It is hard to interpret quantum mechanics. The most surprising but also most parsimonious
interpretation is the many-worlds or quantum-multiverse interpretation implying a permanent
coexistence of parallel realities. Could this perhaps be the appropriate interpretation of
quantum mechanics? This book collects evidence for this interpretation both from physics and
from other fields and proposes a subjectivist version of it the clustered-minds multiverse.
The author explores its implications through the lens of decision making and derives
consequences for free will and consciousness. For example free will can be implemented in the
form of vectorial choices as introduced in the book. He furthermore derives consequences for
research in the social sciences especially in psychology and economics.
