The passage around this formula

…or less capable consultant who struggles with professional business writing receives an immediate boost from an automated draft: $\text{Quality}_{\text{measured}} = w_1 \cdot \text{Fluency} + w_2 \cdot \text{Structure} + w_3 \cdot \text{Domain Validity}$ . When grading rubrics heavily weight surface fluency and coherence ( $w_1$ + $w_2$ $\gg$ $w_3$ ), low-skill participants appear to leap forward. However, this surface leveling introduces two profound systemic risks that short-term randomized controlled trials are structurally unequipped to measure:
