The second person didn’t try to develop a plan for solving the puzzle because, “you don’t know until you get there.” She simply leans into her own special skill.
She has a highly developed sense of pattern recognition. So for her, unusual combinations of shape and color are quickly noticed and easily remembered. She picks up a random piece, then picks up a piece that will connect to it. Each time she scans the field of 1,000 pieces, she deepens her subconscious memory of exactly what is lying where. To observers, she appears to have a magical gift because her ability to locate the piece she needs accelerates minute by minute. She prefers to use the right hemisphere of her brain, which exists primarily for identifying patterns. The non-sequential logic of the right hemisphere is called intuition because the patterns identified and catalogued are not just patterns of shape and color, but patterns of behavior, relationships, history, sequences of musical notes, and a variety of other things. Most of the things we call “talent” are merely expressions of unconscious pattern recognition.
I chose the pronoun “she” for this second person, but it could just as easily have been a “he.”
