brings out the fact that lamentably few persons are accustomed to be, or can readily be, measured. It has been a great drawback to the advance of Scientific Management that the moment a measurer of any kind is put on the work, either a device to measure output or a man to measure or to time reactions, motions, or output, the majority of the workers become suspicious. Being unaccustomed to being measured, they think, as is usually the case with things to which we are unaccustomed, that there is something harmful to them in it. This feeling makes necessary much explanation which in reality should not be needed.
The remedy for this condition is a proper training in youth. A boy brought up with the fundamental idea of the importance of measurement to all modern science, for all progress, accustomed to being measured, understanding the "why" of the measuring, and the results from it, will not hesitate or object, when he comes to the work, to being measured in order that he may be put where it is best for himself, as well as for the work, that he be put.
The importance of human measurement to vocational guidance and to the training of the young for life work has never been properly realized. Few people understand the importance of psychological experiment as a factor in scientific vocational guidance. For this alone, it will probably in time be a general custom to record and keep as close track as possible of the psychological measurements of the child during the period of education, vocational guidance and apprenticeship. Not only this, but he also should be
accustomed to being measured, physically and psychologically, from his first years, just as he is now accustomed to being weighed.
The child should be taught to measure himself, his faculties, his reactions, his capabilities as compared with his former self and as compared with the capabilities of others. It is most important that the child should form a habit not only of measuring, but of being measured.
Motion Study and Time Study Are the Method of Measurement Under Scientific Management. — Under Scientific Management, much measuring is done by motion study and time study, which measure the relative efficiency of various men, of various methods, or of various kinds of equipment, surroundings, tools, etc. Their most important use is as measuring devices of the men. They have great psychological value in that they are founded on the "square deal" and the men know this from the start. Being operated under laws, they are used the same way on all sorts of work and on all men. As soon as the men really understand this fact, and realize
1. that the results are applied to all men equally;
2. that all get an ample compensation for what they do;
3. that under them general welfare is considered; the objections to such study will vanish.
Motion Study Is Determining Methods of Least Waste. — Motion Study is the dividing of the elements of the work into the most fundamental subdivisions possible; studying these fundamental units separately and in relation to one another; and from
