Fortunately, David Catron explains the problems with the survey methodology:
The lead author of this "survey" is Aaron E. Carroll, a single-payer zealot on the Board of the activist group "Physicians for a National Health Program."Catron also notes that the PNHP website itself states:
This guy routinely produces "studies" and "surveys" that somehow always show that Americans in general and the medical community in particular want government-run health care.
About 500 questionnaires were undeliverable, 197 were returned by physicians no longer in practice, and 2,193 were completed (51% response rate) and returned to Drs. Carroll and Ackermann.Catron concludes:
Anyone with a basic understanding of statistical samples will see a red flag here. Surveys of this type are worthless if the sample isn't random, and this one doesn't pass that test. The 2,193 respondents obviously constitute a self-selected group and, as such, are not representative of the larger population of physicians.
Dr. Carroll knows this, of course, yet he disingenuously foists this fraud on the public.
