I always imagine the model rolling its silicon eyes when it’s assigned a personality (“you are an expert growth hacker”) at the start of the prompt. Was that ever actually shown to be effective? Is it still?
At least in the beginning of spicy autocomplete, this sort of role-play did work pretty dramatically at aligning a conversation to a task, though I don't think anyone ever tested it versus somewhat less cringe priming. After that, cargo cults do what they do best.
I really wonder if phrasing it differently would make a difference. In good faith conversations, it just doesn't happen that someone tells someone else who that person is.
