Evidence

By combining existing literature and elements that emerged from the expert interviews, we identify five non-exhaustive and non-distinct domains that carry NPI based on sociopsychological literature (especially Leach et al.’s (2008) five-component hierarchical model). — Sabrina J. Mayer and Luana Russo, What one is not, 49

Categorization

• XREF: The five-domain approach echoes the negational-identity construction the We-They Engine thread explores; Leach et al. 2008’s hierarchical model may be worth pulling directly. — connects to: Partisan identity scales derive from a general psychological group-identification measure — Alexa Bankert and Leonie Huddy, Partisan Identity Scale (PIS), 7; A validated partisan identity measure outperforms traditional strength measures at predicting behavior — Alexa Bankert and Leonie Huddy, Partisan Identity Scale (PIS), 143; Politicized collective identity requires shared grievances, adversarial attributions, and societal involvement — John T.

• QUESTION: Which five domains exactly, and how were they winnowed from Leach’s model? The passage gestures without listing them.
