Cathy O'Neil's TED talk popularizes 'weapons of math destruction' - opaque, high-impact scoring systems - as a caution against ranking people with black-box models.
What you should get from this: Name risks O'Neil associates with harmful scoring systems (for example opacity, scale, and damage) without treating the talk as a complete technical definition.
Watch or know first: None.
AI Expert note: 2017 TED talk; algorithmic-scoring examples (credit, hiring, teacher evaluation) remain relevant to AI ranking tools, though specific systems change.
