'Grounded in measurement theory but with numerous applications to the extant literature in traffic safety research, Prof. WÃ¥hlberg reminds us that the value of our scientific endeavors is only as good as our standards of evidence. This provocative work underscores the extent to which future advances in understanding and predicting safety outcomes rely on self-critical examination of the assumptions, methods, and analyses in which we drape our conclusions ... even when it becomes apparent that the emperor simply has no clothes.'
