Colin A. Chapman and Michael A. Huffman, Why do we want to think humans are different?


Chapman & Huffman review and evaluate various aspects of the notion of human superiority. In this commentary we focus on intelligence and suggest a biologically based view of intelligence applicable to humans and non-human species alike. “Mental manipulation” (e.g., mental transformations, rotations, perspective-taking), an extension of object manipulation, provides a continuous, biologically based concept for studying intelligent behavior in humans and other species and challenges the notion of human superiority.
