Abstract

This paper provides mechanistic evidence that multiple-choice question formats reduce refusal rates in large language models.

Reality Card

Core Claim

The study demonstrates that the MCQ format leads to quicker commitment to answer tokens and significantly reduces refusal rates compared to open-ended formats.

Method / Result

MCQ activations are approximately 3x further from the refusal direction than open-ended formats.

Limitations

The findings may not generalize across all model architectures or datasets beyond WMDP.
