We went to the airport the other day and realized that we were out of cash. I stopped at an ATM, pulled out a credit card, and froze. I rarely use that particular card at ATMs and I had completely forgotten the personal identification number. I stared blankly at the ATM screen for a few minutes and then slowly started to walk away.
A few seconds later, the number popped into my head: 2061. I’m used to having things pop into my head as I “give up” on a problem. When I focus on a problem, I block out information. As I start to unfocus, useful information pops back into my head. I find that I’m much less creative when I’m intently focused. (Recently, for instance, Steven Wright popped into my head.)
Pleased that my mind was working so effectively, I returned to the ATM, inserted my card and the digits 2061. Wrong. Hmmm … perhaps I transposed some digits. I tried various combinations: 2601, 2106, 1206, and so on. Nothing worked.
So again, I walked slowly away from the terminal. As I did, I noticed that I was standing next to an airport conference room. The number on the door: 2061. My System 1 had picked up the number subconsciously. It wasn’t a useful data point so System 1 didn’t register it with System 2. Then my System 2 broadcast a message: “We’re looking for a four digit number.” At that point, System 1 produced the most recent four-digit number it was aware of: 2061.
Unfortunately, it was the wrong number. But I was convinced it was the right number. It popped into my head just the way I expected it to.
Was my mind playing tricks on me? Not really. In David Brooks’ phrase, my “millions of little scouts” were out surveying my environment. One scout sent back some information that might be useful, the number 2061. The little scout was trying to help. Unfortunately, he led me astray. System 1 is usually right. But when it’s wrong, it can get you into big trouble. Like getting your credit card cancelled
