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 car loan, how much we pay for health 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.

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

But as Cathy O’Neil reveals in this urgent and necessary book, the opposite is true. The models being used today are opaque, unregulated, and uncontestable, even when they’re wrong. Most troubling, they reinforce discrimination: If a poor student can’t get a loan because a lending model deems him too risky (by virtue of his zip code), he’s then cut off from the kind of education that could pull him out of poverty, and a vicious spiral ensues. Models are propping up the lucky and punishing the downtrodden, creating a “toxic cocktail for democracy.” Welcome to the dark side of Big Data.

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 résumés, grant (or deny) loans, evaluate workers, target voters, set parole, and monitor our health.

O’Neil calls on modelers 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.

Weapons of Math Destruction

5 stars

O'Neil is an excellent guide to the world of algorithms and how they impact our lives in ways large and small. To me one of the most depressing lessons of the book was that the people creating these systems which analyze data have almost no interest in the knock-on effects that their work has on people's lives. They are so focused on whatever particular goal they have that they have total blinders as to the damaging effects that their work might have. As with any book about technology the companies have changed a bit since O'Neil wrote the book, but the underlying problems have not changed; thus this continues to be a worthy guide to the challenges that our society will face as we continue to be enmeshed in algorithms which may not have our best interests at heart.

Suit up for Combat!

5 stars

This was an exceptional book. It's not heavy into statistics but gives the rationale for what is a WMD (Weapon of Math Destruction) and WMDs maybe a new term but we have been under the exploitation of WMDs well before we think. It's not a new phenomenon but it is one that we should be aware of.

Take a read and learn how about them so that we can all do better to combat them and use math to not only help describe the world but make it a better place to live in.

Review of 'Weapons of Math Destruction' on 'Goodreads'

2 stars

Humans tend to make models of everything. We even have our own models in our head that ease our way through life.
The models pointed in this book are biased. And that is because they are modeling a system that is biased. They only reflect the view of the world of the people that design them. It's true that they are unfair, but because the capitalism is an unfair system.
I agree with the author in that we must be vigilant and fight against this discriminating models. But I think that this tools only make the unfairness of the system more efficient. The problem is deeper than the tool, we must fight the system for a better and more fair world.
