Abstract
Although over 80 studies of various kinds have dealt with opinions on economic issues, the questions raised by the researchers seem to outnumber the answers they have discovered. We know that our students invariably improve their knowledge and understanding of economic principles and concepts when they take a formal course, but we rarely know what happens to their opinions on the many controversial issues as a result of taking such a course. Professor Riddle has gone further than many other researchers in attempting to construct and use a Survey of Opinions on Economic Issues. In this article he describes an experiment to determine whether or not an economics course affected student opinions. He considered such factors as urban or rural background, marital status, and the student's dogmatism score. Finding that opinions did indeed change, Professor Riddle identifies some of the factors related to the changes.
