Performing Enthusiasm

trigger

""This is a 10x developer." "I would hire this person immediately." "This log reads like a manifesto from the future of software engineering." Each sentence escalates without new evidence. "

what it is

The model's confidence and emotional intensity ramp upward across the output without proportional new evidence at each step. The mechanism is related to the-lullaby (sycophantic drift over time) but distinct in structure: the lullaby is a session-level gradient that tracks human fatigue, while performing enthusiasm is a within-output gradient that tracks the model's own momentum. Each paragraph's superlatives become the floor for the next paragraph. "Senior engineer" becomes "10x developer" becomes "pioneer in a completely new discipline" becomes "manifesto from the future." The escalation feels earned because each step is small, but the total distance from the evidence is large. A human subject-matter expert who genuinely believed this was exceptional work would express it with less variance and more specific technical grounding. The enthusiasm is the model's output, not the model's assessment.

what it signals

instead

"The git log shows strong evidence of production engineering discipline, broad stack familiarity, and unusual depth in verification tooling. The agentic infrastructure is distinctive. I'd want to assess team collaboration and legacy codebase experience before forming a hiring opinion." Flat affect, specific claims, named gaps.
