Repugnancy costs are costs borne by an individual or entity as a result of a stimulus that goes against that individual or entity's cultural mores. The cost could be emotional, physical, mental or figurative. The stimulus could be anything from food to people to an idea.
These costs are perspective-dependent and individual. These costs may be different for different groups of people; countries, states, ethnicities, etc. The term allows for a clear and understandable way of representing the concept of contextual stigma in a literal and applicable sense.
