Just because the mailing list of individuals was provided to the third-party who administered the survey, it doesn't mean that the results couldn't be given to the AMA anonymously. I guess the reason I assumed it was anonymous is because the second (follow-up) survey actually asked (optionally) for my name and zip code. If they already "knew" who I was, why would they bother to ask that question?
Also, several of the questions in the survey asked IF I was an AMA member, or if I had ever been an AMA member, I wonder how they came up with the, "unique identifying number, if that is the link to your survey, that's your AMA number in part." for those polled who were non-members?
So, I can't say it actually said if it was anonymous or not, nor does it matter as I have nothing to hide, nor do I fear that MY organization would or could use my opinions to my detriment in any way.
