After sending the previous message I started reading this (long) article: The No-Stats All-Star - NYTimes.com. Here's a key paragraph.
The five players on any basketball team are far more than the sum of their parts; the Rockets devote a lot of energy to untangling subtle interactions among the team's elements. To get at this they need something that basketball hasn't historically supplied: meaningful statistics. For most of its history basketball has measured not so much what is important as what is easy to measure — points, rebounds, assists, steals, blocked shots — and these measurements have warped perceptions of the game. ("Someone created the box score," Morey says, "and he should be shot.") How many points a player scores, for example, is no true indication of how much he has helped his team. Another example: if you want to know a player's value as a rebounder, you need to know not whether he got a rebound but the likelihood of the team getting the rebound when a missed shot enters that player's zone. That's a nice illustration of emergence. It may be subtle, but it's not magical or mysterious. To create the emergent level of abstraction that the paragraph refers to, the components have to work together in the right way.-- Russ ============================================================ FRIAM Applied Complexity Group listserv Meets Fridays 9a-11:30 at cafe at St. John's College lectures, archives, unsubscribe, maps at http://www.friam.org |
Russ,
For years, chicken breeders selected their chickens at the individual level, even though they were placing them in close quarters in crates of nine chickens. Chickens had to be debeaked and they were constantly pulling dead chickens out of the pens. . So, one day, a couple of poultry husbandry guys got a bright idea. They selected the best PENS of chickens for breeding. Pen rates of reproduction went up and the need for debeaking went away. If anybody is curious, I will chase down the reference.
I guess even a pen of chickens can be a black box.

Thanks Nick. I know (and love) the story. Here's my blog post about it. It shows that a pen of chickens is an entity.

Nick,
I don't think we have an issue. "No group genes" means that there are groups aren't biological entities in the sense that they have biological genes. Goups work because the genes of the individuals lead to effective group behavior. Those genes could be called group genes, but they are really genes in individuals. In fact, in social systems one could argue that there are group genes: constitutions, written down organizational structures, etc. -- Russ Abbott _____________________________________________ Professor, Computer Science California State University, Los Angeles o Check out my blog at http://russabbott.blogspot.com/ On Sun, Feb 15, 2009 at 7:51 PM, Nicholas Thompson <[hidden email]> wrote:

Russ,
I think I may disagree that there are no "group genes". Well, unless one defines gene in such a limited way that there are no genes at all. Please http://www.behavior.org/journals_BP/2000/thompson.pdf. I apologize for its size., which is stupid and unnecessary, and all my fault. The paper is not that big. I promise.
The mechanisms that produce inheritance are so far from validating the notion of an "atom of inheritance" that the fact that there are ANY traits that are passed reliably from generation to generation now seems to me a miracle. Please see THE PLAUSIBILITY OF LIFE by those two Harvard guys whose names i can never remember.

If you have never been to a chicken breeding facility, you should make it a point to do so. It will graphically illustrate for you a new depth in man's inhumanity to other living beings.

Some memes and social rituals can behave like group genes - for example the
ten commandments of the bible, or religions in general. They use groups as throw-away vehicles to lever themselves into the next generation. The founder of the Christian religion said "For where two or three are gathered together in My name, I am there in the midst of them" (Matthew 18:20), which means that the spirit of the group - whatever this is - comes only alive if the group is assembled. Randall Collins describes the sociological side of religion in his book "Sociological Insight: An Introduction to Non-Obvious Sociology". I miss this aspect in Dawkins book "The God Delusion". By the way, an interesting paper. It is remarkable that one of the most basic laws of nature - evolution by natural selection - is basically a metaphor. Darwin's "natural selection" is a metaphor, Dawkins' "selfish gene", too. -J. ----- Original Message ----- From: Nicholas Thompson To: [hidden email] Cc: [hidden email] Sent: Monday, February 16, 2009 5:21 AM Subject: Re: [FRIAM] Emergence: The No-Stats All-Star Russ, I think I may disagree that there are no "group genes".
