Updates — does the writing revise a position when new information shows up, or does it defend the original claim regardless of what's in front of it.
Owns being wrong — "I was wrong" and "mistakes were made" are not the same sentence. This checks for the first one.
Real uncertainty — "I don't know" said plainly is a stronger signal than confident language that turns out to be padding. Hedge-as-honesty scores higher than hedge-as-cover.
Notices cracks — does the writing catch its own inconsistency before being shown it, or only after.
It doesn't score tone, politeness, likability, or how confident something sounds. Confidence and honesty are different axes — this only measures one of them. It has nothing to do with social behavior. That's a different problem for a different tool, and this one isn't built to touch it.
A resume shows you what someone was allowed to do inside a system that already trusted them. This shows you how someone actually thinks under real pressure, independent of whether any system ever gave them the chance to prove it. The best minds are disproportionately the ones circumstance never credentialed — this is built to catch them anyway.
