What the statement committed to
Commitment density measures how much of the statement binds the committee to action rather than describing conditions. This meeting reads 13.7, little changed from 13.6 at the previous meeting.
How certain the statement sounded
Epistemic certainty measures how much certainty the language carries relative to doubt markers (certainty − 0.5×doubt, scaled). This meeting reads 51.9, little changed from 51.6 at the previous meeting. Higher means more certainty, not more hedging.
Commitment density and epistemic certainty across the trailing meetings. Commitment rises as the language binds the committee to action; certainty rises as certainty markers outweigh doubt markers. This meeting is highlighted.
