We tested one of the most common prompting techniques: giving the AI a persona to make it more accurate

We found that telling the AI "you are a great physicist" doesn't make it significantly more accurate at answering physics questions, nor does "you are a lawyer" make it worse.

This doesn't mean that personas can't be useful - for example, they change how the AI answers questions, the format of output, and maybe other factors as well.

However, you aren't going to make the AI suddenly better through role-play.
