Intuitions are sudden, strong judgments whose origin cannot be immediately explained.
They seem to emerge from an obscure inner force, but they actually begin with a fleeting perception that starts a mental process.
Science attempts to explain intuition as a kind of “mental matching game,” in which the brain absorbs a given situation then instantaneously rifles through mental files to find the most accurate connections, based on knowledge and memories.
A well-developed intuition is a great first step toward solving problems or deciding how to proceed. To that end, anyone can improve their general interpersonal intuition if they’re motivated to take a greater interest in understanding people and garnering a broad range of experiences.
