Step-by-step explanation:
The term insight refers to the ability to understand the true nature of one's problem or situation. It is a cognitive process that involves drawing on prior experiences and reasoning to gain a deep understanding of a concept or predicament, which can lead to insight learning. This kind of learning is characterized by a sudden realization or an 'aha' moment where the solution becomes clear. It is a hallmark of higher intelligence and is particularly significant among humans, who have utilized this faculty to make advancements from inventing simple tools to exploring space.
Critical thinking plays a crucial role in achieving insight, as it involves the ability to identify and solve problems by analyzing and evaluating evidence before forming a judgment. This process is distinct from relying solely on emotions or intuitions, especially in individuals who are not experts in the field. Effective insight also requires a person to be skeptical of automatic responses and to consider various possibilities before reaching a conclusion, akin to a doctor who thoughtfully considers multiple diagnoses before treating a patient.
