Changes in Openness after psilocybin in participants who did and did not have mystical experiences. Figure shows Openness T scores at screening (Pre) and post-test (Post) in participants who had a complete mystical experience (n = 30; filled symbols) and those who had an incomplete or no mystical experience (n = 22; open symbols). Data points are means; bars show ± 1 SEM; asterisk indicates a significant difference (p < .001) at the post-psilocybin assessment. Screening levels of Openness and its facets did not differ between participants who met the criteria for having had a complete mystical experience and those who did not (ps > .10).
