The
many-minds interpretation of
quantum mechanics extends the
many-worlds interpretation by proposing that the distinction between worlds should be made at the level of the
mind of an individual observer. The concept was first introduced in 1970 by
H. Dieter Zeh as a variant of the
Hugh Everett interpretation in connection with
quantum decoherence, and later (in 1981) explicitly called a many or multi-consciousness interpretation. The name
many-minds interpretation was first used by
David Albert and
Barry Loewer in their 1988 work
Interpreting the Many Worlds Interpretation.
