The trouble is there is a clear dichotomy in the scenarios where the LLM pushes back like this, most likely derived from RLHF. So anything health related, and "touchy" subjects in general will face this. But random design choices in your code, product roadmap debates etc do not elicit the same resistance.

Yes but you have to want that, and most people do not. Therein lies the rub.

This. I think it's the key.

I think there's a lot of alpha left in building a better and more intuitive UX for seed/top-p/temperature etc. The vast majority of users don't get that far.

Better prompting does provide more balanced responses to a certain extent but users looking for validation often subconsciously leave bread crumbs that the more powerful models pick up on.
