Simplification Principles

Find the simplest explanation that accounts for all the facts. Among competing hypotheses, prefer the one with the fewest assumptions.

Core Pattern

Apply Occam's Razor by:

1. Identifying the problem or phenomenon to explain
2. Listing all possible explanations
3. Counting assumptions required for each explanation
4. Preferring the explanation with the fewest assumptions
5. Verifying the simple explanation actually explains everything

Key Innovation: Avoid overcomplicating problems. Simple explanations are more likely to be correct and more likely to be actionable.

When to Use

Use this principle when:

• Debugging complex issues
• Diagnosing problems
• Evaluating competing theories
• Designing solutions
• Analyzing user behavior

Recognition test: "Are there multiple explanations?" If yes, find the simplest one that fits all facts.

The Principle

"Entities should not be multiplied without necessity."

In simpler terms: The simplest explanation that fits all the facts is probably the right one.

Step-by-Step Process

Step 1: List all facts

**Known Facts:**
1. [Observable fact 1]
2. [Observable fact 2]
3. [Observable fact 3]

Step 2: Generate explanations

**Explanation A**: [Description]
Assumptions: [List assumptions]

**Explanation B**: [Description]
Assumptions: [List assumptions]

**Explanation C**: [Description]
Assumptions: [List assumptions]

Step 3: Count assumptions

• Fewer assumptions = more likely to be correct

Step 4: Verify the simple explanation

• Does it actually explain all the facts?
• Any contradictions or gaps?

Step 5: Choose the simplest sufficient explanation

Application Examples

Example 1: Debugging

Facts:

1. API returns 500 error
2. Error occurs only for requests with > 100 items
3. Error started after recent deployment
4. No other endpoints are affected

Explanations:

A) Complex conspiracy:

• Database was compromised
• Hacker is targeting large requests specifically
• Security team knows and hasn't told us Assumptions: 4 (very unlikely)

B) Configuration issue:

• Request size limit was lowered in recent deployment
• Large requests exceed new limit
• Error handler returns 500 for size limit Assumptions: 3 (possible)

C) Simple bug:

• Recent deployment added code that crashes on large arrays
• The bug is in the endpoint handler only
• No other endpoints have this code path Assumptions: 2 (most likely)

Winner: Explanation C - Simple bug in recent deployment

Action: Review recent code changes to the endpoint, look for array operations.

Example 2: User Behavior

Facts:

1. Users are abandoning checkout at payment step
2. Abandonment rate increased last week
3. No UI changes were made
4. Competitors haven't changed pricing

Explanations:

A) Market shift:

• Economy changed last week
• Users suddenly can't afford products
• This affects only checkout step Assumptions: 4 (unconvincing)

B) Technical issue:

• Payment provider had outage last week
• Some users experienced errors
• They're now hesitant to complete payment Assumptions: 3 (possible)

C) Simple change:

• Payment processing time increased last week
• Users think it's broken and leave
• Nothing else changed Assumptions: 2 (most likely)

Winner: Explanation C - Payment got slower

Action: Check payment provider logs for processing time changes.

Example 3: System Design

Problem: We need to send notifications to users

Explanations:

A) Build notification microservice with queue, workers, retry logic, multiple channels, templates, preferences, scheduling, analytics:

• Complex architecture
• Multiple systems to build and maintain
• Many moving parts Assumptions: Many (complexity for its own sake)

B) Use existing email service, add simple notification table:

• Single database table
• Simple cron job to send
• Email service handles delivery Assumptions: Few (sufficient for current needs)

Winner: Explanation B - Simple solution

Action: Start simple, add complexity only when needed.

Output Format

After analysis, produce structured output:

# Occam's Razor Analysis: [Problem]

## Known Facts

1. [Observable fact 1]
2. [Observable fact 2]
3. [Observable fact 3]

## Possible Explanations

### Explanation A: [Name]

**Description**: [What this explanation proposes]
**Assumptions** (count: N):

- [Assumption 1]
- [Assumption 2]
- [Assumption 3]

### Explanation B: [Name]

**Description**: [What this explanation proposes]
**Assumptions** (count: M):

- [Assumption 1]
- [Assumption 2]

### Explanation C: [Name]

**Description**: [What this explanation proposes]
**Assumptions** (count: P):

- [Assumption 1]

## Simplest Explanation

**[Winning explanation]** - [X assumptions]

**Why it's simplest**: [Fewest assumptions, most direct]

**Verification**:

- ✓ Explains fact 1
- ✓ Explains fact 2
- ✓ Explains fact 3

## Confidence

Recognition Questions

Before applying:

• "What are the observable facts?"
• "Am I distinguishing facts from assumptions?"

During analysis:

• "How many assumptions does this explanation require?"
• "Is there evidence for each assumption?"

After choosing:

• "Does this actually explain ALL the facts?"
• "Am I choosing simple because it's easy or because it's correct?"

Common Mistakes

❌ Wrong: Choosing the simplest explanation that doesn't actually explain everything ✅ Correct: Simplest explanation that accounts for ALL facts

❌ Wrong: Ignoring evidence to fit a simple explanation ✅ Correct: If evidence doesn't fit, explanation is wrong (no matter how simple)

❌ Wrong: Using Occam's Razor to avoid necessary complexity ✅ Correct: Some problems are inherently complex - don't oversimplify

❌ Wrong: Counting assumptions incorrectly (grouping many assumptions into one) ✅ Correct: Each independent assumption counts separately

When NOT to Use

Don't use this principle when:

• You have clear evidence of complex causes
• The simple explanation leaves important facts unexplained
• Time horizons are long (complex systems emerge over time)
• Human behavior is involved (often irrational, not simple)

Related Principles

Hanlon's Razor: Never attribute to malice what can be explained by stupidity (or error)

Hume's Razor: Explanation must be based on evidence, not speculation

Popper's Falsifiability: Explanations must be testable

Pareto Principle: 80% of effects come from 20% of causes (related simplicity)

"If you can't explain it simply, you don't understand it well enough." - Albert Einstein

Trust intelligence - Occam's Razor is a heuristic, not a law. Simple explanations are usually right, but not always. Verify before committing.
