Simplicity has lengthy been seen as a virtue of scientific explanations, but it’s notoriously tough to determine what makes one rationalization less complicated than one other. However, the dictum relating to the need to avoid anthropomorphism can also be a philosophical assumption embedded in comparative cognition and, as such, it might be questioned. It has been argued, as an example, that a blanket ban towards the attribution of human-like qualities to animals would beg the question by assuming that said qualities are certainly uniquely human . Frans de Waal makes use of the time period “anthropodenial” to refer to the a priori rejection of the likelihood that people and animals may share characteristics, and argues that it is just as worrisome as anthropomorphism.

For instance, when scientists embark on an experimental project to discover out whether or not a certain species has capacities corresponding to altruism, cooperation, or empathy, they assume a sure definition of these terms.
