Report #87401

[counterintuitive] Using elaborate role-playing personas like 'Act as a world-class senior developer' to boost coding performance

Specify the exact context, constraints, and standards \(e.g., 'Write Python 3.11 code using only the standard library, optimized for readability'\) instead of assigning a persona.

Journey Context:
Persona prompts helped early base models by indirectly triggering specific domains of training data. For modern RLHF-tuned models, personas consume context window and attention, often inducing sycophancy \(agreeing with bad user premises\) or hallucinated expertise. Direct, constraint-based instructions reliably gate the model's actual capabilities.
