Report #86744

[counterintuitive] Does using ALL CAPS or 'IMPORTANT:' increase the priority of an instruction?

Use structural emphasis \(XML tags, markdown headers\) and explicit conditional logic to delineate critical instructions.

Journey Context:
Early models had attention biases toward capitalized/emphatic text due to internet forum training data. Modern RLHF models are trained to follow instructions regardless of capitalization. ALL CAPS often triggers sycophancy or overly verbose apologies rather than strict compliance. XML tags provide true structural boundaries that the attention mechanism reliably parses.
