EvaluativeValence — Good/Bad/Neutral Classification of Gradable Predicates

@cite{nouwen-2024}

Distinct from scalar polarity (positive/negative scale direction):

• positive — denotes a good/desirable property (pleasant, nice, good)
• negative — denotes a bad/undesirable property (horrible, terrible, bad)
• neutral — no inherent evaluative content (usual, possible, tall)

@cite{nouwen-2024} argues that evaluative valence, not scalar polarity, determines the intensifier degree class (the Goldilocks effect): negative-evaluative bases yield H-degree intensifiers, positive- evaluative bases yield M-degree intensifiers.
