Artificial Intelligence (AI) bias is similar to the visible tip of an iceberg, representing only an observable, fractional part of a much larger problem. Beneath the surface lies a vast, hidden structure of systemic and historical biases that prevail over humanity. These societal biases shaped by cultural, economic, and political inequalities are the foundational layers from which AI inherits and perpetuates its prejudices. The visible manifestations of bias in AI are merely symptoms of these entrenched societal issues. Continued reliance on such biased models can potentially deepen pre-existing social disparities, amplifying the structural inequalities they mirror.
This complication is exemplified in the operation of recidivism prediction algorithms, which have come under scrutiny for perpetuating systemic racial biases despite their increasing adoption across judicial systems. Empirical studies have revealed concerning patterns of inequity within such systems, notably in Northpointe’s widely used COMPAS (Correctional Offender Management Profiling for Alternative Sanctions) algorithm. A detailed analysis of COMPAS demonstrated that Black defendants were disproportionately classified at higher risk for recidivism compared to their actual behavior, highlighting a significant overestimation of risk. In contrast, White defendants were frequently classified as lower risk, even when the case was otherwise, thereby underestimating their likelihood of reoffending.
This inherent bias is not confined to the criminal justice sector; it extends into other domains such as employability, where algorithms are increasingly used by organizations to evaluate candidates for various job roles. The outcomes of such algorithms are often influenced by factors that should be irrelevant, such as an individual’s dialect. This interplay between algorithmic judgments and sociolinguistic factors, along with its broader consequences, will be analyzed in subsequent sections. Furthermore, it has also been reported that Face Recognition tools have failed to even detect the faces of people of colour, and are recognised only when white masks were donned!
The integration of AI into the healthcare sector has demonstrated its potential benefits while simultaneously amplifying its inherent biases, which adversely impact both the healthcare system and its consumers. Although the transition from dismantling Race-Based medicine to adopting Race-Conscious medicine has been widely advocated, race continues to function as a variable in numerous contexts. In the seminal Study by Obermeyer, Powers, Vogeli, and Mullainathan revealed that widely used algorithms, such as those in the United States’ "high-risk care management" programs, produce racially biased outcomes. These models rely on healthcare expenditure as a proxy for illness severity, overlooking systemic disparities that result in lower spending on Black patients despite equivalent medical needs. Consequently, Black patients are less likely to be identified for proactive care, perpetuating racial inequities in healthcare access and resource allocation.
Although conspicuous errors are readily identifiable and correctable, they fail to address underlying systemic issues. Bias in AI systems can manifest in subtle yet impactful ways, producing outputs that reinforce covert prejudices. Research conducted by Hoffmann, Kalluri, Jurafsky, and King has demonstrated that dialectal variation serves as a key factor influencing Natural Language Processing (NLP) models to produce responses shaped by colonial stereotypes. For example, African American English (AAE), a dialect predominantly spoken by descendants of enslaved African Americans in the United States, was discriminated across various domains, including judicial, educational, and economic spheres. Although overt expressions of prejudice and discrimination have diminished from the Jim Crow period, these discriminatory tendencies persist in more covert forms, extending into technological domains such as Artificial Intelligence.
Using the Matched Guise Probing Method, an indirect approach to assessing language attitudes, researchers contrasted perceptions of African American English (AAE) and Standard American English (SAE). In this experiment, the race of the speaker was deliberately withheld to isolate the linguistic variable, ensuring that observed differences in model predictions stemmed exclusively from the AAE–SAE contrast. Notably, this subtle experimental design revealed that language models perpetuate raciolect-based stereotypes, primarily negative, in covert contexts. Conversely, the same models generated more positive stereotypes in overt scenarios. Strikingly, this pattern was consistent across all evaluated language models, highlighting the pervasive nature of implicit bias in NLP systems.
A prevalent misconception persists that feeding Artificial Intelligence systems with gallons of data will render them reliable and trustworthy. If such an assumption held true, the aforementioned scenarios, along with numerous other instances of algorithmic bias, would not exist. Advocates of this notion, ought to be cognizant of the inherent problematics of the datasets used to train these algorithms. Reid Blackman, author of Ethical Machines, states, “AI is a software that learns by examples.” Consequently, a proportionate relationship emerges: when algorithms are trained on flawed or biased data, they inevitably produce flawed and biased outcomes. This can be observed in the application of facial recognition technology within law enforcement practices in the United States. These algorithms are often trained on mugshot datasets in which Black individuals are disproportionately represented. This overrepresentation perpetuates a cycle wherein the flawed social system generates flawed data, targeting groups. Furthermore, algorithmic bias can also arise from faulty designing of models, where certain variables are disproportionately weighted without accounting for the social contexts that influence these variables. For instance, as previously mentioned, healthcare algorithms have exhibited bias by attributing higher weightage to healthcare spending, overlooking systemic disparities in access and care. Similarly, biases may emerge from the use of proxies, which are indirect variables that inadvertently reflect other attributes, such as race or gender, as evidenced in dialect-based prejudices exhibited in algorithms.
Rather than addressing user concerns and complaints through piecemeal, whack-a-mole fixes, technologists must develop a deeper sensitivity to societal challenges and prioritize the development of algorithms that do not exacerbate existing social inequalities. Meaningful engagement with society is essential for emerging technologists to critically and ethically analyse the data employed in the creation of algorithms. To this end, the integration of interdisciplinary units on gender, caste, race, class, and environmentalism, among others, should be a mandatory component of STEM curricula. Such an approach would ensure the cultivation of social consciousness and ethical responsibility in technologists.
Constant awareness and societal engagement are crucial for achieving more equitable representation in datasets, the optimized development of models, and the precise attribution of weight to variables. These efforts collectively contribute to the creation of algorithms that are not only more accurate but also more reflective of diverse societal realities.
