In Weapons of Math Destruction, O’Neil demonstrates the harmful ways in which algorithms can influence the outcomes of many common events in life. Specifically, O’Neil examines how these algorithms operate on inappropriate criteria and she examines the consequences of this misuse for the large number of people evaluated by these algorithms. Throughout the text, O’Neil uses the abbreviation “WMD” to refer to the algorithms she describes as “Weapons of Math Destruction”, and this convention is maintained in this review of her book. In her book, O’Neil examines and proves how algorithms have “learned from the humans how to discriminate, and … carried out this work with breathtaking efficiency” (116). In order to review this book in a comprehensive …show more content…

In this way, the themes of her argument are strongly supported. A common theme in O’Neil’s book is the idea of the harmful feedback loop that many WMDs maintain. O’Neil argues that too often, the implementation of algorithms allows them to “define their own reality and use it to justify their results” (7). Because they are not properly adjusted after producing wrong results, these algorithms are static and cannot grow or learn. Therefore, over time, they become self perpetuating by producing results that align exactly with the assumptions made when formulating the algorithm. When these results are used to influence people, like when used as a part of predictive policing, humans can use the results of the algorithm to justify punishing the people selected by the algorithm. With many static algorithms the results are often misused to prove that the results themselves have …show more content…

Algorithms are used to sort through massive amounts of data, and when this data represents people, it is often the poor. Algorithms target the disadvantaged. Algorithms are often unescapable for the disadvantaged masses, while richer people can usually afford to have their data processed by people, not by algorithms. This is not usually an explicit option, but rather due to the fact that business who use WMDs use them because they are amazingly efficient and are able to process all the data from the general population the business interacts with. Any outliers to this general population usually receive specialized attention if they are important to the business (and rich people usually are) or if they can otherwise enact legal action (which requires greater wealth) against the business if they feel that they have been discriminated against by the algorithm. O’Neil states that when it comes to WMDs, privacy is “a luxury that only the wealthy can afford” (170). O’Neil establishes that profit is a commonly used proxy for the truth when evaluating the success of an algorithm, and that business always seek to increase profit. Therefore if an unfair algorithm increases profit, a business has no reason to change it unless prompted to by legal action. WMDs are used to increase efficiency, and as a result often cause the secondary outcome of “industrial production of unfairness”
