Because your brain uses information from the areas around the blind spot to make a reasonable guess about what the blind spot would see if only it weren't blind, and then your brain fills in the scene with this information. That's right, it invents things, creates things, makes stuff up! It doesn't consult you about this, doesn't seek your approval. It just makes its best guess about the nature of the missing information and proceeds to fill in the scene.
Interpretation
The brain compensates for gaps in perception by filling in missing information with assumptions.
Daniel Gilbert's quote highlights the brain's remarkable ability to infer and create a narrative about unperceived information, specifically within the context of blind spots in vision. It underscores how our minds instinctively fill in the blanks based on surrounding cues, often without our conscious awareness or approval, thus illustrating the creative nature of human perception and cognition.
In practice

Part of us believes the new car is better because it lasts longer. But, in fact, that's the worst thing about the new car. It will stay around to disappoint you, whereas a trip to Europe is over. It evaporates. It has the good sense to go away, and you are left with nothing but a wonderful memory.
Psychologists call this habituation, economists call it declining marginal utility, and the rest of us call it marriage.
The mistakes we make when we try to imagine our personal futures are also lawful, regular, and systematic. They, too, have a pattern that tells us about the powers and limits of foresight in much the same way that optical illusions tell us about the powers and limits of eyesight.
When we have an experience -- hearing a particular sonata, making love with a particular person, watching the sun set from a particular window of a particular room -- on successive occasions, we quickly begin to adapt to it, and the experience yields less pleasure each time. Psychologists call this habituation, economists call it declining marginal utility, and the rest of us call it marriage
Alas, we think of ourselves as unique entities-minds unlike any others-and thus we often reject the lessons that the emotional experience of others has to teach us.
What’s so curious about human beings is that we can look deeply into the future, foresee disaster, and still do nothing in the present to stop it. The majority of people on this planet, they’re overwhelmed with concerns about their immediate well being.
How do you know that you are not part of a book? That someone's not reading your story right now?
There are worries that seem to me sustained by the love of worry. For example, that people are reading from screens, or listening to recorded books. Why scold the impulse to enjoy language and narrative in whatever form it takes?
Whatever satisfies the soul is truth.
The world has been created for everyone's use, but you few rich are trying to keep it up for yourselves. For not merely the possession of the earth, but the very sky, the air, and the sea are claimed for the use of the rich few... The earth belongs to all, not just to the rich.
In a certain sense all men are historians.
If I survive, I will spend my whole life at the oven door seeing that no one is denied bread and, so as to give a lesson of charity, especially those who did not bring flour.
