What is one possible reason that we are susceptible to change blindness?

There are other factors that could influence change blindness, including attention, age, how objects are presented, and the use of psychoactive drugs. Researchers have also found that shifting a person’s attention, such as by causing a distraction, leads to increased change blindness.

What is the difference between change blindness and inattentional blindness?
