Of two minds: Sceptic-proponent collaboration within parapsychology.

The first author, a proponent of evidence for psychic ability, and the second, a sceptic, have been conducting a systematic programme of collaborative sceptic-proponent research in parapsychology. This has involved carrying out joint experiments in which each investigator individually attempted to mentally influence the electrodermal activity of participants at a distant location. The first two collaborations obtained evidence of 'experimenter effects', that is, experiments conducted by the proponent obtained significant results but those conducted by the sceptic did not. This paper describes a new collaborative study that attempted to replicate our previous findings and explore potential explanations for past results. The new study failed to replicate our previous findings. The paper investigates whether the results obtained in our initial studies may have been caused by a genuine psychic effect, and this third experiment failed to replicate this finding because some aspect of the study disrupted the production of that effect, or whether the results from our first two studies represented chance findings or undetected subtle artifacts, and the results obtained in the present study accurately reflect the absence of a remote detection of staring effect. The implications of this work are discussed, along with the benefits of conducting collaborative work for resolving disagreements in other controversial areas of psychology.

In vitro test of external Qigong.

BACKGROUND: Practitioners of the alternative medical practice 'external Qigong' generally claim the ability to emit or direct "healing energy" to treat patients. We investigated the ability of experienced Qigong practitioners to enhance the healthy growth of cultured human cells in a series of studies, each following a rigorously designed protocol with randomization, blinding and controls for variability. METHODS: Qigong practitioners directed healing intentionality toward normal brain cell cultures in a basic science laboratory. Qigong treatments were delivered for 20 minutes from a minimum distance of 10 centimeters. Cell proliferation was measured by a standard colony-forming efficiency (CFE) assay and a CFE ratio (CFE for treated samples/CFE for sham samples) was the dependent measure for each experiment. RESULTS: During a pilot study (8 experiments), a trend of increased cell proliferation in Qigong-treated samples (CFE Qigong/sham ratios > 1.0) was observed (P = 0.162). In a formal study (28 experiments), a similar trend was observed, with Qigong-treated samples showing on average more colony formation than sham samples (P = 0.036). In a replication study (60 experiments), no significant difference between Qigong-treated samples and sham samples was observed (P = 0.465). CONCLUSION: We observed an apparent increase in the proliferation of cultured cells following external Qigong treatment by practitioners under strictly controlled conditions, but we did not observe this effect in a replication study. These results suggest the need for more controlled and thorough investigation of external Qigong before scientific validation is claimed.

Distant healing intention: definitions and evolving guidelines for laboratory studies.

This paper provides definitions and a discussion of evolving guidelines for conducting research on the effects of distant healing intention (DHI) on living systems in the laboratory. We consider the relevance of DHI laboratory research to applied healing, special theoretical challenges, and other considerations that distinguish DHI research from other domains of laboratory science. Two sample protocols for investigating DHI are provided, one involving the human autonomic nervous system as the "target" of distant intention, and the other involving cell cultures. In essence, DHI differs from other alternative healing modalities because it postulates that mental intention alone can affect living systems at a distance, unbounded by the usual constraints of both space and time. This postulate challenges scientific assumptions that often go unexamined, including the nature of causality, the distinction between subjective and objective states, and the efficacy of double-blind protocols in controlling for experimenters' intentions. Previous laboratory research in this domain suggests that DHI effects warrant serious study, but most scientists and funding agencies are unaware of the evidence or the relevant literature. By following these evolving guidelines, researchers' designs and their ultimate publications will conform more closely to the quality standards expected by scientific journals, and such publications will in turn attract the attention of a broader range of scientists. This seems especially important for alternative healing research in general and for distant healing in particular; both realms enjoy broad public support but have largely eluded serious attention by mainstream science.
