W. Paul Williamson is professor of psychology at Henderson State University (USA), although he has not always been in academic research. He was previously a full-time clergy in a Pentecostal denomination for 17 years, but then became more interested in religion from a psychological perspective. This led to his studies at the University of Tennessee, Knoxville, where he earned a Ph.D. in experimental psychology with training in both quantitative and qualitative research methodologies. Applying these approaches to the psychology of religion, he has published work in the areas of mysticism, religious fundamentalism, Christian serpent handling, and, most recently, spiritual transformation within the context of substance abuse recovery. He has co-authored The Psychology of Religious Fundamentalism (2005, Guilford Press), with Ralph W. Hood, Jr., and Peter C. Hill; and Them That Believe: The Power and Meaning of the Christian Serpent Handling Tradition (2008; University of California Press), with Ralph W. Hood, Jr. He is a recipient of the Margaret Gorman Early Career Award and the Distinguished Service Award, both from the American Psychological Association, Division 36: Society for the Psychology of Religion and Spirituality.
According to Williamson, “What so often is missing in research is a balanced approach in the psychological study of religious phenomena. It typically is either from the objective standpoint or from the subjective point of view. What is needed for a more complete understanding of a particular phenomenon is the blending together of both perspectives in the use of quantitative and qualitative methodologies.”
