What is wrong with A.

Hi @ssquare, Happy to help! Answer choice (A) is incorrect because we do not learn anything about judges' consistency in instructing juries. We know that most judges employ only a "limited and primitive concept of jury inferential error," but this does not necessarily mean that they are inconsistent in their instructions. In fact, it is far more likely that these judges consistently fail to account for and minimize jury inferential error due to their lack of understanding of the research. Hope this helps! Please let us know if you have any further questions.

Thank you, Victoria!
