A number of studies by [[Roland R. Griffiths]] and other researchers have concluded that high doses of [[psilocybin]] and other classic psychedelics trigger [[mystical experience]]s in most research participants.{{sfn|Griffiths|Richards|McCann|Jesse|2006}}{{sfn|Barrett|Johnson|Griffiths|2015}}{{sfn|Barsuglia|Davis|Palmer|Lancelotta|2018}}{{sfn|Johnson|Hendricks|Barrett|Griffiths|2019}} Mystical experiences have been measured by a number of [[psychometric]] scales, including the [[Ralph W. Hood|Hood]] Mysticism Scale, the Spiritual Transcendence Scale, and the Mystical Experience Questionnaire.{{sfn|Johnson|Hendricks|Barrett|Griffiths|2019}} The revised version of the Mystical Experience Questionnaire, for example, asks participants about four dimensions of their experience, namely the "mystical" quality, positive mood such as the experience of amazement, the loss of the usual sense of time and space, and the sense that the experience cannot be adequately conveyed through words.{{sfn|Johnson|Hendricks|Barrett|Griffiths|2019}} The questions on the "mystical" quality in turn probe multiple aspects: the sense of "pure" being, the sense of unity with one's surroundings, the sense that what one experienced was real, and the sense of sacredness.{{sfn|Johnson|Hendricks|Barrett|Griffiths|2019}} Some researchers have questioned the interpretation of the results from these studies and whether the framework and terminology of mysticism are appropriate in a scientific context, while other researchers have responded to those criticisms and argued that descriptions of mystical experiences are compatible with a scientific worldview.{{sfn|Sanders|Zijlmans|2021}}{{sfn|Breeksema|van Elk|2021}}{{sfn|Jylkkä|2021}}
