Think of intuition as an unconscious associative process. Long dismissed as magical or beneath the dignity of science, intuition turns out to muster some fancy and fast mental operations. The best explanation psychologists now offer is that intuition is a mental matching game. The brain takes in a situation, does a very quick search of its files, and then finds its best analogue among the stored sprawl of memories and knowledge. Based on that analogy, you ascribe meaning to the situation in front of you.
