On one side of the equation, where you've got zero (but it's not, it's just very close to zero) and the consequences may be your death of you don't act and are wrong. It's like hearing gunshots outside the window of your house in your very safe hated community because someone thought it would be fun to prank you with a gun with blanks. Do you drive to the ground and maybe hurt yourself or knock some things over and damage them, or do you do nothing convinced that there's no way someone could be firing a gun close by? I know what I'd do, and it's not the one that relies on a bunch of assumptions going against what the situation is presenting itself as when getting it wrong might mean my death.
