Summary of: Weapons of Math Destruction: How Big Data Increases Inequality and Threatens Democracy
By: Cathy O’Neil

Introduction

In the digital age, we often celebrate the benefits brought to us by the internet and Big Data. However, ‘Weapons of Math Destruction’ by Cathy O’Neil presents a dark side to this technological marvel. This book summary focuses on the consequences of using algorithms to shape our lives and societies, from influencing elections to perpetuating inequalities. Through numerous case studies, the dangerous potential of biased algorithms and their unintended consequences on social well-being and democracy will be unmasked.

Internet and Democracy

The internet has been a boon to democracy as it provides a platform for independent voices. However, the same platform could also be used by propaganda machines to manipulate conversations. Social media and search engines are particularly vulnerable to algorithms that can influence the decisions of unsuspecting users. Studies show that political candidates are well aware of the power to garner votes through algorithms that cater to specific profiles. This has profound implications for the ethical use of digital platforms and underscores the need for greater vigilance concerning algorithms designed to influence users.

The Downside of Crime Prediction

Police departments are using algorithms to predict future crime by relying on historical data that highlights where crimes are most likely to occur. The problem is that the police tend to focus on specific kinds of crime – such as vagrancy and certain drug-related offenses – and it tends to occur in poor neighborhoods. As a result, police patrols are concentrated in these areas and leave rich neighborhoods more vulnerable to criminal activity. Consequently, built-in biases skew the data that police use to predict potential violent crimes, leading to innocent people being labeled as dangerous. One of the major issues with this approach is that it can lead to people in poor neighborhoods being labeled as potentially dangerous solely based on the people they follow on social networks and the criminals who happen to live in their neighborhoods. Crime prediction algorithms are designed to protect people but can quickly make people’s lives worse.

Unfair Pricing in Insurance Companies

Insurance companies employ algorithms to determine payment amounts based on customer data, such as credit reports and driving records. In some areas, credit reports are given more weight than driving records, which leads to poor drivers paying more for insurance than rich drivers with a history of drunk driving. This leads to a vicious cycle where cash-strapped families miss payments on bills, worsening their credit score and causing their insurance rates to go up even higher. Some companies even use algorithms to predict whether a customer will shop around for cheaper prices, taking advantage of those who are less likely to do so.
