Consensus reality is that which is generally agreed to be reality, based on a consensus view.
The appeal to consensus arises from the fact that humans do not fully understand or agree upon the nature of knowledge or ontology, often making it uncertain what is real, given the vast inconsistencies between individual subjectivities. We can, however, seek to obtain some form of consensus, with others, of what is real. We can use this consensus as a pragmatic guide, either on the assumption that it seems to approximate some kind of valid reality, or simply because it is more "practical" than perceived alternatives. Consensus reality therefore refers to the agreed-upon concepts of reality which people in the world, or a culture or group, believe are real (or treat as real), usually based upon their common experiences as they believe them to be; anyone who does not agree with these is sometimes stated to be "in effect... living in a different world."
Throughout history this has also raised a social question as to the effects of a society in which all individuals do not agree upon the same reality.
Children have sometimes been described or viewed as "inexperience[d] with consensus reality," though are described as such with the expectation that their perspective will progressively form closer to the consensus reality of their society as they age.
