Surveys are interesting in several ways.
They are interesting to those who want to use them to see what people think about a certain issue, tracking changes in societal attitudes. They are interesting to politicians in search of their next passionate commitment. They are interesting to me in the amazement that so many people think surveys are worth much. However, despite my jaded attitude, there are some things of legitimate interest in public opinion surveys. It is interesting that surveys of professing evangelical Christians have shown that the majority have never once shared their faith with anyone.
