“We chose to focus on creative problem solving for several reasons. One was its obvious utility, an important consideration at that juncture because of those who doubted that psychedelics were good for anything at all. Besides, many of the spontaneous occurrences we had observed were of this problem-solving kind. Finally, extensive research activity in the field of creativity had yielded a number of objective measures to use. The study attempted to shed light on three questions: Can the psychedelic experience enhance creative problem-solving ability, and if so, what is the concrete evidence of enhancement? Can this enhancement lead to concrete, valid, and feasible solutions assessable by the pragmatic criteria of modern industry and mainstream science? In working with creative individuals, would there be changes indicative of increased creativity continuing after the psychedelic intervention?”
