Every measurement ever made gave only one result. This means
that unitarity is violated in giving that single result rather
than a superposition. Understanding the reason for this might
require some more work.

I don't claim to have done the work to show how this happens. But
collapse is one possibility.
"Collapse" is certainly the case if you take an epistemic view of the
wave-function: measurment=>new information=>new wave function.
