Media naturalness theory

Media naturalness theory was developed by Ned Kock. This theory is sometimes referred to as the psychobiological model. It has been used to understand human behavior toward technology in various contexts, such as: education, knowledge transfer, communication in virtual environments, e-negotiation, business process improvement, trust and leadership in virtual teamwork, online learning, maintenance of distributed relationships, performance in experimental tasks using various media, and modular production. Media naturalness theory can be considered a Darwinian theory of behavior toward certain types of communication media. Its development is also consistent with ideas from the field of evolutionary psychology.

The theory builds on human evolution ideas and has been proposed as an alternative to media richness theory. Media naturalness theory argues that since our Stone Age hominid ancestors have communicated primarily face-to-face, evolutionary pressures have led to the development of a brain that is consequently designed for that form of communication. Other forms of communication are too recent and unlikely to have posed evolutionary pressures that could have shaped our brain in their direction. Using communication media that suppress key elements found in face-to-face communication, as many electronic communication media do, thus ends up posing cognitive obstacles to communication. This is particularly the case in the context of complex tasks (e.g., business process redesign, new product development, online learning), because such tasks seem to require more intense communication over extended periods of time than simple tasks.

A simple thought experiment highlights the biological basis of media naturalness theory, and the fundamental difference between the media naturalness and media richness theories. Let us assume that the human species had evolved in an ancestral environment without light. If that were the case, modern humans would all be blind, and therefore a communication medium's ability to convey facial expressions and body language would be irrelevant for effective communication. Conversely, a medium's ability to convey smell might be fairly important for effective communication. This illustrates the fact that one cannot define a medium's ability to support effective communication without taking into consideration characteristics of the communicators. Of these, biological characteristics often have an evolutionary basis.
