&gt; In the absence of me showing you the evidence, what is your honest estimate of the probability that it&#x27;s true?<p>I have no reason to think that U.S. healthcare, at the high end, is generally superior to that of other rich countries. My guess is that it depends on the field (some do better in, e.g., oncology and others do better in, e.g., brain surgery); that it might vary by hospital or by doctor more than it varies by country; and that results could depend more on operational issues, such as quality control, than on technology or doctor training.
