““our difficulty in accurately recognizing random arrangements of events can lead us to believe things that are not true—to believe something is systematic, ordered, and “real” when it is really random, chaotic, and illusory. Thus, one of the most fundamental tasks that we face in accurately perceiving and understanding our world—that of determining whether there is a phenomenon “out there” that warrants attention and explanation—is a task that we perform imperfectly.””
