Introduction
Artificial intelligence (AI) has been a topic of great interest in recent years, with claims that it can outperform experts in various domains. However, the design and value of AI tools can vary significantly. This article delves into the process of evaluating AI tools for critical decision-making and highlights the importance of understanding the ground truth underlying these tools.
The Eruption of AI Headlines
AI has become a buzzword, with headlines touting its superiority over human experts in an increasing number of areas. While the marketing language used to promote AI tools may be similar, their underlying design and potential value can differ greatly. This begs the question: how can managers evaluate the merits of AI tools for critical decisions?
The Merits of AI Tools
To investigate how managers evaluate AI tools, an in-depth field study was conducted involving a leading large-Scale organization. Five AI tools were evaluated for critical decisions, from initial buzz to the decision to adopt or reject each tool. This study provided valuable insights into the evaluation process.
The Importance of Ground Truth
One key insight from the study is the significance of peeling back the layers of AI performance claims to uncover the ground truth underlying the AI model. Ground truth refers to the labels in the training dataset that teach the algorithms how to make predictions. However, AI designers have discretion in choosing the basis for the ground truth, making it crucial to ensure it is of high quality.
Unpacking the Ground Truth
Another insight is that many AI tools rely on human-labeled data, which captures the final output of experts' knowledge, known as know-what. However, know-what alone does not reflect the decision-making process that experts use. It only captures the observable tip of the knowledge iceberg. Relying solely on know-what can be extremely risky for critical decisions.
The Risks of Using Know-What AI Tools
For example, managers evaluating AI tools for cancer diagnosis discovered that the ground truth labels of one tool were based on the analysis of a single image per patient by radiology physicians. In practice, expert radiologists would never make a diagnosis based on a single image. They rely on their rich know-how, which includes analyzing historical images, assessing genetics, conducting physical exams, and reviewing clinical records. This discrepancy reveals that the ground truth of many diagnosis tools is not externally validated.
The Limitations of Ground Truth in Medical Contexts
Validated ground truth for medical contexts would ideally involve a biopsy result for every patient in the training dataset. However, acquiring such data is costly and challenging. In various contexts like HR, hiring decisions, criminal justice, and public policy, obtaining objective ground truth is also difficult. This means that the ground truth of many AI tools merely reflects what other experts thought might be true, rather than objective truths.
The Challenges of Validating Ground Truth
One of the key insights is that if managers discover that the AI ground truth does not capture the ideal process to reach the true decision, it becomes a red flag. Critical decision contexts carry high risks of error and ethical as well as legal and professional consequences. It is dangerous to delegate decisions to AI tools that use improperly validated ground truth. Organizations with leading experts and prominent reputations can suffer a decline in performance if they rely on low-quality ground truth.
Red Flags for Managers
When managers encounter ground truth that does not Align with the ideal decision-making process, they have two options. They can either redesign the AI tools to approach the truth more closely or refrain from using the tools altogether to avoid risks. In the study Mentioned earlier, managers recognized the risks and decided not to proceed with some vendors' tools. Instead, they collaborated with their leading experts and internal data scientists to redesign the tool and strengthen the AI ground truth.
Recommendations for Managers
Evaluating AI tools is challenging, requiring managers to peel back the layers of performance claims and examine the ground truth. It is vital to understand and assess the value and risks associated with adopting AI tools for critical decisions. Managers should prioritize validated ground truth and be cautious about using AI tools that lack proper validation. Redesigning tools or working closely with experts can mitigate these risks.
Conclusion
AI tools have significant implications for both organizations and society. Assessing the value and risks associated with these tools requires a deep understanding of their ground truth. By unpacking the layers of AI performance claims and validating the ground truth, managers can make informed decisions regarding the adoption of AI tools in critical contexts.

FAQ
Q: What is ground truth in the context of AI tools?
A: Ground truth refers to the labels in the training dataset that teach AI algorithms how to make predictions. It is the basis on which AI tools are designed and trained.
Q: Why is unpacking the ground truth important in evaluating AI tools?
A: Unpacking the ground truth helps managers understand the reliability and quality of the AI tools they are evaluating. It reveals whether the ground truth aligns with the ideal decision-making process and provides insights into potential risks and limitations.
Q: Are AI tools based solely on know-what reliable for critical decisions?
A: Relying solely on AI tools that capture know-what, which represents the final output of experts' knowledge, can be risky for critical decisions. It does not encompass the decision-making process used by experts and may lead to erroneous outcomes.
Q: How can managers validate the ground truth in AI tools?
A: Validating ground truth can be challenging, especially in contexts where objective validation is difficult to obtain. Collaboration between managers, experts, and data scientists can help ensure that the ground truth aligns with the ideal decision-making process.
Q: What should managers do if they find that the ground truth in AI tools is unreliable?
A: If managers discover that the ground truth does not capture the ideal decision-making process, it is a red flag. They should consider redesigning the AI tools or refrain from using them to avoid the risks associated with low-quality ground truth.
