In *Weapons of Math Destruction* O’Neil offers a look at how algorithms are being used to regulate people. For example, if an inmate is up for parole, a computer algorithm might be used to determine their fate. If you’ve ever wondered how Amazon tells you what “you might like” or how Facebook puts ads in your feed, this book will be useful. Where it is really frightening is how it reveals statistical profiling.
