Using the ‘Aharonov approach’, Linden and colleagues purportedly prove that reaching equilibrium is a universal property of quantum systems. Such a proof would constitute a very significant result in the foundations of statistical mechanics. I argue that, as it stands, this proof is not sound. However, based on the their theorems, I construct an argument for the conclusion that an arbitrary small subsystem of a large quantum system typically tends toward and remains in, or close to, equilibrium. This is the central result of the article. In the final part of the article, I defend the Aharonov approach against anti-interventionist criticisms.
