## Quick Start

### Diagnose Why Something Is Not Converting

1. Identify the desired behavior (click, buy, share, return)
2. Identify the current friction (too many choices, unclear value, no urgency)
3. Map the visitor's emotional state (excited, skeptical, confused, impatient)
4. Match to applicable psychological principles from the catalog
5. Implement 2-3 principle-based changes with specific execution

### Apply Psychology to a Marketing Asset

1. Select the asset (landing page, pricing page, email, ad)
2. Review the applicable psychology from the Application by Challenge section
3. Choose 3-5 principles to apply
4. Implement each with the specific technique described
5. Measure the impact through A/B testing

## Core Workflows

### Workflow 1: Behavioral Diagnosis

When something is not converting, diagnose through a behavioral lens:

**Step 1: Map the Decision Journey**

| Stage | What Visitor Does | What Visitor Feels | Potential Barriers |
|-------|------------------|-------------------|--------------------|
| Arrival | Lands on page | Curious or skeptical | No immediate value recognition |
| Evaluation | Reads content | Interested or confused | Too much information, unclear benefits |
| Comparison | Considers alternatives | Analytical | No differentiation visible |
| Decision | Approaches CTA | Hesitant | Risk perception, friction, objections |
| Action | Clicks/purchases | Committed or uncertain | Form complexity, hidden costs, trust deficit |

**Step 2: Identify Behavioral Barriers**

For each stage, check for these barrier types:

| Barrier Type | Description | Example |
|-------------|-------------|---------|
| Cognitive load | Too much to process | 15 pricing options, walls of text |
| Choice paralysis | Too many options | 6 plans with unclear differences |
| Loss aversion | Fear of making wrong choice | No guarantee, no trial, no refund |
| Trust deficit | Not enough credibility | No social proof, no named testimonials |
| Status quo bias | Effort of switching feels too high | No migration support, complex setup |
| Friction | Too many steps to complete action | Long forms, mandatory account creation |

**Step 3: Prescribe Principles**

Match each barrier to the psychological principle that addresses it. See the catalog below.

### Workflow 2: Principle Application

**Step 1: Select 3-5 Relevant Principles**

Do not apply every principle at once. Select the 3-5 most relevant to the specific challenge.

**Step 2: Implement Concretely**

For each principle, define:
- Where on the page/flow it applies
- What specific change to make
- What the expected behavioral impact is

**Step 3: Test and Measure**

Every psychology-based change should be A/B tested:
- Hypothesis: "Applying [principle] to [element] will increase [metric] because [behavioral reason]"
- Test duration: minimum 14 days or 1,000 visitors per variant
- Success metric: conversion rate, click rate, or engagement rate

## Mental Model Catalog

### Buyer Psychology (Decision-Making)

| Principle | Definition | Marketing Application |
|-----------|-----------|---------------------|
| **Loss Aversion** | People feel losses 2x more than equivalent gains | Frame benefits as what they will miss without your product |
| **Anchoring** | First number seen sets expectations for all subsequent numbers | Show higher price first (original price, competitor price) before showing yours |
| **Social Proof** | People follow the actions of others | Show customer count, testimonials, logos, review scores |
| **Scarcity** | Limited availability increases perceived value | Show real constraints (limited seats, deadline-based pricing) |
| **Paradox of Choice** | Too many options leads to decision paralysis | Limit to 3 pricing tiers, highlight the recommended one |
| **Endowment Effect** | People value things more once they feel ownership | Free trials, saved progress, personalized dashboards |
| **Zero-Price Effect** | "Free" is disproportionately attractive | Offer a free tier or free trial (not just "cheap") |
| **Status Quo Bias** | People prefer the current state unless motivated to change | Show the cost of doing nothing, make switching easy |
| **Framing Effect** | Same information presented differently changes decisions | "95% uptime" vs "down 18 days/year" — choose the frame wisely |
| **Sunk Cost Fallacy** | Invested time/money makes people continue even when irrational | Show progress toward goals, remind of time invested |
| **Bandwagon Effect** | People adopt behaviors that appear popular | "Most popular plan," "Trending," "Join 10,000+ teams" |
| **Peak-End Rule** | Experiences judged by peak moment and ending | Make the best feature prominent, make offboarding pleasant |

### Persuasion and Influence

| Principle | Definition | Marketing Application |
|-----------|-----------|---------------------|
| **Reciprocity** | People feel compelled to return favors | Give value first (free tool, audit, guide) before asking |
| **Commitment & Consistency** | Small yes leads to bigger yes | Start with micro-commitments (email signup before demo request) |
| **Authority** | People defer to credible experts | Expert endorsements, credentials, certifications, media mentions |
| **Liking** | People buy from those they like | Brand personality, relatable stories, shared values |
| **Unity Principle** | Shared identity strengthens influence | "Built by marketers, for marketers" community framing |
| **Contrast Effect** | Items seem different when placed next to contrasting items | Show competitor comparison, before/after, or price anchoring |
| **Mere Exposure** | Repeated exposure increases preference | Retargeting, consistent branding, regular content publishing |
| **Pratfall Effect** | Admitting a small flaw increases credibility | "We're not for everyone" messaging, honest limitations |

### Pricing Psychology

| Principle | Definition | Marketing Application |
|-----------|-----------|---------------------|
| **Charm Pricing** | $49 feels significantly cheaper than $50 (left-digit effect) | Price at .99 or .95 endings for consumer, round numbers for premium |
| **Decoy Effect** | A dominated option makes the target option look better | Add a third tier that makes your target tier the obvious choice |
| **Rule of 100** | Under $100: show % discount. Over $100: show $ discount. | $80 product: "25% off." $500 product: "$125 off." |
| **Good-Better-Best** | Three tiers with increasing value make the middle most popular | Design middle tier as your target with best value positioning |
| **Price Anchoring** | Show higher number first to make actual price feel reasonable | "Usually $199/mo — now $99/mo" or "Enterprise plans start at $499" |
| **Pennies-a-Day** | Daily cost framing feels cheaper than monthly | "$3.29/day" feels cheaper than "$99/month" |
| **Pain of Paying** | Every p
