"Ask adults from the industrialized world what number is halfway between 1 and 9, and most will say 5. But pose the same question to small children, or people living in some traditional societies, and they're likely to answer 3. Cognitive scientists theorize that that's because it's actually more natural for humans to think logarithmically than linearly." Fascinating. The human brain is such a magical machine.

Huh! Huh! Huh1
You are so wrong. The question is half way between 1 and 9 not (0 and 9). The difference between 1 and 9 happens to be 8 and half of 8 happens to be 4. Therefore there is only one correct answer (4). If the question was halfway between 0 and 9 the exact answer will be 4.5 and rounding up to the nearest unit it will be 5.

If I follow you, halfway of 7 and 9 is (9-7)/2 = 1.

The mean of a and b is (a+b)/2
