Negative Differences

“We should always expect to see the process of achieving good fit between two entities as a negative process of neutralizing the incongruities, or forces, which cause misfit.”

Flimsy Solution Conviction

“In the case of a real design problem, even our conviction that there is such a thing as fit to be achieved is curiously flimsy and insubstantial. We are searching for some kind of harmony between two intangibles: a form which we have not yet designed, and a context which we cannot properly describe. The only reason we have for thinking that there must be some kind of fit to be achieved between them is that we can detect incongruities, or negative instances of it.”

Time for Equilibrium

“Misfit provides an incentive to change; good fit provides none. In theory the process is eventually bound to reach the equilibrium of well-fitting forms. However, for the fit to occur in practice, one vital condition must be satisfied. It must have time to happen. The process must be able to achieve equilibrium before the next culture change upsets it again... The direct response is the feedback of the process. If the process is to maintain the good fit ... while the culture drifts, it needs a feedback sensitive enough to take action the moment that one of the potential failures actually occurs.”

Biased Decisions and Perceptions

“The self-conscious individual's grasp of problems is constantly misled. His concepts and categories, besides being arbitrary and unsuitable, are self-perpetuating. Under the influence of concepts, he not only does things from a biased point of view, but sees them biasedly as well. The concepts control his perception of fit and misfit — until in the end he sees nothing but deviations from his conceptual dogmas, and loses not only the urge but even the mental opportunity to frame his problems more appropriately.”

Scott's Second Law

“When an error has been detected and corrected, it will be found to have been correct in the first place.
Corollary: After the correction has been found in error, it will be impossible to fit the original quantity back into the equation.”

Software Testing Completion Criteria

“Software is never completely fit. ... Testing should simply continue until all of the performance criteria have been met, including the failure rate.”

Models and Theories and Reality

"Until now, physical theories have been regarded as merely models with approximately describe the reality of nature. As the models improve, so the fit between theory and reality gets closer. Some physicists are now claiming that supergravity is the reality, that the model and the real world are in mathematically perfect accord."

Paul_Dirac

Beauty in Equations

“I think there is a moral to this story, namely that it is more important to have beauty in one's equations than to have them fit experiment. It seems that if one is working from the point of view of getting beauty into one's equations, and if one has a really sound insight, one is on a sure line of progress.”

Arts

“The arts alone give direct access to experience. To eliminate them from education - or worse, to tolerate them as cultural ornaments - is antieducational obscurantism. It is foisted on us by the pedants and snobs of Hellenistic Greece who considered artistic performance fit only for slaves...”

Scientific Method

“There are but two ways of forming an opinion in science. One is the scientific method; the other, the scholastic. One can judge from experiment, or one can blindly accept authority. To the scientific mind, experimental proof is all important and theory is merely a convenience in description, to be junked when it no longer fits. To the academic mind, authority is everything and facts are junked when they do not fit theory laid down by authority.”.

Purpose of Models

“The purpose of models is not to fit the data but to sharpen the questions.”

Alan_Perlis

Fit and Try

“Fundamentally, the procedure you mention, which is ‘fit-and-try’, will work very well with three or four people. If you have a hundred people the ‘fit-and-try’ process diverges because of lack of control.”

Specifications

“It is easier to change the specification to fit the program than vice versa.”

Herbert_Simon

Operational Research Restrictions

“The powerful algorithms associated with OR impose a strong mathematical structure on the decision problem. Their power is bought at the cost of shaping and squeezing the real-world problem to fit their computational requirements.”

John_Steinbeck

All Information Not In

“It is not enough to say that we cannot know or judge because all the information is not in. The process of gathering knowledge does not lead to knowing. A child's world spreads only a little beyond his understanding while that of a great scientist thrusts outward immeasurably. An answer is invariably the parent of a great family of new questions. So we draw worlds and fit them like tracings against the world about us, and crumple them when we find they do not fit and draw new ones.”
