CHAPTER X

INDIVIDUALITY AND EDUCATION

I. THE VALUES OF INDIVIDUALITY

If we try to imagine what the world would be like if there were absolute

uniformity among human beings, we realize anew the precious worth of

individuality. It is marvelous that each one of us is unique. In all the

generations there has never been another just like anyone, and there

will never be exactly his like again. Each is, strictly speaking,

irreplaceable.

By this inexhaustible diversity of mind and body life is faceted, and

gives off sparkle instead of dullness. So far from being irritated by

the idiosyncracies of our fellows, we ought to cherish their variety as

a thing that makes life worth living. Instead of striving to force all

children to learn the same things, at the same time, in the same way,

because that would be cheap and convenient, we ought to foster

individuality in its socially valuable aspects, so that the charm of

human contact may be increased. To the connoisseur of human nature, the

suggestion that all children be reduced to similarity is as dreadful as

the suggestion to the connoisseur of art that all pictures and intaglios

be turned out identical, by a uniform factory process.

Nor is the value of individuality limited to the æsthetics of

personality, and to social intercourse. The economic peculiarities of

the world, as we have it, permit the exercise of abilities in great

variety. Organized society needs and will use capacity of all degrees,

from that of a man who can load sand on a carrier, and be satisfied

thereby, to that of the man who can with satisfaction work out a new

theory of inflammation, or construct a drama to interpret existence

anew.

Failure to know the facts concerning the distribution of mental traits,

the organization of intellect, and the laws of heredity and variation,

leads to much wasted effort on the part of all who deal by profession

with people. The most frequent error is that of demanding that others

adopt one’s own religious beliefs, standard of living, reaction time, or

politics—usually with the idea that they will be greatly benefited

thereby. Another common error of theory is that general happiness would

be increased if some force could be established great enough to hold all

down to the same plane of work, leisure, and reward. In education it has

been assumed that justice would be well served by prescribing the same

curriculum, at the same rate, at the same time, for every child.

If the uniformity of thought and action, to which these theories and

practices tend, could be secured, the result would be deadening. Such

uniformity cannot, however, be achieved, because of the biological

forces of heredity and variation. The formulæ governing the interplay of

these forces are little known, and they therefore lie outside of human

control.

Many thinkers believe that nothing would be lost and much be gained for

human welfare, by cutting off the variants who fall low in intellect and

stability, and by increasing the number of those who fall highest, on

the curve of distribution. However, it is possible to take, and perhaps

to defend, the view that this would be meddlesome rather than helpful.

Civilization becomes complex through the discoveries and inventions of

superior deviates. It was they who invented wheel and lever, clock and

calendar, court and statute book. They discovered the use of

electricity, gravity, and steam. When moral life and industrial life

become very complicated, great numbers of men are unable to meet the

situations devised, and perish mentally, morally, and physically. Law

may become so intricate that only the steadiest can suffer its

restrictions. Mechanical and chemical contrivances may grow so numerous

and complex that typical human nature cannot cope with them. Would it be

better, then, to end invention at its source, by eliminating superior

deviates? Or would mankind thereby lose other gifts, wholly benign for

all, which only the superior deviate can bestow? In the absence of the

highly endowed, would there not be a return to barbarism? And, if so,

would the greatest good of the greatest number be thus promoted? Or

should the welfare of the majority give way as a social ideal to the

welfare of the best—the most capable, the most upright, the most

enduring? Is it possible to evolve a social order in which the greatest

good of all can be well served, since biological inequalities are so

very great? These are questions for social and educational philosophy.

Men of science labor to acquire the knowledge that would give power to

alter, at will, the shape of the curve of distribution for mental

capacities. Such knowledge might work more changes in the world than

have been wrought by knowledge of chemical formulæ or of electricity,

but its right use would call for a wisdom and philosophical foresight

which men at present probably do not have. The conditions and the

theories that confront us in education call on us at present, as a

matter of fact, to provide for the whole enormous range of capacities,

general and special.

II. COMPULSORY EDUCATION

It is useful to recall that for centuries after mankind reached a point

where prolonged formal education was available, attendance upon

instruction was voluntary. Those who wished to learn what could be

taught of the arts and sciences, hired tutors. It is true that the

public ceremonies may, perhaps, be considered to have represented

compulsory education, even in primitive times. However, education in the

sense of several years of devotion to learning what men have previously

done, thought, and devised, was formerly a private matter. The educated,

who could communicate by writing, calculate in large numbers, see the

present to some extent in the light of the past, and engage in even more

complicated intellectual work, formed a small and highly selected group.

They were individuals who loved learning, and their median IQ was

doubtless far above 100.

As the white peoples of the earth, in parts of Europe and America,

accumulated wealth, and more and more of those who cared to do so could

buy education, political power began to be decentralized. Generous men

of high intelligence conceived the idea that government should be

representative. Political democracy with manhood suffrage was

established in the United States. It was then seen that political

democracy cannot be sustained on the basis of private education, and

public money was appropriated to establish public schools.

Merely to establish free schools did not, however, solve the problem of

education for a democracy. The leaders of thought and action found that

not only must opportunity be provided, but many must be forced to take

advantage of it. Compulsory education laws were therefore passed in many

of our states, and they stand upon their statute books to-day. Truant

officers became a part of the regular school staff, their duty being to

apprehend all children between statutory ages, and bring them forcibly

to school. The City of New York, for instance, now supports 308 truant

officers, who are constantly kept busy by future citizens who wish to

avoid education.

Why do they wish to avoid education? The reasons are various. Some of

them avoid school because they have not enough clothing to wear; some

because their parents need their earnings; some because they are ill;

some because they are temperamentally unsuited to school discipline. The

most important single cause of truancy is, however, that the curriculum

does not provide for individual differences.

The curriculum upon which all children are now required by law to

attend, is that which was formulated when only a few selected children

were educated. Our schools are reading schools, and they teach abstract

subject matter to a very great extent, much of which has no tangible

relation to the life of many children. Children of IQ over 120 take

pleasure in the abstract subject matter of grammar, mathematics,

geography, and history. Children of IQ under 80 are made miserable

thereby.

Not only is the curriculum not adapted to individual differences in

general intelligence, but it is far less adapted to individual

differences in special defects and aptitudes. The child who can never

learn to sing is compelled nevertheless to pursue singing, even after

school hours. The child who cannot learn reading by the method generally

used is still treated by that method and no other. The schools were

established with an undifferentiated curriculum, which they have tried

to force upon intellects of an enormous range of diversity. Their

purpose, so benign, has resulted in extraordinary cruelties and wastes.

III. THE IMPORTANCE OF GENERAL INTELLIGENCE FOR SCHOOL PROGRESS

If we examine mentally the large numbers of retardates in any public

school where attendance is compulsory, we find that by far the majority

of them are inferior in general intelligence. A child of superior

general intelligence (IQ) is seldom found among retardates. Of children

of 120 IQ and over, Terman reports that they are almost invariably at

least up to grade. Whatever the vicissitudes of fate—illness, absence,

special disability—a child of superior general capacity manages to hold

his own, at least.

It is not true, however, that the superior child is allowed, under the

undifferentiated curriculum, to make full use of his power. He is

compelled to slow down to the typical progress of his group, and to use

only a portion of his capacity for learning. It is rare to find a

superior child who is doing “a full day’s work” in school, because the

tasks assigned do not call for maximum effort. Superior children could

easily do much more than is allowed.

General intelligence is, then, the single most important factor for

school progress. The same may be said of progress in vocational careers.

The life success of a human being may be said to depend upon general

intelligence, character, health, and opportunity (including the factor

of sex). If any of these factors is reduced to zero, so that the

individual is totally lacking in intelligence, character, health, or

opportunity there can be no achievement. The order of importance of the

various factors is probably that in which they have been mentioned, with

general intelligence certainly at the top of the list. Intelligence may

create character, opportunity, and even health, but none of these can

create intelligence.

IV. SPECIAL ABILITIES AND DISABILITIES AS DETERMINANTS OF SCHOOL

PROGRESS

As before stated in these pages, no census has ever been taken of

special aptitudes and defects, in the functions which we have been

discussing, and which are important for progress through the elementary

school. No one can tell whether any have been advanced on the basis of a

special gift. No one can say how many children are retarded, because of

a specialized disability, though we know from reports rendered, that

some pupils become retarded in school status through special failure in

one or two respects.

The children described under the topics of special retardation in

reading and in arithmetic, in this volume, are illustrative of the way

in which specialized defect contributes to retardation in school status.

Without passable mastery of these “tool” subjects a child cannot proceed

through the elementary school. His progress is halted, much as it would

be if he were deficient in general intelligence.

It is quite possible, on the other hand, that children may be

occasionally overrated as to intellect by teachers, who are deceived by

conspicuous talent in a special function. Coy, who studied for two years

a class of highly intelligent children in Columbus, has given an account

of a boy who was thus overrated. When the children were being selected

for the special class described, this boy was sent by his teacher to

join the group. She considered that he must be “very bright,” “since he

could draw cartoons, play the ukelele, and sing.” He was said by the art

teacher to have more ability than any other child in the building. He

was retained in the special class by the investigator, but he was not

able to do good work there. His IQ on three annual testings stood as

114, 119, and 120. (The other children in the group possessed general

intelligence clustering about an IQ of approximately 135.) This boy

surpassed the others in music, acting, and drawing, but “his ability to

reason was far below the class level,” and he could not compete

successfully in general intellectual work. His teachers had been misled

by his special gifts to recommend him as a child of surpassing

intellect.

V. EXPERIMENTAL ATTEMPTS TO INDIVIDUALIZE EDUCATION

Official administrative recognition of individual differences among

public school pupils began with the extremely stupid, whom we call

feeble-minded. This was natural, because the feeble-minded are incapable

of even approximately normal progress, and this, added to their tendency

to become disciplinary problems, renders them an intolerable burden to

teachers in the regular grades.

As long ago as 1872 we find that attention was called to the

“pedagogical misfits,” in proceedings at professional teachers’ meetings

in the United States. By 1890 the city of Cleveland had established two

special classes for children presenting particular difficulties of

discipline. Special classes for extremely dull children (the

feeble-minded) have passed the stage of experiment. They are now an

accepted part of the school system of many cities in this country, and a

few state departments of education have undertaken to establish such

special classes for districts not so favorably situated as cities are.

The relative money cost of thus educating the most stupid children

produced in our population is great, and the returns upon the investment

are uncertain. We need careful studies of the cost of educating the

dull, as compared with the cost of educating the superior, in the light

of the returns from education, both to the public and to the individuals

taught. The complexity of such study calls for much patience and

ingenuity.

Special classes for children of very superior general intelligence, who

are as far above the average as the feeble-minded are below, are at

present much discussed by American educators. Such classes have actually

been established in a few school systems. These are still considered to

be experimental, but it surely will not be very long before official

administrative recognition will be widely given to the needs of pupils

whose natural rate of progress is over twice as rapid as that of the

average child. Abroad, Germany has already undertaken education for

gifted children as a special project of the public schools, in

recognition, no doubt, of the extent to which national rehabilitation

will be dependent on the training of the able. Contrary to pre-war

policy, German educators are now seeking, by the method of mental tests,

for superior mental endowment regardless of social-economic status, and

even to some extent regardless of sex.

In general it is true that the provisions in the United States are for

deviates so extreme in all capacities that their maladjustment to

typical procedure creates a troublesome school problem on the one hand,

and on the other a burden to the conscience of those who administer

education. Classroom teachers demand that special attention be given to

those who are chronically unpromotable and out of order, while

educational psychologists insist upon the waste of ability that ensues

from allowing gifted children to idle through the curriculum. For

deviates of less degree there is not much provision. A few cities, of

which Oakland, California, may be mentioned as an outstanding example,

have adopted a three-rates-of-progress system, in which the children of

typical ability (the great majority) proceed at a median rate, the

lowest quartile (exclusive of the very lowest percentile) proceeding

more slowly, and the highest quartile more rapidly. The system provides

a flexibility far in advance of the ordinary one-rate-of-progress

system, allowing for individual differences in general intelligence.

Little attention has been given as yet to the matter of individualizing

public education for children who show special talents or defects. Some

years ago the superintendent of schools in Munich requested the teachers

of certain grades throughout the city, to ask each child to draw two

sketches: one from a model, and the other a free sketch. These were

sorted for the purpose of finding exceptional talent in drawing. A

certain per cent of the children showing this special gift were sought

out and encouraged. Particular attention was given to the development of

their talents.

Similar instances of official attempts to gauge and foster special

talents are extremely rare. The experiment at Winnetka, Illinois, is of

this order. In Winnetka there is a flexible promotion system, wherein

pupils “pass” in a subject whenever they have completed the work

therein. A pupil may be in different grades in different subjects. His

whole school career need not be jeopardized by a single weakness, and if

he has a special strength he is permitted to develop it as original

nature would dictate.

At first thought it might seem that a public school system would be

thrown into confusion by such a scheme. In Winnetka there are thirty to

thirty-five pupils in a classroom. How can programs be arranged to suit

the needs of deviating children, without much extra equipment?

Here it is necessary to recall that the majority of these children are

_typical_. The middle 50 per cent of all children born deviate but

slightly from the type of the race, in all their mental functions. They

do not call for special adjustments. On either side of these, deviating

more widely toward less and greater, run the remainder of the children,

in very rapidly decreasing frequencies. Those who need a very wide

latitude in school organization constitute possibly 20 per cent of all,

the highest 10 per cent, and the lowest 10 per cent, in general or

special capacity. The problem does not seem so vast, when we recall the

shape of the curve of distribution; and the comparative infrequency of

extremely unusual children.

VI. THE COST OF FOSTERING INDIVIDUALITY

The cost of individualizing education acts as a deterrent, even when the

desirability is fully recognized. Compulsory education for all the

children of all the people is expensive. A nation must be wealthy in

order to carry it through. To maintain every child born into the social

order for fourteen to sixteen years without earnings, and to pay from

public taxation for his education for eight to ten or more of those

years, is an enterprise upon which few societies of any time have

ventured. Nevertheless, if democracy is to survive, and especially if it

is to improve, as a form of government, universal education on a large

scale is basic. Self-government, in the highly complicated environment

which has been evolved, depends on literacy and other knowledge,

requiring long instruction, even for youth of average ability.

What then of the great numbers of those who deviate in various degrees

below the average in capacity for learning? The social order needs and

will utilize their services. The economics of their presence in the

republic is not a much more difficult problem than under other forms of

government. It is the politics of their presence that causes concern

under a democracy; for they are enfranchised, yet without learning they

are political dependents. They stand at the mercy of any catch word

tossed at them, with results which have raised on every hand an earnest

searching of democracy.

For example, this question has been raised: Is it possible for education

to prepare the lower half of the distribution curve for self-government?

Considering recent discoveries as to the mental capacity which

characterizes the lower half of the population when adult, is it

possible that education will ever be able to nullify the charlatan

influence of demagogues, whose appeal is to prejudice and cupidity?

These questions remain unanswered. In the meantime the great experiment

of compulsory education is under way. The expense of it is kept down by

teaching the children in large groups of thirty to fifty or over, the

same lessons, in the same way, at the same time.

What would be the actual money cost of providing for individual

differences in capacities, general and special? Few data to answer this

question have been furnished. In Winnetka the cost of education is

reported as not increased. This condition is doubtless exceptional. As

previously stated, the money cost of individualizing education for the

feeble-minded has been considerable. We have the figures from

Cincinnati, and we derive from them that the cost of educating a

feeble-minded child (one falling into the lowest one or two per cent in

the distribution of general intelligence) in a special class, is over

twice as great per annum as is the cost of educating an average child in

the regular grades. For a feeble-minded child in a special class in

Cincinnati, during the year 1917 to 1918, the money cost per annum was

$83, while for a typical child in the regular grades it was $35.

The increased cost results from the fact that when education is

individualized, the number of pupils occupying a room and taught by a

teacher is about fifteen, instead of the regular number of thirty to

fifty. If, roughly, 20 per cent of all pupils deviate from the typical

so extremely as to require a considerable amount of individual

instruction for their welfare, it is difficult to see how they may be

well served without a considerable increase in the money cost of

education.

Can the public afford to pay more than it now does? Investigations to

answer this question are under way on a large scale. We need to know

what our country can now pay, in order that we as educators may not

commit the folly on the one hand of urging unwarrantable expenditure,

nor on the other hand of failing to ask the appropriation of all that

can be spared for the development of individual capacity in the nation’s

children.

VII. THE PROBABLE REWARDS OF INDIVIDUALIZING EDUCATION

Even the money returns from scientifically differentiated education

would probably be great, aside from the increase in children’s

happiness, in teachers’ enjoyment, and in adults’ satisfaction. The

tangible values of individualized training might be nearly as great as

its intangible values.

When we reflect closely upon the source of wealth, we see that it comes

from the attack of intellect upon the environment. Apes have no wealth.

Man has wealth only in so far as he acts upon selective thinking in

regard to his environment. A society gains wealth only in so far as it

permits and encourages the use of innate capacities for attack upon the

environment, which lie unequally distributed throughout the juvenile

population. Any theory of wealth that fails to ground itself upon this

fact will but destroy those who seek to practice it.

No nation has ever yet shown what the full reward might be of adapting

education to individual differences. Such a demonstration has been

impossible hitherto, if for no other reason than that there was no known

method of gauging children’s abilities scientifically.

In the older social orders, where education was or is caste-bound, it is

highly probable that on the whole education was and is more fairly

adapted to individual differences than it is with us. Those barbarians

who had much capacity for abstract thinking achieved by trial and

success high-caste status, of which they ultimately became conscious.

The aristocracy of older countries was not established by forces outside

of human nature. The nobles were in the first place those who rose to

power because they were stronger, more enduring, and more capable of

thinking than average men. Caste grew out of human nature itself. The

majority of the nobles’ children were capable by heredity of abstract

thinking, and of acquiring the education, which came finally through

centuries to be provided for them. The majority of those who failed to

achieve high-caste status before it became recognized as such were

doubtless chiefly individuals who produced descendants, on the average

ill adapted to profit from the kind of education established for the

children of the higher castes.

In Great Britain, for example, where social organization was and is

frankly based in theory and practice on caste (upper-caste status being,

however, constantly kept open to adults of unusual achievement), Burt

found that boys of upper-caste family, attending an exclusive high-class

school, surpassed in all respects, in mental tests, sons of middle-class

parents, of equal age, attending common schools. It is necessary, though

outrageous to our prejudices, to face the fact that, in our own country

(where caste is despised in theory and to some extent in practice), the

median capacity of pupils in expensive private schools is well above the

average of the juvenile population at large.

Caste-bound education in older civilizations recognizes innate

individual differences to a considerable extent. Its injustice is that

it does not recognize them completely. Caste takes account of individual

differences due to heredity, but it does not regard those due to

variation. Caste neglects to provide for the overlapping which occurs

among the children of parents of different achievement levels. In a

society founded formally on caste, there is no way provided for the

appropriate education of gifted variants who occur in the lower castes,

and for those of inferior ability born into the higher castes.

Artificial barriers to natural achievement have arisen, because the

consciousness of superior status was accompanied by jealousy of it as

well. Revolt against this injustice to the minority (not recognized,

however, as minority by the rebels) led to the opposite injustice, which

we see practiced in the schools of our own democracy.

In the United States the theory was adopted that all men are created

equal. All children must, therefore, be required to take the same

education. Such a system violates individuality even more painfully and

wastefully than the despised caste system of the older countries does.

As scientific psychology improves the methods of testing for individual

differences in children, it will become possible to educate each one

according to his capacity for learning. It will be possible to conserve

and develop the special aptitudes of every child, regardless of race,

sex, or circumstance. The humiliation and despair of chronic failure at

prescribed tasks unsuited to capacity may be spared every child.

Thus we come again to consider tests of innate educability in _The

Republic_: “We must watch them from their youth upwards, and make them

perform actions in which they are most likely to forget or to be

deceived, and he who remembers and is not deceived is to be selected.”

That will be the way.

Footnote 1:

ρ = 1 − 6ξ_d_^2/_n_(_n_^2 − 1)

Resemblance equals one minus six times the sum of the differences (in

rank) squared, over the number (of cases) times the number (of cases)

squared, minus one.

Footnote 2:

ρ = 1 − 6ξ_d_^2/_n_(_n_^2 − 1) Formula explained, opposite page.

Footnote 3:

Thompson has recently shown that a coefficient of zero does not

necessarily mean absence of relationship between two factors. There

might be a strong influence making for negative correlation, and at

the same time an equally strong influence making for positive

correlation, which might, by just counterbalancing each other, produce

a spurious effect of no connection at all, namely, a coefficient of

0.00.

Footnote 4:

A curious case of negative correlation between cancellation and other

tests has been reported by McCall (see references).

Footnote 5:

“Insanity” and “dementia” seem to be synonymous, as used by Hart and

Spearman. But in American texts “dementia” is limited to mean

intellectual deterioration.

Footnote 6:

Because of the probabilities in die-casting, every single value for

red would have the same median value among the throws of yellow, which

turn up in connection with it, if enough throws are made. This is not

what happens in measuring mental traits. For any single value, high or

low, in one function, the median of repeated measures in the other

function is very different, for most traits, from the median for other

values.

Footnote 7:

For explanation of technical terms see McCall’s _How to Measure in

Education_.

Footnote 8:

This suggestion originated with a colleague of the present writer, who

is working upon allied problems.

Footnote 9:

See Reference to Ladd and Woodworth.

Footnote 10:

It must be remembered that children and adults of almost any birthday

age may be at this general intelligence level.

Footnote 11:

If alternates are counted instead of the four tests which directly

involve reading or spelling, these IQ’s become 88, 85, 87,

respectively.

Footnote 12:

For all practical purposes, IQ’s differing from each other by not more

than 5 points are equal.

Footnote 13:

Fildes’ subjects ranged in birthday age from 9 to 16 years. In

criticism it should be stated that correlation between IQ and ability

to read cannot be clearly interpreted unless an array of birthday ages

is given in conjunction. Fildes does not give such an array.

Footnote 14:

The substance of discussion under this topic is reprinted by courtesy

of the _Teachers College Record_, from the issue of that journal for

March, 1919.

Footnote 15:

Quoted by permission of the Atlantic Monthly Press.

Footnote 16:

Bidder died at 72.

Footnote 17:

The writer is indebted to Miss Mabel R. Goodlander, R’s teacher in the

fourth grade, for this report.
