attention blindness

Attention blindness is a psychological phenomenon where focused attention on a specific task or object causes individuals to overlook other relevant information or changes in their environment. This occurs because our brain filters out certain stimuli to avoid overload, but in doing so, it can miss important details outside the current focus. For example, if you're concentrating on finding a specific item, you might completely miss someone approaching or a different object entering your view. It highlights how our focus can unintentionally cause us to ignore critical information, affecting perception and awareness.
