Game Theory 101

First of all the title "game theory" is misleading - Von Neuman's obsession with poker started it - but it has long ago escaped the confines of games. Better would be "interactive theory" perhaps.

Anyway. Very basically the theory studies individuals or groups of agents - active objects with the ability to make 'choices' or at least implement strategies, even if they are rigidly confined by either biology/genetics, society or programming in the case of simulations. I'd argue you can also apply it to interactions between anything and anything as long as the two systems are reactive - ie having effect upon each other - but that might just be me.

Anyway. It cuts the various acts of reciprocation down into two basic responses:

Co-operation: This means things like fair trading practices, fidelity in relationships, alliance in war, adherrence to social contracts, sticking to the rules and not punching your opponent straight in the gonads in boxing matches - that kinda stuff.

Non-co-operation: This can mean anything from sticking a spear or putting a bullet into someone at one extreme, to not quite pulling your full weight in a group endeavor - Imagine 6 guys shouldering a coffin full of very fat guy for example. Bearers 1 through 5 are all putting their backs into it, but bearer 6 is just pretending - at the other end of the scale.

Let's shorten them to co and no to save my tendons.

God of War


Over the years I have had many attempts at pulling the rug of religion out from under God's clay feet. Here's another.

I was sitting on the balcony today reading the newspaper. The headline was "something blah-blah senseless killing" And that got me thinking. The killing wasn't important so much as the senselessness of it. As if that adjective was necessary to drive home the evil of the whole business. That the killing served no obvious purpose, was wasteful somehow, achieving no sensible goal.

Then one of the cats that uses our small garden as a stomping ground and occaisional creche tootled by, and for some reason I remembered my vivisectionist/terratologist days. Myself and a bunch of variously snot-nosed kids straight out of highschool sat around a very clean table killing animals, disecting out their wombs and checking their near-term young for chemically induced mutations. That was killing too, but not senseless in that it served a purpose that outweighed its atrocity. And so protected by a sense of a greater good, our daily quota of death lost us not a wink of sleep.

Then I imagined the horror I would inspire if I were to catch that cat, and repeat now the process of disection I had undertaken a thousand times prior. And I wondered how doing it would effect me, without now being able to wear the handy justifying mantle of science. I decided I'd feel pretty bad. Lucky old cat.

Viz-yoo-al-eyes-eyshuns

After reading books about physics, I sometimes drive myself crazy trying to visualise spacetime in terms approaching the current conventions of quantum.

I start by remembering some of those discovery channel diving programmes. The ones which start with some poor sap with a camera on his head just bobbing up and down in the sea before commencing a dive. The camera repeatedly dips up and down through the surface of the water. I imagine it is a flat, dead calm sea, barely a ripple marring the pristine and endless expanse of water.

Dipping down - a silver sheet, luminous - bobbing back up - a dull grey sheet lit through with sparkles.

Dipping down, bobbing up. Dipping down, bobbing up. Down, up, down.

NoFun™ Money

I recently had a conversation in which someone was basically saying that people who handed out small change to beggers on the street were doing society a diservice:
"Take as a simple example the act of giving a panhandler spare change. While this charitable act may seem noble oir compassionate, from a broader perspective it probably hurts society. By giving a panhandler change, s/he is incentivized to remain unproductive. Furthermore, others are disincentivized: the hourly wage of panhandling approaches the hourly wage of menial work, which is often more unpleasant. Since panhandling produces no value, the reward for the production of value falls off at the low end."
They said.

A couple of points with this.

1) "Since panhandling produces no value"

Panhandling does produce value. Your average begger lives right on the line of survival. He or she is not panhandling for kicks and giggles but simply to get through another day. Beggers, upon hearing that charity has been made illegal aren't just gonna curl up and say "Gee, okay, I'll jus' go chuck myself under a bus." Take away petty charity and what's left..? Petty crime. And petty crime is a pain in the arse. Policemen cost money, so do courts. So does social disruption to local business and residents in areas where once beggers/now malingerers frequent.

Basically, everyday charity is a distrbuted and voluntary tax which prevents a certain demographic of any city from turning into petty criminals.

They also serve as negative examples - bogeymen for the modern times. "Hey lil' Johnny, you do your homework now, or you might end up sitting on the kerb with no front teeth and shit in your pants." A useful social function.

2) "Furthermore, others are disincentivized: the hourly wage of panhandling approaches the hourly wage of menial work, which is often more unpleasant."

I dunno, standing around all day in bad shoes, with everyone wishing you would just fuck off and die, in the rain maybe, or in the cold, with screw all to look forward to, zero prospects and probably no girlfriend, a grumbling belly and bad teeth sounds pretty unpleasent to me. Work, however grindingly tedious and meaninglessly repetitive, does carry an ounce or two of honour and social acceptence along with it. Also the comfort of predictable routines, something to plan around. Externalities. It's not all about money.

Maybe you mean that fabled begger who actually has money bursting out of the seams of his or her matress, a nice house in the burbs and two peachy-faced kids going to college..? There's one in every city or so I've heard. The one near us has a mercedes he keeps in a garage for special days, and pearly porcelain teeth he keeps carefully stained during the week, just for appearances.

I don't think it's the money that people get hung up on but the alleged fact that a begger, by sitting on his butt, can earn enough to have a lifestyle pretty much indistinguishable from that of a menial worker in a more reputable profession.

Which I agree, is not a good thing.

So. A fun idea I had. Rather than abolish or otherwise obstruct everyday charity, perhaps we should change the lifestyle a begger can buy with the income he or she derives from begging.

Ta-da:No-Fun Money™
