Overconfidence by the programmer could be attacked by a system that introduced random errors into the program under test. The location and nature of these errors would be recorded inside the system but concealed from the programmer. The rate at which he found and removed these known errors could be used to estimate the rate at which he is removing unknown errors. A similar technique is used routinely by surveillance systems in which an operator is expected to spend eight hours at a stretch looking at a radar screen for very rare events — such as the passing of an unidentified aircraft. Tests of performance showed that it was necessary to introduce some nonzero rate of occurrence of artificial events in order to keep the operator in a satisfactory state of arousal. Moreover, since these events were under control of the system, it was able to estimate the current and overall performance of each operator.

The machine takes all of these multitudinous pulls and forces which are fed in as data, and quickly computes the course of action which would be the most economical vector of need satisfaction in this existential situation. This is the behavior of our hypothetical person. The defects which in most of us make this process untrustworthy are the inclusion of information which does not belong to this present situation, or the exclusion of information which does. It is when memories and previous learnings are fed into the computations as if they were this reality, and not memories and learnings, that erroneous behavioral answers arise. Or when certain threatening experiences are inhibited from awareness, and hence are withheld from the computation or fed into it in distorted form, this too produces error. But our hypothetical person would find his organism thoroughly trustworthy, because all of the available data would be used, and it would be present in accurate rather than distorted form. Hence his behavior would come as close as possible to satisfying all his needs — for enhancement, for affiliation with others, and the like.
The test of the machine is the satisfaction it gives you. There isn't any other test. If the machine produces tranquility it's right. If it disturbs you it's wrong until either the machine or your mind is changed.

View Planslack drama. Why is it that we reward programmers who work all night to remove the errors they put into their programs, or managers who make drastic organizational changes to resolve the crises their poor management has created? Why not reward the programmers who design so well that they don’t have dramatic errors, and managers whose organizations stay out of crisis mode? Organizing
It is a measure of the effort we are prepared to expend to guard against deception when accuracy is at a premium.
Although the method is simple, it shows how, mathematically, random brute force can overcome precise logic. It's a numerical approach that uses quantity to derive quality.
Is it not fair to say, “The program learned from experience”? Your immediate objection is that there was a program telling the machine how to learn. But when you take a course in Euclidean geometry, is not the teacher putting a similar learning program into you? Poorly, to be sure, but is that not, in a real sense, what a course in geometry is all about? You enter the course and cannot do problems; the teacher puts into you a program and at the end of the course you can solve such problems. Think it over carefully. If you deny the machine learns from experience because you claim the program was told (by the human programmer) how to improve its performance, then is not the situation much the same with you, except you are born with a somewhat larger initial program compared to the machine when it leaves the manufacturer’s hands? Are you sure you are not merely “programmed” in life by what chance events happen to you?

The government spying on people doesn’t literally make programmers write worse code. It just leads eventually to a world in which bad ideas will win. And because this is so important to hackers, they’re especially sensitive to it. They can sense totalitarianism approaching from a distance, as animals can sense an approaching thunderstorm.
Survival machines that can simulate the future are one jump ahead of survival machines who can only learn on the basis of overt trial and error. The trouble with overt trial is that it takes time and energy. The trouble with overt error is that it is often fatal. Simulation is both safer and faster. The evolution of the capacity to simulate seems to have cumulated in subjective consciousness.
We humans are the victims of an asymmetry in the perception of random events. We attribute our successes to our skills, and our failures to external events outside our control, namely to randomness.
Program testing can be a very effective way to show the presence of bugs, but it is hopelessly inadequate for showing their absence.

A programmer who truly sees his program as an extension of his own ego is not going to be trying to find all the errors in that program. On the contrary, he is going to be trying to prove that the program is correct — even if this means the oversight of errors which are monstrous to another eye. All programmers are familiar with the symptoms of this dissonance resolution — -in others, of course.
War is the province of chance. In no sphere of human activity is such a margin to be left for this intruder, because none is so much in constant contact with him on all sides. He increases the uncertainty of every circumstance, and deranges the course of events.
From this uncertainty of all intelligence and suppositions, this continual interposition of chance, the actor in War constantly finds things different from his expectations; and this cannot fail to have an influence on his plans, or at least on the presumptions connected with these plans. If this influence is so great as to render the pre-determined plan completely nugatory, then, as a rule, a new one must be substituted in its place; but at the moment the necessary data are often wanting for this, because in the course of action circumstances press for immediate decision, and allow no time to look about for fresh data, often not enough for mature consideration.
But it more often happens that the correction of one premise, and the knowledge of chance events which have arisen, are not sufficient to overthrow our plans completely, but only suffice to produce hesitation. Our knowledge of circumstances has increased, but our uncertainty, instead of having diminished, has only increased. The reason of this is, that we do not gain all our experience at once, but by degrees; thus our determinations continue to be assailed incessantly by fresh experience; and the mind, if we may use the expression, must always be “under arms”.
Printing mistakes adds value because of the probability calculus, which makes their intrusion into something problematic and almost impossible, even when everything's conceived, precisely, to avoid the intrusion of human error.
