Detect AI-generated survey responses using multiple heuristic and statistical methods. Based on academic research (Wu et al. 2025, Yang et al. 2024): - Linguistic analysis: perplexity scoring, burstiness, vocabulary diversity - Response pattern analysis: timing, straightlining, semantic similarity between responses - Statistical methods: response length distribution, lexical richness (TTR), coherence scores - Behavioral signals: completion time vs expected, copy-paste indicators, IP/device clustering
