So the thread about how many people don't know who the US gained independence from made me think of this.
Would you agree to answer poll questions over the phone?
Would it matter if it was your home phone or cell phone? Would you answer the questions honestly and to the best of your ability, even if they were inconveniencing you? Would the time that they called matter?
For me, I probably wouldn't agree to answer poll questions over my cell more than half the time (I don't have a home phone). Those times that I would answer the poll, I would probably answer as quickly as I could, so I'm not promising that my answers would absolutely be "to the best of my knowledge".
