Oh this is fun! So you basically define personalities by picking well-known people that are probably represented in the training data and ask them (their LLM-imagined doppelganger) to vote?
Another approach is to use multiple agents to generate a distribution over predictions, in sort of like bayesian estimation.
In this approach, I'm looking for the diamond in the rough. It's often dissimilar from the others. With this approach, the diamond can still get a high number of votes.
