I always tell my friends (perhaps jokingly) that "the answer is always evolution", and I agree with what Egyptian Pharmacist and Science writer Shadi AbdulHafiz once said: "you can't understand the world properly except in the light of evolution, quantum physics, and calculus". I do think this book does indeed start explaining our behavior and tendencies in built environment based on evolution and I've seen previous research for the author regarding that, which I do really like...
BUT
perhaps except for the first one or two chapters, the book is mainly based -in my humble, critic-able, view- about evolutionary psychology mainly, and I to be honest I don't think evolutionary psychology is that much of a solid ground to link architecture and the urban to behavior.
For example, the first chapter (edges matter) speaks about the anatomy and physiological history of humans, and how, therefore, they relate more to lower level edges. Makes sense. Compare to chapter 5, Storytelling, where not a single research is referenced, and sounds more like a phenomenological description than a proper "cognitive" explanation. Mhmm..
I do agree with the author's quote of Steve Jobs 'The broader one's understanding of the human experience, the better design we will have.", and her final words on design theory and policies. I think this field needs more research (I am writing a dissertation about a related topic), and this book is an appreciated kick-start.
