An ongoing problem in research in psychology, political polling, and many other areas that rely on asking people questions about their views, activities, and experiences, is that people lie. Sometimes because the topic is a sensitive one, sometimes because they don't like pollsters, sometimes simply as a joke. Whatever the reason, a significant percentage of the people responding to any survey, will lie, and undermine the value of the data you think you're gathering.
This audiobook is about what you can find when you look at the the sources of data where people don't lie, because it would defeat their purpose rather than yours.
