The best introduction to personality psychology I have ever read. It is logically organised, very well-written, and scholarly without being pedantic. Best of all, it has a clear focus: it is intended to show readers how they can use data-based personality psychology to make sense out of themselves and their friends and family, and to use that information to improve their lives and their performance -- Robert Hogan, founder and president, Hogan Assessment Systems At last: a fun book on personality that is serious about its science. Absolute must-read for anyone interested in discovering the fascinating psychology of why people do what they do, as well as understanding who we are deep down -- Dr Tomas Chamorro-Premuzic, Psychologist, Author and Chief Innovation Officer, Manpower Group The best introduction to personality psychology I have ever read.
