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 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 0aBig dataxSocial aspectszUnited States. 0aBig dataxPolitical aspectszUnited States. 0aSocial indicatorsxMathematical modelsxMoral and ethical aspects. 0aDemocracyzUnited States. 4aBig datazEstados Unidos 4aAdministración de bases de datosxAspectos sociales zEstados Unidos 4aAdministración de bases de datosxAspectos políticoszEstados Unidos 4aIndicadores sociales xModelos matemáticos 4aDemocraciazEstados Unidos. 0aUnited StatesxSocial conditionsy21st century. 4aEstados UnidosxCondiciones socialesySiglo XXI08iOnline version:aO'Neil, Cathy, author.tWeapons of math destructionbFirst edition.dNew York : Crown Publishers, [2016]z9780553418828w(DLC) 2016016487
