Balancing the Scales: Efficiency Gains vs. Practitioner De-skilling

Executive Summary

This research investigates the critical tension between machine efficiency and human agency in modern healthcare. As AI transitions from a validation tool to an autonomous diagnostic system, we must address the risks of Automation Bias and the potential erosion of clinical expertise.

Technical Evolution & The "Black Box"

The shift from rule-based systems to Deep Learning and CNNs has created a significant trade-off:

Performance: Unprecedented accuracy in segmenting tumors and predicting disease from EHR data.
Interpretability: Modern models rely on high-dimensional parameters that lack semantic equivalents in medical textbooks, creating a "Black Box" that clinicians cannot easily audit.

Key Challenges

Automation Bias: The tendency for clinicians to blindly accept machine outputs, leading to "de-skilling" where diagnostic and reasoning skills degrade over time.
Generative Risks: LLMs like Med-PaLM introduce the risk of Hallucinations—clinically persuasive but factually incorrect diagnoses that require high levels of vigilance to detect.
Algorithmic Bias: Systems may amplify societal stereotypes or be trained on data (e.g., Western-centric) that does not generalize to global populations.

Proposed Solutions: Interaction Design

To mitigate de-skilling, this paper proposes the use of Cognitive Forcing Functions (CFFs):

Human-in-the-loop: AI withholds its diagnosis until the physician enters a preliminary hypothesis.
AI as Evaluator: Positioning the system as a collaborative reviewer rather than an "oracle" to keep the doctor cognitively active.
Trust Calibration: Implementing interfaces that encourage clinicians to question the AI during moments of high uncertainty.

Future Research

Future work must focus on empirical data regarding cognitive retention—measuring how a doctor's independent diagnostic accuracy changes after years of AI dependency.
