How Number Illusions Fool Your Brain

The number 8249 contains the same digits as 8429 but arranges them differently. Since the digits look familiar, your brain tends to miss the difference. Your eyes might scan across the numbers but your mind assumes it knows what is there & tells you that nothing has changed. This problem gets worse when you have limited time. When you feel rushed, your brain depends more on quick assumptions rather than careful examination.
