Jung's theory of universal archetypes — validated across cultures and applied to brand strategy by Mark and Pearson — identifies 12 recurring identity patterns that activate distinct emotional responses. Campbell's monomyth provides the narrative structure within which these archetypes operate. Applied as a practitioner methodology by McKinsey, Ipsos, and leading brand consultancies, archetype classification allows us to map every brand's core emotional trigger. We classify on intake against brand language, customer reviews, and top-performing organic content.

Audiences cast creators into archetypal roles based on the emotional register of their content. "You make me believe I can do this" — Hero. "You make me feel beautiful" — Lover. "I trust everything you recommend" — Sage. Brand and creator archetypes must be congruent or narratively compatible — Hero brand paired with Sage creator carries credible authority; Hero brand paired with Jester creator breaks the tonal signal. We score archetype compatibility before any match is presented.

Seligman et al. argue that human cognition is fundamentally oriented toward future simulation — that we are prospecting organisms constructing and evaluating possible selves as a core cognitive function. Extrapolating to consumer behavior, we hypothesize that buyers in identity-purchase categories are actively simulating a future self when evaluating creator content, and that creator-brand alignment with that simulated self-concept meaningfully increases purchase intention. Our brand intake asks: "Describe the life your customer is purchasing toward — not the product they are purchasing."

Damasio's research on VMPFC-damaged patients demonstrates that emotional states significantly influence and often precede deliberative decision-making — meaning affective signals interact with, rather than oppose, rational evaluation. Applied to creator marketing: a creator whose content produces an emotional register incongruent with the brand's category creates a misaligned affective signal that rational product evaluation cannot reliably overcome. Engagement rate measures attention — it does not measure affective alignment. We score for it.

Sirgy's self-congruity theory, published in the Journal of Consumer Research and replicated extensively, demonstrates that purchase intention is highest when a brand's perceived image is congruent with the consumer's self-concept. Escalas and Bettman extend this to reference groups: ideal self-congruity — the match between brand image and who the consumer aspires to become — drives the strongest purchase intention in aspirational categories. We score across all four self-congruity dimensions, weighted toward ideal self-congruity in wellness, beauty, and fashion.

Cialdini's identification principle — among the most replicated findings in social psychology — demonstrates that social proof is most powerful when the observer identifies with the source. When archetype congruence, prospective self alignment, affective register, and self-concept overlap are all high, the conditions for identification are maximally met. The audience does not merely process the recommendation — they experience the creator as a credible representative of the self they are purchasing toward. That psychological state is what our composite score is measuring.
