Answers to Selected Exercises

Selected exercises throughout the book have model answers or frameworks below. These are guides for self-assessment, not rigid correct answers — the quality of your own answer depends on your specific context and honest engagement with the question.

Part 1: Your Brain on Video

Chapter 1 (Attention)

Exercise: Identifying Bottom-Up vs. Top-Down Attention Triggers

Model framework for categorizing attention triggers in your own feed: - Bottom-up (involuntary): Movement, bright contrast against a dull background, sudden loud sounds, faces (especially expressive faces), unexpected visual changes, red or orange colors against neutral backgrounds - Top-down (voluntary): Content matching your existing interests, creator names you recognize, titles that reference something you already care about, thumbnails in genres you seek out

A useful test: Could this trigger capture your attention even if you weren't looking for it, or does it require your interest first?

Chapter 2 (Brain on Screens)

Exercise: Cognitive Load Audit

Signs of excessive cognitive load in your own content: - Viewers consistently drop off within the first 2 minutes (information density is too high too fast) - Comments frequently ask for clarification on the same points - Retention curve drops sharply after complex explanations - Viewers who finish the video report difficulty summarizing what they learned

Signs of appropriate cognitive load: - Steady retention curve with drops at natural pause points (chapter transitions, etc.) - Comments that engage with specific ideas rather than expressing confusion - High save rate (viewers want to return to the content — indicates it was valuable but dense enough to reward rewatching)

Chapter 5 (Curiosity Gap)

Exercise: Evaluating Your Own Titles for Curiosity Gap

Strong curiosity gap titles share: 1. An implied question that isn't answered in the title itself 2. Stakes — why does knowing this matter? 3. Specificity — "why I failed my science fair three times" > "why I failed"

Weak titles: 1. State the conclusion ("The Answer to Why X is Y") 2. Lack stakes ("A Discussion of X") 3. Are generic enough to apply to any creator ("My Update Video")

Test: Cover your title and describe what question it creates. If you can't generate a specific question with stakes, the title has no curiosity gap.

Part 2: How Things Go Viral

Chapter 7 (Viral Mechanics)

Exercise: Calculating Viral Coefficient

The viral coefficient (R₀) for a video: - Average shares per viewer: if a video with 10,000 views generates 500 shares - Each share reaches an average of 50 people (typical for personal networks) - Those 50 people have a 10% click rate - New viewers generated per share: 50 × 10% = 5 - R₀ = (500 shares × 5 new viewers) / 10,000 original viewers = 0.25

An R₀ of 0.25 means each viewer generates 0.25 additional viewers — the video is not spreading on its own, it requires initial push to reach scale.

For R₀ > 1: 10,000 views → 2,500 shares → 50 people each see the share → 10% click → 12,500 new viewers. Each subsequent generation produces 12,500 × 0.25 = 3,125 → still growing. This is the math of viral spread.

Exercise: STEPPS Analysis of Your Best-Shared Content

For content with unexpectedly high share rates: 1. Identify which STEPPS elements are present (Social currency, Triggers, Emotion, Public, Practical Value, Stories) 2. Most high-sharing content activates at least 2–3 simultaneously 3. The combination that most reliably drives sharing in each niche varies: - Educational content: Practical Value + Emotion (awe at a surprising fact) - Comedy: Emotion + Public (something relatable enough to tag someone in) - Commentary: Social Currency (makes the sharer look smart or in-the-know) + Emotion (outrage or admiration)

The most frequently absent element in low-sharing content: Social Currency — the sharer has no clear motivation to associate their identity with this content.

Part 3: Storytelling for Screens

Chapter 13 (Story Engine)

Exercise: Identifying the Three-Act Structure in Non-Fiction Video

Every compelling non-fiction video maps onto a three-act structure, even when the creator didn't deliberately plan it: - Act 1 (Setup): The world as it is, the problem or question, the character/creator's starting position - Act 2 (Confrontation): The investigation, the complications, the attempt to answer or solve, the discovery - Act 3 (Resolution): What was learned, what changed, what the viewer can take away

In an educational video: Act 1 = why this matters; Act 2 = the actual explanation with complications; Act 3 = the synthesis and takeaway.

Useful diagnostic: If you can't identify where Act 2 begins in your video, the narrative tension is probably missing.

Chapter 16 (Hook)

Model Hooks by Type

Question hook: "Why does every cell in your body have the same DNA, but your liver cells look completely different from your neurons?" — Works because: specific question with surprising premise; stakes are implied (something about biology is counterintuitive); immediately answerable in principle

Contrast hook: "Six months ago I had 300 subscribers. Today I have 180,000. Here's the only thing I did differently." — Works because: dramatic contrast that implies a learnable lesson; specific numbers increase credibility; "the only thing" creates curiosity about what the answer will be

In medias res hook: "I'm standing in the middle of a cornfield at 2 AM and none of this was supposed to happen." — Works because: raises three immediate questions (why cornfield? why 2 AM? what happened?); mystery + stakes + commitment to answer

Problem statement hook: "If you've ever spent three hours making a video and then posted it to 12 views, this is for you." — Works because: specific, relatable problem; direct acknowledgment of the viewer's pain; implicit promise of relevance

Part 4: Sight and Sound

Chapter 20 (Camera Basics)

Exercise: Minimum Viable Setup Assessment

The three camera qualities that actually matter for viewer experience: 1. Focus reliability: Does the camera stay focused on your face when you move slightly? (This matters more than sensor quality) 2. Low-light performance: Can you shoot in average indoor lighting without the image looking grainy? (This is the most common actual failure mode) 3. Audio input: Does the camera/phone allow an external microphone? (The biggest quality upgrade for most creators is audio, not video)

The qualities that rarely matter at the early stage: - 4K resolution (most viewers watch at 1080p; YouTube compresses anyway) - RAW video capability - Interchangeable lenses - Optical image stabilization (adequate with a tripod)

Test: Record 30 seconds of yourself talking with your current setup in your normal filming location. Watch it back. Is it comfortable to watch? Is the audio clear? If yes to both, your setup isn't the bottleneck.

Part 5: Content Genres

Chapter 25 (Comedy)

Exercise: Analyzing Your Comedy for Benign Violation

For each comedic element in your content, ask: 1. What is the violation? (Something wrong, unusual, or rule-breaking) 2. What makes it benign? (Why is this safe, harmless, or non-threatening) 3. Who bears the cost of the joke? (Yourself → safest; strangers/abstractions → neutral; specific people → highest ethical risk)

Content that generates hostility: violations that aren't experienced as benign by the audience (either too close to actual harm, or punching at people in the audience's own group).

Content that falls flat: violations that aren't actually violations (too expected, not surprising enough) or benign elements that remove all edge.

Part 6: The Creator's Strategy

Chapter 34 (Analytics)

Exercise: Reading the Retention Curve

Common retention curve patterns and their diagnoses:

Sharp drop at the beginning (first 15–30 seconds): Hook failure. The opening isn't establishing a sufficient reason to continue watching. Fix: redesign the hook.

Gradual, steady decline throughout: Normal — some viewers always leave. If the curve is too steep, pacing may be too slow or content too dense. Fix: tighten editing; increase pacing; remove sections that add length without value.

Cliff drop at a specific point mid-video: A specific element is causing viewers to leave. The drop usually follows a moment of confusion, irrelevance, or a topic change that loses the thread. Fix: identify the specific moment and remove or revise it.

Bump (retention increases briefly): Viewers are rewinding — this is a positive sign. Usually indicates something that needed rewatching (complex or rewarding content) or something unexpectedly engaging.

High completion but low shares/comments: The content is satisfying to finish but doesn't create urgency to spread. May indicate "good but not remarkable" content — worth watching but not worth talking about.

Chapter 35 (Thumbnails and Titles)

Exercise: CTR Diagnostic Framework

If CTR is below benchmark: 1. Does the thumbnail read clearly at thumbnail size (small, mobile-screen display)? If text is hard to read at 50px × 90px, redesign for simplicity. 2. Does the thumbnail convey an emotion immediately? Emotionally neutral thumbnails underperform. 3. Is the title creating a curiosity gap? Test by reading only the title — does it create a question you want answered? 4. Is there a disconnect between thumbnail and title? If they're not working together to promise the same thing, viewers experience cognitive dissonance. 5. Is this thumbnail distinguishable from your last 10 thumbnails? Repetitive packaging can develop viewer blindness.

If CTR is above benchmark but retention is below: — The thumbnail and title are overpromising. The content isn't delivering what the packaging implied. Fix: either adjust the packaging to more accurately represent the content, or adjust the content to deliver what the packaging promises.

Part 7: The Bigger Picture

Chapter 38 (Ethics)

Exercise: Personal Correction Protocol Design

A complete correction protocol should answer: 1. Within what timeframe will I correct? (Guideline: 72 hours for significant errors) 2. Where will the correction appear? (On-screen in the next video, not just a pinned comment) 3. What prominence is proportional to the error? (If 50K people saw the error, the correction needs comparable visibility) 4. What will I specifically say? (What was wrong; what the correct information is; how I'll prevent this) 5. Who will I credit? (The person who identified the error deserves acknowledgment if they consent) 6. What check did I skip that allowed this error? (Process improvement to prevent recurrence)

Chapter 39 (Monetization)

Exercise: Brand Deal Pricing Calculation

Full worked example:

Channel: Science education Average views per video: 65,000 Niche CPM benchmark: $35–$45 (educational/tech niche)

Integration pricing: - 60-second integration: 65,000 × ($40 / 1,000) = $2,600 - Dedicated video: $2,600 × 3 = $7,800 (typical multiplier for dedicated video)

Adjustments upward: - Engagement rate 4.2% vs. industry average 2.8%: +15% - Strong comment community (over 200 comments per video): +10% - Adjusted base: $2,600 × 1.25 = $3,250

Adjustments downward: - Brand requesting exclusivity: This is additional value to the brand; it should adjust price upward, not down. Push back if brand treats exclusivity as standard.

Final quoted range for 60-second integration: $2,800–$3,500

This is your starting point. Negotiation is expected. Know your floor.
