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.

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.
To interpose the threat of physical destruction between a man and his perception of reality, is to negate and paralyze his means of survival to force him to act against his own judgment, is like forcing him to act against his own sight
Imagine me; I shall not exist if you do not imagine me; try to discern the doe in me, trembling in the forest of my own iniquity; let's even smile a little. After all, there is no harm in smiling.
I feel shame, not for the wrong things I have done, but for the right things that I have failed to do.
Nobody is qualified to become a statesman who is entirely ignorant of the problem of wheat.
I pray every night, sometimes long prayers about a lot of things and a lot of people, but I don't talk about it or brag about it because that's between God and me, and I'm no better than anybody else in God's sight.
No Santa Claus! Thank God! he lives, and he lives forever. A thousand years from now, Virginia, nay, ten times ten thousand years from now, he will continue to make glad the heart of childhood.
