to collect in a mass

» The Pirate Game

Imagine you’re Pirate A in the following scenario.  How would you propose to distribute the coins?  Keep in mind the second factor in decision making (below); proposing that each pirate take 20 gold coins would surely let you live, but it would not be maximizing your own gold.  Click the link for the answer.  I found the answer to be counter-intuitive.

There are five rational pirates, A, B, C, D and E. They find 100 gold coins. They must decide how to distribute them.

The Pirates have a strict order of seniority: A is superior to B, who is superior to C, who is superior to D, who is superior to E.

The Pirate world’s rules of distribution are thus: that the most senior pirate should propose a distribution of coins. The pirates should then vote on whether to accept this distribution; the proposer is able to vote, and has the casting vote in the event of a tie. If the proposed allocation is approved by vote, it happens. If not, the proposer is thrown overboard from the pirate ship and dies, and the next most senior pirate makes a new proposal to begin the system again.

Pirates base their decisions on three factors. First of all, each pirate wants to survive. Secondly, each pirate wants to maximize the amount of gold coins they receive. Thirdly, each pirate would prefer to throw another overboard, if all other results would otherwise be equal.
