Kindle. Adam Grant led me to believe this book would have an interesting take on decision making. I read it closely and got bored by its repetition and failure to map well-known techniques for groups to individual circumstances. Recounting the final days of bin Laden and praising story-telling and novel-reading as empathy-building was tendentious at best. I didn't see what Collect Pond and NYC's High Line (cloned by Chicago's The 606 and Sydney's Goods Line, and doubtlessly others) had to do with much of anything. At best a pointer to other works in the area.
Better value are the comments at goodreads.
