The gorilla in the picture
Today, I'm following up on the video where you were to count how many passes the white team made. Did you notice the gorilla? If you didn't - and about half of people don't - you demonstrate our limited attention budget. People can focus on only one thing at a time.
I came across this example - and many other fascinating examples of "systematic errors in the thinking of normal people...traced...to the design of the machinery of cognition" in Thinking Fast and Slow, a book that explains that humans use two discrete systems that drive the way we think and the way we make choices. We mostly rely on System 1, a kind of automatic pilot that is fast, intuitive, and emotional", but we can choose to engage System 2, a slower, more deliberative, and more logical mode.
When you were counting the passes in the video, you were using System 2. Quoting from page 23:
- The often-used phrase 'pay attention' is apt: you dispose of a limited budget of attention that you can allocate to activities, and if you try to go beyhond your budget, you will fail. It is the mark of effortful activities that they interfere with each other, which is why it is difficult or impossible to conduct several at once. You could not compute the product of 17 X 24 while making a left turn into dense traffic, and you certainly should not try. You can do several things at once, but only if they are easy and undemanding. You are probably safe carrying on a conversation with a passenger while driving on an empty highway, and many parents have discovered, perhaps with some guilt, that they can read a story to a child while thinking of something else.
