Some 20 years ago as I was finishing graduate school, I worked for a polling company. It was longer than I wanted to but it gave me some valuable insights on that business before I moved into the line of work that I wanted. I got to know the man who ran the company; he ran polls for national and international companies and occasionally dabbled into political polling. He was meticulous and it became very clear that this job was his life. Now I don’t know his politics but I would guess that he was left of center, at least on social issues. However, he was nearly fanatical about being impartial and getting the true response. Some twenty years later, all of this helps me to understand how political polling works, and believe me it is very difficult. In other words, if political polling isn’t done exactly right it becomes a terrible slanted mess.
Here’s how live polling works. Automated computer dialers call randomly generated phone numbers, which are often are disconnected, faxes and or not in service. In a four hour shift you would be lucky to get 8-10 complete surveys per poll taker in a hotly contested political race. Now mind you that was 20 years before cell phones, my understanding is that now because of cell phones and caller id many polling agencies are using brief computer automated voices to ask questions. Most polling agencies have given up on live survey results on such things as your favorite bar of soup, breakfast cereal, shoe company etc. Believe me there were nights that we would put in a four hour shift and call over 150 people and get one or two complete surveys concerning your favorite shampoo.
When it comes to political polling my old boss (who is a Ph.D and widely respected across the country) would fret about the way we ask each question, our tone and our attitude. He would drill into us that he needed unbiased surveys for his clients. He would remind us, and this is very important in today’s world, that conservative oriented people don’t like polling as much as liberals because liberals believe in proselytizing their views while conservatives feel their views are a reflection of their values, as well as their cultural and religious upbringing. This is why liberals tend to be oversampled in polling. By and large they don’t hang up on pollsters and surveys because they view it as their duty and mission to get the word out. Again, my boss was not a conservative and he could see this 20 years ago.
