Developer challenges RAG assumptions in cognitive bias detection project

A developer spent two months building a Retrieval-Augmented Generation (RAG) engine designed to detect cognitive biases. During this process, three core assumptions were challenged: that increased knowledge leads to better retrieval, that passing evaluations guarantees production readiness, and that more context always improves LLM output. AI

IMPACT Highlights practical challenges and limitations in applying RAG and LLMs for complex tasks like bias detection, suggesting areas for future improvement.

RANK_REASON The item describes the development of a specific tool (RAG engine) and the lessons learned during its creation, rather than a major industry release or research breakthrough.
