Contents. Life and career Forrester was born on a farm near, where 'his early interest in electricity was spurred, perhaps, by the fact that the ranch had none.
While in high school, he built a wind-driven, 12-volt electrical system using old car parts—it gave the ranch its first electric power.' Forrester received his Bachelor of Science in Electrical Engineering in 1939 from the, was inducted in 1949 into (ΗΚΝ) the Electrical & Computer Engineering Honor Society, and went on to graduate school at the, where he would spend his entire career. During the 1940s and early 50s, he did research in electrical and computer engineering, heading the, perfecting, and developing the 'multi-coordinate digital information storage device' (coincident-current system), the forerunner of today's. He is also believed to have created the first in the history of, a 'jumping ball' on an. In 1956, Forrester moved to the, where he was Germeshausen Professor Emeritus and Senior Lecturer. In 1961, arising from a project with, he wrote about the expanding effects down the due to fluctuations in demand, thenceforth known as the 'Forrester effect'.

In 1972, he received the, highest award. In 1982, he received the Computer Pioneer Award. In 1995, he was made a Fellow of the 'for his perfecting of core memory technology into a practical computer memory device; for fundamental contributions to early computer systems design and development'. In 2006, he was inducted into the Operational Research Hall of Fame. Forrester was the founder of, which deals with the simulation of interactions between objects in.
Industrial Dynamics was the first book Forrester wrote using system dynamics to analyze industrial business cycles. Several years later, interactions with former led Forrester to write Urban Dynamics, which sparked an ongoing debate on the feasibility of modeling broader social problems.

The urban dynamics model attracted the attention of urban planners around the world, eventually leading Forrester to meet a founder of the. He later met with the Club of Rome to discuss issues surrounding global sustainability; the book World Dynamics followed. World Dynamics took on modeling the complex interactions of the world, and, which was controversial (see also and ). It was the start of the field of.

Counterintuitive Behavior of Social Systems Counterintuitive Behavior of Social Systems is a 1971 paper by Jay Wright Forrester. In it, Forrester argues that the use of computerized system models to inform social policy is far superior to simple debate, both in generating insight into the root causes of problems and in understanding the likely effects of proposed solutions. Description Forrester characterizes normal debate and discussion as being dominated by inexact mental models: The mental model is fuzzy.
It is incomplete. It is imprecisely stated.
Furthermore, within one individual, a mental model changes with time and even during the flow of a single conversation. The human mind assembles a few relationships to fit the context of a discussion. As the subject shifts so does the model. When only a single topic is being discussed, each participant in a conversation employs a different mental model to interpret the subject. Fundamental assumptions differ but are never brought into the open. Goals are different and are left unstated. It is little wonder that compromise takes so long.
And it is not surprising that consensus leads to laws and programs that fail in their objectives or produce new difficulties greater than those that have been relieved. The paper summarizes the results of a previous study on the system dynamics governing economic dynamics in urban centers, which showed 'how industry, housing, and people interact with each other as a city grows and decays.' The study's findings, presented more fully in Forrester's 1969 book Urban Dynamics, suggest that the root cause of depressed economic conditions is a significant shortage of job opportunities relative to the population level, and that the most popular solutions proposed at the time (e.g. An increase in the amount of low-income housing available, or a reduction in real estate taxes) counter-intuitively serve to make the situation worse by increasing the population but not the availability of jobs, so that the relative shortage increases. The paper further suggests that measures to reduce the shortage - such as the conversion of land use from housing to industry, or an increase in real estate taxes to spur redevelopment of property - would counter-intuitively create the result desired when enacting the failed policies. The paper also gives an overview of Forrester's model of world dynamics that correlates population, food production, industrial development, pollution, availability of natural resources, and quality of life, as well as projections of those values into the future under various assumptions.
This model is presented more fully in Forrester's 1971 World Dynamics, and is notable primarily because it served as the initial basis for the model used by and in their popular 1972 book. See also. References. 2015-01-03 at the. On thocp.net, 2005.
