Collective consciousness, collective conscience, or collective conscious (French: conscience collective) is the set of shared beliefs, ideas, and moral attitudes which operate as a unifying force within society. In general, it does not refer to the specifically moral conscience, but to a shared understanding of social norms.
The modern concept of what can be considered collective consciousness includes solidarity attitudes, memes, extreme behaviors like group-think and herd behavior, and collectively shared experiences during collective rituals, dance parties, and the discarnate entities which can be experienced from psychedelic use.
