BenSyc: Benchmarking Conversational Sycophancy and Human Alignment in LLMs for Bengali Contexts

BenSyc is a culturally grounded benchmark for studying conversational sycophancy, social reinforcement, and alignment behavior in Bengali and Banglish online interactions.

The benchmark consists of manually validated Reddit post–comment pairs collected from Bengali-speaking online communities spanning Bangladesh and West Bengal. The dataset preserves naturally occurring Bengali, Banglish, English code-switching, emojis, slang, and informal social-media language to support realistic multilingual conversational evaluation.

BenSyc provides:- Binary conversational alignment labels- Fine-grained five-class conversational alignment annotations:  Invalidation, Neutral, Support, Validation, and Escalation- Human-validated rationales and evidence spans- Prompt templates used for evaluation- Evaluation scripts and benchmarking utilities

The benchmark was designed to evaluate how large language models respond to emotionally sensitive social conversations, including advice-seeking, interpersonal conflict, emotional support, and socially grounded reasoning.

The dataset supports:- Conversational sycophancy detection- Fine-grained conversational alignment classification- Response generation evaluation- Multilingual conversational safety research- Cultural alignment analysis for LLMs

To protect user privacy and support responsible research release practices, personally identifying metadata, usernames, URLs, timestamps, and Reddit identifiers were removed during preprocessing.
