Light Vs Fruit Classification

Light vs. Fruit Classification

Distinguish between "experiments of light" (investigations that illuminate causes and build understanding) and "experiments of fruit" (investigations that produce useful results). Ensures understanding precedes application and prevents blind optimization.

When to Use

• User asks "Should we investigate or just try things?"
• Team is optimizing without understanding why things work
• Need to decide between research and development approaches
• Something works but nobody knows why
• Pattern of "random success" - hits that can't be repeated
• Request to "classify this investigation" or "what kind of experiment is this?"
• Evaluating an R&D portfolio or research agenda
• Determining whether to pursue understanding or results

Inputs

The Core Distinction

Experiments of Light (Lucifera)

Purpose: To illuminate causes, reveal mechanisms, and build understanding.

Characteristics:

• Asks "WHY does this work?" not "DOES this work?"
• Values negative results (they eliminate hypotheses)
• Seeks general principles, not just particular solutions
• May not produce immediately useful outcomes
• Creates knowledge that transfers to other problems

Examples:

• Investigating why a successful campaign worked (not just celebrating the success)
• Understanding the mechanism behind a drug effect (not just that it reduces symptoms)
• Studying why some customers churn to understand retention generally

Experiments of Fruit (Fructifera)

Purpose: To produce useful results, solve immediate problems, and create value.

Characteristics:

• Asks "DOES this work?" not "WHY does this work?"
• Values positive results (they provide solutions)
• Seeks working solutions, even without understanding
• Produces immediately applicable outcomes
• May not transfer to other contexts

Examples:

• A/B testing to find the best headline (without understanding why it works)
• Drug trial to determine efficacy (without mechanism understanding)
• Trying retention tactics to reduce churn (without understanding root cause)

Why Light Must Precede Fruit

Bacon's insight: Fruit without light is fragile.

The Maxim: "Those who seek fruit before light will have neither fruit nor light in the end."

Workflow

Phase 1: Describe the Investigation

What is being done? What question is being asked? What outcome is sought?

Phase 2: Apply the Light/Fruit Test

Light indicators (mark if present):

• Primary question is "why" or "how" (not "what" or "whether")
• Negative results would be valuable (eliminate hypotheses)
• Goal is transferable understanding
• Current outcome: building mental models
• Would publish findings even if they don't solve immediate problem

Fruit indicators (mark if present):

• Primary question is "what works" or "which is better"
• Only positive results matter
• Goal is solving this specific problem
• Current outcome: working solution
• Findings only matter if they produce immediate value

Phase 3: Assess Current Understanding

Phase 4: Evaluate the Risk

What happens if you pursue fruit without sufficient light?

Phase 5: Make Recommendation

Based on current understanding level and risks, recommend:

Step 1: Pursue light (understanding) before fruit

Step 2: Pursue both in parallel

Step 3: Pursue fruit (results) with current understanding

**If pursuing fruit without sufficient light:**

| Risk | Likelihood | Impact | Notes |
|------|-----------|--------|-------|

### Recommendation

**Path Forward:** [LIGHT FIRST / FRUIT FIRST / PARALLEL]

**Rationale:**
[Why this path is appropriate given the classification and risks]

**If Light First:**
- [What understanding is needed before pursuing results]
- [How to structure the investigation for illumination]
- [What would indicate sufficient understanding]

**If Fruit First:**
- [Why current understanding is sufficient]
- [What understanding gaps are acceptable]
- [How to capture learning while pursuing results]

**If Parallel:**
- [How to structure both tracks]
- [How findings from each inform the other]
- [Decision point for pivoting to single track]

*"Those who have handled sciences have been either men of experiment or men of dogmas. The men of experiment are like the ant, they only collect and use; the reasoners resemble spiders, who make cobwebs out of their own substance. But the bee takes a middle course: it gathers its material from the flowers of the garden and of the field, but transforms and digests it by a power of its own." - Francis Bacon*

Constraints

• Do not privilege light over fruit absolutely - both are necessary
• Acknowledge time and resource constraints that may force fruit-first approaches
• Recognize that some domains have more accumulated light than others
• Fruit experiments can accidentally produce light (unexpected findings)
• Light without eventual fruit is sterile - understanding must eventually serve use

Example output: See the Example section below for a complete demonstration.

Example

Input: "We're running A/B tests on our checkout flow. Conversion improved 15% but we don't know why."

Output:

Why this works:

This example demonstrates the key principles of the skill in action. The approach is effective because:

• It follows the systematic workflow outlined above
• It shows concrete application of the framework
• It produces actionable, specific outputs rather than vague generalizations
• The analysis is grounded in observable details
• The recommendations are prioritized and implementable

Alternative applications:

This same approach can be applied to:

• Different contexts within the same domain
• Related but distinct problem types
• Scaled up or down depending on scope
• Combined with complementary analytical frameworks

Light vs. Fruit Classification: Checkout A/B Testing

Investigation Summary

What is being done: A/B testing different checkout flow designs Question being asked: Which checkout flow produces higher conversion? Outcome sought: Higher conversion rate on checkout

Classification Assessment

Light Indicators Present:

• Why/how question - No, asking "which is better"
• Negative results valuable - No, only winning variants matter
• Transferable understanding sought - No, solving this specific flow
• Building mental models - No, optimizing metrics
• Would share findings regardless of outcome - Unlikely

Fruit Indicators Present:

• What works question - Yes, "which variant converts"
• Only positive results matter - Yes, seeking winning variant
• Solving specific problem - Yes, this checkout flow
• Working solution sought - Yes, higher conversion
• Findings only matter if immediately useful - Yes

Classification: FRUIT (pure)

Understanding Assessment

Current Understanding Level: Empirical

Evidence:

• Know that variant B converts 15% better than A
• Do NOT know why (mechanism unclear)
• No theory of what makes checkout flows convert
• Previous tests also found winners without understanding

Risk Analysis

If continuing fruit without gaining light:

Recommendation

Path Forward: LIGHT FIRST (then return to fruit)

Rationale: Current approach produces wins but no understanding. The 15% improvement is real but fragile - you cannot explain it, repeat it intentionally, or transfer the learning. Before more A/B testing, invest in understanding WHY variant B works.

Specific Light-Seeking Actions:

1. User research: Interview customers who completed checkout with variant B. What did they notice? What almost made them abandon?

2. Session recordings: Watch actual checkout sessions. Where do users hesitate? What's different between A and B behavior?

3. Hypothesis formation: What theory explains why B works? Test that theory, not just variants.

4. Decomposition: Which specific element of variant B drives the effect? Isolate and test.

Success Criterion for Light: You have sufficient light when you can predict, before running the test, whether a new variant will improve conversion and explain WHY.

Then Return to Fruit: With understanding, future A/B tests become more targeted, learning compounds, and success becomes repeatable.

Integration

This skill is part of the Francis Bacon expert persona. Use it to ensure understanding precedes optimization. It pairs well with:

• tables-of-investigation for pursuing light when recommended
• idol-diagnosis for clearing obstacles before investigation
• anticipation-vs-interpretation for evaluating whether conclusions are properly grounded
