Will it work = do I guess it made the event better or worse afterwards?

Examples:
"Provide a larger pile of blankets, better"

"Provide a larger pile of blankets, worse"
"Give people name tags, worse"
"Give people labels on which to write a thing they are interested in re the future of AI, better"

"Make another prediction market about what to talk to people about and then adhere to its suggestions, worse"
"Try to start an argument about P(doom), better"

Last I checked it had ~34 RSVPs yes, and ~50 'interested'.

Betterness is in terms of something like the impartial good, not my own experience, relative to the counterfactual where I didn't do the thing. (Though that does include my own experience, so if a thing is too much effort to be worth it, that counts as worse.)

Things done to make it better have to be things I didn't do last time (e.g. 'buy pizza, better' won't be marked successful, because I did it last time).

If I can't tell if I did a thing, or whether it was good, I'll take my best guess. If a thing is an unfulfilled conditional, I will mark it unsuccessful though logically it is successful (e.g. "if there is a flying pig, try to catch it, better" will be marked unsuccessful).

I can't tell whether I'll be able to choose multiple correct answers, so if not, I'll choose the thing with the largest absolute effect on goodness (positive or negative). [ETA: seems like I can]
