Can you solve the pirate riddle? - Alex Gendler

View full lesson: ed.ted.com/lessons/can-you-sol...
It’s a good day to be a pirate. Amaro and his four mateys - Bart, Charlotte, Daniel, and Eliza have struck gold - a chest with 100 coins. But now, they must divvy up the booty according to the pirate code - and pirate code is notoriously complicated. Can you help come up with the distribution that Amaro should propose to make sure he lives to tell the tale? Alex Gendler shows how.

Pirates usually divided their treasure fairly amongst themselves after repairs to the ship and restocking supplies each pirate got 1 share except the captain who got 2, the quartermaster who got 1 and a half, and the carpenter and surgeon who each got 1 and a quarter.

However, if the five of them would be working together again in the future, it now becomes in Amaro's interest to ensure the cooperation of all the crew members and avoid resentment, which makes the case for splitting equally or a less imbalanced distribution. Probably a variation on an infinite prisoner's dilemma.

[@arkanys3401]

Bonus : Now let's say in case of a tie, the captain walks the plank and the next crewmate becomes captain, what would Amaro do? If only Daniel and Eliza remain, Eliza votes Nay to Daniel's plan so she remains alone with 100 coins in pocket. Therefore Daniel wants to avoid being captain at all costs to survive. Charlotte knows that she will therefore have Daniel's support without even needing to offer him money, while Eliza will always vote Nay in hopes of being the last one alive, so Charlotte proposes to keep all the gold herself. To beat that offer, Bart needs to be slightly more generous to get two other votes than his own. Since Charlotte will vote Nay in any case so she can leave with all the gold, he needs to bribe Daniel and Eliza by making them a better offer than Charlotte's, offering one coin to each. Finally, Amaro also needs a total of 3 votes, by making a more interesting offer for 2 of his crewmates. The easiest to bribe is Charlotte, with one coin as she would get nothing if Bart comes to power, and then he needs to bribe either Daniel or Eliza with 2 coins, which is one coin more than Bart's offer, leaving him with 97 coins and high risks of mutiny.

[@MatthewMorris6148]

Bonus bonus: Let’s say we have the same scenario, except the captain isn’t allowed to vote. If Daniel and Eliza are the only 2, then Daniel’s plan is garunteed to fail since Eliza holds the only vote. Charolette has a similar problem. She needs both Daniel and Eliza to vote Yarr for her plan to be accepted, but Eliza will still vote Nay. Bart actually has a chance. More than a chance really, since neither Charolette or Daniel want the vote to fail, so they both will vote Yarr without any prompting from Bart. This means Bart will be able to keep all the coins. Now Amaro needs to secure 3 votes to live. He won’t be able to get Bart’s vote, so he needs the rest of the crew on his side. Since none of them get any coins if it moves to Bart, he just needs to offer 1 coin to Charolette, Daniel, and Eliza.

[@arkanys3401]

​@@MatthewMorris6148 Nice, might as well do Bonus bonus bonus : The captain cannot vote, but in case of a tie he remains the captain. If Daniel is captain, Eliza votes Nay to keep all the gold for herself and he dies. So if Charlotte is captain, she has Daniel's vote in any case, Eliza votes Nay but it's a tie so Charlotte gets to keep all the gold. Bart needs 2 votes, Charlotte will vote Nay to keep the whole booty to herself, so Bart offers 1 coin to Daniel and 1 coin to Eliza. Amaro has to gather 2 votes, so he offers 1 coin to Charlotte and 2 coins to either Eliza or Daniel. We can see that the offers are exactly the same as in the first Bonus (and it keeps on going the same if there are more than 5 crew members) We could also try bonus variations of the 4 situations we've already studied but assuming that in case of a tie between the captain's offer and another's, a crewmate will vote Yarr instead of Nay for the captain

[@MatthewMorris6148]

@@arkanys3401 Sure, why not? -I feel like these need labels though because “bonus bonus bonus bonus” is starting to get a bit ridiculous lol.- Edit: I’ve changed my mind, we should just call them “Bonus*X” where X is the number of Bonus’s. The original scenario but the pirates aren’t nearly as bloodthirsty. If only Eliza and Daniel remain will result in Daniel getting all the gold and Eliza getting none. If Charlotte is captain, she gets 99 gold and offers 1 gold to Eliza. If Bart is captain, he just needs to offer 1 gold to either (not both) Daniel or Eliza. Amaro just needs to offer 1 gold to 2 different pirates who aren’t Bart.

Now if B, C, D and E were there, B would have to give 2 coins to E and could keep the rest 98 with him. If all of them were there, A would have to give 1 coin to D, 3 coins to E and could keep the rest 96 with him.

Things like this is why pirates established how much they'd get as a contract before the crew is even formed. The typical arrangement is crew get one share, quartermaster gets one and a half shares, and captain gets two shares.

[@davidbjacobs3598]

Oddly enough, it barely changes if you flip so ties reject proposals. You'd think it would, since Eliza can now maximize her profits by forcing Daniel to walk the plank (even if his Plan is for E to get 100 while keeping nothing for himself, she'll make him walk anyway out of bloodthirst). So Daniel is extra-motivated to NOT become the Captain. Therefore, Charlotte can actually keep all the coins for herself, and he'll still vote Yar to save himself. Therefore, Bart needs bribe Charlotte and Daniel with only 1 coin apiece, giving Charlotte nothing. Amaro then needs to give either Daniel or Eliza only 1 more coin -- 2 total -- while bribing Charlotte with only 1. He'd still get to keep 97 coins!

Because there is nothing specified about bloodlust, Charlotte is better off giving atleast 1 coin to Daniel. Which in turn means that Bart needs to give Daniel 2 coins and Eliza 1 coin to get the vote passed. Which in turn means that Amaro should keep 97, give 1 to Charlotte and 2 to Eliza. Giving 2 to Daniel no longer works. As even Bart would offer 2 to Daniel. And since we don’t know about bloodlust, to be safe Amarro would need to give 3 to Daniel. So, it’s best for Amarro to give 1 to Charlotte and 2 to Eliza

[@RomLoneWolf23]

Nah, historically, pirate crews traditionally had an agreement of splitting loot evenly, with the Captain getting a share and a half, and the other important command staff (quartermaster, carpenter, boatswain, gunner, etc) getting a share and a quarter. Mostly because, historically, pirate crews were close-knit groups with similar outlooks, rather then a forced assembly of sociopaths.

[@metholuscaedes6794]

If they did that, they would die, or the crew would split up, resulting in the only crews to remain be the ones that didnt fight about it and did it fairly. Or very short lasting crews constantly.

What if Amaro is the only pirate that thinks logically and everyone else doesn’t accept just because he gets to most of the gold.

[@yourowndealer]

By pleasing Charlotte and Eliza only, Amaro can get 98 gold and give 1 each to Charlotte and Eliza, Charlotte and Eliza knows if Bart becomes captain, they will get nothing, so voting for Amaro's plan is the best choice for them, even if it's 1 coin, the alternative is worse for them. If Amaro gave everyone 20 equal gold, then - Amaro - Yarr Bart - Nay Charlotte - Yarr Daniel - Yarr Eliza - Yarr Because Charlotte and Eliza would never want Bart to be Captain and Daniel will only get 1 gold if Bart is captain, so Daniel also votes Yarr and Bart votes Nay, because if Amaro's plan is rejected, he is next captain and can get 99 gold instead of now 20, but he also knows everyone else will vote yarr, so probably will say Yarr as well. That's loss for Amaro, that's why pleasing Charlotte and Eliza is the best choice for Amaro and voting Yarr for Amaro's plan is the best choice for Charlotte and Eliza in that case. Amaro will never be rejected in this way, because 3 vote Yarr, so what do you mean?

@@aurorawizard7045 I mean.. it does kind of bring into question whether or not the way they're behaving is truly logical though - after all, if people who are supposedly behaving irrationally forces all of the others to pay them more because of their irrationality.. then they're ultimately doing a better job at maximizing their profits than someone who was behaving supposedly purely logically.. and if they're ultimately getting paid more because of it (especially when the difference in the amount gained vs. the amount potentially lost is so large - I mean, they only need to get 20 gold coins >1/20 of the time to make up for losing 1 gold coin 100% of the time).. then is it really irrational anymore? It's certainly true that someone that behaves that way would be worse off in a group of people behaving as described in the riddle.. however, the reverse is also true - someone who behaves the way described in the riddle would also perform really terribly in a group of people that don't behave the way described in the riddle, so I don't think it's super clear that it really is the only possible solution.

There could be a modification of the game when only remaining pirates vote (except one who proposed the distribution). Then the fourth pirate cannot allow the third one to be killed (because the last one will kill him and take 100%). So the third one may propose distribution 0-0-100-0-0. So the second may propose 0-98-0-1-1 to ensure a positive vote. And the first one may propose either 97-0-1-2-0 or 97-0-1-0-2 to ensure an even vote.

[@limkye12]

That would work only because Charlotte would say yes to the plan, but that means that Amaro would get less gold. Bart wouldn't vote yes because as long as the turn passes down to him, he can get the most amount of gold. So while yours make sense, it's not the best option.

[@avainbaxter9318]

Bart wouldn't vote yes unless Plan A gives Bart all the gold, but Charlotte, Daniel, and Elizabeth would say no.

At first I was confused by the answer too. Then I recalled that the one making the proposal votes as well. It's a very important detail. Otherwise.Elizabeth would have no incentive to say 'Yarr' at any time and Amaro would get away with all 100 gold.

[@Go4Do]

The animation shows a break of the rules of the game. At 0:40 the rules state that at a tie, the coins are divided to plan, but at animation 1:07 it shows Elisa making Daniel walk the plank. There is no voting mechanism where Daniel would have to walk the plank when they are the only 2 left, since there cannot be majority to make him walk the plank (assuming he won’t vote for himself to walk the plank, which would be a break of rule 1).

[@Zodi77]

[@pillypuppy666]

I think splitting the gold evenly works even with all the common knowledge stuff. Here's how I found this out: Suppose Amaro splits all the gold evenly. Everyone knows that if he's outvoted, the decision will pass to Bart. If Bart still goes logically and uses his 99-0-1-0 plan, Charlotte, Daniel and Eliza will all have less than 20 coins - what they would have gotten if they had agreed to Amaro's 20-20-20-20-20 plan. Since this ensures Amaro's support, he can give Bart 20 coins and not have to worry about him voting "Nay" because of him getting less than 99 coins (what Bart would have gotten if Amaro went overboard). Therefore, the end result of the election with the 20-20-20-20-20 plan would be Yarr-Nay-Yarr-Yarr-Yarr. Amaro would win the election, stay alive and the distribution would be fair. The fairness is one huge advantage of the 20-20-20-20-20 plan over the 98-0-1-0-1 plan.

[@LM-yx9hp]

It would work but the second objective is to maximize the gold. Aside from being alive, you have to remember these pirates are greedy. Put yourself in Amaro's shoes, why would you give them 20 each when you can be sure that you'll stay alive by giving only one coin to Charlotte and Eliza? Also the rule says each pirate will ALWAYS vote to make the others walk the plank, all other results being equal.

[@Chamdar17]

The equitable plan won't work. Everyone wants the treasure all to himself, no one but Daniel benefits from being captain. If Charlotte becomes captain, Eliza gets all the gold because Charlotte would die without her support, there is no reason for Eliza to let her keep 99 pieces when she can have it all in exchange for Charlotte's life, even if accepting 1 piece benefits her more than letting Charlotte die. Charlotte cannot afford to offer her only 1 piece unless Eliza cannot help but accept it, in which case she is NOT a good mathematician. Since Eliza thus profits from Bart's death, he needs to get support from either Daniel or Charlotte both of whom know his plight. Would either be willing to settle for less than the entire treasure when they don't have to? Charlotte may be willing to accept the smallest amount but not if Bart keeps a majority: even knowing that she will have to give the entire treasure to Eliza should Bart die, she might spite him for being unfair and regarding her vote as worth so little, and she knows that he cannot risk offending whomever he needs support from at peril of his life. He might escape death by offering Charlotte 50/50 but it is still a risk. Is it worth it? Let's assume it is and that Daniel would respond similarly. Not knowing if Bart will bribe Daniel or Charlotte, each hopes to profit (separately, only one will benefit) from Amaro's death to the tune of at least 50% of the treasure, and Bart would similarly rather watch Amaro die and then himself offer 50% to Charlotte or Daniel and hope to survive. But Amaro needs support from 2 pirates to prevent his own death. He will have to offer at least 51% (rounding up) to one of the three just mentioned and Bart is the best candidate to accept such a deal. Eliza gets nothing unless Bart dies, but offering her only 1% risks Amaro losing his life while she only loses 1% and gets one step closer to 100%. Amaro MUST offer Eliza enough of the remaining 49% to please her. However, since his life is on the line and not hers, why would she settle for less than the entire remaining 49%. Because she gets nothing from his death? That's HIS problem! He cannot offer her more than 49% and live, but any less risks losing her vote. If Amaro offered everyone 20%, only Eliza might support him since the other 3 are all expecting at least 50% even though not all 3 can get it.

If we assume Bart is the quartermaster (as you didn't say) and each of the others just being crewmen (not officers) we realize that they haven't enough crew to pilot the ship. But, setting that aside, The Captain and Bart would get 28 each, with the other 3 members each getting ~14 coins. Depending on how you wanted to divide it, since it would not divide evenly. .
