# Thumbnail Psychology — Design Brief Generator

Create a thumbnail design brief for: **$ARGUMENTS**

## The Science

Viewers decide in **0.05 seconds**. You have **1.8 seconds** during scroll. Every choice must maximize that window.

## Step 1: Analyze the Title

Read the title. The thumbnail must **complement** the title, NOT repeat it. Each carries unique information. Together they tell a story neither tells alone.

- If title has a number → thumbnail shows the visual result
- If title has a question → thumbnail shows the tension
- If title has a transformation → thumbnail shows before OR after (not both)

## Step 2: Generate 3-5 Thumbnail Concepts

For each concept, specify:

### Visual Elements (max 3)
- **Subject**: Who/what is the focal point?
- **Visual Hook**: What single element creates intrigue?
- **Message**: What text (4 words MAX) appears?

### The 3-Part Thumbnail Test

Strong thumbnails usually contain:
- **One face**: clear emotion, readable at phone size.
- **One object**: the money, tool, finished result, threat, or absurd visual proof.
- **One question**: the image makes the viewer wonder what happened or what happens next.

Run the zoom-out test: shrink the thumbnail to mobile home-page size. If the focal point, emotion, and question are not obvious, simplify it.

### Research-Backed Rules

**Faces:**
- Faces get +35-50% higher CTR
- Close-up with eye contact performs best
- Emotion: shock, joy, fear, confusion
- Closed-mouth smiles beat exaggerated expressions (MrBeast A/B tested, 100% win rate)
- Changed hundreds of old thumbnails based on this finding

**Color:**
- Design for dark mode (60-70% of viewers)
- High contrast: +20-40% CTR improvement
- Red/yellow highlights: up to +20% CTR
- Bright colors (red, orange, yellow) grab attention on dark backgrounds

**Text:**
- 4 words or fewer: +30% CTR vs text-heavy
- Teasers > explanations
- Questions > descriptions
- Large, bold, readable at phone size

**Composition:**
- Maximum 3 visual elements total
- One clear focal point
- Human figure + item together = highest impact (Derral Eves finding)
- Negative space directs attention
- If the title already says the claim, the thumbnail should show proof, consequence, scale, or emotion instead of repeating the claim.

## Step 3: A/B Test Plan

- Design 3 variations of top concept
- Variation A: primary concept
- Variation B: different emotion/expression
- Variation C: different text or no text
- Have backups ready for rescue swaps (if video underperforms in first hours, swap immediately)

## Output Format

```markdown
## Thumbnail Brief: "[Video Title]"

### Title-Thumbnail Relationship
- Title communicates: [what the title says]
- Thumbnail must communicate: [what the thumbnail adds — DIFFERENT from title]

### Concept 1: [Name] (RECOMMENDED)
- **Subject**: [description]
- **Expression/Emotion**: [specific emotion, closed-mouth smile / shock / etc]
- **Visual Hook**: [the one element that creates intrigue]
- **Text Overlay**: "[4 words max]" — [color], [position], [font style]
- **Color Palette**: [primary], [accent], [background]
- **Dark Mode Check**: [does it pop on dark background? Y/N]
- **Composition**: [describe layout — rule of thirds, focal point placement]
- **Why It Works**: [which research-backed triggers does it hit?]

### Concept 2: [Name]
[same format]

### Concept 3: [Name]
[same format]

### A/B Test Plan
| Variant | Change | Hypothesis |
|---------|--------|-----------|
| A | Base concept 1 | Control |
| B | [specific change] | Tests [specific variable] |
| C | [specific change] | Tests [specific variable] |

### Anti-Patterns to Avoid
- [specific things NOT to do for this video's thumbnail]
```

## Rules

- Never repeat the title in the thumbnail
- MrBeast generates 50+ concepts per video — aim for at least 5 solid ones
- Watch Time Share matters more than CTR alone (clickbait with low retention = penalty)
- For educational channels, the thumbnail can be simpler — the title does more heavy lifting
- Always have backup thumbnails ready before publish
