ABSTRACT
“Quantum change” has been conceptualized as sudden and significant life-altering transformation. It is sometimes referred to as an epiphany because those who experience quantum changes frequently report profound realizations of self and life. Quantum change experiences are often reported as life-altering and may involve characteristics associated with the subjectivity of mystical experiences (i.e., noetic qualities, ineffability, transiency, passivity, unity, transcendence, awe, positivity, and distinctiveness). The construct of quantum change may be important to the field of social science, including psychology and the present volume, because this phenomenon has been reported throughout the human history, but it has received relatively little research attention since the term “quantum change” was coined in 1991. This chapter summarizes research on quantum change and considers related topics, such as conversion, peak experience, near-death experience, post-traumatic growth, psychedelic experience, and states of awe. The chapter offers some future directions, as further research is needed to understand the way some people experience sudden, “discontinuous” change like quantum change, because of its potential to affect theory, research, and practice in the social sciences. Future research should utilize longitudinal and experimental designs, identify individual and contextual precursors of quantum change, and explore negative aspects of quantum change.
