Cranial capacity

From Citizendium, the Citizens' Compendium

Cranial capacity is the cubic capacity of the braincase estimated for the living by a formula based on head measurements. It is determined by filling the cranial cavity with some kind of material such as mustard seed or glass beads and then measuring the volume.^[1] Cranial capacity has little correlation to intelligence. In a study done by Sir Francis Galton at the University of Cambridge, it was determined that there was no measurable difference in cranial capacity vs. college test scores.^[2]
