Several calls from that number for a few days. Finally picked up today and the woman leaped right into the "health care survey for the Commonwealth of Massachusetts" and then said, "Why don't we get started?" and then rattled off some age groups, one of which I was meant to pick as mine. I told her I had to turn down music and that I had barely heard the groupings and who was conducting the survey again? She said, "It's for the Commonweatlh of Massachusetts to see how we can get healthcare costs down in your area" and launched into another section of her pitch which was the dispiriting fact that it would take 20 minutes depending how I answered the questions for my household. Again, I said, "Who is conducting this, the Mass Department of Public Health" (she grunted somewhat affirmatively) and then I added that I didn't have that much time. By now she was sounding really on edge about my wanting to know who was conducting the survey, so she bailed by saying she'd try again another time, as if the limitation was my time and not the fact that she wouldn't say exactly who she was conducting the survey for. I never even got around to pointing out that she hadn't done any sort of informed consent process.
