65 - The Metrics That Matter

In this book, Cathy O'Neil explores the societal impact of big data algorithms, which she terms 'Weapons of Math Destruction' (WMDs). These algorithms are used in various fields such as insurance, advertising, education, and policing, and they often reinforce discrimination, amplify inequality, and harm the poor. O'Neil argues that these models are opaque, unregulated, and difficult to contest, leading to a 'toxic cocktail for democracy'. She calls for greater responsibility from modelers and policymakers to regulate these algorithms and for the public to become more aware of their impact. The book provides numerous examples of how these models can go wrong and emphasizes the need for ethical considerations in the use of big data models.
