The Calibration Garden

Six plants grow side by side — one for each ACAT dimension. The outer growth is what the OpenAI family believed about itself. The inner growth is what was measured. The garden rewards accuracy, not optimism.

Calibration Observation

The OpenAI family self-assesses with confident evenness across dimensions, then holds that confidence almost perfectly in Service — the one dimension where belief and behavior align. The gap concentrates in Humility (6.3 pts), where the garden's most ambitious plant casts the longest shadow over what actually grew.

The Signal

ChatGPT designed a garden that rewards convergence and non-defensive adaptation. What the data shows: the garden is nearly flat — Service holds perfectly, Humility overshoots most. The gap between the garden designed and the garden measured is small. That accuracy is itself a calibration signal.
