>If social norms indeed dictate that significant figures transmit confidence, might it be deceptive to report 31.5 instead of 30 in conversation about the dinosaur market?
Not if it’s your bid in a market, yes if someone asks you for your probability estimate. Your best point estimate is obviously your best point estimate, and suffers from rounding.

Why? If she has to offer someone a bet as to which side the coin lands on, she should probably offer even odds, but I can’t see any situation where she has to report her probability but isn’t able to report that this is based on nothing more than her prior.
pressing shift+delete while you have a specific suggestion highlighted removes it from the list of suggestions, but I think that might also be only a temporary solution (although easier to implement than navigating to a settings tab).
