NURSE MARTHA ROGERS -a critical look by Robert Glickman

Martha Rogers was a famed and respected theorist of Nursing. She was based at New York University's School of Nursing and a major supporter of Therapeutic Touch (TT) especially in its formative days of its development in the early 1970s. TT's co-creators are Dolores Krieger, RN , Ph.D. and Dora Kunz, a "fifth generation sensitive" and clairvoyant since birth, who was, at this time, the president of the American Theosophical Society. Krieger's initial forays into research keyed on the laying on of hands to elevate hemoglobin levels in afflicted individuals (Krieger 1972). Soon Krieger would state that Prana, Hinduism's "vital force," was the source of the healing in TT. After receiving much condemnation and criticism from her third hemoglobin study, Krieger dropped the Prana explanation and embraced the human energy field (HEF) concept then being developed by Rogers. (Rosa 1994)

It was convenient that as Krieger was looking for a more scientific rational for TT, Rogers was introducing her Science of Unitary Human Beings (SUHB). This "science" included concepts as the unitary man, "Homo Spacialis" (the next evolutionary plateau for humankind - humans in outer space), pandimensionality, transcendence and a host of other unsubstantiated abstractions. "From the science of unitary human beings, Rogers has derived the theory of paranormal phenomena. This theory posits that in a pandimensional, unitary world there is no linear time and no separation of human and environmental fields. This theory provides and explanation for phenomena such as clairvoyance and telepathy and for the process and outcomes of interventions which need not involve physical contact, such as therapeutic touch. According to this theory, action-at-a-distance phenomena are normal rather than paranormal." (Meehan 1993)

Rogers' SUHB gave Krieger a theoretical background for TT and TT gave Rogers an alleged physical manifestation for her "science." Later a flawed study by another Nursing theorist, Janet Quinn, proved to believers that TT was effective and that actual touch was no longer necessary. (Quinn 1982) From this point, TT became more accepted in the nursing hierarchy.

One of the many places to look for potential TT practitioners was on the Internet. I submitted the TT challenge to the Nurse Rogers e-mail service. This service is run by Rogers devotees and focuses on various aspects of Nursing from a Rogerian perspective. I informed them that the test was to be conducted at the JREF Building in Ft. Lauderdale, Florida on June 2, 3 & 4, 1997. Best of all, the judge of the test would be PBS's Scientific American Frontiers TV program. The test would use a fiberglass construct that has two sleeves and that allows for the insertion of a subject's arms. After a random coin-flip, the TT practitioner would assess the energy emanating from the construct to determine whether the right or left sleeve was occupied. After some preliminary trials, a score of 15 or greater out of 20 would be considered a positive result and would allow that practitioner to advance to the final test. This final test would be done the following day and a score of 20 out of 20 in would win the $1,100,000 award. For the most part, the invitation wasn't well received.

Francis C Biley RN, Ph.D. of University of Wales College of Medicine is a contributing author of The Theory and Practice of Therapeutic Touch (1995 Churchill Livingstone) and Coordinator of the International Region of the Society of Rogerian Scholars. She is also the list owner of the Nurse Rogers service. She stated, "After spending some time on formulating a critique of the methodology for the following quasi- experiment, I have decided that it really isn't worth doing. Although I applaud Glickman and associates for spending time on the subject, it is quite obvious that they need to expand their methodological understanding beyond 'if you can't measure it, it doesn't exist.'"

Ana Cris da Sal is an RN and Nursing researcher in Brazil. She wrote, "I am getting skeptic (sic) by the skeptic methods. They seem to be so... hmmm....antique ?! A researcher, a REAL one, before accepting or not the phenomenon, should study it (by modern methods, of course). TT, for instance, should be tested besides Quantum Physics and Physiology - and that's exactly what I am doing in my PhD research. I'll be pleased to win the prize - proving OR NOT (as a REAL researcher must think) the existence of the human energetic field. And if I don't many others will be developing parallel studies, as the pandimensional universe provides uncountable opportunities and phenomenon."

Joanne Griffin is a TT researcher from Martha Rogers' homebase New York University. She wrote, "I almost treat messages like the one from Mr. Glickman like the jokes which I usually enjoy enormously and often forward to my friends. It seems obvious to me that he does not understand the basic definition of energy field as Rogers used(s) the term, and it isn't worth the time to respond."

I responded to these rather negative outlooks of my work with the following: "Pardon me for what I now see as an intrusion, meaning the posting of the TT challenge. I thought this was an open board with people open to new ideas. I didn't realize that material was to be screened prior to posting. I will be the first to admit that the most appropriate place to post this would be a TT e-mail service. The problem is that I do not know of any. However, do to the close relationship of the two concepts and in the interest of good science and Nursing, I still thought it appropriate to post here. Most of all, with the cameras of Scientific American Frontiers, I thought TT proponents would appreciate the chance to prove to the waiting world that TT's HEF exists

..

"Some of the recent responses point out one of the main problems with Rogerian Science which is the duality and elusiveness of simple meanings . All to often, much discussion on these postings is devoted to the defining of concepts. The term 'human energy field' sometimes refers to the TT HEF in a Rogerian context and sometimes it doesn't. It seems to depend on the convenience of the author at the given time. However, most of the writers in this service seem to accept the notion of the TT concept and its HEF. In fact many have devoted research to it.

"The focus of this our TT study is to take TT back to its most basic concept. 'Can a TT practitioner (TTP) feel an energy field?' This is a highly testable claim that they perform on a daily basis. I fail to see the objection to this simple premise or why 'it really isn't worth doing ." Best of all, it doesn't need extremely large sample groups, complicated procedures, extreme methodological strategies and statistics or even quantum mechanics. It's a simple test that I highly recommend to all of the TTPs to try on their own.

"So it is not an 'if you can't measure it, it doesn't exist' notion we are working on here. TTPs have made the claim that they feel energy fields. We simply designed a test to see if they can. This is the way skeptics work. When someone makes a claim, we keep an open mind and study it. Then a fair experiment is devised to best test the claim. A closed minded person would simply dismiss it out of hand (much like they way some people on this board have dismissed our test and even called it a 'joke').

"I feel that this is important research in spite of the fact that it may seem too simplistic to some. Had research such as this been done in the infancy of TT and Rogerian science, maybe this challenge wouldn't be necessary now."

Biley, at this point, encouraged me to keep on posting. She also agreed about the duality and elusiveness of simple meanings and that Rogerian discussion spends a lot of time defining concepts. "I sometimes wish that they (we/me/us) could just get on with it, but then I think its the beginning of an evolving science and there is much we don't yet understand."

At this point, I thought I had my foot in the door. "I am glad you see my point about the elusiveness of definitive meanings for terms in Rogerian science and that there is much that is not yet understood. So this is why I am sure that you know that it is important to follow the scientific method. Although it can be rigid and systematic, it is this way for a reason. This is to eliminate error which can be introduced by anything including improper technique, wishful thinking, bias and even intentional deceit.

"So in an evolving science, the scientific method is even more important . It prevents confusion and the contradiction of terms. After a hypothesis is made, tests are conducted to check that hypothesis. The evidence and data are analyzed. The hypothesis is either accepted or rejected. These are the steps and building blocks of scientific knowledge.

"In Rogerian science, most concepts are beyond testing. Those that are testable, aren't tested. Other studies (especially ones involving TT) are too convoluted and not properly controlled. True double-blind studies seem not to exist. You can't add to the body of knowledge by building untested hypotheses on top of other untested hypotheses. The end result is a jumbled mix of concepts and terms that people can't properly define or apply any useful or practical meaning.

"When something is testable, it must be tested. When people go out of their way not to test the certain claims, something is wrong. Again, this test is designed to show the public through PBS's Scientific American Frontiers TV program that a TT practitioner can feel an energy field. Surely, someone reading these notes is either able to do this or knows someone who can."

Martha H. Bramlett, RN, Ph.D., in an effort to try to bring some perspective to the discussion, added this: "Let me state for the record that I am not a therapeutic touch practitioner. While I taken classes and have used it one occasion (and my recipients have reported positive results), I certainly do not place myself in the class with some of the experts that have participated in this discussion. Nor do I always claim to get Rogerian theoretical perspectives always correct. Like all of us, I am evolving and striving for greater knowledge. So I hope all parties will forgive me for any errors (and provide me insights so I can learn).

"The crux of this issue seems to be one in which sciences are clashing. Mr. Glickman is making a sincere effort to try to understand a purported phenomenon. His motivation may be to prove or disprove the phenomenon, but I think the effort is still sincere or he would not put so much effort into it. Yet when presented to the Rogerian Science Nursing community, the effort has met with great consternation. Several things contribute to this. First, the term Therapeutic touch is somewhat imprecise since Rogerian Therapeutic touch (as pioneered by Dr. Krieger) has a very different theoretical base than that presented by many of those who report themselves to be therapeutic touch practitioners. Thus, when Mr. Glickman says therapeutic touch, we don't even know if we're talking about the same thing, and in fact from the discourse, I feel sure we're probably not.

"Many have tried to explain this difference, however, if each of us remember back to when we first started working with Rogerian Science, we will probably all remember the struggle we endured to hone the conceptual picture involved. Our conceptual perspective dictates what we see, and sometimes limits our abilities to see through another perspective. Science is replete with examples of this. Einstein altered his formulas because his belief in a static universe was so compelling, he couldn't believe his own calculations, and he later admitted this...

"The question arises as to what constitutes scientific investigation. I think many of the therapeutic touch practitioners and Rogerians scientists have tried to explain to Mr. Glickman that his tests are inappropriate for the phenomenon to be tested...

"I think this is the crux of the discourse between Mr. Glickman and the 'Rogerians.' The energy field he is trying to measure is not the one we're saying we feel. Perhaps at some point such a measure will exist, but not right now. So I would ask Mr. Glickman to be patient with our science and our methodologies. I do not ask him to accept what we say, only to allow for the possibility that it may exist, and at some point of evolution our methods may provide him with the proof he so desires."

I responded, "Regarding the purpose of the research we are doing, we are not looking to investigate a purported phenomenon. We are not sure there is one. What we are trying to investigate is a legitimate claim. That claim is that TTPs are able to feel HEFs. Now the water is definitely muddied as to how define these fields. That is not my fault. I am more or less stumbling into a work in progress and am trying to sort things out.

"I still am not sure what type of field, if there is more than one, that you are talking about. You say that you had taken TT classes and used the technique. Did you feel a HEF? Were the TT courses Rogerian based or the 'other' type?

"So please don't think you need to disentangle communication with me. These aren't my terms. I am willing to test any TTP who states they can feel an energy field, be they Rogerian or not. Now I would most prefer to test the best the field has to offer, such as Dr. Kreiger or any of the other Rogerian TTPs.

"It is important to note that testing and research need not be overly complicated. Usually the simpler the better. I see nothing in the test we have devised could be considered inappropriate. TTPs of all stripes claim to feel HEFs. What is so complicated about that? Why wouldn't anyone want this to be tested?

"When you say, 'I think this is the crux of the discourse between Mr. Glickman and the Rogerians. The energy field he is trying to measure is not the one we're saying we feel,' you really loose me. The energy field I am trying to measure is exactly the one the Rogerians are saying they feel! When Rogerians claim to feel 'their' field, that is a testable claim. The ability to measure this exists right now with exactly the test we've devised!

"Speculating about something and having it be true are two different things. I too wish to evolve and learn but speculation is no substitute for evidence and avoiding testing is no substitute for truth."

Biley jumps in here with: "I think a Rogerian would say that they 'perceive' a field manifestation, rather than feel a field, i.e. we chose to call what ever is going on a perception of an energy field rather than say that it is an energy field or is energy."

These were some interesting and exciting developments. It appears that the Rogerians were backing away from TT. The two concepts that originally supported and "proved" each other were now becoming incompatible!

The debate continued. Richard Cowling RN stated, "Last time the test was offered, I said all that I had to say about the matter. [This refers to several e-mail exchanges we had prior to the November 1996 TT test.] I think that the dialogue spawned by this test has done a great deal of good by allowing people to openly describe various vantage points. I do not share Mr. Glickman's philosophy of science, but respect his right, as I hope he does mine, to advocate for a specific worldview.

Mary Jo Borden wrote, "I have been studying Rogerian Science for only five years and thus am somewhat reluctant to enter this discourse... According to Rogers energy field is the fundamental unit of not just human beings, but of all the living and non-living. Energy field is infinite and integral with all other energy field. This is the unifying concept. Pattern is the distinguishing characteristic of an energy field , thus of a person, or of a plant. Since pattern is the distinguishing characteristic it is pattern which Rogerian scientists and scholars attempt to gain understanding of. It is pattern which is energy field manifestation.

"I have long felt uncomfortable with the Krieger TT movement because it is not congruent with Rogerian science as I explore and evolve understanding of it. I have attended Holistic Nurse meetings and observed TT instruction and practice. The TT practitioners do imply ability to feel energy field. I have excused this by allowing that there are many ways to feel a phenomenon. However, the TT practitioners and teachers I have observed do not study or incorporate Rogerian theory into the teaching of TT. If the TT practice emerged from Rogerian science and were congruent with Rogerian science perhaps practitioners would be co-participating with the patient in therapeutic pattern recognition, and per Margaret Newman, repatterning. Perhaps Mr. Glickman is making assumptions about the beliefs of all Rogerians because of the tie between Rogerian science and non-invasive modalities advocated by Rogers. I believe that energy field is not emanating and physically palpable, but rather manifest as pattern . I am an energy field. I don't have one!"

I followed up on these responses with a note to several people at once. "There is one thing that never fails to mystify me. This is the way people try to restate my intentions and/or motivations and how far off these restatements are from what I wrote. I have been writing in the simplest and clearest terms possible precisely to avoid such misunderstandings. One more time, by responding to comments to me, I will state why I am here and what it is I am trying to do.

"First, I want to respond to Margaret Lunney, Ph.D., RN, CS, who stated, 'I am not a therapeutic touch practitioner but I support others in their ability to use TT because of the scientific evidence that it works. Glickman should read the evidence or be open to have therapeutic touch yourself and see what it can do. It sounds, however, as if you are afraid and suspicious of anything you can't see.'

"Contrary to what you may think, I have studied the evidence for TT. >From Krieger's initial hemoglobin study to the present, it is virtually non-existent. TT studies have suffered from poor design, poor methodology, poor controls, improper or absent double-blinding measures and improper statistics to name a few. Don't take my word for it. Therese Meehan RN, Ph.D., a Rogerian TT researcher stated, 'What current research tells us, according to Popper's principles of refutation and verification, is that there is no convincing evidence that TT promotes relaxation and decreases anxiety beyond a placebo response, that the effects of TT on pain are unclear and replication studies are needed before any conclusions can be drawn. Other claims about outcomes are, in fact, speculation.' (Meehan 1995) I could cite more but I don't think it is necessary.

"The healing effects noted by many TT practitioners can too easily be attributed to the Placebo Effect. This is the prime source of static and false positives in healing studies. To make any definitive statement about any healing modality, it MUST be effectively ruled out in any study.

"Regarding the notion that I am 'afraid and suspicious of anything I can't see,' I don't know why you would think that. If I was fearful of TT, the last thing I would do would be to design a test that would conclusively prove a major plank of the TT concept. The only people who have something to fear are the ones that have something to hide. I seek and embrace the truth, not fear it.

"To Mary Jo Borden: Let me clarify what I do understand and what elements of TT and Rogerian theory I am trying to test. I do know about electromagnetic fields. I know that they are proven to exist. I know that a hypothesis regarding the nature of this concept can be formulated and predictions of an outcome can be made. Then the testing of this hypothesis can begin and results of the testing can be analyzed. The best part is that everyone can learn and understand the terms and procedures so they can independently repeat the test on their own. This is the scientific method and how knowledge is obtained. In TT and in Rogerian science, I don't see this process at all. As stated before, the TT scientific research is groundless. In Rogerian science, speculation is mounted on more speculation creating newer and grander ideas, but no actual specific testing is done. If anything, many of these ideas are beyond testing. Without this vital testing, upon which factual and useful data can be built, statements like 'I believe that energy field is not emanating and physically palpable, but rather manifest as pattern' are virtually devoid of meaning.

"Then there is the 'Blur.' The Blur is where TT science and Rogerian science 'overlap.' I am constantly being accused of not understanding the differences in the TT HEF that can be felt and the Rogerian HEF that can be perceived. As mentioned in a previous note, based on what is written in this e-mail service, this confusion is commonplace and constantly debated among the Rogerian scholars themselves. When it is convenient, positive or conclusive, the TT HEF and the Rogerian HEF are the same thing. When it is detrimental, they aren't the same thing. Yet several Rogerians talk about the TT studies they are working on. This confusion isn't mine. It belongs to the people of Rogerian science. It is also their duty to straighten it out.

"So I am not trying to make any assumptions at all. Both the TT people and some of the Rogerians claim, in some way, to be able to feel or perceive a HEF or a human energy manifestation. Until someone can be more definitive, I personally don't care who does what. What I do care about is that when a testable claim, especially one that severely deviates from the known scientific paradigm, is made under the guise of science, it must be properly tested.

"To Richard Cowling: Yes, I respect your right to advocate for a specific world view. What I am trying to do is encourage you and all to refine that view into something that is more scientific and accessible to those outside of Rogerian science."

Cowling responded with the following. "Respectfully, Mr. Glickman, you do not need to encourage me (not sure what others you refer to) in refining my view into something scientific as it is already scientific as has been expressed in volumes of literature and support. I acknowledge your view and you apparently do not acknowledge (and perhaps may not understand) my view. I support your work and your intentions. I do not request your support or encouragement. I do acknowledge, as do many other scholars of science, that there is more than one scientific perspective of merit. I will be attending an interdisciplinary conference in Los Angeles in June sponsored by the University of Southern California, University of California at Los Angeles, and University of California at Irvine. The title of the conference is Reclaiming Voice: Ethnographic Inquiry and Qualitative Research in a Post-Modern Age. I think the introductory description is relevant here:

'At a time when the pressure for change in the academy is increasingly linked to the resurgence of conservative and neo-liberal discourses and practices, researchers need to be more direct in countering the attacks in the public space against alternative methodologies. While the need for research to be theoretically rigorous and ethically accountable is vital, we must be clear that rigor and accountability are not the sole provinces of conservative and neo-liberal educational discourses and practices. Good qualitative research helps establish the importance and validity of human experiences, and improve the human condition. RECLAIMING VOICE...acknowledges differences in inquiry and promotes a verisimilitude of (re)presentations and analyses. The conference is intended for those of us concerned about working with alternative methodological and theoretical frameworks. By joining in rigorous, lively interchanges, participants will better understand how to utilize ethnographic and qualitative research, as well as how to (re)claim and (re)present the voice of ourselves and those with whom we engage in research.'

"I do not care to engage in an attack and defense game with you, Mr. Glickman. This is an old model of discourse. I continue to respect your strength, convictions, knowledge, persistence, and systematic actions in behalf of your singular cause."

This became the last bit of actual dialogue that I was going to receive from the Rogerians. So I ended with this parting shot.

"Richard,

My words here are meant to be a constructive criticism and not an attack or a lack of respect for you and your efforts and the efforts of others (meaning the other people in Rogerian science especially those who contribute to this e-mail service). As a nurse, I am interested in what effects Rogerian science and TT will have on my profession. I have examined the TT research thoroughly. I have only begun looking into Rogerian 'science' but the combined TT/Rogerian research I have reviewed is poor. Again, the people here have a hard time determining which energy field is which and I cannot tell if anyone is concerned by this ongoing confusion.

"Where we differ is in the value and significance of the scientific method (SM). The SM is what science is all about. When scientists do not follow the SM, they are doing something other than science. How else is there to be a standard for everyone to follow so that we are able to check that we doing the same work, techniques and studies? How else are we to eliminate error? How else are we to prevent the wishful thinking of a researcher from becoming part of the result of his work? When bias and error are not eliminated, chaos is the end result.

"Wishful thinking is the engine that drives science, but it can't be the science by itself. There are all kinds of 'sciences' out there that are actually pseudosciences. Many have the rubber-stamp of approval of apparent scientific boards and Universities. TT is also considered by many to be 'scientific' and this has been expressed in volumes of literature and support. It is also featured and promoted by many Universities and Nursing organizations such as the ANA and NLN. This support still doesn't make TT scientific. With TT, the SM has been totally ignored. The 'scientific' literature on TT is baseless. Although accepted by too many in Nursing, no one has yet been able to prove the most basic tenant of TT -- 'Can anyone actually feel a field?' Again that is the purpose of this legitimate scientific test. I still can't imagine why people are offended by this test when they should be pleased by a golden opportunity to demonstrate what many do on a daily basis.

"The history of science is filled with people who have complained about having to deal with the SM. Creation 'science,' cryptozoology, N rays, ESP, cold fusion, psychokinesis are just a few of the many ideas that do not hold up when subjected to the SM. Famed physicist Nikola Tesla is a great example of someone who tried to beat the SM. He started out with some progressive ideas (including the alternating-current motor and the Tesla Coil which is used in Kirlian photography of all things) but came up with some wilder and untenable ones toward the end of his career that didn't pan out. He eventually died in poverty blaming the scientific community for his problems. Today he is the hero of every crackpot who ever dreamed up a perpetual motion or free energy machine. So there is a long precedent set for people who want to circumvent the SM and for obvious reason.

"Not knowing the difference between fantasy and reality is dangerous. People who don't know the difference but should and have a 'scientific' background are among the most dangerous of all. Although many are honest and well meaning, they have the greatest potential to mislead an uninformed public. There are several gurus today who have attracted a large following by mixing mainstream medicine with a multitude of fantasy ideas.

"I do not want to comment about the RECLAIMING VOICE project until I know more about it and what promoting a verisimilitude of representations and analyses entails. What I hope this project isn't, is an opportunity for a group of disgruntled scientists trying to bypass the scientific method to become self-satisfied with their ideas."

Cowling responded with the following line: "Thanks for sharing your thoughts with me."

Although I received some interesting insights into the views of "Rogerian Science," I sure didn't get any volunteers for testing.

Rosa, L.A. (1994) Therapeutic Touch: Skeptics in hand-to-hand combat over latest New Age

Bob Glickman had the following email discussion about Rogerian claims

Unfortunately, I am as baffled as you are regarding Roger's theories and concepts. Before I go into that I want to repeat a great quote I heard from Neil deGrasse Tyson, an astrophysicist from Princeton University. He says, "Before you can say anything about anything, you have to be able measure it." To me, this quote really says alot and on many different levels. There are the basic measures such as height, length, width, weight and time that are easily measured by simple tools. Then there are more advanced measuring tools such as spectrometers and various other tools in physics that do more advanced measuring.

There are also other types of "tools" that can be used for more abstract and subjective ideas. I have had some discussions with pro-TT people that said that things like love and pain can't be scientifically proved but are accepted as real and therefore this leaves the door open to a concept like TT. I don't necessarily agree with this idea. Concepts such as love and pain can be measured in different ways. I do not know if you are a nurse but you may be familiar with the 1-10 pain scale to determine the severity of pain a patient is experiencing. "0" means no pain, "1" means minimal pain, "5" is moderate and "10" is the most pain a person can imagine. This is a rudimentary tool but it allows us to MEASURE something as abstract as pain. (A similar process for love could be developed. I know that I love my wife more than the guy who fixes my car. I know that I love the guy who fixes my car more than the person who would like to steal my car.) With these tools that give us an ability to measure, we can now say something about pain and love.

Rogers' material and ideas give us nothing to measure. When Rogers stated that the HEF was electrodynamic in nature, she gave us something to measure with real scientific tools. Since there is no electomagnetic component to the HEF, backing away from this concept was her only avenue to keep the HEF idea viable. A mystical, forth-dimensional life energy field apparantly has a longer shelf-life than an electromagnetic one. Other ideas as they appear in her "science" such as helicacy, patterning, resonancy, integrality are equally unmeasurable.

In my discussions with Rogerian scholars I found that Rogerian's 'perceive' a field manifestation, whereas the TTers feel a field. I have no evidence that either group can feel or perceive any kind of human energy manifestation. So as to whether the Rogers perspective and the TTers perspective are the same or that they are mutually exclusive, I haven't a clue and neither apparrantly do they. What I do know is that when it is convenient, positive, or conclusive, the TT HEF and the Rogerian HEF are the same thing. When the circumstances are detrimental, they aren't even close. back to main TT page
