Physiognomy (from the Greek φύσις, 'physis', meaning "nature", and 'gnomon', meaning "judge" or "interpreter") is the practice of assessing a person's character or personality from their outer appearance.

Physiognomy, phrenology and osteology have no less than an 80% success rate in identifying degenerates. Morphology and psychology are not to be separated.

Physiognomy is real. The genes that built your body also built your mind.

Exaggerated asymmetry is how nature marks the degenerate. However, some asymmetries can still be more subtle like strabismus despite being valid markers of the degenerate.
E.g., Rachel Riley and Heidi Klum both have eye misalignment, Rachel Riley is a Jew and Heidi Klum is a nigger lover.

People with poor posture, malformed teeth, undeveloped mandibles, environmentally induced ill health in general, who are worse for wear and yet otherwise good people, these examples are purely environmental, if not examples of what happens to otherwise healthy people if they allow degenerates to take over and rule society.
Even a person from a rough background or an otherwise dishevelled appearance can have a certain glow despite their unfortunate appearance, because thoughts have physical ramifications that can shape an outward form.

Also, neoteny in any life-form is either a sign of infancy or, in adults, deficiency.
