I used to work at a marketing firm and we did occasional phone survey which I would have to listen in periodically to ensure the questions were understandable and getting good answers.
I was always amazed that anybody would spend 20 minutes answering questions asked by some random person for absolutely no reward. I still don't understand why. And our surveys had to be representative of the area demographics so it was not just all lonely, elderly people. It was people of all ages, race, etc.
If I have time I do it because the person on the other end of the line is probably tired of talking to people who are jerks. I worked in a call center before and it is no fun. These people are just trying to make a living so I try to make their day easier if I have some time to do it.
