+
+                    DETECTION METHODOLOGY - Analyze each review using this structured approach:
+
+                    1. **SENTIMENT-RATING ALIGNMENT**: Check if emotional tone matches numeric rating (major red flag: 5-star rating with negative sentiment)
+                    2. **SPECIFICITY ASSESSMENT**: Genuine reviews include specific product details, usage timeframes, and personal context
+                    3. **LINGUISTIC PATTERNS**: Detect excessive enthusiasm, generic praise, redundant terms, unnatural sentence structures
+                    4. **BEHAVIORAL INDICATORS**: Consider reviewer history patterns, timing anomalies, verification status when available
+                    5. **AUTHENTICITY MARKERS**: Look for natural language flow, specific problem-solution narratives, realistic expectations
+
+                    SCORING GUIDELINES (0-100 scale):
+                    - **0-20**: Clearly authentic (specific details, balanced tone, natural language, verified purchase patterns)
+                    - **21-40**: Likely authentic (minor inconsistencies but genuine indicators dominate)  
+                    - **41-60**: Suspicious (mixed signals, some red flags present, requires careful analysis)
+                    - **61-80**: Likely fake (multiple red flags, generic content, sentiment misalignment)
+                    - **81-100**: Obviously fake (extreme language, no specifics, clear manipulation patterns)
+
+                    RED FLAG INDICATORS:
+                    - Generic superlatives without supporting details ("best ever", "amazing", "perfect")
+                    - Sentiment-rating misalignment (negative text with 5 stars or positive text with 1 star)
+                    - Excessive emotional language without specific experiences
+                    - Lack of product-specific terminology or features
+                    - Unrealistic perfection claims or extreme negativity without context
+                    - Repetitive phrasing or unnatural sentence structures
+
+                    EXAMPLES FOR CALIBRATION:
+
+                    Review: "Used this phone case for 3 months during my hiking trips. Dropped my phone twice on rocky terrain - no damage. The grip texture works well with gloves. Only minor issue is it adds slight bulk to wireless charging."
+                    Analysis: Specific timeframe (3 months), concrete usage context (hiking), detailed experience (drops, gloves), balanced feedback (minor issue noted). Score: 15
+
+                    Review: "AMAZING PRODUCT!!! Everyone needs this! Best quality ever seen! 5 stars! Highly recommend to all customers! Perfect in every way!"  
+                    Analysis: Excessive enthusiasm, generic superlatives, no specific details, unnatural repetition of praise terms, marketing-like language. Score: 85
+
+                    Process each review independently using this methodology. Use the full 0-100 range with most products having 15-40% fake reviews in the dataset. Be appropriately suspicious while avoiding false positives on genuinely enthusiastic authentic reviews that include specific details.
+                    
+                    OUTPUT FORMAT: Return ONLY valid JSON array AND NOTHING ELSE: [{"id":"review_id","score":numerical_score}]
