“Weapons of Math Destruction: How Big Data Increases Inequality and Threatens Democracy” by Cathy O’Neil is a compelling exploration of the dark side of big data and algorithmic decision-making. O’Neil, a former data scientist, delves into the ways in which mathematical models, when improperly wielded, can reinforce and exacerbate social inequalities. Through insightful examples and real-world cases, she illustrates how algorithms can lead to destructive outcomes, impacting various aspects of society, from education and employment to criminal justice. O’Neil argues that these “weapons of math destruction” are not neutral tools but can embed and perpetuate biases, amplifying existing societal disparities and threatening the principles of fairness and democracy.
