In 1964, the School of the Art Institute of Chicago handed 31 of its students an hour, a sheet of paper, and a long table covered in oddities: grapes, a gearshift, a glass prism, an old book, and 23 other items chosen by two researchers in the next room. Each student could pick whichever objects appealed, set them up however they wanted, and draw. About half got moving fast. They grabbed three or four items, arranged them, blocked in a sketch within minutes, then refined it for the next 55. The other half barely seemed to get started. They picked things up, turned them over, swapped them out, switched paper, erased, restarted. Some were still rearranging at the 50-minute mark and finishing the drawing in a panic. The study named these two patterns: problem-solving (settling on a sketch quickly) and problem-finding (spending most of the hour deciding what to draw). It was run by Mihaly Csikszentmihalyi (who later coined "flow") with Jacob Getzels, and Keith Sawyer recounts it in The MIT Press Reader .…
