The Great Psychology Delusion Missteps, Pitfalls and How to Make a More Successful Psychological Science

'Speelman and McGann's critique of the assumptions that underlie much contemporary research in psychology reveals the flaws that have impeded its development as a science. This book is a major work that should reform research practice in the field.'

Geoff Hammond, Emeritus Professor, University of Western Australia

'The book by Speelman and McGann has many nuggets of wisdom of which my favorite is their aggregation delusion, and additional delusions follow. I recommend the book for those who wish to become better researchers or better research consumers.'

David Trafimow, Professor, New Mexico State University

'Given its subject matter, I wasn't expecting to feel so invigorated, inspired, and hopeful about psychology once I'd finished reading. Speelman and McGann offer an incisive dissection of psychology's current ills, and a thoughtful discussion, with workable solutions, for how we can remedy them. I cannot recommend this book highly enough - everyone even remotely interested in psychology should read it.'
