The Anthropocentric Bias in Animal Cognition

Abstract

In the classical philosophical tradition, animals had the special function of serving as “objects of comparison” concerning humans. In that sense, philosophy adopted a peculiar comparative perspective focused on the categoric difference that separates humans from other creatures: an exceptionalist perspective. The Humanities developed an anthropocentric canon for the study of animals and privileged the search for differences over similarities of these with humans. On the other hand, the great boost that animal studies received under the influence of Darwin's work promoted a different comparative perspective in the natural sciences. However, especially in comparative psychology, ingent efforts were devoted to avoid the errors that anthropomorphism would entail: attributing human properties to other creatures and privileging similarities over differences. It assumed that anthropomorphic bias entails a more fundamental type of error than anthropocentric bias. Now, this asymmetric diagnosis has beenunmasked with different arguments. In the context of both disciplinary traditions, it is timely to reexamine the most persistent and negative manifestations of anthropocentric bias as a comparative bias for the study of animal cognition. In this work I will identify the following: the homogenization of animals into a single general category; psychological speciesism and the “de-mentalization” of animals; the survival of a hierarchical conception of cognitive abilities; the selective application - only to animals - of Morgan's Canon or anthropodenial and its complement, the assumption of idealized mental capacities in the human case or anthropofabulation; asymmetrical or distorsive methodological strategies for the study of animals versus humans which affects the comparative interpretations; and different manifestations of semantic anthropocentrism.
