What Number Is Halfway Between 1 and 9? Is It 5 — Or 3?
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: 30 is 1, and 32 is 9, so logarithmically, the number halfway between them is 31, or 3. Neural circuits seem to bear out that theory. For instance, psychological experiments suggest that multiplying the intensity of some sensory stimuli causes a linear increase in perceived intensity.

This is a freaking awesome study, by the way.
I guess nobody answered 4.5

whoa cool
People living in small-scale societies = children = HUMAN NATURE fucking idiots.
well technically 4.5 is half of 9, therefore it’s halfway between 0 and 9.
