There are four commonplaces that I am not sure how to mesh together, or if this is not possible, which one(s) is/are an () oversimplification(s)/wrong, and why.(adsbygoogle = window.adsbygoogle || []).push({});

(1) the wavefunction is deterministic.

(2) a collapse or decoherence or splitting into worlds (take your choice) makes the wave function lose information,

(3) which value the wave function takes on when measured cannot be derived

(4) all quantum processes are reversible

(5) information is never lost (except maybe via a black hole).

(2) and (5) directly contradict each other,

(2) and (4) indirectly contradict each other,

(1) and (3) directly contradict each other

So, what is wrong?
