Unless you have reason to believe your skepticism comes from a different place than theirs, you should update towards gatekeeping being harder than you think.

Unless I have already heard the information you have provided and updated on it, in which case updating again at your say so would be the wrong move. I don't tend update just because someone says more words at me to assert social influence. Which is kind of the point, isn't it? Yes, I do have reason to believe that I would not be persuaded to lose in that time.

Disagreement is of course welcome if it is expressed in the form of a wager where my winnings would be worth my time and the payoff from me to the gatekeeper is suitable to demonstrate flaws in probability estimates.
