attention

You are blind to obvious changes in your environment.

Inattentional blindness occurs when you fail to perceive an unexpected stimulus due to focused attention on another task.

In a famous experiment, researchers found that nearly half of the participants focused on a basketball game failed to notice a person in a gorilla suit walking across the screen. Your brain is not a camera recording everything; it is a filter prioritizing specific inputs. You do not see what you are not looking for.

Your focus is also a limitation.
