Some say that animals are less intelligent only according to anthropocentric definitions. I would like to clarify, that even by anthropocentric definitions, we still may not be the most intelligent. This post discusses this topic in depth, criticizing this assumption that I believe stems from dogma, similar to the assumption that Earth is the center of the universe. We may have the strongest sociological intelligence of all animals, but individually, we are not very intelligent, where chimps are superior, due to pharmacological/physiological reasons, physiological reasons that directly relate to the precise factor that allows for strong sociological development: domestication.
