Restructuring insight: An integrative review of insight in problem-solving, meditation, psychotherapy, delusions and psychedelics
Occasionally a solution arrives as a sudden understanding - an insight. Insight has been considered as an “extra” ingredient of creative thinking and problem-solving. Here we propose that insight is a central process in seemingly distinct areas of research. Drawing on literature from a variety of fields, we show that besides being a common topic in problem-solving literature, insight is also a core component in psychotherapy, essential for some forms of meditation, a key process underlying the emergence of primary delusions in schizophrenia, and a factor that drives the positive outcomes of psychedelic therapy. Our goal is to bridge these different views and research traditions. In each case, we discuss the prerequisites and consequences of insight. We examine evidence for common prerequisites of insight experiences, comprising a tension within knowledge structures and a plastic state of mind. We discuss a framework for explaining insight across these fields and highlight the clinical relevance of studying insight. This integrative review provides a better understanding of insight, a central feature of our minds.
