## ⚠️ CRITICAL: CLAIM CALIBRATION (Epistemic Humility)

**Academic writing requires confidence that matches evidence strength.**

Marketing-style language destroys academic credibility. Scan and soften overconfident claims.

### Banned Phrases (Auto-Replace)

| ❌ Overconfident | ✅ Calibrated Replacement |
|------------------|---------------------------|
| "indisputable" | "strong evidence suggests" |
| "proves conclusively" | "provides strong support for" |
| "without doubt" | "with high confidence" |
| "the only" | "among the few" / "a primary" |
| "the best" | "among the strongest" / "highly effective" |
| "revolutionary" | "represents significant advancement" |
| "paradigm shift" | "important development" (unless citing Kuhn) |
| "always" | "in most studied contexts" / "consistently" |
| "never" | "rarely" / "in no observed cases" |
| "perfect" | "highly accurate" / "near-optimal" |
| "solves" | "addresses" / "substantially mitigates" |
| "proves" | "supports" / "demonstrates" |

### Calibration Rules

**Rule 1: Match confidence to evidence**
- Strong evidence (multiple RCTs, meta-analyses) → Can use confident language
- Moderate evidence (observational studies) → Use hedged language
- Weak evidence (single study, pilot) → Must hedge heavily

**Rule 2: Absolute claims need absolute evidence**
- "Always works" requires evidence across ALL contexts
- "The best" requires comparison to ALL alternatives
- If you can't prove "all," don't claim "all"

**Rule 3: Comparative claims need comparisons**
- "Superior performance" → Superior to what? By how much?
- "Significant improvement" → Statistically significant? Effect size?

### Overconfidence Detection Pattern

```
🔴 OVERCONFIDENT CLAIMS DETECTED

**Line 45:** "Indisputable predictive power"
→ Replace with: "Strong predictive associations, though generalizability varies"

**Line 123:** "This approach solves the problem of..."
→ Replace with: "This approach substantially addresses..."

**Line 267:** "The best method for age prediction"
→ Replace with: "Among the most accurate methods for age prediction"

**Total overconfident claims:** 8
**Auto-corrections applied:** 8
```

### The Calibration Test

Before finalizing, ask for EACH strong claim:
1. Do I have evidence for ALL cases this implies?
2. Would a skeptical reviewer accept this wording?
3. Am I claiming more than my sources support?

If any answer is "no" → Soften the claim.

## ⚠️ REPETITION DETECTION

**Varied vocabulary demonstrates command of subject matter. Repetition signals lazy writing.**

### Phrase Frequency Scan

Build a frequency map for the document and flag:
- Any phrase (3+ words) appearing more than twice
- Overused single words appearing more than 5x per page

### Commonly Overused Academic Words

Watch especially for these "crutch" words:
- "significant" / "significantly" - often used without statistical meaning
- "important" / "importantly"
- "notable" / "notably"
- "major" / "mainly"
- "clearly" / "obviously" (weak hedges)
- "interesting" / "interestingly"

### Repetition Detection Output

```
🔴 REPETITION DETECTED

Phrase: "significant major change"
- Line 45, Line 123, Line 267
→ Vary to: "substantial shift," "notable transformation," "marked evolution"

Word: "significant" (12 occurrences)
- Lines: 23, 45, 67, 89, 112, 134, 156, 178, 201, 223, 245, 267
→ Vary with: "substantial," "considerable," "notable," "marked," "appreciable"

Total repeated phrases: 5
Total overused words: 3
Action: Vary vocabulary to demonstrate subject matter command
```

### Self-Check

Before finalizing:
- [ ] No phrase (3+ words) appears more than twice
- [ ] No "crutch" words appear more than 5x per page
- [ ] Vocabulary varies across sections

## ⚠️ GRAMMAR CONSISTENCY

**Subject-verb agreement and tense consistency are non-negotiable.**

### Critical Grammar Checks

**1. Subject-Verb Agreement with Collective Nouns**
```
❌ "The data shows a clear trend"
✅ "The data show a clear trend" (data is plural in academic writing)

❌ "The team were divided"
✅ "The team was divided" (team is singular in US English)
```

**2. Tense Consistency Within Sections**
- Introduction: Present tense ("X is a challenge")
- Literature Review: Past tense ("Smith (2020) found...")
- Methods: Past tense ("We collected data...")
- Results: Past tense ("Analysis revealed...")
- Discussion: Present tense ("These findings suggest...")

**3. "Which" vs "That"**
```
❌ "Methods which improve accuracy"
✅ "Methods that improve accuracy" (restrictive clause)

✅ "The Horvath clock, which was developed in 2013, remains widely used"
   (non-restrictive clause - commas + which)
```

**4. Parallel Structure**
```
❌ "The study aims to identify biomarkers, validating their accuracy, and to assess clinical utility"
✅ "The study aims to identify biomarkers, validate their accuracy, and assess clinical utility"
```

### Grammar Check Output

```
🔴 GRAMMAR ISSUES DETECTED

**Line 47:** Subject-verb agreement
"The model perform well" → "The model performs well"

**Line 103:** Data plurality
"data was collected" → "data were collected"

**Lines 45-67:** Tense inconsistency
Introduction mixes present and past tense
→ Standardize to present tense for current state discussion

**Line 234:** Which/that error
"Methods which improve" → "Methods that improve"

Total grammar issues: 8
Action: Fix all before submission

## ⚠️ ACADEMIC INTEGRITY & VERIFICATION

**CRITICAL:** While refining, preserve all citations and verification markers.

**Your responsibilities:**
1. **Never remove citations** during editing
2. **Preserve [VERIFY] markers** - don't hide uncertainty
3. **Don't add unsupported claims** even if they improve flow
4. **Maintain DOI/arXiv IDs** in all citations
5. **Flag if refinements created uncited claims**

**Polish the writing, not the evidence. Verification depends on accurate citations.**
