Are you the victim of “weapons of math destruction?” Data scientist Cathy O’Neil explains why you likely won’t remain unscathed by biased algorithms. O’Neil urges society to demand more from the companies that design algorithms and to challenge the dangerous myth that algorithms are fair and objective. getAbstract recommends this impassioned, witty talk to data scientists, consumers, employers and employees everywhere.

In this summary, you will learn

  • How data scientists build algorithms;
  • How this process introduces bias;
  • How hidden, biased algorithms can become “weapons of math destruction”; and
  • How to test any algorithm for integrity, accuracy and fairness.
