Black Box or Glass Box? The High-Stakes Trade-Offs in AI Model Development
Black Box or Glass Box? The High-Stakes Trade-Offs in AI Model Development
As organisations race to harness the power of machine learning (ML), they face a critical tension: how to deliver high-performing, innovative AI products while ensuring those systems are interpretable, transparent, and aligned with business and regulatory demands.
This tension is not just a technical or ethical issue, it is increasingly a matter of legal and financial survival.
“There’s no question we are in an AI and data revolution, which means that we’re in a customer revolution and a business revolution. But it’s not as simple as taking all of your data and training a model with it. There’s data security, there’s access permissions, there’s sharing models that we have to honour. These are important concepts, new risks, new challenges, and new concerns that we must figure out together.”
—Clara Shih, CEO, Salesforce AI
The Three Pillars: Performance, Interpretability, and Business Model
Model Performance
AI’s promise lies in its ability to uncover patterns, automate decisions, and deliver insights at scale. High-performing models—especially deep neural networks and ensemble methods can achieve remarkable accuracy, but often at the cost of becoming "blackboxes"whose internal logic is inscrutable even to their creators.
Interpretability
Interpretability is the ability to understand and explain how an AI model arrives at its decisions. In high-stakes domains, this is not a luxury but a necessity. Interpretability builds trust, enables regulatory compliance, and allows organisations to detect and correct errors or biases before they cause harm.
“The ethical AI principle of ‘interpretability’ calls for designing systems that can provide human-understandable reasons for their outputs.”
— AI Ethics Guide
Business Model
The way AI companies monetise their products, whether through SaaS, data-driven services, or embedded solutions can be directly affected by demands for transparency. Customers, regulators, and courts increasingly expect not just results, but explanations.
“Harnessing machine learning can be transformational, but for it to be successful, enterprises need leadership from the top."
This means understanding that when machine learning changes one part of the business, the product mix, for example, then other parts must also change.”
—Erik Brynjolfsson, Stanford Institute for Human-Centered AI
The Regulatory and Legal Landscape
Explainability as a Legal Requirement
Regulators worldwide are moving to require explainability in AI systems, especially those used in high-risk applications. The EuropeanUnion’s General Data Protection Regulation (GDPR) enshrines a"right to explanation" for individuals subject to automated decisions, while the new EU AI Act mandates transparency and documentation for high-risk AI.
In the U.S., sectoral regulations and the AI Bill of Rights emphasise notice, explanation, and human oversight .
Litigation Spotlight: When Black Boxes Go to Court
The inability to explain AI decisions is no longer just a theoretical risk. It is a growing source of litigation and regulatory action.
UnitedHealthcare & Humana: Both companies face class-action lawsuits for using opaque AI algorithms (nHPredict) to deny or curtail patient care. Plaintiffs allege the models were error-prone, overrode clinical judgment, and lacked transparency, leading to wrongful denials and significant financial harm. The UnitedHealthcare case alone could involve billions in damages, with the lack of explainability central to the claims.
Workday (Hiring): Facing a lawsuit alleging its AI-powered hiring tool discriminated based on race, age, and disability. The case raises questions about vendor liability and the risks of unexplainable AI in employment decisions.
State Farm (Insurance): Sued for alleged discrimination in claims processing, with plaintiffs arguing that the AI-driven process led to disparate outcomes for Black homeowners, highlighting the risks of opaque models in high-stakes insurance decisions.
Meta Platforms: The U.S. Attorney’s lawsuit against Meta for discrimination in advertising algorithms highlights the legal risks associated with non-interpretable AI systems, as the inability to explain algorithmic decisions is a central issue.
"AI tools pose a 'black box' problem in which the tool masks the exact details of the internal processes, including decision-making. The lack of transparency can blur evidence of discrimination, effectively restricting disparate impact claims."
— Legal analysis on AI and the legal profession.
Doshi-Velez & Kim (2017),
"In high-stakes domains such as healthcare and criminal justice, interpretability is often considered a necessary property for models to be adopted."
The Business Impact of Interpretability
Trust, Adoption, and Market Success
Interpretability is not just about compliance. It is a driver of business value. Customers, partners, and regulators are more likely to trust and adopt AI solutions that can be explained and audited. Conversely, opacity can lead to lost business, regulatory fines, and reputational damage.
“If a model’s decision-making is opaque, users and affected individuals may lose trust in its outcomes. It’s hard to trust a credit AI’s lending decision or a medical AI’s treatment recommendation if you ‘don’t know how the model makes the decisions that it does.’”
— Ravi Narayanan, VP of Insights and Analytics, Nisum
The Cost of Opacity
The financial consequences of unexplainable AI are real and growing. In the financial sector, companies have faced damages exceeding $100million due to failures in management supervision of ML-based applications, often stemming from the inability to explain or justify ML decisions
. Regulatory fines for anti-money laundering compliance failures, many linked to opaque AI systems totalled $5 billion in 2022 alone.
“Trust without transparency is a direct threat to the bottomline."
Organisations that deploy black box AI can face backlash or financial loss if the AI behaves unexpectedly... Such cases show that without explainability, AI errors can escalate into major crises before they’re caught.

Real-World Examples: Companies Striking (or Missing) the Balance
- Stanford’s Interpretable Skin Cancer Detection Model: By using LIME (Local Interpretable Model-agnostic Explanations), researchers were able to provide clinicians with understandable reasons for each diagnosis, increasing trust and adoption.
- Global Banks: Many now use SHAP (SHapley Additive exPlanations) to explain credit risk assessments, satisfying both regulators and customers.
- Getty Images vs. Stability AI: Getty Images sued Stability AI, citing the inability to audit or explain how copyrighted images were used in model training as a core transparency issue.
Navigating the Trade-Offs: Strategies and Best Practices
Technical Approaches
- Model Selection: Use interpretable models (e.g., decision trees, linear models) where possible, especially in regulated domains. For complex tasks, combine black-box models with post-hoc explainability tools like SHAP or LIME
- Hybrid Models: Employ hybrid approaches such as Constrainable Neural Additive Models (CNAMs), which allow tuning the balance between interpretability and performance
- Regularisation and Constraints: Add constraints to complex models to encourage simpler, more interpretable solutions.
Governance and Risk Management
- Adopt Standards: Implement frameworks like the NIST AI Risk Management Framework and ISO/IEC 42001, which emphasise explainability, transparency, and accountability
- Continuous Monitoring: Regularly audit models for bias, fairness, and interpretability. Maintain detailed logs and audit trails to support traceability and regulatory reporting
- Human-in-the-Loop: Ensure human oversight for high-impact decisions, allowing for review and override when explanations are insufficient
“By far, the greatest danger of Artificial Intelligence is that people conclude too early that they understand it.”
— Eliezer Yudkowsky, Machine Intelligence Research Institute
The Road Ahead: Future Implications for Interpretable AI
Regulatory and Ethical Mandates
The future of AI is "glass box," not blackbox.Regulatory frameworks are moving toward making interpretability mandatory in many sectors, especially for high-risk applications
. This will require organisations to invest in model-agnostic, automated, and human-centric interpretability tools.
Technical Innovation
Expect a rise in model-agnostic interpretability tools, automated explanation systems, and hybrid models that balance accuracy and transparency. Unified assessment frameworks will help organisations evaluate interpretability across different models and use cases
Business and Societal Impact
Interpretability will become a catalyst for AI adoption, enabling organisations to explain models to non-experts, regulators, and end-users. It will also be a cornerstone of ethical AI, supporting fairness, accountability, and the detection of biases or errors in automated decision-making
.
“AI is a mirror, reflecting not only our intellect, but our values and fears.”
— Ravi Narayanan, VP of Insights and Analytics, Nisum
The ultimate goal is to move from black-box models to"glass-box" AI systems that are inherently transparent, robust, and trustworthy. This will require advances in both model design andInterpretability science, as well as a culture of accountability and continuous improvement
When Machine Learning Surpasses Human Insight: Will Interpretability Still Matter?
Historical Precedents
History shows that when a new technology delivers overwhelming performance benefits, organisations and individuals often accept reduced transparency or interpretability. For example, early industrial automation and IT systems were widely adopted for their productivity gains, even when their inner workings were poorly understood by most users. However, this acceptance often lasted only until a crisis or failure exposed the risks of opacity.
Current State: ML Performance vs. Human Performance
In many domains, ML already outperforms humans, such as image recognition, text classification, and certain types of medical diagnosis.ML systems are more consistent and scalable than humans, leading to higher reliability in repetitive or data-intensive tasks. However, humans still outperform ML in tasks requiring flexible reasoning, ethical judgment, and adaptation to novel situations.
High-Stakes Domains: The Ongoing Need forInterpretability
Despite ML’s growing superiority in many tasks, interpretability remains crucial in high-stakes domains (healthcare,criminal justice, finance, public policy). High-performing but unexplainable ML systems have been rejected in areas like criminal justice (e.g., COMPASrecidivismtool) and healthcare risk prediction, due to concerns about bias, fairness, and accountability even when these systems outperform human experts
Cynthia Rudin (2019), a leading expert in interpretable ML, argues:
"For high-stakes decisions, we need models that are interpretable, as black box models are not sufficiently trustworthy for these applications, even if they are more accurate."
Technical Advances: Bridging the Gap
Recent advances are narrowing the gap between performance and interpretability. Hybrid models, post-hoc explanation tools (like SHAPandLIME), and inherently interpretable architectures are making it possible to achieve both high accuracy and transparency, especially in structured data domains .
Expert Predictions
Experts predict that as ML systems become more powerful, the demand for interpretability will persist, especially in domains where decisions have significant ethical, legal, or societal implications
Regulatory frameworks are moving toward making interpretability mandatory in many sectors, and public trust will continue to hinge on the ability to explain and justify automated decisions
"Expert opinion is converging on the view that the future of ML will require a careful balance between performance and interpretability, with increasing emphasis on the latter due to regulatory, ethical, and societal pressures."
Future Scenarios
- If ML Becomes Universally Trusted: If ML systems become so reliable, robust, and universally trusted that their decisions are never questioned, interpretability could become less of a differentiator much like how we trust the laws of physics without needing to see every calculation.
- In Low-Stakes, High-Volume Applications: In domains where errors have minimal consequences, performance may outweigh the need for explanations.
- If Regulation and Public Expectations Shift: If society collectively decides that performance is all that matters, interpretability could recede in importance.
However, in high-stakes, regulated, or ethically sensitive domains, interpretability is likely to remain essential for the foreseeable future.
Conclusion
The tension between AI innovation, interpretability, and business value is not going away. The most successful AI companies will be those that can innovate rapidly, explain their models clearly, and align their business models with evolving expectations for trust and accountability. Interpretability is no longer just a technical challenge, it is a business imperative, a legal requirement, and a societal expectation.
“The real competitive advantage in any business is one word only, which is AI.”
— Mike Lynch
But as the world moves from black box to glass box AI, the true advantage will belong to those who can make their AI not just powerful, but understandable.
