By relying on flawed data from "summary" of Weapons of Math Destruction by Cathy O'Neil

Relying on flawed data is like building a house on a shaky foundation. The data we feed into algorithms shapes their outcomes, so when that data is faulty or biased, the results can be harmful. Take for example the case of predictive policing, where algorithms use historical crime data to forecast where crimes are likely to occur. If the data used is based on biased policing practices, such as targeting certain neighborhoods more heavily than others, then the algorithm will perpetuate those biases, leading to increased surveillance and policing in already over-policed communities. Similarly, in the realm of education, standardized testing data is often relied upon to evaluate teacher performance and student success. However, if the tests are culturally biased or do not accurately measure a student's true abilities, then the data generated will not reflect reality. This can lead to teachers being unfairly judged and students being placed in inappropriate educational tracks, perpetuating inequality rather than addressing it. Flawed data can also have serious consequences in the realm of credit scoring. Algorithms that determine creditworthiness often rely on factors such as zip code, which can be a proxy for race and socioeconomic status. If this data is used without context or nuance, it can result in denying credit to individuals who are perfectly capable of repaying loans, simply because they live in a certain neighborhood. In the age of big data, it is crucial to remember that algorithms are only as good as the data we feed into them. By relying on flawed data, we risk perpetuating and even exacerbating existing inequalities and injustices. It is imperative that we critically examine the data we use and ensure that it is accurate, unbiased, and reflective of the diverse realities of the world we live in.
