The takeaway is pretty much that none of us - police officers, psychiatrists and interrogators included - is any good at reading people. It would seem to follow that any algorithyms written by people are going to be crap also.
One section of the book is devoted to the Amanda Knox case, convicted of murder almost solely because she did not behave how the police and prosecutors thought an innocent person should act.
