Facial recognition technology is fast becoming a fixture in everything from law enforcement to airport security, banking apps to medical diagnostics. But as the technology spreads, so too does a troubling truth: it doesn’t work equally well for everyone. Black communities are disproportionately harmed by the errors and misjudgements baked into the code.
This isn’t just a technical flaw—it’s a mirror of the deeper societal inequalities encoded in the systems that shape our lives. At the heart of facial recognition’s failings is the underrepresentation of black faces in the training data used to build these tools. When algorithms are trained on datasets that skew heavily towards white, lighter-skinned individuals, the technology becomes worse—often significantly worse—at recognising and distinguishing black faces.
The real-world harm to black lives
The consequences go far beyond technical limitations. For black individuals, these biases can have life-altering effects. In policing, biased facial recognition software has led to false arrests, wrongful detentions, and invasive surveillance. There have been numerous documented cases where black men have been misidentified by facial recognition tools and detained for crimes they didn’t commit.
In healthcare, misidentification can have deadly implications. When systems fail to recognise or accurately match patient data for black individuals, it creates disparities in diagnosis and care. In other sectors, such as employment or access control, bias in these tools can result in exclusion, delay, or denial of services.
Each error doesn’t occur in a vacuum. It reinforces stereotypes, worsens systemic inequities, and adds to the over-policing and under-protection of black communities. This is about more than flawed technology—it’s about civil rights and basic human dignity.
Who holds the algorithm accountable?
The issue of algorithmic bias in facial recognition isn’t simply a glitch that can be patched over with code. It’s a structural problem that demands transparency, regulation, and public scrutiny. These tools are often developed in private, tested without sufficient oversight, and deployed without the consent of the people they affect most.
There’s a troubling lack of accountability. Most of the companies behind facial recognition systems are not obligated to disclose how their models were trained or evaluated. This secrecy makes it almost impossible to audit the technology, challenge its fairness, or even understand how decisions are being made.
Moreover, the opacity of these systems allows bias to flourish unchecked. Without clear standards or mechanisms for appeal, those harmed by misidentification have few avenues for recourse. This reinforces a power dynamic where technology serves the powerful while marginalising the vulnerable.
Towards fairer, smarter tech
Solving this problem isn’t simple—but it is possible. It begins with diversifying the training data. Algorithms trained on datasets that reflect the full spectrum of human diversity—across race, age, gender, and more—are more likely to perform fairly and accurately. Data inclusion is not a luxury. It is a necessity.
However, data diversity alone isn’t enough. There must also be rigorous testing to identify and correct bias before deployment. Just as pharmaceuticals are tested for side effects across different populations, so too must AI systems undergo thorough, standardised evaluations for fairness across demographics.
Transparency must also be non-negotiable. Developers and companies should be required to publicly disclose how their models work, what data was used, and how performance varies across groups. Independent audits, regular impact assessments, and real-world monitoring should all be part of the process.
A role for policymakers and communities
Policymakers must act decisively to create legal and ethical guardrails. This includes enacting legislation that ensures AI systems, particularly those used in sensitive areas like policing or healthcare, meet clear fairness and transparency standards. There must be legal consequences for systems that cause harm or perpetuate discrimination.
But regulation alone is not enough. Black communities—those most affected—must be at the centre of the conversation. Their lived experiences, concerns, and insights are crucial for developing technology that truly serves everyone. Community engagement, inclusive design, and participatory governance are essential elements of ethical AI.
This also means building spaces where civil society, ethicists, technologists, and impacted communities can come together to shape the rules and standards guiding facial recognition systems. Ethical AI isn’t just about good coding—it’s about listening, adapting, and ensuring technology works for the many, not the few.
A future AI must serve everyone
The fundamental question is this: who does technology serve, and at whose expense? As things stand, facial recognition software often serves power—whether in the hands of police, corporations, or state actors—at the expense of the marginalised. This is not just an ethical failure but a societal one.
But the good news is that it doesn’t have to be this way. By acknowledging bias, we take the first step towards fixing it. By involving diverse voices in design, we begin to rebalance the scales. By holding systems accountable, we lay the groundwork for trust. And by embedding justice, equity, and human rights at the heart of AI development, we create technologies that uplift rather than oppress.
Tech as a tool for equity
The fight against facial recognition bias is part of a broader struggle for a more inclusive and equitable digital future. One in which no one is left behind or wrongly targeted because of the colour of their skin. One in which innovation and ethics go hand-in-hand.
If we are to harness the transformative potential of AI, we must confront its flaws head-on. Developers, researchers, policymakers, and communities must work together to build systems that reflect the best of our humanity—not the worst of our prejudices.
The path forward is not only possible—it is necessary. For too long, black communities have borne the brunt of technological oversight. Now is the time to demand fairness, embed justice, and ensure that technology becomes a force for equality, not exclusion.
