I think this is an area where induction is important?  If my previous interactions with someone are friendly conversation, it makes sense to interpret a request that they ask me questions as an invitation to more friendly conversation.  If they've previously interviewed me professionally and haven't had friendly conversations with me, it make sense to interpret that as an interview.

As to SBF's tweet, I think we should bear in mind that he sometimes lies.

Also,  even if the secret information that decision makers have isn't decisive there will still be a tendency for people with secret information to discount the opinions of people without access to that information.

I'm curious about when the FDA's expedited flu vaccine approval came to be.  It seems plausible to me that this is something grandfathered in from the early days and that the modern FDA wouldn't be flexible enough to start something like it.
