I came across this book in the NYT Book Review, a study of how to manipulate peoples' minds using social media.
Apparently, the psychologists involved taught the usual suspects, Bezos, @Jack, MS, etc how to influence public opinion.
I haven't read the book, but the nine page long review in PDF is enough to give you shivers about what they're capable of doing.
