Etzel Cardeña is the Thorsen Professor of Psychology (including parapsychology and hypnosis) at Lund University, Sweden where he is Director of the Centre for Research on Consciousness and Anomalous Psychology (CERCAP). A native of Mexico, Cardeña studied at the Universidad Iberoamericana in México and completed an MA in clinical psychology at York University in Toronto, Canada and an MA and PhD in Personality Psychology at the University of California, Davis. His doctoral thesis under the supervision of Charles Tart was on the phenomenology of deep states of hypnosis. He subsequently went on to do post-doctoral work in the area of dissociation and hypnosis at Stanford University under David Spiegel.^[11] Cardeña has held academic posts at Georgetown University, the Uniformed Services University of the Health Sciences (USUHS) and the University of Texas–Pan American, among others. He has served as President of the Society of Psychological Hypnosis (APA Division 30) for 2000–2001,^[3] the Society for Clinical and Experimental Hypnosis for 2001–2003,^[4] and the Parapsychological Association for the year 2008-2009. He has expressed views in favour of the validity of some paranormal phenomena. In a recent paper in American Psychologist he wrote that "The evidence for psi is comparable to that for established phenomena in psychology and other disciplines, although there is no consensual understanding of them."^[12]

In a series of interviews with Swedish Newspapers he has said that there is evidence for telepathy, psychokinesis and precognition and that he himself has had experiences that could be interpreted as supporting the psi hypothesis.^[13] The Parapsychological Association honored Cardeña with the 2013 Charles Honorton Integrative Contributions Award.^[8] Cardeña has written more than 300 publications. His edited book Varieties of Anomalous Experience: Examining the Scientific Evidence published in 2000 and a second edition in 2014 is a scholarly volume on anomalous experiences.^[10] His two volumes Altering Consciousness discusses the importance of altered states across history, culture, and in many disciplines including philosophy, anthropology, psychology, biology, and various others.^[9]

In addition to his professional work in psychology Etzel Cardeña is the Artistic Director of the International Theatre of Malmö and has worked in theatre as a director, actor and playwright in Mexico, the USA and Sweden. He did graduate studies in theatre directing at the University of California, Davis, after having worked professionally in theatre in México^[14] and been offered scholarships from the Polish and Canadian governments to do graduate work in acting.
