Restructuring insight: An integrative review of insight in problem-solving, meditation, psychotherapy, delusions and psychedelics

Insight, the sudden understanding of a solution or idea, is not only central to creative problem-solving but also plays a key role in psychotherapy, meditation, the emergence of delusions in schizophrenia, and the therapeutic effects of psychedelics. This integrative review draws on literature from multiple fields to examine the event of insight, its prerequisites, and its consequences. It highlights commonalities and differences across these domains, aiming to bridge gaps between disparate research traditions and inspire interdisciplinary efforts to understand this core cognitive process.

Abstract

Occasionally, a solution or idea arrives as a sudden understanding - an insight. Insight has been considered an “extra” ingredient of creative thinking and problem-solving. Here we propose that insight is central in seemingly distinct areas of research. Drawing on literature from a variety of fields, we show that besides being commonly studied in problem-solving literature, insight is also a core component in psychotherapy and meditation, a key process underlying the emergence of delusions in schizophrenia, and a factor in the therapeutic effects of psychedelics. In each case, we discuss the event of insight and its prerequisites and consequences. We review evidence for the commonalities and differences between the fields and discuss their relevance for capturing the essence of the insight phenomenon. The goal of this integrative review is to bridge the gap between the different views and inspire interdisciplinary research efforts for understanding this central process of human cognition.
