To study intelligence we must use quantifiable measures that are correlated with known characteristics of intelligence (problem solving, memory, etc.), amenable to comparisons across a wide range of organisms, and ideally, applicable to fossil as well as living organisms. The Encephalization Quotient (EQ) is one such measure.
