There is always something to worry about. Avoid weekend thinking and ignoring the latest dire predictions of the newscasters. Sell a stock because the company's fundamentals deteriorate, not because the sky is falling.

... I came to the subject a True Believer in dark matter, but it was MOND that nailed the predictions for the LSB galaxies that I was studying (McGaugh & de Blok, 1998), not any flavor of dark matter. So what I am supposed to conclude?...

Nowadays, however, we are much more aware of the fact that the best proof in the world is worth no more than its premises: every scientific theory is transitory and provisional, in wait for a better one, and accepted only as long as the experimental results conform to its predictions.

In the absolute universe all events can be regarded as absolutely deterministic, and if we can't perceive the greater structures, it's because our vision is faulty. If we had a real grasp of causality down to the molecular level, we wouldn't need to rely on mathematical approximations, on statistics and probabilities, in making predictions. If our perceptions of cause and effect were only good enough, we'd be able to attain absolute knowledge of what is to come. We would make ourselves all-seeing.

Robert Silverberg

Rule 2. Any summary of a distribution of numbers in terms of symmetric functions should not give an objective degree of belief in any one of the inferences or predictions to be made therefrom that would cause human action significantly different from what this action would be if the original distributions had been taken as evidence.

Walter A. Shewhart

My approach works not by making valid predictions but by allowing me to correct false ones.

If there is a lesson in our story it is that the manipulation, according to strictly self-consistent rules, of a set of symbols representing one single aspect of the phenomena may produce correct, verifiable predictions, and yet completely ignore all other aspects whose ensemble constitutes reality...

Arthur Koestler

Scientific truth is characterized by its exactness and the certainty of its predictions. But these admirable qualities are contrived by science at the cost of remaining on a plane of secondary problems. leaving intact the ultimate and decisive questions. … Yet science is but a small part of the human mind and organism. Where it stops, man does not stop.

José Ortega y Gasset

I accept that climate change is a challenge, I accept the broad theory about global warming. I am sceptical about a lot of the more gloomy predictions.

Twenty years ago we heard many predictions that there would be no Indians left in Brazil by the end of the decade. These gloomy forecasts were wholly wrong. We are now optimists — hopeful that right thinking will prevail and the destruction of tribal peoples and their environments will stop. Tribal peoples will survive against extraordinary odds — but they do need the help of concerned people throughout the world.

Rule 1. Original data should be presented in a way that will preserve the evidence in the original data for all the predictions assumed to be useful.

Walter A. Shewhart

The confirmations of novel predictions resulting from bold conjectures are very important in the falsificationist account of the growth of science.

Four predictions of the Big Bang Theory have now been verified - surely enough to quench even the most biased critics.

Business success is less a function of grandiose predictions than it is a result of being able to respond rapidly to real changes as they occur.

Your imagination is the single most important asset you possess. Your imagination is your power to create mental pictures of things that don't exist yet and that you want to bring into being. Your imagination is what you use to shape your future. And so in your own way, you are a prophet. You generate countless predictions every day. Your imagination is the source, tirelessly churning out mental pictures of what you'll be doing in the future.

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.

In the early 1970s,... economists began to embrace the Rational Expectations Hypothesis (REH), according to which market participants' expectations are essentially the same as the predictions of the relevant economic theory (Muth 1961: 316). What has been largely overlooked is that, … REH theorists presume that the role of market participants' expectations in driving outcomes is not autonomous from the other components of the model. … Because REH models, by design, rule out an autonomous role for expectations, they are best viewed as derailing, rather than developing, the microfoundations approach.

If you learn one thing from having lived through decades of changing views, it is that all predictions are necessarily false.

What really made me angry though was finding myself agreeing with any of the journal's articles, and I did agree with several. The writers had a keen, if cold intelligence. They did a great deal of seeing through some of the nonsense concerned with the psychic field in general. Of course, they were almost vengefully gleeful when they could legitimately knock down some psychic performance, or show a psychic's predictions to be wrong. Only why couldn't they see their own scientific nonsense? And why couldn't their trained intellects perceive their own emotional vehemence? Because, I thought unhappily, they were scientific witch hunters.

I have seen some astrologers who predicted wonderful things; but I have no reason to believe they predicted them only from the stars, or anything of the sort. In many cases it is simply mind-reading. Sometimes wonderful predictions are made, but in many cases it is arrant trash.

Swami Vivekananda

The human brain is like a memory system that records every thing that happens to us and makes intelligent predictions based on those experiences.

Perhaps more striking is the accuracy of many of Marx's best-known qualitative predictions about the tendencies of capitalist development: capitalism continues to conquer the globe; its effect is the gradual erasure of cultural and regional identities; growing economic inequality is the norm in the advanced capitalist societies; where capitalism triumphs, market norms gradually dominate all spheres of life, public and private; class position continues to be the defining determinant of political outlook; the dominant class dominates the political process which, in turn, does its bidding; and so on.

In both quantum theory and general relativity, we encounter predictions of physically sensible quantities becoming infinite. This is likely the way that nature punishes impudent theorists who dare to break her unity.... If infinities are signs of missing unification, a unified theory will have none. It will be what we call a finite theory.

It is clear that in mulling over harsh judgments, sinister predictions, and bad memories, we fashion our own sadness; in a certain sense, we savor it.

Émile Chartier

No serious futurist deals in 'predictions'. These are left for television oracles and newspaper astrologers.
