An argument for yes: I intend to act trustworthy on Manifold Markets.
An argument for no: I'm not sure you have the information to know that I am going to act trustworthy. I think some people might have concerns due to my comments here, where I give arguments for all sorts of eccentric positions? https://manifold.markets/IsaacKing/has-scott-alexander-ever-attempted
I'm not 100% sure what the trustworthy-ish badge is meant to communicate.
IIRC it allows you to resolve other's markets. I would say that I don't intend to resolve other's markets based on eccentric interpretations like the above. (Nor my own markets, for that matter - if I have an eccentric interpretation then I would want to encode that explicitly in the resolution criteria.) And I suppose even if I did do so, you could just change the resolution and take away the badge.
But beyond that I think the trustworthy-ish badge might communicate other things too? In which case I'm not 100% sure what it might communicate.
