                  sufficient personal experience of the
                  alternatives. In everyday life, we rely on
                  recommendations from other people either by word of
                  mouth, recommendation letters, movie and book
                  reviews printed in newspapers, or general surveys
                  such as Zagat s restaurant guides.},
