Daniel P Wirth used to be THE star amongst researchers and proponents of paranormal healing. About 15 years ago, there was nobody who had published more studies of it than Wirth. The extraordinary phenomenon was not just the number of studies, but also the fact that these trials all reported positive findings.

At the time, this puzzled me a lot. I had conducted two trials of paranormal healing myself; and, in both, cases the results had turned out to be negative (see here and here). Thus I made several attempts to contact Wirth or his co-authors hoping to better understand the phenomenon. Yet I never received a reply and became increasingly suspicious of their research.

In 2004, it was announced that Wirth together with one of his co-workers had been arrested and later imprisoned for fraud. Several of his 20 papers published in various journals were subsequently withdrawn. I remember writing to several journal editors myself urging them to follow suit so that, in future, the literature would not be polluted with dubious studies. Eventually, we all forgot about the whole story.

Recently, I took a renewed interest in paranormal healing. To my surprise, I found that several of Wirth’s papers are still listed on Medline:

Of these 9 papers, only the first one in the list carries a note indicating that the paper has been removed. In other words, 8 of Wirth’s articles are still available as though they are fine and proper.

The situation is even worse on ‘Research Gate’. Here we find all of the following articles with no indication of any suspicion of fraud:

Article: Does Prayer Influence the Success of in Vitro Fertilization-Embryo Transfer? Report of a Masked, Randomized Trial

KY Cha · Daniel P. Wirth · RA Lobo

Abstract: To assess the potential effect of intercessory prayer (IP) on pregnancy rates in women being treated with in vitro fertilization-embryo transfer (IVF-ET). Prospective, double-blind, randomized clinical trial in which patients and providers were not informed about the intervention. Statisticians and investigators were masked until all the data had been collected and clinical outcomes were known. The setting was an IVF-ET program at Cha Hospital, Seoul, Korea. IP was carried out by prayer…

Article: Multisite Surface Electromyography and Complementary Healing Intervention: A Comparative Analysis

Daniel P. Wirth · Jeffrey R. Cram

Abstract: A comparative analysis was conducted on a series of three experimental studies that examined the effect of various local and nonlocal (distant) complementary healing methods on multisite surface electromyographic (sEMG) and autonomic measures. The series concentrated sEMG electrode placement on specific neuromuscular paraspinal centers (cervical [C4], thoracic [T6], and lumbar [L3]), along with the frontalis region, due to the fact that these sites corresponded to the location of individual…

Article: Multisite Electromyographic Analysis of Therapeutic Touch and Qigong Therapy

Daniel P. Wirth · Jeffrey R. Cram · Richard J. Chang

Abstract: The influence of complementary healing treatment on paraspinal electromagnetic activity at specific neuromuscular sites was examined in an exploratory pilot study that used a multisite surface electromyographic (sEMG) assessment procedure. The study was a replication and extension of previous research that indicated that complementary healing had a significant effect in normalizing the activity of the “end organ” for the central nervous system (CNS). Multisite sEMG electrodes were placed on…

Article: Non-contact Therapeutic Touch intervention and full thickness cutaneous wounds: A replication

Daniel P Wirth · Joseph T. Richardson · Robert D. Martinez · William S. Eidelman · Maria E.L. Lopez

Abstract: The study described here utilized a randomized double-blind methodological protocol in order to examine the effect of non-contact therapeutic touch (NCTT) on the healing rate of full-thickness human dermal wounds. This study is the fifth experiment in a series of extensions based on the original research design, and is an exact methodological replication of the second study in the series. Thirty-two healthy subjects were randomly divided into treatment and control groups and biopsies were…

Daniel P. Wirth · Joseph T. Richardson · William S. Eidelman

Abstract: A series of five innovative experiments conducted by Wirth et al. which examined the effect of various complementary healing interventions on the reepithelialization rate of full thickness human dermal wounds was assessed as to specific methodological and related factors. The treatment interventions utilized in the series included experimental derivatives of the Therapeutic Touch (TT), Reiki, LeShan, and Intercessory Prayer techniques. The results of the series indicated statistical…

Daniel P. Wirth · Richard J. Chang · William S. Eidelman · Joanne B. Paxton

Abstract: The effect of Therapeutic Touch, Reiki, LeShan, and Qigong Therapy in combination on haematological measures was examined in an exploratory pilot study utilizing a randomized, double-blind, within-subject, crossover design. Fourteen subjects were randomly assigned to treatment and control conditions for two one-hour evaluation sessions separated by a 24-hour period. Six blood samples were taken from each subject — three during the treatment condition and three during the control condition —…

Article: The significance of belief and expectancy within the spiritual healing encounter

Daniel P. Wirth

Abstract: Historically, traditional cultures recognized the importance of belief and expectancy within the healing encounter and created complex rituals and ceremonies designed to elicit or foster the expectancy and participation of both the healer and patient, as well as the community as a whole. This holistic approach to health care was a fundamental component in the spiritual healing rituals of virtually all traditional native cultures. The focus of the current study was to assess the impact of…

Article: Non-contact Therapeutic Touch and wound re-epithelialization: An extension of previous research

Daniel P. Wirth · Margaret J Barrett · William S. Eidelman

Abstract: The results demonstrated a non-significant effect for the treatment versus control groups. Several factors may have contributed to the non-significance, including: the ineffectiveness of the healers, the inhibitive or dampening effect of plastic, the use of self-regulatory techniques, the dependent variable examined, the type of dressing utilized, the influence of distance, and the healers’ belief as to the effect of distance. Future studies would benefit by examining the methodological…

Article: The effect of complementary healing therapy on postoperative pain after surgical removal of impacted third molar teeth

Daniel P. Wirth · David R. Brenlan · Richard J. Levine · Christine M. Rodriguez

Abstract: This study utilized a randomized, double-blind, within subject, crossover design to examine the effect of Reiki and LeShan healing in combination on iatrogenic pain experienced after unilateral operative extraction of the lower third molar. Two separate operations were performed on 21 patients with bilateral, asymptomatic, impacted lower third molar teeth. The patients were randomly assigned to the treatment or control condition prior to the first operation. For the second operation,…

Daniel P. Wirth · Joseph T. Richardson · William S. Eidelman · Alice C. O’Malley

Abstract: The effect of non-contact Therapeutic Touch (NCTT) therapy on the healing rate of full thickness human dermal wounds was examined in a double-blind, placebo controlled study. Punch biopsies were performed on the lateral deltoid in 24 healthy subjects who were randomly assigned to treatment and control groups. Active and control treatments were comprised of daily sessions of 5 min of exposure to a hidden NCTT practitioner or control exposure. Placebo effects and the possible influences of…

DANIEL P. WIRTH · BARBARA J. MITCHELL

Abstract: The effect of Noncontact Therapeutic Touch (NCTT) therapy and Intercessory Prayer (IP) on patient determined insulin dosage was exam- ined in an exploratory pilot study which utilized a randomized, double-blind, within subject, crossover design. Sixteen type I diabetes mellitus patients were examined and treated daily by NCTT and IP healers for a duration of two weeks. Each patient underwent two separate sessions-one in the treat- ment condition and one in the control condition-with the…

What is even worse, Wirth’s papers continue to get cited. In other words, Wirth’s research lives on regardless of the fact that it is highly dubious.

In my view, it is long over-due for all journal-editors to fully and completely delete Wirth’s dubious papers. This is particularly true since several experts have alerted them to the problem. Furthermore, I submit that failing to take action  amounts to unethical behaviour which is quite simply unacceptable.
