Get the Summary of Cathy O'Neil's “Weapons of Math Destruction” in 20 minutes. Please note: This is a summary & not the original book. Original book introduction: 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.
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 troublingly, 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.
