Instincts of the Herd in Peace and War

by W. Trotter

Manifestations relatively more simple are shown in the dislike of being conspicuous, in shyness and in stage fright. It is, however, sensitiveness to the behaviour of the herd which has the most important effects upon the structure of the mind of the gregarious animal. This sensitiveness is closely associated with the suggestibility of the gregarious animal, and therefore with that of man. The effect of it will clearly be to make acceptable those suggestions which come from the herd, and those only. It is of especial importance to note that this suggestibility is not general, and that it is only herd suggestions which are rendered acceptable by the action of instinct. Man is, for example, notoriously insensitive to the suggestions of experience. The history of what is rather grandiosely called human progress everywhere illustrates this. If we look back upon the development of some such thing as the steam-engine, we cannot fail to be struck by the extreme obviousness of each advance, and how {33} obstinately it was refused assimilation until the machine almost invented itself.

Again, of two suggestions, that which the more perfectly embodies the voice of the herd is the more acceptable. The chances an affirmation has of being accepted could therefore be most satisfactorily expressed in terms of the bulk of the herd by which it is backed.

It follows from the foregoing that anything which dissociates a suggestion from the herd will tend to ensure such a suggestion being rejected. For example, an imperious command from an individual known to be without authority is necessarily disregarded, whereas the same person making the same suggestion in an indirect way so as to link it up with the voice of the herd will meet with success.

It is unfortunate that in discussing these facts it has been necessary to use the word “suggestibility,” which has so thorough an implication of the abnormal. If the biological explanation of suggestibility here set forth be accepted, the latter must necessarily be a normal quality of the human mind. To believe must be an ineradicable natural bias of man, or in other words an affirmation, positive or negative, is more readily accepted than rejected, unless its source is definitely dissociated from the herd. Man is not, therefore, suggestible by fits and starts, not merely in panics and in mobs, under hypnosis, and so forth, but always, everywhere, and under any circumstances. The capricious way in which man reacts to different suggestions has been attributed to variations in his suggestibility. This in the opinion of the present writer is an incorrect interpretation of the facts which are more satisfactorily explained by regarding the variations as due to the differing extent to which suggestions are identified with the voice of the herd.

Man’s resistiveness to certain suggestions, and {34} especially to experience, as is seen so well in his attitude to the new, becomes therefore but another evidence of his suggestibility, since the new has always to encounter the opposition of herd tradition.

The apparent diminution in direct suggestibility with advancing years, such as was demonstrated in children by Binet, is in the case of the adult familiar to all, and is there usually regarded as evidence of a gradually advancing organic change in the brain. It can be regarded, at least plausibly, as being due to the fact that increase of years must bring an increase in the accumulations of herd suggestion, and so tend progressively to fix opinion.

In the early days of the human race, the appearance of the faculty of speech must have led to an immediate increase in the extent to which the decrees of the herd could be promulgated, and the field to which they applied. Now the desire for certitude is one of profound depth in the human mind, and possibly a necessary property of any mind, and it is very plausible to suppose that it led in these early days to the whole field of life being covered by pronouncements backed by the instinctive sanction of the herd. The life of the individual would be completely surrounded by sanctions of the most tremendous kind. He would know what he might and might not do, and what would happen if he disobeyed. It would be immaterial if experience confirmed these beliefs or not, because it would have incomparably less weight than the voice of the herd. Such a period is the only trace perceptible by the biologist of the Golden Age fabled by the poet, when things happened as they ought, and hard facts had not begun to vex the soul of man. In some such condition we still find the Central Australian native. His whole life, to its minutest detail, is ordained for him by the voice of the herd, and he must not, under the most dreadful {35} sanctions, step outside its elaborate order. It does not matter to him that an infringement of the code under his very eyes is not followed by judgment, for with tribal suggestion so compactly organized, such cases are in fact no difficulty, and do not trouble his belief, just as in more civilized countries apparent instances of malignity in the reigning deity are not found to be inconsistent with his benevolence.

Such must everywhere have been primitive human conditions, and upon them reason intrudes as an alien and hostile power, disturbing the perfection of life, and causing an unending series of conflicts.

Experience, as is shown by the whole history of man, is met by resistance because it invariably encounters decisions based upon instinctive belief, and nowhere is this fact more clearly to be seen than in the way in which the progress of science has been made.

In matters that really interest him, man cannot support the suspense of judgment which science so often has to enjoin. He is too anxious to feel certain to have time to know. So that we see of the sciences, mathematics appearing first, then astronomy, then physics, then chemistry, then biology, then psychology, then sociology—but always the new field was grudged to the new method, and we still have the denial to sociology of the name of science. Nowadays, matters of national defence, of politics, of religion, are still too important for knowledge, and remain subjects for certitude; that is to say, in them we still prefer the comfort of instinctive belief, because we have not learnt adequately to value the capacity to foretell.
