We live in the age of the algorithm. Increasingly, the decisions that affect our lives—where we go to school, whether we can get a job or a loan, how much we pay for health insurance—are being made not by humans, but by machines. In theory, this should lead to greater fairness: Everyone is judged according to the same rules.
But as mathematician and data scientist Cathy O’Neil reveals, the mathematical models being used today are unregulated and uncontestable, even when they’re wrong. Most troubling, they reinforce discrimination—propping up the lucky, punishing the downtrodden, and undermining our democracy in the process. Welcome to the dark side of Big Data.

Engaging and informative

This book was filled with examples of weapons of math destruction in a variety of fields, which made it accessible and interesting. It also explained things without using much jargon, which made it an easy read. It’s premises were backed by facts and statistics, and it’s argument was persuasive.

Peaking Behind the Curtain of Data Science

Cathy O’Neils work illuminates all of the problems with poorly thought out Algorithms and Models (Weapons of Math Destruction), when unleashed on an unsuspecting public, can deepen divides, falsely reaffirm prejudices, and compound social ills in the pursuit of efficacy. In clear and well written language, O’Neil spells out for the layman and experienced Data Scientist alike, the definition of a Weapon of Math Destruction and its key traits. She also does a great job of providing clear and actionable ways we can spot, prevent, and hold these models accountable. I believe this book is essential reading for everyone in our modern data driven culture. Reminding the builders of their fiduciary responsibility to uphold fairness in their modeling design; and teaching the Everyman how to spot the models and data gathering being applied to them. Wonderfully written and commanding.

Timely and wonderful

This is a wonderful book. You don’t have to love math in order to appreciate the challenges we face in using our vast and expanding computing power for good, while avoiding the bad.
