970s and 1980s tested whether sensory homogenization and relaxation might facilitate telepathic information transfer. British and European researchers contributed to the debate over sender-receiver protocols, randomization, judging procedures, sensory leakage, and replication. The lead is valuable for comparing altered-state induction with psi claims, but it is not one uniform experiment. A researcher should identify the laboratory and paper, since positive and negative results, meta-analyses, and methodological criticisms varied considerably.
