It is not at all just with pollsters.
Most people I know never answer any call not from a number on their contact list.
You're right. Great point!
I agree. We look at our home phone caller id and if it is out of state or an “unknown number”, we figure, if it is important, they will leave a message. Well, guess what! Robots don’t leave messages. I estimate that if my phone rings 100 times over a few days or a week, we answer no more than 25 or 30 of the calls, where 99% of those are people we know. We LOVE caller ID.
