Shared reality: Construct and mechanisms.

To provide background for the Special Issue on shared reality, we outline the construct of shared reality and underlying mechanisms. Shared reality is the experience of having in common with others inner states about the world. Inner states include the perceived relevance of something, as well as feelings, beliefs, or evaluations of something. The experience of having such inner states in common with others fosters the perceived truth of those inner states. Humans are profoundly motivated to create shared realities with others, and in so doing they fulfill their needs to have valid beliefs about the world and to connect with others.
