In the acknowledgments the authors expressed thanks "for encouraging us to 'geek out' in our stories, trusting that readers would be turned on, not turned off, by the depth of science we covered." I learned about many interesting studies I hadn't been aware of before reading the book. Bodrova and Leong's Tool Of the Mind work about cognitive self-control was especially intriguing.
