Doing a prisoner’s dilemma game with my 9yo and 7yo, but with mini marshmallows
Both cooperate, +3 each.
If one defects, +5 for the defector, +0 for the other.
If they both defect, +1 each.
Their reasoning is hilarious

Explaining the game to 7yo,
Me: Ok, if you both do thumbs up, you each get 3 marshmallows.
Her: I love this game!
Me: But if you go up and he goes down, he gets 5 and you get zero.
Her: I hate this game

When hearing the game setup, they both wanted to:
- make sure the other knew the same rules
- know how many rounds we would play
- make sure the other knew the same rules
- know how many rounds we would play
9yo first round logic:
“I think she wants the 5, and will do thumbs down. And if you go thumbs down, nothing that bad can happen. It’s either 1 or 5. So I choose thumbs down.”
“I think she wants the 5, and will do thumbs down. And if you go thumbs down, nothing that bad can happen. It’s either 1 or 5. So I choose thumbs down.”
7yo first round logic:
“He’s nice, and he likes fair stuff. I think he will want where we both choose thumbs up. So I’ll choose down.”
“He’s nice, and he likes fair stuff. I think he will want where we both choose thumbs up. So I’ll choose down.”
They both defected, lolz. They hugged each other giggling after the first round. 9yo: “I love you but I hate you.”
They both defected a second round again. I let them talk after and they came up with an agreement to cooperate.
They invoked the butt promise! https://twitter.com/lisatomic5/status/1292156573528109056">https://twitter.com/lisatomic...

Haha my daughter scammed him anyway
Now he’s at +2, she’s at +7, but she also has to eat a tomato
I wonder if John Nash ever considered the effect of butt promises

They both defected one more round after:
9yo: “Now I know she’s always just going to choose down. Of course I choose down.”
7yo: “He thinks I’ll choose down! So now I have to choose down.”
We have reached an equilibrium!

Ok taking a break for a little bit and gonna let them talk about it again :)
I lost my insider status!
They came up with a plan in secret to “make it so we have an even amount of marshmallows”
“But it’s a 2-round plan”
He did thumbs down and she did up, then they both did up. This seems like a good point to end the game, tied at 11 each.
