"Know thyself," said the sage - and this may be the most difficult advice of all. The scientific basis of psychology is often debated, with some arguing that it is a branch of philosophy rather than a true science. But psychometrics, the field of mental measurement, is an area which has been of particular interest to business, educationalists and those interested in personal development alike. Have you ever wondered how intelligent you are compared to your friends and colleagues? Do you know whether you are a numbers person or a words person? How creative are you REALLY?The answers to all these questions and more can be found in this fascinating book. You can scientifically test your verbal or numerical skill, your emotional stability, your assertiveness and, of course, your intelligence.
