With an increasing reliance on AI in the fintech industry<\/a> and other sectors comes a significant challenge \u2014 bias. But what is bias in AI?<\/p>\n\n\n\n

From errors in identifying individuals with darker skin tones to hiring algorithms that favor men over women, bias in artificial intelligence isn\u2019t just a theoretical issue; it\u2019s already playing a role in perpetuating stereotypes.<\/p>\n\n\n\n

AI can develop bias mainly through real-world training data that reflects social inequalities and discrimination or unbalanced data that favors privileged groups.<\/p>\n\n\n\n

This article explores how AI inherits prejudices, the risks it poses, and what can be done to ensure fairness in artificial intelligence.<\/p>\n\n\n\n

What is AI Bias?<\/h2>\n\n\n\n

AI bias refers to systematic errors in artificial intelligence systems that result in unfair or discriminatory outcomes. These errors can appear at any stage of AI development, either stemming from biased training data, prejudiced hypotheses in algorithms, or unintended consequences of model deployment.<\/p>\n\n\n\n

Here are some examples of AI bias in real programs.<\/p>\n\n\n\n

Researcher Joy Buolamwini’s work<\/a> revealed that commercial facial recognition systems had higher error rates when identifying individuals with darker skin tones, particularly women. These systems misidentified women with darker skin up to 34.7% of the time, while errors for lighter-skinned men occurred in only 0.8% of cases.<\/p>\n\n\n\n

In 2017, Amazon discontinued<\/a> an AI recruiting tool after discovering it wasn\u2019t rating candidates in a gender-neutral way. The algorithm was trained on resumes submitted over a ten-year period, during which resumes mostly came from men. The system learned to prefer resumes that resembled past successful candidates.<\/p>\n\n\n\n

A 2024 UNESCO and IRCAI study<\/a> found that AI language models, including GPT-2, ChatGPT, and Llama 2, still exhibited gender biases despite mitigation efforts. One model frequently linked female names to domestic roles and male names to professional success, highlighting persistent biases in AI.<\/p>\n\n\n\n

Types of AI Bias<\/h2>\n\n\n\n

AI biases generally fall under three categories: data, algorithmic, and deployment biases, based on where they appear in the development process. Let\u2019s examine these examples of bias in AI:<\/p>\n\n\n\n

Data Biases<\/h3>\n\n\n\n

Data bias happens when the dataset used to train an AI model is incomplete, unrepresentative, or skewed. It can arise from various sources:<\/p>\n\n\n\n

Selection Bias:<\/strong> when the data used to train an AI system does not represent the entire population. For example, an AI system trained on data from one geographic region might not perform well for people outside that group.<\/p>\n\n\n\n

Labeling Bias:<\/strong> when people apply their own judgement when categorizing data. For example, one annotator might consider aggressive political speech unacceptable in a dataset used for hate speech detection, while another might view it as a fair debate. <\/p>\n\n\n\n

Measurement Bias:<\/strong> when incorrect or misleading metrics are used to evaluate an AI model\u2019s performance. If an AI model for hiring is optimized solely for “cultural fit” without considering diversity, it may unintentionally favor people from similar backgrounds, reinforcing workplace homogeneity.<\/p>\n\n\n\n

Reporting Bias:<\/strong> when the data sources that AI learns from don\u2019t reflect actual conditions. This often leads to an overrepresentation of rare events in the data, like extreme opinions and unusual circumstances.<\/p>\n\n\n\n

Confirmation Bias:<\/strong> when AI systems prioritize information that aligns with pre-existing beliefs. For instance, a social media recommendation algorithm may continually suggest content based on the user’s past interactions.<\/p>\n\n\n\n

Algorithmic Biases<\/h3>\n\n\n\n

These biases come from an algorithm’s design, development, or functioning. For example, certain assumptions made in the design process, poorly chosen features, or how certain data types are prioritised:<\/p>\n\n\n\n

Learning Bias:<\/strong> when the choice of model, its assumptions, or the optimization techniques used during training amplify disparities. For example, overly simplistic rules that don\u2019t capture nuances in the data may lead to biases in more complex real-world scenarios.<\/p>\n\n\n\n

Implicit Bias:<\/strong> when AI inherits unconscious biases from human developers, whether through data selection or flawed design choices. Even when developers do not intend to introduce bias, their own perspectives and assumptions can shape AI outcomes.<\/p>\n\n\n\n

Deployment Biases<\/h3>\n\n\n\n

Deployment biases arise when an AI model is applied in real-world settings after it has been developed and trained. Here are some examples of bias in AI:<\/p>\n\n\n\n

Automation Bias:<\/strong> when humans trust AI-generated recommendations even when they are incorrect. This can be dangerous in high-stakes applications such as healthcare or criminal justice, where blindly accepting the AI system\u2019s decisions may lead to incorrect decisions.<\/p>\n\n\n\n

Feedback Bias:<\/strong> when a model\u2019s outcomes and predictions are distorted due to a feedback loop. This occurs when the model\u2019s outputs impact the inputs it later receives, creating a cycle that reflects and even magnifies the initial prejudice in the system.<\/p>\n\n\n\n

Why AI Becomes Biased<\/h2>\n\n\n\n

Although most bias in AI examples demonstrate data-related root causes, AI experts must learn to recognize the potential for bias in all aspects of AI development.<\/p>\n\n\n\n
