Facial profiling technology and discrimination: a new threat to civil rights in liberal democracies

This paper offers the first philosophical analysis of a form of artificial intelligence (AI) which the author calls facial profiling technology (FPT). FPT is a type of facial analysis technology designed to predict criminal behavior based solely on facial structure. Marketed for use by law enforcement, face classifiers generated by the program can supposedly identify murderers, thieves, pedophiles, and terrorists prior to the commission of crimes. At the time of this writing, an FPT company has a contract with the United States federal government. After recounting how FPT resurrects the same moral problems associated with the pseudoscience of physiognomy, the author of this manuscript develops and defends the ‘Liberal Argument Against Facial Discrimination’ (LAAFD), which concludes that government use of FPT poses a significant risk of violating the classical liberal value of equality before the law by committing unjust discrimination against groups of people whose faces happen to match FPT classifiers. A key move in the argument suggests how a future scenario that results in widespread discrimination based solely on facial structure could be as unjustified and harmful, mutatis mutandis, as similar discrimination based solely on racial background. In the final section, the author of this paper develops prima facie policy proposals designed to protect classical liberal values if FPT is to be utilized by governments in liberal democratic societies.
