A system that incorporates representational authenticity into virtual world interactions can include user representational authenticity data and a virtual world computing system. The user representational authenticity data can be used to describe the physical characteristics of a human user. The physical characteristics can be quantified utilizing standardized measurement techniques. The virtual world computing system can be configured to adjudicate the conduction of interactions performed by a virtual representation of the human user within the virtual world environment utilizing the user representational authenticity data.
