This article is based on ICAR’s Contactee Blood Types, which has been published on their site for a few years. After looking carefully at their questionnaire as well as the findings of Kathleen Marden and Denise Stoner from their Commonalities Report, this project evolved into a five part exploration if you will. What we are attempting to offer here is an overview of ICAR’s and the Marden-Stoner research results, as well as suggestions on ways to improve the ICAR questionnaire and therefore improve the accuracy of the reporting on commonalities such as ET Contact cases and blood types.

When it comes to reporting on ET Contact cases, various terms are often thrown around in ufological circles because simply put, it’s easier to criticize or debunk than to do the hard work of legitimately searching for answers. Because the scientific community refuses to accept, much less seriously study, ET Contact, we are left with very few resources and the “scientific” expertise we so desperately need. We have had to pool our personal knowledge in order to report, as accurately as we can, what we believe is happening and why ET Contact is occurring to certain individuals. Because the beings themselves operate in near or total secrecy, it makes finding the answers all the more difficult.

A biological focus, familial for example, has been determined to be related to the selection process of humans by at least some extraterrestrials. Reasonable areas of study would be human DNA and genetics (very expensive subjects to study) as well as blood types (not so expensive to study). In general, the physiological attributes of the people experiencing contact are an obvious place to look for answers. Others might disagree and say it’s all paranormal or based on a soul contract with the Visitors, and that might be the case; however, those areas of study are even more elusive.

The ABO Blood Group System

Among other attributes, ICAR and Kathleen Marden and Denise Stoner looked at blood types, including the Rh factor, of people reporting ET Contact. The ABO blood group system we rely on today was co-discovered by microbiologist and serologist Ludwik Hirszfeld and biologist and physician Karl Landsteiner.  Landsteiner also co-discovered the Rh factor and its negative effects on mother and fetus. If a mother is Rh-negative and the father is Rh positive, the fetus can inherit the Rh factor from the father thus making the fetus Rh positive. Problems can arise when the fetus’s blood has the Rh factor and the mother’s blood does not.

Nearly everyone at one time or another has either speculated about or studied the origins of blood groups. Some people claim there is an ethnicity factor to blood groups while others dispute this claim. We know very little with 100% accuracy except, generally speaking, blood type O is most prevalent in Africa and the Americas; blood type A is most prevalent in Europe, and blood type B is most prevalent in Asia.

In Blood Purity: How a Bizarre Obsession Advanced Science, it is written that “Today’s researchers see the key to understanding blood groups in the particular characteristics possessed by each group. People with type O blood, for example, possess greater immunity to malaria. Scientists thus believe that this blood group developed in Africa millions of years ago as an evolutionary response resulting from a mutation of type A blood.” On the other hand, due to geographical and environmental changes over time, can we really know that malaria was as bad in Africa millions of years ago as it is today?

The author further writes, “Type B blood, meanwhile, possesses a higher degree of immunity to the plague and may have developed in areas where that illness was especially devastating.” And, although the Japanese, who take blood types into consideration when choosing a mate, would certainly disagree, the article goes on to state, “Blood groups, however, have nothing at all to do with personality traits.”

Marden-Stoner Commonalities Report

Abduction researchers Kathleen Marden and Denise Stoner have been aware for quite some time of repeating patterns and characteristics related to people experiencing ET contact. Marden writes in the introduction of their Commonalities report:

“The pertinent literature, the academic social science studies and the works of David Jacobs, Ph.D., Thomas Bullard, Ph.D., Yvonne Smith, C.Ht. the late Budd Hopkins, John Mack, M.D., and others had identified several commonalities among abduction experiencers. But we had not been able to locate an academic study that was specific to our particular interests.” Because of this, Marden and Stoner decided to develop two questionnaires that might help them determine what specific commonalities were present, which then led to a third questionnaire. Marden explains,

“The ‘UFO Abduction Experiencer Questionnaire’ listed 45 multiple choice questions pertaining to experiencers’ demographics, abduction memories, emotional responses, physiological responses, and psychic phenomena. The second questionnaire, the ‘Abduction Experiencer E.T. Technology Questionnaire’ would increase our knowledge of E.T. technology. The third, ‘Commonalities among Non-Abductees Questionnaire,’ queried individuals who denied having been abducted by aliens. It was developed after the first two questionnaires had been available for several months and a commonalities trend had emerged. The 16 multiple choice questions would determine whether or not some of the commonalities among abduction experiencers are common across the general population.”

According to Kathleen Marden and Denise Stoner’s 2012 Commonalities Report, when questioned about their blood type, of the 29 abductee-experiencers who responded to the question, “59% stated their blood type is type A while 34% stated their blood type is type O.”

“…Because 66% of the respondents reside in the Eastern Time Zone, we researched the distribution of blood types throughout the US. It is estimated that 20-25% of the US population residing in the Northeast and East-Central has type A blood and 70-80% are type O.”

“Does this indicate that there is an elevated percentage of A blood types among abduction experiencers? We compared our statistics to the NAE [Non Abductee-Experiencer] Group and found that 50% are type A and 33% type O. This indicates that the majority of participants in both groups are type A regardless of whether or not they have experienced alien abduction” according to Marden and Stoner.

The Rh Factor: Could it be Significant?

Kathleen Marden and Denise Stoner then evaluated the Rh factor “…knowing that 85% of all humans have Rh+ blood types. We found an elevated percentage of Rh- Factor (35%) among abduction experiencers. The Stanford School of Medicine Blood Center reports that 6.3% of their collected blood types are A negative and 6.6% are O negative. This elevated percentage among abduction experiencers could be significant. Among the NAE [non abductee-experiencer] Group, 83% had a positive Rh factor and 17% were negative indicating that both groups had elevated Rh negative blood types. It is interesting that a significantly higher percentage (18%) of the AE Group reported a negative RH factor than in the NAE Group. However, many participants did not know their blood type, so the sample size is too small to be considered statistically reliable.”

Kathy Marden & Denise Stoner


Kathleen Marden is known around the world for her work as a UFO abduction/ET contact researcher, experiencer rights advocate, author and lecturer. She has 24 years experience in the field. For the past 3 years, she has served as MUFON’s Director of Abduction Research. In 2012, The Mutual UFO Network named her “Ufologist of the Year.” She is also a member of the Foundation for Research of Extraterrestrial Encounter’s Advisory Board and a consultant to FREE’s Research Subcommittee.

Denise Stoner has been active in the UFO field for over 20 years. She is the Director of the Florida Research Group, an affiliation of UFORCOP. She is a member of MUFON’s National Abduction Research Team and is also a Florida MUFON Field Investigator and Star Team Member. Prior to her current positions, she was a Florida MUFON State Section Director and Chief Investigator. Denise holds educational forums for public and private gatherings for abduction experiencers.

Denise Stoner has an educational background in business and psychology, and is a certified hypnotist specializing in regressive hypnosis. She has taught classes in stress reduction for 12+ years for professionals in such fields as medicine and law.

Kathleen Marden earned a B.A. degree in social work from the University of New Hampshire in 1971, and participated in graduate studies in education while working as a teacher and education services coordinator. She also has extensive training in hypnosis.

Her interest in UFOs dates back to September 20, 1961, when her aunt, Betty Hill phoned her nearby home to report that she and Barney had encountered a flying saucer in New Hampshire’s White Mountains. A primary witness to the evidence of the UFO encounter and the aftermath, Kathleen has intimate knowledge of the Hill’s biographical histories, personalities, and the previously unpublished historical files pertaining to their sensational story.

Denise Stoner began her research in hypnosis under Dr. Bob Romack, in Denver, Colorado. They worked together for five years on pain control, smoking cessation, and past life regression research. Denise also worked as a paranormal investigator in the homes of abductees who felt they had been visited by spirits following abductions. She recorded evidence of the development of psychic abilities in individuals following their experiences with UFOs and ETs, and worked on a Team with Dr. Romack studying abductees’ abilities to locate missing people and predict future events.

For 12 years Denise Stoner conducted background investigations for the military on recruits seeking highly classified clearances for work on nuclear submarines. Prior to retirement, Denise moved to the Naval Air Warfare Center, Training Systems Division military research facility where she was the training coordinator for several hundred military and civilian employees.

Her retirement from the Federal Government has allowed her to expand her work with UFO research and investigation. Denise has appeared on TV and has participated in many radio shows. She presents yearly at the Daytona Museum of Arts and Science and the Paranormal Investigative Association, as well as other venues. She has worked as an on-camera expert for documentaries produced in the UK and is currently moving forward with several exciting new projects.
