Challenges in Multiple Choice Evaluations

Multiple choice evaluations like MM LU and BBQ pose challenges in accurately measuring model performance. MM LU's widespread use can lead to cheating through question familiarity, formatting changes impacting scores, inconsistent implementation by labs, and errors in proofreading. BBQ, measuring social biases, requires significant engineering effort, with unique challenges in scale, implementation time, and defining bias scores. Both evaluations highlight the complexities and potential inaccuracies in assessing AI models.
