"It is easy to talk about great ideas as if they were light-bulb moments, sudden epiphanies where everything comes together at once. But Steven Johnson, author of 'Where Good Ideas Come From,' says that's rarely how it works." "Johnson also suggests that good ideas don't come from a lone genius working in a lab as often as they come from interactions between geniuses. Just think of what the coffeehouse did for the Age of Enlightenment." Quiet ideas that linger in the background and take time to evolve are what Johnson calls the 'slow hunch'.
