Now, look down at this page. Blocking off your peripheral vision, think of everything that’s… green. If you’re in a room you know very well, you can probably do this easily, but if you’re in a strange room, chances are that you’ll remember a lot more brown than green. So now look around and notice what’s green: green, green, green. Do you see more green this time? Again, if you’re in an unfamiliar environment, I’m sure your answer is yes. What does this teach us? Whatever we look for we’ll find.
