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

We live in the age of the algorithm. Increasingly, the decisions that affect our lives--where we go to school, whether we can get a job or a loan, how much we pay for health insurance--are being made not by humans, but by machines. In theory, this should lead to greater fairness: Everyone is judged according to the same rules.
But as mathematician and data scientist Cathy O'Neil reveals, the mathematical models being used today are unregulated and uncontestable, even when they're wrong. Most troubling, they reinforce discrimination--propping up the lucky, punishing the downtrodden, and undermining our democracy in the process.

Wie beeinflussen Algorithmen die Entscheidungsfindung der wichtigsten Lebensbereichene? Uni, Job, Kredite, social media und Strafverfolgung werden durch undurchsichtige Programme automatisiert. Wie rassistisch, klassistisch und sexistisch sie sind zeigt Cathy O'Neil in ihrem fantastisch verständlich geschriebenen Buch. Obwohl es ein bedrückendes Thema ist wird es nie schwer zu lesen, sondern bleibt spannend und klärt auf. Klare Empfehlung!

Vor fünf Jahren ohne Frage ein wichtiges Buch gewesen, aber es hat mittlerweile in seinen Beispielen – an denen sich das Buch nun mal entlang hangelt – deutlich an Aktualität verloren.
