## Persuasion Knob #7: Simplicity
**One-sentence formulation:**
*Simple ideas spread because they are easy to remember, repeat, and defend, not because they are complete or accurate.*
### Adams’ core observation
Scott Adams notes that **simplicity beats accuracy in persuasion**. The human brain prefers models that are easy to hold and easy to share, even if they omit critical details.
Simplicity does not persuade by depth.
It persuades by **compressibility**.
What can be easily summarized travels farther than what must be carefully explained.
### What simplicity actually is
Simplicity is reduction.
It:
- Collapses complexity into slogans
- Replaces tradeoffs with binaries
- Substitutes narratives for mechanisms
- Converts gradients into categories
This makes ideas portable.
An idea that fits on a bumper sticker will outperform one that requires a white paper.
### Why simplicity works
Complexity creates friction.
Under complexity:
- Attention drops
- Confidence erodes
- Repetition fails
- Social sharing stops
Simplicity removes friction and increases velocity.
Adams’ point is not that people are stupid—it’s that **attention is scarce**.
### The danger of oversimplification
Simplicity often disguises:
- Missing assumptions
- Hidden costs
- False dichotomies
- Misplaced causality
Because simple ideas feel clear, they create false confidence.
Once a simple explanation is adopted, more accurate explanations feel like excuses or obfuscation.
### Ethical ambiguity
Simplicity can be used to:
- Teach fundamentals
- Communicate across skill gaps
- Align large groups quickly
But it can also be used to:
- Replace understanding with slogans
- Polarize debates
- Shut down inquiry
- Justify force
Adams emphasizes that simplicity is not truth—it is **transmission efficiency**.
### Why recognizing simplicity matters
When an idea feels especially satisfying or obvious, it is worth asking:
- What was removed to make this so clean?
- What tradeoffs are being hidden?
- What complexity is being ignored?
Clarity is not completeness.
### Why this knob follows repetition
Repetition strengthens whatever is repeated.
Simplicity determines what *can* be repeated.
Only simple ideas survive saturation.
This is why complex truths are fragile in mass discourse.
### The compounding effect
Simplicity stacks aggressively with:
- Fear (simple threats)
- Contrast (simple choices)
- Novelty (simple surprises)
- Repetition (simple slogans)
Together, they explain why bad ideas often outcompete better ones.
The final persuasion knob completes the set by exploiting explanation itself.
