“Human experience, which is constantly contradicting theory, is the great test of truth. A system, built upon the discoveries of a great many minds, is always of more strength, than what is produced by the mere workings of any one mind, which, of itself, can do very little. There is not so poor a book in the world that would not be a prodigious effort were it wrought out entirely by a single mind, without the aid of prior investigators.”

“Think of all the nonsense you had to learn in psychology courses. None of which was testable. None of which was measurable. We had behaviorism, Freudian psychology, all of these theories that you learn in psychology. Totally untestable. Now, we can test it, because physics allows us to calculate energy flows in the brain.”

“The NSF study projected a shortfall of 675,000 scientists and engineers without considering the future demand for such individuals in the marketplace. It simply observed a decline in the number of 22-year-olds and projected that this demographic trend would result in a huge shortfall. This could be termed the supply-side theory of labor market analysis. But making labor market projections without considering the demand side of the equation doesn't pass the laugh test with experts in the field.”

“But when men have realized that time has upset many fighting faiths, they may come to believe...that the best test of truth is the power of the thought to get itself accepted in the competition of the market... That at any rate is the theory of our constitution.”

“One of the greatest sources of problems in our society arises from people having loads of wrong theories in their heads - often theories that are critical of others - that they won't test by speaking to the relevant people about them. Instead, they talk behind people's backs, which leads to pervasive misinformation.”

“The material which a scientist actually has at his disposal, his laws, his experimental results, his mathematical techniques, his epistemological prejudices, his attitude towards the absurd consequences of the theories which he accepts, is indeterminate in many ways, ambiguous, and never fully separated from the historical background . This material is always contaminated by principles which he does not know and which, if known, would be extremely hard to test.”

“The test of science is not whether you are reasonable—there would not be much of physics if that was the case—the test is whether it works. And the great point about Newton’s theory of gravitation was that it worked, that you could actually say something about the motion of the moon without knowing very much about the constitution of the Earth.”

“I was never a prisoner of any theory. What guided me were reason and reality. The acid test I applied to every theory or scheme was: Would it work? The acid test is in performance, not promises. It is not from weakness that one commands respect. As long as the leaders take care of their people, they will obey the leaders.”

“No theory of government was ever given a fairer test or a more prolonged experiment in a democratic country than democratic socialism received in Britain. Yet it was a miserable failure in every respect... To cure the British disease with socialism was like trying to cure leukemia with leeches.”

“Our assumption is that God has not revealed all there is to know in the spiritual area any more than he has in these other areas. We, therefore, need to experiment in this area and, like scientists who work in other areas, develop and test theories in order to gain greater understanding”

“When men have realized that time has upset many fighting faiths, they may come to believe... that the ultimate good desired is better reached by free trade in ideas-- that the best test of truth is the power of the thought to get itself accepted in the competition of the market, and that truth is the only ground upon which their wishes safely can be carried out. That at any rate is the theory of our Constitution. It is an experiment. As all life is an experiment. Every year if not every day we wager our salvation upon some prophecy based upon imperfect knowledge.”

“The worst pain ... isn't the pain you feel at the time, it's the pain you feel later on when there's nothing you can do about it, They say that time heals all wounds, But we never live long enough to test that theory.”

“His brother maintained that what sent people backing away was neither his size nor his mother's blood, but solely the expression on his face. To test Samuel's theory, Charles had tried smiling - and then solemnly reported to Samuel that he had been mistaken. When Charles smiled, he told Samuel, people just ran faster.”

“For a moment, Jason could only stand there in the hallway with his nose pressed up against the cold wood of her door. After a few seconds, he knocked politely. Taylor whipped open the door, unamused. Jason grinned at her. “I just gotta ask: Where did you get the whole ‘all the cute girls run around naked’ thing?” “I defend sexual harassment cases, Mr. Andrews,” she replied coolly. "I’ve seen and heard things even you haven’t thought of.” “Care to test out that theory?” She slammed the door in his face again.”

“I venture to define science as a series of interconnected concepts and conceptual schemes arising from experiment and observation and fruitful of further experiments and observations. The test of a scientific theory is, I suggest, its fruitfulness.”

“There is not enough evidence, consistent evidence to make it as fact, and I say that because for theory to become a fact, it needs to consistently have the same results after it goes through a series of tests. The tests that they put- that they use to support evolution do not have consistent results. Now too many people are blindly accepting evolution as fact. But when you get down to the hard evidence, it's merely a theory.”

“The mathematical framework of quantum theory has passed countless successful tests and is now universally accepted as a consistent and accurate description of all atomic phenomena. The verbal interpretation, on the other hand - i.e., the metaphysics of quantum theory - is on far less solid ground. In fact, in more than forty years physicists have not been able to provide a clear metaphysical model.”

“When you're operating on uninvestigated theories of what's going on and you aren't even aware of it, you're in what I call "the dream." Often the dream becomes troubling; sometimes it even turns into a nightmare. At times like these, you may want to test the truth of your theories by doing The Work on them. The Work always leaves you with less of your uncomfortable story. Who would you be without it? How much of your world is made up of unexamined stories? You'll never know until you inquire.”

“I therefore took this opportunity and also began to consider the possibility that the Earth moved. Although it seemed an absurd opinion, nevertheless, because I knew that others before me had been granted the liberty of imagining whatever circles they wished to represent the phenomena of the stars, I thought that I likewise would readily be allowed to test whether, by assuming some motion of the Earth's, more dependable representations than theirs could be found for the revolutions of the heavenly spheres.”

“It is easy to obtain confirmations, or verifications, for nearly every theory-if we look for confirmations. Confirmations should count only if they are the result of risky predictions... A theory which is not refutable by any conceivable event is non-scientific. Irrefutability is not a virtue of a theory (as people often think) but a vice. Every genuine test of a theory is an attempt to falsify it, or refute it.”

“Whether statistics be an art or a science... or a scientific art, we concern ourselves little. It is the basis of social and political dynamics, and affords the only secure ground on which the truth or falsehood of the theories and hypotheses of that complicated science can be brought to the test.”

“There never comes a point where a theory can be said to be true. The most that one can claim for any theory is that it has shared the successes of all its rivals and that it has passed at least one test which they have failed.”

“The test of a theory is its ability to cope with all the relevant phenomena, not its a priori 'reasonableness'. The latter would have proved a poor guide in the development of science, which often makes progress by its encounter with the totally unexpected and initially extremely puzzling.”

“The first issue to be settled is whether socialism has a right to exist. Are its allegations concerning the present system true? Is industry proceeding on a principle of fraud? I wish to test the power of recent economic theory to give an exact answer to this question.”
