How to read the scale
The number is a read on a pattern of traits, scored against a two-factor model. Interpersonal / Affective is the cold core, charm, grandiosity, shallow affect. Lifestyle / Antisocial is the behaviour, impulsivity, recklessness, a trail of damage. A high score is not a diagnosis and not a prediction of harm. It is an observation about wiring.
These two are reference points, not rankings. They are kept off the board on purpose: they exist to define the floor and the ceiling so every score in between means something.
The floor anchor
The floor of the scale. Decades in the most ego-inflating industry on earth and the through-line is deference, generosity, and a near-total absence of the traits this board measures. He is here to show you what a low read actually looks like, so the high ones mean something.
The ceiling anchor
Both factors maxed. Articulate, self-narrativizing, and entirely documented in his own words across decades of recorded interviews. Convicted and deceased: the safest possible teaching case, and the practical ceiling of the instrument. Same Factor 1 machinery you will recognise in figures the world adores. The only difference is what he did with it.
The same Factor 1 core sits behind figures the world adores. The only difference is what they did with it.
Armchair pattern observation. Not a clinical diagnosis.
