I donno about this one. But it's a slow day for new threads.

a phenomenon called decoherence, according to which interactions between the quantum states of the system of interest and its environment serve to 'collapse' those states into a single outcome.

My understanding is different. Decoherence is interaction with the environment destroying entanglement - in effect, the environment "factors" an entangled quantum state into independent parts. It does not explain how a mixed state "collapses" to a single outcome.

This is a Darwin-like selection process. "One might say that pointer states are most 'fit'," says Zurek. "They survive monitoring by the environment to leave 'descendants' that inherit their properties."

Laughable nonsense.

"I donno about this one..."

I had doubts because it reads, at first, like New Age mystic commentary.

But, Phys Rev Letters and Nature are serious.
Big Time editing and peer review here. So it should be read carefully.

The point to look for is:
What new experiment or observation is the basis for the headline?
