Drivers can look right at a motorcycle and still not register it. Looking and seeing are two different jobs.

Pointing your eyes at something is not the same as taking it in. Your attention runs on what it expects, so a thing that does not match the pattern can sit in plain view and never land. That gap is not stupidity; it is the cost of a mind that filters hard so it can move fast.

The fix is usually a question asked in advance. Before you reread an essay, decide you are hunting for one thing, say every sentence that repeats itself. Before you pull out of a parking lot, look once for what is small and fast rather than for cars.
