I have recently been annoyed by all of the twitter posts showing up on the main page of this blog, it makes it look like all this is for is digesting my tweets. These posts also show up as “notes” on my facebook page, which is unnecessary because each tweet updates my facebook status anyway. So, I have removed the “twitter” category from being displayed on the main page (if you reeeeally want to see all my weekly tweet digests, on the right side under “categories” you can select “twitter”) , and I have removed those twitter posts from the main feedburner RSS feed. (again, if you want to subscribe to the “full” feed, you can move your subscription to blog.aliencam.net/feed/ , but that’s a little weird, you could just follow me on twitter or something).
Anyway, today’s XKCD is another stroke of genius, analysing the ratios of google searches for games with their “strip” counterparts.

After getting over the initial hilarity of it all, I went through and actually read the list. Really, out of these games, the best options for a “strip” alternative (yes, including poker) I find to be Iterated Prisoner’s Dilemma, Chess, Tennis, and Poohsticks. That particular order is due to the high likelihood of being arrested for public indecency with the last two ( although if you have a private tennis court or bridge…), and I have chosen to disregard beer pong because it doesn’t really fit in with the rest of the list. Anyway, I realise the likelihood that many people have not heard of Prisoner’s Dilemma, so here is a quick description.
Prisoner’s Dilemma
This is an exercise/game used in game theory, psychology, and statistics, and is surprisingly fun to play. The situation is this: two criminal partners are being questioned (independently) by the police. The police offer each prisoner a deal if they co-operate and betray their partner. The rest is best explained by this consequence matrix (how long each prisoner goes to prison):
|
X Defects |
X Stays Silent |
| Y Defects |
5 years each |
x:10 years, y:0 years |
| Y Stays Silent |
x:0 years y:10 years |
No consequences |
In a game of “Iterated Prisoner’s Dillema”, multiple turns are played (hence the word “iterated”). A prisoner who stays silent is usually allowed to punish one who betrays the other after each turn.
The game is played by each player having two cards, one marked “defect” and the other “stay loyal”. Players each place one card face-down, then they are turned up at the same time. The optimal situation would be for each player to stay loyal to their partner, but if either defects, the other will have to deal with the large consequence. Because of this, if a player always defects, they will be “safer.”
If you don’t remember Poohsticks (shame), it was a game that Winnie the Pooh invented, all players drop sticks into the water off the side of a bridge, then run to the other side to see whose stick reaches the other side first. (I imagine this would be easiest if you tied a coloured string to each stick).
