  Currently there are two main approaches to describe how quantum statistical
physics emerges from an isolated quantum many-body system in a pure state:
Canonical Typicality (CT) and Eigenstate Thermalization Hypothesis (ETH). These
two approaches has different but overlapping areas of validity, phenomenology
and set of physical outcomes. In this paper we discuss the relation between CT
and ETH and propose a formulation of ETH in terms of the reduced density
matrix. We provide strong numerical evidences for the proposal.
