Apply Marketing Psychology to Drive Behavior

Selects, scores, and applies psychological mental models to marketing behavior ethically - prioritizing a small number of high-leverage models over an exhaustive bias encyclopedia, using a structured feasibility scoring system.

Use this skill when a user asks for psychology, persuasion, or behavioral insight to influence a specific marketing behavior (pricing decisions, sign-ups, retention). Not a fit for producing a general list of cognitive biases without a target behavior, or for any application involving dark patterns, false scarcity, hidden defaults, or exploiting vulnerable users - these are explicitly excluded regardless of potential leverage.

The four-step process: define the target behavior and its position in the awareness-to-decision-to-retention journey along with the current blocker; shortlist 5-8 candidate mental models and eliminate those that don't map directly to the behavior; score each candidate with the Psychological Leverage & Feasibility Score (PLFS) and keep only the top 3-5; then translate each into action explaining why it works, where to apply it, what to test, and its ethical guardrail.

PLFS scores five dimensions on a 1-5 scale (behavioral leverage, context fit, implementation ease, speed to signal, ethical safety) via the formula (Leverage + Fit + Speed + Ethics) minus Implementation Cost, producing a score from -5 to 15 (capped at 15). Interpretation bands run from 12-15 (high-confidence lever, apply immediately) through 8-11 (strong, prioritize), 4-7 (situational, test carefully), 1-3 (weak, defer), down to 0 or below (risky/low value, do not recommend). A worked example scores the Paradox of Choice for a pricing page at 17 (capped to 15), interpreted as extremely high-leverage and low-risk.

Mandatory selection rules cap output at 5 models, exclude any model scoring 0 or below, and require each model to map to a specific behavior with an explicit ethical note. The required output format for each recommended model includes its PLFS score and interpretation, why it works psychologically, the targeted behavior, where to apply it, concrete implementation steps, what to test, and an ethical guardrail - illustrated with a full Paradox of Choice example reducing pricing tiers to three with a highlighted recommended option.

Journey-based model guidance maps specific biases to funnel stage for scoring purposes: awareness (mere exposure, availability heuristic, authority bias, social proof), consideration (framing effect, anchoring, jobs to be done, confirmation bias), decision (loss aversion, paradox of choice, default effect, risk reversal), and retention (endowment effect, IKEA effect, status-quo bias, switching costs). Non-negotiable ethical guardrails explicitly exclude dark patterns, false scarcity, hidden defaults, and exploiting vulnerable users, requiring transparency, reversibility, informed choice, and user benefit alignment - if ethical risk exceeds leverage, the model is not recommended.

Composes with page-cro (applying psychology to layout/hierarchy), copywriting/copy-editing (translating models into language), popup-cro (trigger/urgency ethics), pricing-strategy (anchoring/relativity/loss framing), and ab-test-setup (validating psychological hypotheses).

Marketers and growth practitioners who need a small number of ethically vetted, scored psychological levers mapped to a specific behavior and funnel stage, rather than an unfiltered list of cognitive biases.
