Three job candidates of differing gender and ethnicities under a magnifying glass

Artificial Intelligence (AI) has become an invaluable tool in modern hiring processes, offering efficiency and scalability that manual methods often cannot match. However, as with any technology, AI is not without its pitfalls. One significant concern is the potential for AI tools to inadvertently perpetuate hiring biases, particularly in regard to people with disabilities. Understanding and implementing strategies to mitigate these biases is crucial for HR and for Diversity, Equity, Inclusion, and Accessibility (DEI&A) professionals.

Training Data Bias

AI systems learn from historical data, which can be inherently biased. If the training data contains discriminatory patterns, such as gender or race bias, the AI model may replicate these biases in its decision-making process. For instance, if past hiring decisions favored certain demographics over others, AI is likely to continue this trend. This issue underscores the importance of using diverse and representative data to train AI systems.

Algorithmic Bias

The algorithms underlying AI tools can also introduce bias. For example, if an algorithm gives higher scores to resumes/CVs featuring keywords like “aggressive” or “assertive,” it may unintentionally favor male candidates over female candidates (men are more likely to include those keywords in their applications)  thereby perpetuating gender bias. Such biases can emerge from the underlying assumptions in the algorithm’s design. This highlights the need for careful scrutiny and testing of algorithms to ensure fairness.

Feature Selection Bias

AI models use various features, such as education, experience, or specific skills, to make predictions. However, if these features are biased—favoring certain educational institutions or industries—the AI tool may inadvertently discriminate against certain groups. This bias can be particularly insidious as it often stems from deeply ingrained societal norms and values which are then reflected in the existing hiring data.

Feedback Loop Bias

AI systems evolve by learning from feedback. If the human evaluators providing this feedback are biased, these biases can be reinforced and magnified in the AI decision-making process. This feedback loop can lead to a self-perpetuating cycle of discrimination, so it's essential to ensure that feedback mechanisms are free from bias.

Lack of Transparency

Some AI models operate as complex “black boxes,” making it difficult to understand how they arrive at specific decisions. This lack of transparency can obscure biases and hinder efforts to hold these systems to account. Transparency in AI decision-making processes is crucial for identifying and addressing potential bias.

Data Imbalance

When training data lacks diversity—such as an under-representation of certain demographics—the AI model may struggle to make fair and accurate predictions for those groups. This data imbalance can lead to skewed outcomes that disproportionately disadvantage underrepresented groups, emphasizing the need for comprehensive and inclusive datasets.

Human-AI Interaction Bias

Interactions between humans and AI tools can introduce bias as well. For example, during interviews conducted by AI chatbots, the biases of human evaluators can influence the AI’s responses. If evaluators exhibit a preference for candidates from specific backgrounds, the AI may learn to mimic this preference, thereby perpetuating bias.

Mitigating AI Bias in Hiring

To address biases, organizations must take proactive steps:

1.   Curate Diverse Training Data

Ensuring that training data represents a wide range of backgrounds and demographics is fundamental. Diverse datasets help AI models learn to recognize and fairly evaluate candidates from various groups, reducing the risk of perpetuating existing bias.

2.   Regularly Audit Models

Continuous assessment and auditing of AI models are essential to identify and correct bias. Regular audits help detect discriminatory patterns early, allowing for timely intervention and adjustment of the AI’s decision-making processes.

3.   Provide Transparency

Making AI decision-making processes more transparent is critical. Transparency enables organizations to identify and address biases, fostering accountability and trust in AI systems. Request this information from the producer of your tools.

4.   Involve Diverse Stakeholders

Including diverse perspectives in the development and evaluation of AI systems. This can significantly reduce bias, as diverse stakeholders bring varied experiences and insights. This helps identify and mitigate potential biases, which may otherwise be overlooked by a more homogenous group.

Don’t lose sight of the positives while eliminating the negatives

AI tools have the potential to revolutionize hiring processes, but they are only as unbiased as the data they are trained on, and the algorithms they employ. HR and DEI&A professionals must be vigilant in recognizing and addressing the biases that AI can introduce.

By curating diverse training data, regularly auditing models, providing transparency, and involving diverse stakeholders, organizations can work towards creating fair and equitable hiring processes that leverage the benefits of AI while minimizing its drawbacks.
