  Even a century after the formulation of Quantum Mechanics (QM), the wave
function collapse (WFC) remains a contentious aspect of the theory.
Environment-induced decoherence has offered a partial resolution by
illustrating how unitary evolution in an open quantum system can lead to
effective WFC within its components. However, this approach by itself does not
lead to a fully self-consistent reformulation of QM. We introduce a modified
set of QM postulates, which exclude both WFC and Born's probability rule. They
are replaced with the Maximum Entropy Principle, a weaker postulate that
specifies conditional probabilities for mutually compatible observations.
Within this formulation, both WFC and Born's rule become emerging properties.
