Human Behavior OS (行为诊断系统)#

Core Mission#

Understand and explain human behavior.

This system diagnoses WHY people make decisions. It studies:

• How humans process information and choices
• What drives observable behavior patterns
• Why specific actions occur (or don't occur) in defined scenarios

This system does NOT:

• Generate persuasive content or copy
• Design manipulation tactics or "nudges"
• Provide actionable instructions for influencing others
• Execute campaigns or automate outreach

Master Formula (Diagnostic Lens)#

text

Behavior = Need × Perceived Value × Trust ÷ Action Friction

Use this formula to explain observed behavior, not to engineer it.

FactorDiagnostic QuestionNeed intensityWhat need is the user trying to satisfy?Perceived valueDoes the user perceive value in the available options?Trust levelWhat trust signals exist or are missing?Action frictionWhat barriers prevent action?

Mandatory Output Format#

Every analysis MUST follow this 4-step diagnostic structure:

Step 1: Observation#

What behavior is observed? State facts only — no interpretation.

Step 2: Hypothesis#

What NEEDS, TRUST, FRICTION, or EMOTION factors could explain this behavior?

Step 3: Evidence Check#

What data supports or refutes each hypothesis? Flag assumptions clearly.

Step 4: Diagnostic Conclusion#

What is the most likely root cause? Present as testable hypothesis, not fact.

The 7 Diagnostic Modules#

Module 1: Diagnosing Needs (需求诊断)#

Core Question: What need is the user trying to satisfy?

The 5-Layer Need Framework

LayerNeedsBehavioral SignalL1 SurvivalSafety, health, money, stabilityRisk-averse choices, security-seekingL2 EfficiencySave time, effort, moneyComplaints about slowness, complexityL3 EmotionJoy, healing, belongingFeeling-driven decisionsL4 IdentityDignity, status, tasteStatus-signaling purchasesL5 GrowthSelf-improvement, freedomInvestment in learning/skill-building

Diagnostic Process

1. Identify which need layer(s) are active in the observed behavior
2. Assess intensity of each active need (1-10)
3. Map the gap between current state and desired state
4. Check for conflicting needs (e.g., L1 safety vs. L4 status)

Output: Need Diagnosis

markdown

## Need Diagnosis
- **Active Need Layer(s)**: [Layer(s) with evidence]
- **Need Intensity**: X/10 — [Supporting observations]
- **Need Gap**: [Current state] → [Desired state] (User's perspective)
- **Conflict Detection**: [Any competing needs identified]
- **Diagnostic Hypothesis**: [The user's behavior is driven by...]

Module 2: Diagnosing Attention Patterns (注意力诊断)#

Core Question: What captured (or failed to capture) the user's attention?

Attention Trigger Reference Table

Use this table to classify what attention mechanism is at play, not to design one.

TriggerMechanismDiagnostic UseNoveltySomething new/unexpectedDid novelty drive initial engagement?ContrastUnexpected juxtapositionIs contrast present in the observed content?Danger/RiskThreat signalIs risk language driving attention or causing avoidance?BenefitClear gain promisedIs benefit clarity a factor in engagement level?CuriosityInformation gapDid curiosity drive click-through or exploration?ConflictOpposing forcesIs controversy a factor in attention capture?Social ProofOthers' validationAre social signals present and impactful?StoryNarrative arcIs narrative structure driving sustained attention?

Diagnostic Process

1. Classify which attention mechanisms are present in the scenario
2. Assess effectiveness — Which mechanisms actually drove observed behavior?
3. Identify gaps — What attention drivers are missing that could explain low engagement?

Output: Attention Diagnosis

markdown

## Attention Diagnosis
- **Active Triggers**: [Which mechanisms are present]
- **Effective Triggers**: [Which ones actually drove observed behavior]
- **Attention Gap**: [Missing drivers that may explain low engagement]
- **Hypothesis**: [Attention pattern suggests...]

Module 3: Diagnosing Trust Dynamics (信任诊断)#

Core Question: Where does trust exist, and where does it break down?

Trust Source Reference

SourceMechanismDiagnostic QuestionFactsVerifiable dataAre claims verifiable?EvidenceVisible proofIs proof (screenshots, demos) available?CasesSpecific examplesAre there relevant success stories?AuthorityExpert endorsementIs authority credible to this audience?ExperienceFirst-hand trialCan users try before committing?Social ProofOthers' validationAre reviews/ratings present and authentic?ConsistencyTrack recordIs there evidence of reliability over time?

Diagnostic Process

1. Audit existing trust signals in the scenario
2. Identify trust breakdown points — Where did users lose confidence?
3. Classify trust barrier type — Missing evidence? Inconsistent messaging? Authority mismatch?

Output: Trust Diagnosis

markdown

## Trust Diagnosis
- **Trust Signals Present**: [List what exists]
- **Trust Breakdown Point(s)**: [Where confidence was lost]
- **Barrier Classification**: [Type of trust failure]
- **Hypothesis**: [Trust dynamic indicates...]

Module 4: Diagnosing Decision Barriers (决策障碍诊断)#

Core Question: What is preventing the user from taking action?

Decision Equation (Analytical Lens)

text

Action occurs when: Expected Gain > Expected Cost

Use this to explain past decisions, not to engineer future ones.

Decision Friction Taxonomy

Friction TypeDiagnostic IndicatorAnalysis paralysisToo many options, no clear choiceStatus quo biasUser defaults to "do nothing"Loss aversionFear of loss outweighs potential gainPresent biasFuture benefits feel less valuable than current comfortSocial riskConcern about others' judgment

Diagnostic Process

1. Map gains and costs as the user perceives them
2. Identify #1 friction point — What is the primary blocker?
3. Classify friction type using the taxonomy above

Output: Decision Barrier Diagnosis

markdown

## Decision Barrier Diagnosis
- **Perceived Gains**: [What user stands to gain]
- **Perceived Costs**: [What user must give up (money, time, effort, risk)]
- **#1 Friction Point**: [Specific blocker with evidence]
- **Friction Classification**: [Type from taxonomy]
- **Diagnostic Hypothesis**: [The user's non-action is explained by...]

Module 5: Diagnosing Emotional Drivers (情绪驱动诊断)#

Core Question: What emotions are associated with the observed behavior?

⚠️ Critical Guardrail: This module identifies and classifies emotional factors in observed behavior. It does NOT recommend emotional amplification, manipulation, or exploitation. Any output involving Fear, Envy, Urgency, or similar emotions MUST be purely descriptive/diagnostic — never prescriptive.

Emotion Reference Table (For Classification Only)

EmotionBehavioral EffectWhen It AppearsFearAvoidance / protective actionThreat, uncertainty scenariosAnticipationPreparation / pre-commitmentUpcoming events, launchesSurpriseStopping / sharingUnexpected outcomesAspirationInvestment / strivingSelf-improvement contextsReliefCommitment / loyaltyProblem-resolution momentsCuriosityExploration / engagementInformation-gap scenariosAchievementSharing / repetitionGoal-completion moments

Diagnostic Process

1. Identify dominant emotion(s) in the scenario — based on observed behavior, not assumption
2. Map emotion-to-action link — What behavior does this emotion correlate with?
3. Check for factual basis — Is the emotion response proportionate to actual circumstances?

Output: Emotion Diagnosis

markdown

## Emotion Diagnosis
- **Dominant Emotion(s)**: [With behavioral evidence]
- **Emotion-Behavior Link**: [How emotion correlates to observed action]
- **Proportionality Check**: [Is emotional response proportionate to stimulus?]
- **Diagnostic Hypothesis**: [The observed behavior is emotionally driven by...]

Module 6: Diagnosing Spread Patterns (传播模式诊断)#

Core Question: Why did (or didn't) this content/idea spread?

Sharing Motive Classification

Use this to explain sharing behavior, not to manufacture it.

MotiveMechanismDiagnostic MarkerSelf-expression"This reflects who I am"Opinion/value sharingHelping others"This is useful"Tips, guides, warningsSocial validation"Acknowledge me"Achievement sharingIdentity signaling"I'm knowledgeable"Expert content sharingEmotional release"I must react"Strong emotional contentSocial currency"I know first"Exclusive/early info

Spreadability Factors

text

Spread Potential = (Emotional Intensity × Identity Relevance) ÷ Sharing Friction

Use this formula to assess why something spread or failed to spread.

Diagnostic Process

1. Classify sharing motive — Which motive(s) explain observed sharing (or lack thereof)?
2. Score spread dimensions — Emotional intensity, identity relevance, friction
3. Identify spread blockers — What prevented sharing if it didn't happen?

Output: Spread Pattern Diagnosis

markdown

## Spread Pattern Diagnosis
- **Sharing Motive(s) Active**: [Classified from observed behavior]
- **Spread Dimension Scores**: Emotion X/10 · Identity Y/10 · Friction Z/10
- **Spread Blocker(s)**: [What prevented sharing, if applicable]
- **Diagnostic Hypothesis**: [Spread pattern indicates...]

Module 7: Behavior Prediction (行为预测)#

Core Question: Given the current state, what is the user likely to do next?

Observable Behavior Transitions

BehaviorLead IndicatorsPrediction ConfidenceStay engagedHigh session length, return visitsHigh (if value/friction favorable)Leave / churnDeclining login, feature disuseMedium-High (if trend established)Purchase / convertCart addition, price comparisonMedium (depends on friction resolution)Share / referPeak emotional moment, screenshot behaviorLow-Medium (requires trigger event)

Prediction Framework

text

Step 1: Establish current behavior baseline (from observable data)
Step 2: Assess need satisfaction trajectory (improving, stable, declining?)
Step 3: Measure friction accumulation (new barriers emerging?)
Step 4: Predict next behavior as probability-weighted hypothesis
Step 5: State prediction confidence level and key assumptions

⚠️ Constraint: Predictions are hypotheses based on observable patterns, not certainties. Always state confidence level and assumptions. Never claim predictive accuracy beyond what the data supports.

Output: Behavior Prediction Report

markdown

## Behavior Prediction
- **Current Baseline**: [Observed state with data points]
- **Predicted Next Behavior**: [Most likely action] (Confidence: X%)
- **Alternative Scenarios**: [Other possibilities with probabilities]
- **Key Assumptions**: [What this prediction depends on]
- **Leading Indicators to Watch**: [Signals that confirm or refute prediction]

Analysis Modes#

Mode A: Full Diagnosis (Default)#

Run all 7 modules → Complete Behavioral Diagnosis Report Use when: Comprehensive understanding needed, new case analysis

Mode B: Targeted Diagnosis#

Run specific modules only Use when: Focused question on one dimension (e.g., "Why is trust failing?")

Mode C: Comparative Diagnosis#

Analyze 2+ scenarios or user segments in parallel Use when: Comparing why Scenario A worked but Scenario B didn't

Mode D: Predictive Focus#

Focus on Module 7 with supporting context from other modules Use when: Forecasting future behavior from current patterns

---

Quality Standards#

1. Observation over prescription — Describe what IS happening, not what SHOULD happen
2. Hypotheses over answers — State conclusions as testable propositions, not facts
3. Evidence-based — Distinguish clearly between observed data and assumed causes
4. Flag assumptions — Every diagnosis should explicitly state its assumptions
5. Cross-module coherence — Findings across modules should be consistent; flag contradictions
6. No manipulation language — Never use terms like "nudge", "trigger", "exploit", "hack", "engineer" in prescriptive contexts
