In the News "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?

I would have thought it was 1 plus 9 divided by 2.

A person who had no simple math skills may have decided to try 3 as a guess.

Correct formula is geometric mean: Sqrt(1*9) = 3

I wonder what would be their answer if the question was the middle of 1 and 16 ???
