[research] LLM fails to answer questions that require reversing a relationship it learned during pre-training
Do not assume bidirectional knowledge. If a relationship is critical, retrieve or provide both directional statements in the context explicitly.
Journey Context:
Autoregressive models model token sequences sequentially. They memorize A -> B but fail on B -> A. This is a fundamental architectural limitation of standard Transformers, not just a data issue. You cannot prompt your way out of it easily; you must supply the reverse context to bridge the gap.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
