Deterministic Decisions for High-Stakes AI. A Zero-Egress Pipeline with the Deployability of RAG and the Accuracy of Machine Learning
arXiv:2606.29280v1 Announce Type: new Abstract: We identify intervention bias as a previously unquantified failure mode of zero-shot large-language-model (LLM) educational advisory agents: without task-specific training, they recommend action when a hindsight-optimal oracle policy mandates inaction. In a six-arm ablation on the Open University Learning Analytics Dataset (N=800 students, four temporal cutoffs), at day 56 -- when the oracle designates 70.1% of students as needing no intervention -- zero-shot GPT-4o recommends action for 73%, a 43 percentage-point false-positive rate.

The proliferation of LLMs into high-stakes decision-making sectors necessitates rigorous evaluation of their reliability and potential failure modes, which this research addresses directly.
This research highlights a critical failure mode in zero-shot LLM deployments for advisory roles, revealing a significant intervention bias that can lead to suboptimal or harmful outcomes.
The understanding of zero-shot LLM deployability in sensitive applications now includes a quantifiable 'intervention bias' that needs to be mitigated through task-specific training or alternative architectures.

- · Organizations implementing RAG-based systems
- · Companies relying solely on zero-shot LLM deployments
- · End-users of unvalidated AI advisory systems
Demand for specialized, task-specific training and fine-tuning of LLMs for high-stakes applications will increase.
Development of new AI architectures emphasizing explainability, determinism, and bias mitigation will accelerate.
Regulatory bodies may introduce stricter guidelines for AI systems in critical sectors, requiring demonstrable bias reduction and safety metrics.
