[counterintuitive] Using ALL CAPS or repeating 'IMPORTANT' to make the model prioritize an instruction

Use structural hierarchy \(XML tags, markdown headers\) and explicit conditional logic \(IF X THEN Y\) to enforce priority.

Journey Context:
Early models had attention mechanisms that somewhat responded to token frequency and capitalization anomalies. Modern instruction-tuned models are trained to follow system prompts and structural boundaries. Yelling at the model via ALL CAPS often leads to brittle behavior where the model over-optimizes for the yelled instruction while ignoring nuance, or it learns to ignore capitalization due to RLHF normalization. Structural isolation is mathematically more robust for attention.
