Inattentional blindness, also known as perceptual blindness, is when a person fails to notice some stimulus that is in plain sight. This stimulus is usually unexpected but fully visible. This typically happens because we are overloaded with inputs. It is impossible to pay attention to every single input we are presented with. Our attention cannot be focused on everything, and therefore, we all experience inattentional blindness. Sometimes, people falsely believe that they do not experience inattentional blindness. This is due to the fact that they are unaware that they are missing things. Inattentional blindness also has an effect on our perceptions. There have been multiple experiments performed that demonstrate this phenomenon. As a result, there are proposed reasons and ways to prevent this from happening.
