**Decoherence relationship to the "measurement problem"**

I have heard the argument that "decoherence" in quantum states causes the quantum collapse to occur, and that this solves the "measurement problem". But I'm still left with a nagging question... Does decoherence only produce quantum collapse when there is an observation made of the quantum system with sufficient specificity to identify the decoherence. If so, how can that possibly be considered a solution to the "measurement problem"?Sent from my iPhone using Physics Forums
