Overview
Insight is the understanding of a specific cause and effect within a particular context. The term insight can have several related meanings:
a piece of information
the act or result of understanding the inner nature of things or of seeing intuitively (called in Greek)
an introspection
the power of acute observation and deduction, discernment, and perception, called intellection or
an understanding of cause and effect based on the identification of relationships and behaviors within a model, system, context, or scenario (see artificial intelligence)
An insight that manifests itself suddenly, such as understanding how to solve a difficult problem, is sometimes called by the German word . The term was coined by the German psychologist and theoretical linguist Karl Bühler. It is also known as an epiphany, eureka moment, or (for crossword solvers) the penny dropping moment (PDM). Sudden sickening realisations often identify a problem rather than solving it, so Uh-oh rather than Aha moments are seen in negative insight. A further example of negative insight is chagrin which is annoyance at the obviousness of a solution that was missed up until the (perhaps too late) point of insight, an example of this being Homer Simpson's catchphrase exclamation, D'oh!.
Psychology
In psychology, insight occurs when a solution to a problem presents itself quickly and without warning. It is the sudden discovery of the correct solution following incorrect attempts based on trial and error. Solutions via insight have been proven to be more accurate than non-insight solutions.
