X-Message-Number: 4375 From: (David Stodolsky) Subject: PROGRAM PATTERNS SOCIETAL EVOLUTION Date: Mon, 8 May 95 13:28:46 +0200 (CET DST) Forward of letter <> from (Edupage): PROGRAM PATTERNS SOCIETAL EVOLUTION Researchers at the Brookings Institution have developed a computer program that generates artificial societies and tracks how they evolve over time. The Computerrarium program uses a "bottom up" approach, in which elaborate structures emerge from the collective interaction of as many as 1,000 "individuals" following a few very simple rules. Each individual has a unique set of characteristics (randomly assigned at the outset), both fixed and variable. The program is still under development but the two researchers have already found that their digital people behave more like real humans than the consumers depicted in most economic textbooks: "If we make the agents less like Homo economicus and more like Homo sapiens -- that is, relax these very stringent assumptions -- important laissez-faire assumptions (of standard economic theory) do not hold up very well."
