 Finally, one can show that an observer who repeats a measurement on an infinite sequence of systems in the same initial state will approach a state where he reports that his measurement results were randomly distributed with the standard quantum relative frequencies (when in fact he got no ordinary determinate results for any of his measurements). This is the feature of quantum mechanics without the collapse postulate that Everett himself found the most compelling. (See Albert (1992) and Barrett (1999) for further discussion of the suggestive properties of the bare theory. See Everett (1956, 129–30), (1955, 67), (1956, 121–3 and 130–3), and (1957, 186–8 and 194–5) for his discussions of these properties.)
