In "Weapons of Math Destruction," former Wall Street quant Cathy O'Neil exposes how algorithms silently shape our lives - sometimes ruining them. This New York Times bestseller, longlisted for the National Book Award, reveals why elite-built models are quietly perpetuating inequality across society.

Imagine waking up tomorrow to discover an algorithm has determined you're unfit for your job, denied your loan application, or marked you as a criminal risk-all without explanation or appeal. This isn't science fiction; it's the reality exposed in "Weapons of Math Destruction." These mathematical models wield extraordinary power while remaining largely unaccountable, affecting everything from who gets hired to who goes to jail. Consider Sarah Wysocki, a dedicated teacher fired because an algorithm deemed her ineffective. Despite glowing reviews from parents and her principal, she was terminated when the model detected a decline in test scores-failing to account for the fact that her students' previous scores had been artificially inflated through cheating. When Sarah asked how the algorithm reached its conclusion, she was essentially told, "The numbers don't lie." But numbers, divorced from context and human judgment, often tell incomplete stories. This pattern repeats across institutions. In criminal justice, recidivism models transform complex human histories into risk scores that determine sentencing. These models often incorporate factors like zip code and family criminal history-variables that correlate strongly with race and socioeconomic status. The result? A veneer of mathematical objectivity masking the same biases we've struggled with for generations.
