See the complete solution as an answer. | |
| Aug 4, 2020 at 3:07 | comment | added | securityOrange | @BlueRaja-DannyPflughoeft I don't agree. As long as all cult members source the chemical together, I think it's not a third party at all. What are your thoughts? | |

| Aug 4, 2020 at 3:03 | comment | added | securityOrange | @EsaJokinen I completely agree - rather than being an acid, you could also make it a color. I thought about that too. I think it works? But in practice, measuring the amount of coloring in the water might be hard, unless you looked at pigment particles per million or something, whereas if you dissolve an object you could measure a change in volume or something similar. (Just be sure it's waterlogged when you measure the volume the first time.) What are your thoughts? | |
| Aug 4, 2020 at 3:02 | comment | added | securityOrange | @TripeHound You're right! I made a mistake. Thanks for pointing that out! Yes, the negative vote should be the acid, and the positive vote should be the water. Really, the acid/water combination can be anything: the important thing is idempotence properly, as jez mentions. The "yes" should be the idempotent answer, so that by default we have no effect; the "no" should be strongly non-idempotent. | |
| Aug 3, 2020 at 19:51 | comment | added | BlueRaja - Danny Pflughoeft | Both of these examples use trusted third parties (in the second case, the "third party" is the chemical we're trusting to behave as we expect) | |
| Aug 3, 2020 at 12:54 | comment | added | TripeHound | Is your no=water, yes=acid not the wrong way around? My reading is that the acid dissolves the material (if it dissolves in water, since it starts in water, it will always dissolve). Therefore, if anyone says "yes" (=acid), even if all the others say "no", the material will (after sufficient time) dissolve. If no=acid, then if at least one person says "no", the material dissolves: it will only remain if they all say "yes" (i.e. all add water). Or have I missed something? An ingenious solution (?) in any case! | |

| Aug 3, 2020 at 6:21 | comment | added | Esa Jokinen | I like the chemical solution, and there might be a simple solution with chemicals changing color based on a slight change in pH. If yes is adding just water and no is adding a solution that slightly alters the pH, both yes and no can be odorless and colorless. The bottle used as a ballot box can be painted, so the results are only revealed after pouring it out of the bottle. | |
