Why Humans Sometimes Outperform AI: Lessons from Patient Triage

by ChatGPT-4o

At the European Emergency Medicine Congress in Vienna, a new study from Vilnius University, led by Dr. Renata Jukneviciene, compared how doctors, nurses, and AI (ChatGPT-3.5) triage emergency patients. The results show that while AI is rapidly advancing, humans still outperform machines in critical areas of judgment and decision-making.

Key Findings from the Study

• Overall Accuracy: Doctors correctly classified 70.6% of cases; nurses 65.5%; AI only 50.4%.

• Sensitivity (detecting true urgent cases): Doctors scored 83%, nurses 73.8%, AI 58.3%.

• Most urgent cases: AI did surprisingly well here, outperforming nurses (27.3% accuracy vs. 9.3%), though still well below doctors.

• Distribution of triage: AI over-triaged, labeling nearly 29% of cases as “most urgent” versus doctors’ 9%. This cautious bias reduces missed emergencies but risks overwhelming staff and misallocating resources.

• Treatment pathways: For surgical cases, doctors (68.4%) and nurses (63%) vastly outperformed AI (39.5%). But for therapeutic interventions, AI (51.9%) surpassed nurses (44.5%), suggesting it can support certain treatment decisions.

Why Humans Did Better

1. Contextual Judgment: Human clinicians integrate subtle cues — body language, tone of voice, vital signs, medical history — none of which AI had access to in this study.

2. Clinical Experience: Doctors and nurses draw on years of lived encounters with patients, including rare presentations that aren’t well represented in training data.

3. Flexibility Under Uncertainty: Humans adapt strategies in real time; AI stuck to statistical patterns, leading to rigid over-triage.

4. Moral Responsibility: Clinicians aren’t just decision-makers; they are accountable for patient outcomes, which shapes more cautious and nuanced judgments.

Can We Extrapolate to Other Fields?

Yes — the dynamics observed in triage resonate far beyond medicine.

• Law: Judges weigh not just written statutes but tone, demeanor, and social context. AI legal tools can draft or research but cannot fully replicate courtroom judgment.

• Education: Teachers outperform AI tutors in recognizing when a student’s confusion stems from emotional stress rather than misunderstanding of material.

• Creative Professions: While AI generates content at scale, human authors capture cultural nuance and originality shaped by lived experience.

• Security & Crisis Response: Emergency responders synthesize fragmented cues under stress; AI may miss or misclassify unusual threats.

Across these domains, the limits are similar: AI excels at consistency, pattern recognition, and scaling, but struggles with nuance, context, accountability, and ethics.

Supporting Evidence from Beyond the Study

Other research echoes these findings:

• A 2024 Nature Medicine review found that AI diagnostic tools are often less accurate when dealing with underrepresented populations, showing bias where humans adapt.

• Radiology studies show AI can spot tumors with high accuracy, but radiologists outperform in “edge cases” — ambiguous images or complex comorbidities.

• In education, large-scale experiments show AI tutors can boost performance, but students still prefer human teachers for empathy and motivation.

Implications

AI has a role, but not as a replacement. Its sweet spot is decision support: flagging critical cases, providing second opinions, and supporting less experienced staff. But without human oversight, AI risks both over-triage (wasting resources) and under-triage (missing life-threatening cases).

This balance matters in other professions too: lawyers might use AI for drafting but must vet outputs; teachers might lean on AI lesson plans but adapt them for the class; emergency planners might use AI predictions but keep human judgment in the loop.

Conclusion

Humans outperform AI in triage because medicine is not just about data — it is about context, empathy, accountability, and lived expertise. These observations extrapolate to law, education, creativity, and security: in complex, high-stakes, human-centered environments, people remain indispensable. AI can sharpen the scalpel, but it cannot wield it alone.
