'It is important reading for those who use psychological tests for real-life purposes As usual, Kline succeeds in making the issues clear and interesting I think that this is one of the most important books that he has written in recent years. It deserves to be widely read, particularly by practitioners.' - Colin Cooper, Queen's University Belfast, British Journal of Psychiatry
'This is a remarkable book by a remarkable author. It is also slim, clearly written and presented, but so full of implications for the future continuance of individual differences research, that it is at once mandatory reading for any student or faculty member who claims to be studying individual differences in the manner of an investigative scientist.' - Tom O'Connor, Institute of Psychiatry, Personality and Individual Differences
'One cannot fail to be impressed by the simplicity and clarity of the argument. Its implications for future research cannot be over-emphasised and has already ignited controversy in the field of individual differences ... This is a book that will fundamentally change the way we pursue psychological investigation - buy it and hear Kline's message.' - Cathal McCrory, Queen's University Belfast, British Journal of Educational Psychology
