People Characteristics

"People, as active devices, have success modes and failure modes. The following are the main ones that I have named and used to date:
1. People are communicating beings, doing best face-to-face, in person, with real-time question and answer.
2. People have trouble acting consistently over time.
3. People are highly variable, varying from day to day and place to place.
4. People generally want to be good citizens, are good at looking around, taking initiative, and doing 'whatever is needed' to get the project to work.
There are other characteristics that I won’t expand here:
- People need both think time and communicating opportunities...
- People work well from examples...
- People prefer to fail conservatively than to risk succeeding differently; prefer to invent than to research, can only keep a small amount in their heads, and do make mistakes, and find it hard to change their habits.
- Individual personalities easily dominate a project.
- A person’s personality profile strongly affects their ability to perform specific assignments."

Cheeseburgers

"Development is inherently different from production. But managers of development and allied efforts often allow their thinking to be shaped by a management philosophy derived entirely from a production environment.
Imagine for the moment that you’re the manager of the local fast food franchise. It makes perfect sense for you to take any or all of the following efficient production measures:
- Squeeze out error. Make the machine (the human machine) run as smoothly as possible.
- Take a hard line about people goofing off on the job.
- Treat workers as interchangeable pieces of the machine.
- Optimize the steady state. (Don’t even think about how the operation got up to speed, or what it would take to close it down.)
- Standardize procedure. Do everything by the book.
- Eliminate experimentation—that’s what the folks at headquarters are paid for.
These would be reasonable approaches if you were in the fast food business (or any production environment), but you’re not. The 'make a cheeseburger, sell a cheeseburger' mentality can be fatal in your development area. It can only serve to damp your people’s spirits and focus their attention away from the real problems at hand. This style of management will be directly at odds with the work.
To manage thinking workers effectively, you need to take measures nearly opposite those listed above."

Programming Styles

“There are very different programming styles. I tend to see them as Mozart versus Beethoven. When Mozart started to write, the composition was finished. He wrote the manuscript and it was 'aus einem Guss' (from one cast). In beautiful handwriting, too. Beethoven was a doubter and a struggler who started writing before he finished the composition and then glued corrections onto the page. In one place he did this nine times. When they peeled them, the last version proved identical to the first one.”

Ordering Others About

“It does not follow from the separation of planning and doing in the analysis of work that the planner and the doer should be two different people. It does not follow that the industrial world should be divided into two classes of people: a few who decide what is to be done, design the job, set the pace, rhythm and motions, and order others about; and the many who do what and as they are told.”

Insoluble Problems

“I always worked with the temperamental conviction that fundamentally there are no insoluble problems, and experience justified me in so far as I have often seen individuals simply outgrow a problem which had destroyed others. This ‘outgrowing’, as I formerly called it, on further experience was seen to consist in a new level of consciousness. Some higher or wider interest arose on the person's horizon, and through this widening of his view the insoluble problem lost its urgency. It was not solved logically in its own terms, but faded out when confronted with a new and stronger life-tendency. It was not repressed and made unconscious, but merely appeared in a different light, and so did indeed become different. What, on a lower level, had led to the wildest conflicts and to panicky outbursts of emotion, viewed from the higher level of the personality, now seemed like a storm in the valley seen from a high mountain-top. This does not mean that the thunderstorm is robbed of its reality, but instead of being in it, one is now above it. However, since we are both valley and mountain with respect to the psyche, it might seem a vain illusion to feel oneself beyond what is human. One certainly does feel the affect and is shaken and tormented by it, yet at the same time one is aware of a higher consciousness, which prevents one from becoming identical with the affect, a consciousness which takes the affect objectively, and can say, Ί know that I suffer'.”

Why is the Kettle Boiling?

“The distinguished geologist Frank Rhodes made this point back in 1965, using the analogy of a boiling kettle. So why is the kettle boiling? Rhodes notes that two types of explanation might be given. At the scientific level, energy is being supplied, which raises the temperature of the water to its boiling point. Yet another answer can be given. 'The kettle is boiling because I put it on to make a cup of tea.' Rhodes makes a point which some of you may find predictable, but is none the less important. Here is what he says: 'Now these are different answers. But both are true, both are complementary and not competitive. One answer is appropriate within a particular frame of reference, the other within another frame of reference. There is a sense in which each is incomplete without the other.”
  • Note: Frank Rhodes gave credit for the kettle analogy to Dr. Douglas Spanner.

Neurons to Consciousness

“None of us has a brain that can actually put us in touch with reality unaided with truth. I've just shown you a bunch of gadgetry that responds to things that are essential to our survival, things that prevent us from falling off cliffs and bumping into trees. But they don't actually correspond to any clear description of the world as it is. So we have, for example, circuitry that responds to the edges rather than the physical distribution of light, because edges are important, that's where objects leave off and their backgrounds begin. Moreover, they can be fooled, as I did with each one of you. That since our neural circuitry does consist of a mechanism, not a pipeline to the truth or a window onto objective reality. That is naïve realism we know is false because there are illusions. You can't just trust your senses. That means we need some way of augmenting the faculties that nature gave us to make our beliefs as accurate as possible. Which of course is why the early modern philosophers made such a big deal of visual illusions. They said you can't just open your eyes and see the world as it is. Look at all these illusions. So what we do, what gives some of us confidence that our beliefs are objectively true is that they are part of an institutional infrastructure of testing and criticism and logic and determining which hypotheses withstand criticism and attempts at refutation. Devising exotic arrangements of reality to reflect the way reality is put together, namely experiments. Thanks to this huge network of minds, each one of them making up for deficits of all the others, we like to think that we have a collective grasp on truth that none of us individually can have. But of course, it's always fallible. The religious beliefs I think were actually pretty reasonable hypotheses in earlier states of our collective knowledge. Even Richard Dawkins said that before Darwin he probably would have been a creationist because the cosmic engineer was the only available explanation for the obvious adaptive complexity of living things. I would add that prior to the advent of modern neuroscience I probably would have believed in souls because there was no better explanation for phenomena such as that people respond intelligently to their environments. When you dream some part of you is up and about the world while your body is in bed the whole time. That seems like there must be some part of you that can leave your body. When a person suddenly dies some kind of animating force no longer seems to be animating the body that was there just a few minutes ago. So the soul hypothesis is not a stupid or irrational belief, nor is creationism if it's the best that you have. Now, of course, we can do better. But doing better in part depends not just on this cumulative weight of evidence and argument. But because few of us can actually reconstruct the scientific observations that justify the theory of natural selection or the theory of neural networks, all of us, at least a little bit, take it on faith in the following sense; that there is a community that you trust enough because when they have been challenged to defend their beliefs they can connect them to reality. They have shown that it isn't magic. That they have given reason to trust them because they've convinced you that they're the mores of their culture, of their scientific culture, designed so that they will find true things and weed out false things. If you don't have a degree of solidarity or trust, if you think that scientists are all in cahoots with big corporations or are trying to tear down all faith and values and meaning and you simply refuse to follow through the very long chain of deduction that connects the claims to the experiments, then you'll naturally reject it just because it's not your tribe. For you and me scientists are our tribe and we're apt to give them some credibility, indeed some credulousness, knowing that if ever challenged it would be repaid. But unless you trace that through it can be all too easy to reject the conclusions of science, and indeed a number of studies have shown that contrary to the common belief that people believe in falsehoods, such as that vaccines cause autism or that humans were created five thousand years ago or that the burning of fossil fuels has no effect on global temperatures, it turns out that people with those beliefs that we have every reason to believe are false are no more scientifically naïve on average than people that have beliefs that are scientifically justified. You give a test on evolution to a bunch of people who believe in evolution, give it to a bunch of creationists, there's not much difference in how well they score. In fact, often they are equal. Likewise, the typical grasp of climate science among someone who signs on to the scientific consensus is not much better than the adamant deniers. That kind of dashes the hope that simply by increasing the quality of science education you will lead people to more accurate beliefs. There, in addition, has to be a dissociation of who you think are the good guys and who are the bad guys from who has the best claims to truth. That's what it depends on.”

Theory Personality

“Understanding a theory has, indeed, much in common with understanding a human personality. We may know or understand a man's system of dispositions pretty well; that is to say, we may be able to predict how he would act in a number of different situations. But since there are infinitely many possible situations, of infinite variety, a full understanding of a man's dispositions does not seem to be possible.”

Picture of Scientific Method

“The picture of scientific method drafted by modern philosophy is very different from traditional conceptions. Gone is the ideal of a universe whose course follows strict rules, a predetermined cosmos that unwinds itself like an unwinding clock. Gone is the ideal of the scientist who knows the absolute truth. The happenings of nature are like rolling dice rather than like revolving stars; they are controlled by probability laws, not by causality, and the scientist resembles a gambler more than a prophet. He can tell you only his best posits — he never knows beforehand whether they will come true. He is a better gambler, though, than the man at the green table, because his statistical methods are superior. And his goal is staked higher — the goal of foretelling the rolling dice of the cosmos. If he is asked why he follows his methods, with what title he makes his predictions, he cannot answer that he has an irrefutable knowledge of the future; he can only lay his best bets. But he can prove that they are best bets, that making them is the best he can do — and if a man does his best, what else can you ask of him?”

Inherent Unpredictability

“The inherent unpredictability of future scientific developments — the fact that no secure inference can be drawn from one state of science to another — has important implications for the issue of the limits of science. It means that present-day science cannot speak for future science: it is in principle impossible to make any secure inferences from the substance of science at one time about its substance at a significantly different time. The prospect of future scientific revolutions can never be precluded. We cannot say with unblinking confidence what sorts of resources and conceptions the science of the future will or will not use. Given that it is effectively impossible to predict the details of what future science will accomplish, it is no less impossible to predict in detail what future science will not accomplish. We can never confidently put this or that range of issues outside 'the limits of science', because we cannot discern the shape and substance of future science with sufficient clarity to be able to say with any assurance what it can and cannot do. Any attempt to set 'limits' to science — any advance specification of what science can and cannot do by way of handling problems and solving questions — is destined to come to grief.”

Persecution Used In Theology

“Persecution is used in theology, not in arithmetic, because in arithmetic there is knowledge, but in theology there is only opinion. So, whenever you find yourself getting angry about a difference of opinion, be on your guard, you will probably find, on examination, that your belief is going beyond what the evidence warrants.”

Significance of Fact

“The significance of a fact is relative to [the general body of scientific] knowledge. To say that a fact is significant in science, is to say that it helps to establish or refute some general law; for science, though it starts from observation of the particular, is not concerned essentially with the particular, but with the general. A fact, in science, is not a mere fact, but an instance. In this the scientist differs from the artist, who, if he deigns to notice facts at all, is likely to notice them in all their particularity.”

George_Sarton

Scientific Progress

“No history of civilization can be tolerably complete which does not give considerable space to the explanation of scientific progress. If we had any doubts about this, it would suffice to ask ourselves what constitutes the essential difference between our and earlier civilizations. Throughout the course of history, in every period, and in almost every country, we find a small number of saints, of great artists, of men of science. The saints of today are not necessarily more saintly than those of a thousand years ago; our artists are not necessarily greater than those of early Greece; they are more likely to be inferior; and of course, our men of science are not necessarily more intelligent than those of old; yet one thing is certain, their knowledge is at once more extensive and more accurate. The acquisition and systematization of positive knowledge is the only human activity which is truly cumulative and progressive. Our civilization is essentially different from earlier ones, because our knowledge of the world and of ourselves is deeper, more precise, and more certain, because we have gradually learned to disentangle the forces of nature, and because we have contrived, by strict obedience to their laws, to capture them and to divert them to the gratification of our own needs.”

Just and Unjust Regulation

Three Great Orders

“The whole annual produce of the land and labour of every country... naturally divides itself, it has already been observed, into three parts; the rent of land, the wages of labour, and the profits of stock; and constitutes a revenue to three different orders of people; to those who live by rent, to those who live by wages, and to those who live by profit. These are the three great, original, and constituent orders of every civilised society... The interest of the first of those three great orders, it appears from what has been just now said, is strictly and inseparably connected with the general interest of the society. Whatever either promotes or obstructs the one, necessarily promotes or obstructs the other... The interest of the second order, that of those who live by wages, is as strictly connected with the interest of the society as that of the first... Employers constitute the third order, that of those who live by profit. It is the stock that is employed for the sake of profit which puts into motion the greater part of the useful labour of every society... But the rate of profit does not, like rent and wages, rise with the prosperity and fall with the declension of the society. On the contrary... The interest of this third order, therefore, has not the same connection with the general interest of the society as that of the other two... The interest of the dealers... is always in some respects different from, and even opposite to, that of the public. To widen the market and to narrow the competition... The proposal of any new law or regulation of commerce which comes from this order ought always to be listened to with great precaution, and ought never to be adopted till after having been long and carefully examined, not only with the most scrupulous, but with the most suspicious attention. It comes from an order of men whose interest is never exactly the same with that of the public, who have generally an interest to deceive and even to oppress the public, and who accordingly have, upon many occasions, both deceived and oppressed it.”

William_Whewell

Prediction of Facts

“We have here spoken of the prediction of facts of the same kind as those from which our rule was collected. But the evidence in favour of our induction is of a much higher and more forcible character when it enables us to explain and determine cases of a kind different from those which were contemplated in the formation of our hypothesis. The instances in which this has occurred, indeed, impress us with a conviction that the truth of our hypothesis is certain. No accident could give rise to such an extraordinary coincidence. No false supposition could, after being adjusted to one class of phenomena, so exactly represent a different class, when the agreement was unforeseen and contemplated. That rules springing from remote and unconnected quarters should thus leap to the same point, can only arise from that being where truth resides.”

Technology Leadership

“The questions that we face today are finally about leadership. Will there be leaders who are able to recognize the historical moment and the choices it presents? Will they find ways to create the organizational conditions in which new visions, new concepts, and a new language of workplace relations can emerge? Will they be able to create organizational innovations that can exploit the unique capacities of the new technology and thus mobilize their organization's productive potential to meet the heightened rigors of global competition? Will there be leaders who understand the crucial role that human beings from each organizational stratum can play in adding value to the production of goods and services? If not, we will be stranded in a new world with old solutions. We will suffer through the unintended consequences of change, because we have failed to understand this technology and how it differs from what came before.”
