Physiognomy
What a stranger's brain concludes about your face in the first second — measured honestly, and bounded honestly.
With that said: first impressions are worth knowing about, because other people act on them whether or not they are correct. People form judgements of dominance and trustworthiness from a face in under 100 milliseconds, and those judgements are strikingly consistent between observers — which is what makes them measurable at all.
Physiognomy sits inside Appeal, weighted at roughly three-tenths of it. It reads in five blocks.
The five blocks
| Block | What it reads |
|---|---|
Dominance | The structural signals observers read as physical and social forcefulness — brow, jaw, midface, the relationships between them |
Valence | Warmth and approachability. The resting shape of the mouth and eye region does most of the work here |
Maturity | Where the face reads on the baby-faced to mature axis, which is largely proportion rather than age |
Impression quality | How coherently the above combine — whether the face sends one clear signal or several competing ones |
Penalties | Specific combinations that consistently cost an impression, applied as deductions rather than folded into the blocks above |
Why dominance is not simply maxed
High dominance is not a high score. Authority reads best in a band rather than at the extreme, and past that band it decays — a face can read as forceful in a way that costs it warmth without buying anything back.
This is the same shape as the Dimorphism caveat, and for the same underlying reason: the perception literature keeps finding optima rather than monotonic slopes, and a model that treats "more" as "better" is a model that has stopped describing people.
What moves it
Less than you would hope, and more than you would think.
The structural half is structural — the same interventions that move Dimorphism and Harmony. But a meaningful part of the valence read comes from the resting position of your mouth and eyes, and that is affected by things as mundane as sleep, jaw tension, and whether you are actually relaxed in the photograph.
Which is worth saying plainly: some of what this measures is your photograph's mood, not your face's structure.
