Book Review: Weapons of Math Destruction

Cathy O’Neil paints a truly harrowing picture of how the promise of big data and big tech to improve the lives of everyone, might only be improving the lives of a few. Algorithms are everywhere and are increasing inequality and driving division in many parts of our lives. Cathy presents data from studies on how algorithms and data are used in a range of systems from the U.S. Justice system to online advertising. She walks the reader through how these algorithms are driving social division and hiding the effects from those who have the most power to affect change. Understanding the limits of algorithms and how they can create institutional bias is an essential first step in creating better systems. Weapons of Math Destruction provides crucial perspective into the failings of big data and reminds us that humans are still the best hope for creating a more inclusive future.
