"Too often early childhood policy is founded on dogmatic interpretations of over-simplified science. Skepticism is the antidote, which this remarkable piece of scholarship provides, bringing ethical concerns to the fore." John Bruer, President Emeritus, James S. McDonnell Foundation "Forensically detailed, compelling and at points unsettling, this book is a very welcome antidote to simplistic policy appropriations of biology. It deserves to be widely read." Val Gillies, Professor of Social Policy and Criminology, University of Westminster
