I feel like the problem with this dilemma is the fact that neither Gingerbread seems to consider the other's decision. a simple agreement to spare both now would result in significantly more benefit for both.
think of it this way: if the obvious, purely utilitarian option is to sacrifice, then clearly that is the option both will pick that option. however, if both people pick it, it is no longer the best option, as it results in far more limbs lost. both should know this, and thus the most rational option is for both Gingerbread to spare.
the only way the dilemma works with perfectly rational individuals is if both participants believe that the other ISN'T perfectly rational.

The reason people are having trouble grasping this is due to an error in the visuals (and the narration over the visuals. The fox says that if they both spare one another, they each lose one limb. And if they opt to sacrifice one another, they individually lose 3. However, the graph has these numbers reversed. The prisoner's dilemma predicts that, despite it being in their best interest to work together, each character will act selfishly because they worry the other one will do the same, and in doing so harm themselves. So, the best outcome does not always come from choosing to sacrifice, as the narrator wrongly states at 1: 52.

demonstrably yet ignores so many factors of human psychology, the relationship and feelings between the individuals, includes non-existent scenarios, has wizard capable of time travel, the idea of perfect rationality and that humans are rational which has demonstrably been tried and failed (Thatcher and Milton Friedman's economics. You can't apply mathematics to a fantasy and think it has anything to do with reality.

Video forgot to stipulate that they were necessarily selfish - if they truly cared about each other, they d add their numbers in each result together. Picking to spare always leads to a higher total score between them no matter what the other picks, and that s not even factoring in the added death that comes with keeping 0 limbs.
reply

I think there is a mistake? Initially we are told if they both choose spare at 0: 37, they each lose one limb. While both sacrificing means losing three limbs. But later in the chart at 1: 34 showing all the options, sacrificing each other is the one where they both lose one limb each and sparing loses 3? Am I just missing something?
reply

Does that means its now time for the east to sacrifice the west?
The inflation part was unnecessary.
Also at 0: 13 they could escape by changing the lanes, by moving apart one lane from the other.
Also by the looks, they look more like wool men than edible gingerbread men.

I wonder if this is taken into account when making decisions by our world leaders, then again I wonder how satisfied we would be if all decisions were made with this mathematical outlook. Very interesting
reply

So as long as people have a basic degree of reason and rationality we can all make little sacrifices and live comfortable and very prosperous lives looks at news yeah okay I knew it was too much to ask.

The wizard in this situation reminds me of god. This is why a country like India still maintains such a strong right wing progressive community with LGBT and women etc. thanks to Hinduism.
reply

eventually, the fox would stop eating them because who wants to eat the same food everyday for the rest of the future? the fox might as well get some diabetes or some sort of that lol
