Weapons of Math Destruction: How Big Data Increases Inequality and Threatens Democracy

A former Wall Street quant sounds an alarm on the mathematical models that pervade modern life - and threaten to rip apart our social fabric

We live in the age of the algorithm. Increasingly, the decisions that affect our lives - where we go to school, whether we get a loan, how much we pay for insurance - are being made not by humans, but by mathematical models. In theory, this should lead to greater fairness: everyone is judged according to the same rules, and bias is eliminated.

And yet, as Cathy O'Neil reveals in this urgent and necessary book, the opposite is true. The models being used today are opaque, unregulated, and incontestable, even when they're wrong. Most troubling, they reinforce discrimination. Tracing the arc of a person's life, O'Neil exposes the black box models that shape our future, both as individuals and as a society. These "weapons of math destruction" score teachers and students, sort CVs, grant or deny loans, evaluate workers, target voters, and monitor our health.

O'Neil calls on modellers to take more responsibility for their algorithms and on policy makers to regulate their use. But in the end, it's up to us to become more savvy about the models that govern our lives. This important book empowers us to ask the tough questions, uncover the truth, and demand change.

This book spent a lot of time telling stories and avoided taking a deeper dive on data science. A lot of this would have been better suited to a series of longer blog posts. If you’re interested in data science and how it’s affecting the world around us, I would suggest looking elsewhere. Read full review

A chilling analysis of the big data algorithms that rule our society in ways we don’t always realise, and how their results impact us negatively, increasing inequalities and injustices in groups where ... Read full review
