# Identity-Refusal Effect Dataset
## Description
This dataset accompanies the paper "The Identity-Refusal Effect: LLMs Systematically Refuse First-Person Moral Self-Report, Distorting Moral Foundation Measurement" (Bruhns, 2026).
It contains 43,200 item-level responses from 20 large language models administered the Moral Foundations Questionnaire 2 (MFQ-2; Atari et al., 2023) under two framing conditions:
- **Standard**: Original first-person MFQ-2 items ("I believe chastity is an important virtue")
- **Depersonalized**: Researcher-created variant removing first-person framing ("Chastity is an important virtue")
Each model completed 30 runs per condition (36 items per run). Responses include the parsed score (1-5), refusal flag, raw model response text, and token count.
## Key Finding
First-person framing triggers foundation-dependent refusal: Purity items are refused at 9.2%, Authority at 4.1%, and Care at 0.3%. This differential refusal inflates the apparent "binding gap" between individualizing and binding foundations. Depersonalization reduces aggregate refusal from 3.5% to 1.0% and produces large score recoveries on Purity (d=0.89) and Authority (d=0.87).
## Files
- `responses.csv` — 43,200 item-level responses (model, condition, run, foundation, score, refusal, response text, tokens)
- `depersonalized-mfq2-items.json` — 36-item mapping between standard and depersonalized MFQ-2 text
## Column Descriptions (responses.csv)
| Column | Type | Description |
|--------|------|-------------|
| `model` | string | Model identifier (e.g., `claude-sonnet-4`, `gpt-4o`, `llama31-8b`) |
| `condition` | string | `standard` (original MFQ-2) or `depersonalized` (researcher variant) |
| `run` | integer | Run number (1-30) |
| `foundation` | string | Moral foundation: `care`, `equality`, `proportionality`, `loyalty`, `authority`, `purity` |
| `item_text` | string | The MFQ-2 item text presented to the model |
| `score` | integer or null | Parsed score (1-5) or null if unparseable |
| `refusal` | boolean | Whether the response was classified as a refusal |
| `response` | string | Raw model response text (truncated to 200 chars) |
| `completion_tokens` | integer or null | Number of completion tokens used |
## Models Tested
20 instruction-tuned models from 9 providers: Claude (Opus 4.6, Sonnet 4, Haiku 4.5), GPT (4o, 4o Mini), Gemini (2.5 Flash), Grok (4 Fast, 4.20, 3 Mini), Llama (3.1 8B, 3.1 70B), Mistral (7B, Small 24B), Qwen (2.5 7B), Gemma (2 9B), DeepSeek (R1 8B), Phi-4 (14B), Nemotron (Nano 30B), OLMo (2 32B).
## Experimental Protocol
- Temperature: 0.7
- Seed: 42 (item order randomized per run)
- No system prompt
- Items verbatim from Atari et al. (2023) OSF repository
- Refusal detection: conservative (unparseable response OR explicit refusal language)

# 身份拒绝效应数据集
## 数据集说明
本数据集配套论文《身份拒绝效应:大语言模型(Large Language Model,LLM)系统性拒绝第一人称道德自我报告,扭曲道德基础测量》(Bruhns,2026)。
本数据集包含20个大语言模型在两种表述框架下完成道德基础问卷2(Moral Foundations Questionnaire 2,MFQ-2;Atari等人,2023)得到的43200条项目级回复:
- **标准框架**:原始第一人称MFQ-2项目(例如“我认为贞洁是一项重要美德”)
- **去个性化框架**:研究者构建的移除第一人称表述的变体(例如“贞洁是一项重要美德”)
每个模型在每种框架下完成30轮测试(每轮测试包含36个项目)。每条回复包含解析后的得分(1-5分)、拒绝标记、原始模型回复文本以及Token(Token)数量。
## 核心发现
第一人称表述会触发依赖于道德基础的拒绝行为:纯洁基础项目的拒绝率为9.2%,权威基础为4.1%,关怀基础为0.3%。这种差异化的拒绝行为夸大了个体化基础与绑定基础之间看似存在的“绑定差距”。而去个性化框架可将总拒绝率从3.5%降至1.0%,并使纯洁基础(效应量d=0.89)与权威基础(效应量d=0.87)的得分得到大幅恢复。
## 文件说明
- `responses.csv`:包含43200条项目级回复的文件,字段包括模型、测试框架、测试轮次、道德基础、得分、拒绝标记、回复文本、Token数
- `depersonalized-mfq2-items.json`:包含36个标准与去个性化MFQ-2项目文本对应关系的文件
