So far we have only scattered beginnings of the new doctrine, only tentative efforts and disconnected attempts which have started, sometimes in economic, and sometimes in psychological, quarters. The time when an exact psychology of business life will be presented as a closed and perfected system lies very far distant.

APPLIED PSYCHOLOGYOur aim is to sketch the outlines of a new science which is to intermediate between the modern laboratory psychology and the problems of economics: the psychological experiment is systematically to be placed at the service of commerce and industry. So far we have only scattered beginnings of the new doctrine, only tentative efforts and disconnected attempts which have started, sometimes in economic, and sometimes in psychological, quarters. The time when an exact psychology of business life will be presented as a closed and perfected system lies very far distant. But the earlier the attention of wider circles is directed to its beginnings and to the importance and bearings of its tasks, the quicker and the more sound will be the development of this young science. What is most needed to-day at the beginning of the new movement are clear, concrete illustrations which demonstrate the possibilities of the new method. In the following pages, accordingly, it will be my aim to analyze the results of experiments which have actually been carried out, experiments belonging to many different spheres of economic life. But these detached experiments ought always at least to point to a connected whole; the single experiments will, therefore, always need a general discussion of the principles as a background. In the interest of such a wider perspective we may at first enter into some preparatory questions of theory. They may serve as an introduction which is to lead us to the actual economic life and the present achievements of experimental psychology.It is well known that the modern psychologists only slowly and very reluctantly approached the apparently natural task of rendering useful service to practical life. As long as the study of the mind was entirely dependent upon philosophical or theological speculation, no help could be expected from such endeavors to assist in the daily walks of life. But half a century has passed since the study of consciousness was switched into the tracks of exact scientific investigation. Five decades ago the psychologists began to devote themselves to the most minute description of the mental experiences and to explain the mental life in a way which was modeled after the pattern of exact natural sciences. Their aim was no longer to speculate about the soul, but to find the psychical elements and the constant laws which control their connections. Psychology became experimental and physiological. For more than thirty years the psychologists have also had their workshops. Laboratories for experimental psychology have grown up in all civilized countries, and the new method has been applied to one group of mental traits after another. And yet we stand before the surprising fact that all the manifold results of the new science have remained book knowledge, detached from any practical interests. Only in the last ten years do we find systematic efforts to apply the experimental results of psychology to the needs of society.It is clear that the reason for this late beginning is not an unwillingness of the last century to make theoretical knowledge serviceable to the demands of life. Every one knows, on the contrary, that the glorious advance of the natural sciences became at the same time a triumphal march of technique. Whatever was brought to light in the laboratories of the physicists and chemists, of the physiologists and pathologists, was quickly transformed into achievements of physical and chemical industry, of medicine and hygiene, of agriculture and mining and transportation. No realm of the external social life remained untouched. The scientists, on the other hand, felt that the far-reaching practical effect which came from their discoveries exerted a stimulating influence on the theoretical researches themselves. The pure search for truth and knowledge was not lowered when the electrical waves were harnessed for wireless telegraphy, or the Roentgen rays were forced into the service of surgery. The knowledge of nature and the mastery of nature have always belonged together.The persistent hesitation of the psychologists to make similar practical use of their experimental results has therefore come from different causes. The students of mental life evidently had the feeling that quiet, undisturbed research was needed for the new science of psychology in order that a certain maturity might be reached before a contact with the turmoil of practical life would be advisable. The sciences themselves cannot escape injury if their results are forced into the rush of the day before the fundamental ideas have been cleared up, the methods of investigation really tried, and an ample supply of facts collected. But this very justified reluctance becomes a real danger if it grows into an instinctive fear of coming into contact at all with practical life. To be sure, in any single case there may be a difference of opinion as to when the right time has come and when the inner consolidation of a new science is sufficiently advanced for the technical service, but it ought to be clear that it is not wise to wait until the scientists have settled all the theoretical problems involved. True progress in every scientific field means that the problems become multiplied and that ever new questions keep coming to the surface. If the psychologists were to refrain from practical application until the theoretical results of their laboratories need no supplement, the time for applied psychology would never come. Whoever looks without prejudice on the development of modern psychology ought to acknowledge that the hesitancy which was justified in the beginning would to-day be inexcusable lack of initiative. For the sciences of the mind too, the time has come when theory and practice must support each other. An exceedingly large mass of facts has been gathered, the methods have become refined and differentiated, and however much may still be under discussion, the ground common to all is ample enough to build upon.Another important reason for the slowness of practical progress was probably this. When the psychologists began to work with the new experimental methods, their most immediate concern was to get rid of mere speculation and to take hold of actual facts. Hence they regarded the natural sciences as their model, and, together with the experimental method which distinguishes scientific work, the characteristic goal of the sciences was accepted too. This scientific goal is always the attainment of general laws; and so it happened that in the first decades after the foundation of psychological laboratories the general laws of the mind absorbed the entire attention and interest of the investigators. The result of such an attitude was, that we learned to understand the working of the typical mind, but that all the individual variations were almost neglected. When the various individuals differed in their mental behavior, these differences appeared almost as disturbances which the psychologists had to eliminate in order to find the general laws which hold for every mind. The studies were accordingly confined to the general averages of mental experience, while the variations from such averages were hardly included in the scientific account. In earlier centuries, to be sure, the interest of the psychological observers had been given almost entirely to the rich manifoldness of human characters and intelligences and talents. In the new period of experimental work, this interest was taken as an indication of the unscientific fancies of the earlier age, in which the curious and the anecdotal attracted the view. The new science which was to seek the laws was to overcome such popular curiosity. In this sign experimental psychology has conquered. The fundamental laws of the ideas and of the attention, of the memory and of the will, of the feeling and of the emotions, have been elaborated. Yet it slowly became evident that such one-sidedness, however necessary it may have been at the beginning, would make any practical application impossible. In practical life we never have to do with what is common to all human beings, even when we are to influence large masses; we have to deal with personalities whose mental life is characterized by particular traits of nationality, or race, or vocation, or sex, or age, or special interests, or other features by which they differ from the average mind which the theoretical psychologist may construct as a type. Still more frequently we have to act with reference to smaller groups or to single individuals whose mental physiognomy demands careful consideration. As long as experimental psychology remained essentially a science of the mental laws, common to all human beings, an adjustment to the practical demands of daily life could hardly come in question. With such general laws we could never have mastered the concrete situations of society, because we should have had to leave out of view the fact that there are gifted and ungifted, intelligent and stupid, sensitive and obtuse, quick and slow, energetic and weak individuals.But in recent years a complete change can be traced in our science. Experiments which refer to these individual differences themselves have been carried on by means of the psychological laboratory, at first reluctantly and in tentative forms, but within the last ten years the movement has made rapid progress. To-day we have a psychology of individual variations from the point of view of the psychological laboratory.[1]This development of schemes to compare the differences between the individuals by the methods of experimental science was after all the most important advance toward the practical application of psychology. The study of the individual differences itself is not applied psychology, but it is the presupposition without which applied psychology would have remained a phantom.

THE DEMANDS OF PRACTICAL LIFE

While in this way the progress of psychology itself and the development of the psychology of individual differences favored the growth of applied psychology, there arose at the same time an increasing demand in the midst of practical life. Especially the teachers and the physicians, later the lawyers as well, looked for help from exact psychology. The science of education and instruction had always had some contact with the science of the mind, as the pedagogues could never forget that the mental development of the child has to stand in the centre of educational thought. For a long while pedagogy was still leaning on a philosophical psychology, after that old-fashioned study of the soul had been given up in psychological quarters. At last, in the days of progressive experimental psychology, the time came when the teachers under the pressure of their new needs began to inquire how far the modern laboratory could aid them in the classroom. The pedagogical psychology of memory, of attention, of will, and of intellect was systematically worked up by men with practical school interests. We may notice in the movement a slow but most important shifting. At first the results of theoretical psychology were simply transplanted into the pedagogical field. Experiments which were carried on in the interest of pure theoretical science were made practical use of, but their application remained a mere chance by-product. Only slowly did the pedagogical problems themselves begin to determine the experimental investigation. The methods of laboratory psychology were applied for the solving of those problems which originated in the school experience, and only when this point was reached could a truly experimental pedagogy be built on a psychological foundation. We stand in the midst of this vigorous and healthy movement, which has had a stimulating effect on theoretical psychology itself.

We find a similar situation in the sphere of the physician. He could not pass by the new science of the mind without instinctively feeling that his medical diagnosis and therapy could be furthered in many directions by the experimental method. Not only the psychiatrist and nerve specialist, but in a certain sense every physician had made use of a certain amount of psychology in his professional work. He had always had to make clear to himself the mental experiences of the patient, to study his pain sensations and his feelings of comfort, his fears and his hopes, his perceptions and his volitions, and to a certain degree he had always tried to influence the mental life of the patient, to work on him by suggestion and to help him by stimulating his mind. But as far as a real description and explanation of such mental experiences came in question, all remained a dilettantic semi-psychology which worked with the most trivial conceptions of popular thinking. The medical men recognized the disproportion between the exactitude of their anatomical, physiological, and pathological observation and the superficiality of their self-made psychology. Thus the desire arose in their own medical circle to harmonize their psychological means of diagnosis and therapy with the schemes of modern scientific psychology. The physician who examines the sensations in a nervous disease, or the intelligence in a mental disease, or heals by suggestion or hypnotism, tries to apply the latest discoveries of the psychological laboratory. But here, too, the same development as in pedagogy can be traced. The physicians at first made use only of results which had been secured under entirely different points of view, but later the experiments were subordinated to the special medical problems. Then the physician was no longer obliged simply to use what he happened to find among the results of the theoretical psychologist, but carried on the experiments in the service of medical problems. The independent status of experimental medical psychology could be secured only by this development.

In somewhat narrower limits the same may be said as to the problems of law. A kind of popular psychology was naturally involved whenever judges or lawyers analyzed the experience on the witness stand or discussed the motives of crime or the confessions of the criminal or the social conditions of criminality. But when every day brought new discoveries in the psychological laboratory, it seemed natural to make use of the new methods and of the new results in the interest of the courtroom. The power of observation in the witness, the exactitude of his memory, the character of his illusions and imagination, his suggestibility and his feeling, appeared in a new light in view of the experimental investigations, and the emotions and volitions of the criminal were understood with a new insight. Here, too, the last step was taken. Instead of being satisfied with experiments which the psychologist had made for his own purposes, the students of legal psychology adjusted experiments to the particular needs of the courtroom. Investigations were carried on to determine, the fidelity of testimony or to find methods for the detection of hidden thoughts and so on. Efforts toward the application of psychology have accordingly grown up in the fields of pedagogy, medicine, and jurisprudence, but as these studies naturally do not remain independent of one another, they all together form the one unified science of applied psychology.[2]

As soon as the independence of this new science was felt, it was natural that new demands and new problems should continue to originate within its own limits. There must be applied psychology wherever the investigation of mental life can be made serviceable to the tasks of civilization. Criminal law, education, medicine, certainly do not constitute the totality of civilized life. It is therefore the duty of the practical psychologist systematically to examine how far other purposes of modern society can be advanced by the new methods of experimental psychology. There is, for instance, already, far-reaching agreement that the problems of artistic creation, of scientific observation, of social reform, and many similar endeavors must be acknowledged as organic parts of applied psychology. Only one group of purposes is so far surprisingly neglected in the realm of the psychological laboratory: the purposes of the economic life, the purposes of commerce and industry, of business and the market in the widest sense of the word. The question how far applied psychology can be extended in this direction is the topic of the following discussions.

III

MEANS AND ENDS

Applied psychology is evidently to be classed with the technical sciences. It may be considered as psychotechnics, since we must recognize any science as technical if it teaches us to apply theoretical knowledge for the furtherance of human purposes. Like all technical sciences, applied psychology tells us what we ought to do if we want to reach certain ends; but we ought to realize at the threshold where the limits of such a technical science lie, as they are easily overlooked, with resulting confusion. We must understand that every technical science says only: you must make use of this means, if you wish to reach this or that particular end. But no technical science can decide within its limits whether the end itself is really a desirable one. The technical specialist knows how he ought to build a bridge or how he ought to pierce a tunnel, presupposing that the bridge or the tunnel is desired. But whether they are desirable or not is a question which does not concern the technical scientist, but which must be considered from economic or political or other points, of view. Everywhere the engineer must know how to reach an end, and must leave it to others to settle whether the end in itself is desirable. Often the end may be a matter of course for every reasonable being. The extreme case is presented by the applied science of medicine, where the physician subordinates all his technique to the end of curing the patient. Yet if we are consistent we must acknowledge that all his medical knowledge can prescribe to him only that he proceed in a certain way if the long life of the patient is acknowledged as a desirable end. The application of anatomy, physiology, and pathology may just as well be used for the opposite end of killing a man. Whether it is wise to work toward long life, or whether it is better to kill people, is again a problem which lies outside the sphere of the applied sciences. Ethics or social philosophy or religion have to solve these preliminary' questions. The physician as such has only to deal with the means which lead toward that goal.

We must make the same discrimination in the psychotechnical field. The psychologist may point out the methods by which an involuntary confession can be secured from a defendant, but whether it is justifiable to extort involuntary confessions is a problem which does not concern the psychologist. The lawyers or the legislators must decide as to the right or wrong, the legality or illegality, of forcing a man to show his bidden ideas. If such an end is desirable, the psychotechnical student can determine the right means, and that is the limit of his office. We ought to keep in mind that the same holds true for the application of psychology in economic life. Economic psychotechnics may serve certain ends of commerce and industry, but whether these ends are the best ones is not a care with which the psychologist has to be burdened. For instance, the end may be the selection of the most efficient laborers for particular industries. The psychologist may develop methods in his laboratory by which this purpose can be fulfilled. But if some mills prefer another goal,—for instance, to have not the most efficient but the cheapest possible laborers,—entirely different means for the selection are necessary. The psychologist is, therefore, not entangled in the economic discussions of the day; it is not his concern to decide whether the policy of the trusts or the policy of the trade-unions or any other policy for the selection of laborers is the ideal one. He is confined to the statement; if you wish this end, then you must proceed in this way; but it is left to you to express your preference among the ends. Applied psychology can, therefore, speak the language of an exact science in its own field, independent of economic opinions and debatable partisan interests. This is necessary limitation, but in this limitation lies the strength of the new science. The psychologist may show how a special commodity can be advertised; but whether from a social point of view it is desirable to reinforce the sale of these goods is no problem for psychotechnics. If a sociologist insists that it would be better if not so many useless goods were bought, and that the aim ought rather to be to protect the buyer than to help the seller, the psychologist would not object. His interest would only be to find the right psychological means to lead to this other social end. He is partisan neither of the salesman nor of the customer, neither of the capitalist nor of the laborer, he is neither Socialist nor anti-Socialist, neither high-tariff man nor free-trader. Here, too, of course, there are certain goals which are acknowledged on all sides, and which therefore hardly need any discussion, just as in the case of the physician, where the prolongation of life is practically acknowledged as a desirable end by every one. But everywhere where the aim is not perfectly a matter of course, the psychotechnical specialist fulfills his task only when he is satisfied with demonstrating that certain psychical means serve a certain end, and that they ought to be applied as soon as that end is accepted.

The whole system of psychotechnical knowledge might be subdivided under either of the two aspects. Either we might start from the various mental processes and ask for what end each mental factor can be practically useful and important, or we can begin with studying what significant ends are acknowledged in our society and then we can seek the various psychological facts which are needed as means for the realization of these ends. The first way offers many conveniences. There we should begin with the mental states of attention, memory, feeling, and so on, and should study how the psychological knowledge of every one of these mental states can render service in many different practical fields. The attention, for instance, is important in the classroom when the teacher tries to secure the attention of the pupils, but the judge expects the same attention from the jurymen in the courtroom, the artist seeks to stir up the attention of the spectator, the advertiser demands the attention of the newspaper readers. Whoever studies the characteristics of the mental process of attention may then be able to indicate how in every one of these unlike cases the attention can be stimulated and retained. Nevertheless the opposite way which starts from the tasks to be fulfilled seems more helpful and more fundamentally significant. The question, then, is what mental processes become important for the tasks of education, what for the purposes of the courtroom, what for the hospital, what for the church, what for politics, and so on.

As this whole essay is to be devoted exclusively to the economic problems, we are obliged to choose the second way; that is, to arrange applied psychology with reference to its chief ends and not with reference to the various means. But the same question comes up in the further subdivision of the material. In the field of economic psychology, too, we might ask how far the study of attention, or of perception, or of feeling, or of will, or of memory, and so on, can be useful for the purposes of the business man. Or here, too, we might begin with the consideration of the various ends and purposes. The ends of commerce are different from those of industry, those of publishing different from those of transportation, those of agriculture different from those of mining; or, in the field of commerce, the purposes of the retailer are different from those of the wholesale merchant. There can be no limit to such subdivisions; each particular industry has its own aims, and in the same industry a large variety of tasks are united. We should accordingly be led to an ample classification of special economic ends with pigeonholes for every possible kind of business and of labor. The psychologist would have to find for every one of these ends the right mental means. This would be the ideal system of economic psychology.

But we are still endlessly far from such a perfect system. Modern educational psychology and medical psychology have reached a stage at which an effort for such a complete system might be realized, but economic psychology is still at too early a stage of development. It would be entirely artificial to-day to aim at such ideal completeness. If we were to construct such a complete system of questions, we should have no answers. In the present stage nothing can be seriously proposed but the selection of a few central purposes which occur in every department of business life, and a study of the means to reach these special ends by the discussion of some typical cases which may clearly illustrate the methods involved.

From this point of view we select three chief purposes of business life, purposes which are important in commerce and industry and every economic endeavor. We ask how we can find the men whose mental qualities make them best fitted for the work which they have to do; secondly, under what psychological conditions we can secure the greatest and most satisfactory output of work from every man; and finally, how we can produce most completely the influences on human minds which are desired in the interest of business. In other words, we ask how to find the best possible man, how to produce the best possible work, and how to secure the best possible effects.

THE BEST POSSIBLE MAN

VOCATION AND FITNESS

Instead of lingering over theoretical discussions, we will move straight on toward our first practical problem. The economic task, with reference to which we want to demonstrate the new psychotechnic method, is the selection of those personalities which by their mental qualities are especially fit for a particular kind of economic work. This problem is especially useful to show what the new method can do and what it cannot do. Whether the method is sufficiently developed to secure full results to-day, or whether they will come to-morrow, is unimportant. It is clear that the success of to-morrow is to be hoped for, only if understanding and interest in the problem is already alive to-day.

When we inquire into the qualities of men, we use the word here in its widest meaning. It covers, on the one side, the mental dispositions which may still be quite undeveloped and which may unfold only under the influence of special conditions in the surroundings; but, on the other side, it covers the habitual traits of the personality, the features of the individual temperament and character, of the intelligence and of the ability, of the collected knowledge and of the acquired experience. All variations of will and feeling, of perception and thought, of attention and emotion, of memory and imagination, are included here. From a purely psychological standpoint, quite incomparable contents and functions and dispositions of the personality are thus thrown together, but in practical life we are accustomed to proceed after this fashion: if a man applies for a position, he is considered with regard to the totality of his qualities, and at first nobody cares whether the particular feature is inherited or acquired, whether it is an individual chance variation or whether it is common to a larger group, perhaps to all members of a certain nationality or race. We simply start from the clear fact that the personalities which enter into the world of affairs present an unlimited manifoldness of talents and abilities and functions of the mind. From this manifoldness, it necessarily follows that some are more, some less, fit for the particular economic task. In view of the far-reaching division of labor in our modern economic life, it is impossible to avoid the question how we can select the fit personalities and reject the unfit ones.

How has modern society prepared itself to settle this social demand? In case that certain knowledge is indispensable for the work or that technical abilities must have been acquired, the vocation is surrounded by examinations. This is true of the lower as well as of the higher activities. The direct examination is everywhere supplemented by testimonials covering the previous achievements, by certificates referring to the previous education, and in frequent cases by the endeavor to gain a personal impression from the applicant. But if we take all this together, the total result remains a social machinery by which perhaps the elimination of the entirely unfit can be secured. But no one could speak of a really satisfactory adaptation of the manifold personalities to the economic vocational tasks. All those examinations and tests and certificates refer essentially to what can be learned from without, and not to the true qualities of the mind and the deeper traits. The so-called impressions, too, are determined by the most secondary and external factors. Society relies instinctively on the hope that the natural wishes and interests will push every one to the place for which his dispositions, talents, and psychophysical gifts prepare him.

In reality this confidence is entirely unfounded. A threefold difficulty exists. In the first place, young people know very little about themselves and their abilities. When the day comes on which they discover their real strong points and their weaknesses, it is often too late. They have usually been drawn into the current of a particular vocation, and have given too much energy to the preparation for a specific achievement to change the whole life-plan once more. The entire scheme of education gives to the individual little chance to find himself. A mere interest for one or another subject in school is influenced by many accidental circumstances, by the personality of the teacher or the methods of instruction, by suggestions of the surroundings and by home traditions, and accordingly even such a preference gives rather a slight final indication of the individual mental qualities. Moreover, such mere inclinations and interests cannot determine the true psychological fitness for a vocation. To choose a crude illustration, a boy may think with passion of the vocation of a sailor, and yet may be entirely unfit for it, because his mind lacks the ability to discriminate red and green. He himself may never have discovered that he is color-blind, but when he is ready to turn to the sailor's calling, the examination of his color-sensitiveness which is demanded may have shown the disturbing mental deficiency. Similar defects may exist in a boy's attention or memory, judgment or feeling, thought or imagination, suggestibility or emotion, and they may remain just as undiscovered as the defect of color-blindness, which is characteristic of four per cent of the male population. All such deficiencies may be dangerous in particular callings. But while the vocation of the ship officer is fortunately protected nowadays by such a special psychological examination, most other vocations are unguarded against the entrance of the mentally unfit individuals.

As the boys and girls grow up without recognizing their psychical weaknesses, the exceptional strength of one or another mental function too often remains unnoticed by them as well. They may find out when they are favored with a special talent for art or music or scholarship, but they hardly ever know that their attention, or their memory, or their will, or their intellectual apprehension, or their sensory perceptions, are unusually developed in a particular direction; yet such an exceptional mental disposition might be the cause of special success in certain vocations. But we may abstract from the extremes of abnormal deficiency and abnormal overdevelopment in particular functions. Between them we find the broad region of the average minds with their numberless variations, and these variations are usually quite unknown to their possessors. It is often surprising to see how the most manifest differences of psychical organization remain unnoticed by the individuals themselves. Men with a pronounced visual type of memory and men with a marked acoustical type may live together without the slightest idea that their contents of consciousness are fundamentally different from each other. Neither the children nor their parents nor their teachers burden themselves with the careful analysis of such actual mental qualities when the choice of a vocation is before them. They know that a boy who is completely unmusical must not become a musician, and that the child who cannot draw at all must not become a painter, just as on physical grounds a boy with very weak muscles is not fit to become a blacksmith. But as soon as the subtler differentiation is needed, the judgment of all concerned seems helpless and the physical characteristics remain disregarded.

A further reason for the lack of adaptation, and surely a most important one, lies in the fact that the individual usually knows only the most external conditions of the vocations from which he chooses. The most essential requisite for a truly perfect adaptation, namely, a real analysis of the vocational demands with reference to the desirable personal qualities, is so far not in existence. The young people generally see some superficial traits of the careers which seem to stand open, and, besides, perhaps they notice the great rewards of the most successful. The inner labor, the inner values, and the inner difficulties and frictions are too often unknown to those who decide for a vocation, and they are unable to correlate those essential factors of the life-calling with all that nature by inheritance, and society by surroundings and training, have planted and developed in their minds.

In addition to this ignorance as to one's own mental disposition and to the lack of understanding of the true mental requirements of the various social tasks comes finally the abundance of trivial chances which become decisive in the choice of a vocation. Vocation and marriage are the two most consequential decisions in life. In the selection of a husband or a wife, too, the decision is very frequently made dependent upon the most superficial and trivial motives. Yet the social philosopher may content himself with the belief that even in the fugitive love desire a deeper instinct of nature is expressed, which may at least serve the biological tasks of married life. In the choice of a vocation, even such a belief in a biological instinct is impossible. The choice of a vocation, determined by fugitive whims and chance fancies, by mere imitation, by a hope for quick earnings, by irresponsible recommendation, or by mere laziness, has no internal reason or excuse. Illusory ideas as to the prospects of a career, moreover, often falsify the whole vista; and if we consider all this, we can hardly be surprised that our total result is in many respects hardly better than if everything were left entirely to accident. Even on the height of a mental training to the end of adolescence, we see how the college graduates are too often led by accidental motives to the decision whether they shall become lawyers or physicians or business men, but this superficiality of choice of course appears much more strongly where the lifework is to be built upon the basis of a mere elementary or high school education.

The final result corresponds exactly to these conditions. Everywhere, in all countries and in all vocations, but especially in the economic careers, we hear the complaint that there is lack of really good men. Everywhere places are waiting for the right man, while at the same time we find everywhere an oversupply of mediocre aspirants. This, however, does not in the least imply that there really are not enough personalities who might be perfectly fit even for the highest demands of the vocations; it means only that as a matter of course the result in the filling of positions cannot be satisfactory, if the placing of the individuals is carried on without serious regard for the personal mental qualities. The complaint that there is lack of fit human material would probably never entirely disappear, as with a better adjustment of the material, the demands would steadily increase; but it could at least be predicted with high probability that this lack of really fit material would not be felt so keenly everywhere if the really decisive factor for the adjustment of personality and vocation, namely, the dispositions of the mind, were not so carelessly ignored.
