Ingroups and Outgroups and Sir Arthur Keith – Adventures in the Bowdlerization of History

There is no more important aspect of human nature than our tendency to perceive others in terms of ingroups and outgroups. Without an awareness of its existence and its power it is impossible to understand either out history or many of the critical events that are happening around us today. A trait that probably existed in our ancestors millions of years ago, it evolved because it promoted our survival when our environment and way of life were radically different from what they are now. In the context of current human technologies and societies, it often appears to have become wildly dysfunctional. We can distinguish ingroup from outgroup based on the subtlest of differences. That worked fine when we all lived in small groups of hunter-gatherers. The outgroup was always just the next group over. Today the same mental equipment for identifying the outgroup has resulted in endless confusion and, in many cases, disaster. The only way out lies in self-understanding, but as a species we exhibit an incorrigible resistance to knowing ourselves.

In my last post I commented on the foibles of an ingroup of intellectuals whose “territory” was defined by ideology. I’m sure they all believed their behavior was entirely rational, but they had no clue what was going on as they reacted to a “turncoat” and “heretic” in the same way that ingroups have done for eons. Had they read a seminal book by Sir Arthur Keith entitled A New Theory of Human Evolution, they might have had at least an inkling about the real motivation of their behavior. Published in 1948, the book was of critical importance, not just because it addressed the question of ingroups and outgroups, but because of Keith’s sure feel for the aspects of human behavior that really matter, and for his forthright and undaunted insistence on the existence and importance of innate human nature. He was certainly not infallible. What scientist is? He believed the Piltdown skull was real until it was finally proved a hoax just before he died. Some of what he had to say about human behavior has stood the test of time and some hasn’t. However, his hypotheses about ingroups and outgroups definitely belong in the former category, along with many others. There is no question that they were closer to the truth than the Blank Slate dogmas that already served as holy writ for most of the so-called behavioral scientists of the day.

Today there are few original copies of his book around, although some are offered at Amazon as I write this. However, it is available online at, and reprints are available at and elsewhere. It is a must read if you interested in human behavior, and even more so if you are interested in the history of the behavioral sciences in general and the Blank Slate in particular. Unfortunately, most of the accounts of that history that have appeared in the last 50 years or so are largely fairy tales, concocted either to deny or “embellish” the reality that the Blank Slate was the greatest scientific catastrophe of all time. If you want to know what really happened, there is no alternative to consulting the source material yourself.  One of the biggest fairy tales is that the man who played the greatest single role in demolishing the Blank Slate, Robert Ardrey, was “totally and utterly wrong.” In fact, Ardrey was “totally and utterly right” about the main theme of all his books; that human nature is both real and important. He insisted on that truth in the teeth of the Blank Slate lies that had been swallowed by virtually every “behavioral scientist” of his day.

Ardrey had an uncanny ability to ferret out scientists whose work actually did matter. Sir Arthur Keith was no exception. What he had to say about Keith and his take on ingroup/outgroup behavior was far more eloquent than anything I could add. For example,

In his last two books, Essays on Human Evolution in 1946 and A New Theory of Human Evolution in 1948, Keith took the final, remorseless step which his thinking had made inevitable. Conscience, he affirmed is simply that human mechanism dictating allegiance to the dual code. Those who assert that conscience is inborn are therefore correct. But just how far does conscience compel our actions in such an ultimate direction as that of the brotherhood of man? Not far. Conscience is the instrument of the group.

Human nature has a dual constitution; to hate as well as to love are parts of it; and conscience may enforce hate as a duty just as it enforces the duty of love. Conscience has a two-fold role in the soldier: it is his duty to save and protect his own people and equally his duty to destroy their enemies… Thus, conscience serves both codes of group behavior: it gives sanction to practices of the code of enmity as well as of the code of amity.

These were Keith’s last words on the subject. If the grand old man had any noteworthy capacities for self-delusion, they escape the eye. And when he died a few years later, at the age of ninety, with him ended truth’s brief history. His thoughts by then were overwhelmed by the new romanticism (the Blank Slate, ed.) when falsehood came to flower: his sentiments were condemned by that academic monopoly which substituted high-mindedness for the higher learning. And as for almost twenty years no one followed C. R. Carpenter (a primatologist who published some “inconvenient truths” about the behavior of monkeys and apes in the field, anticipating the revelations of Goodall and others, ed.) into the rain forest, so for almost twenty years none has followed Sir Arthur Keith into the jungle of noble intentions.

Beautifully said by the great nemesis of the Blank Slate. Ardrey had much else to say about both Keith and the history of hypotheses about ingroup/outgroup behavior in Chapter 8, “The Amity-Enmity Complex” of his The Territorial Imperative. If you’re looking for source material on the history of the Blank Slate, Ardrey’s four books on human nature wouldn’t be a bad place to start. They’re certainly more accurate than Pinker’s fanciful “history” of the affair. Keith himself was certainly aware of Blank Slate ideologues and their “academic monopoly.” However, he had a naïve faith that, if he only told the truth, he would eventually be vindicated. A hint about the extent to which that faith was realized can be gleaned by perusing the Wiki entry about him, which dismisses him into the realm of unpersons with the usual hackneyed claim of the pathologically pious that he was a “racist,” along with a gleeful notice that he was taken in by the Piltdown skull.

When it comes to the bowdlerization of history, by all means, have a look at the Wiki entry on “Ingroups and outgroups” as well. The most shocking thing about it is the thought that its author might actually believe what he’s written. We learn, for example, that “The terminology was made popular by Henri Tajfel and colleagues during his work in formulating social identity theory.” One wonders whether to laugh or despair on reading such absurdities. The idea that the history of what Ardrey referred to as the “Amity-Enmity Complex” began with some inconsequential “study” done by a Polish psychologist back in 1971 is beyond ludicrous. That’s just one of the reasons why its important to read such important bits of source material as Keith’s book. He actually presents an accurate account of the history of this critical aspect of human behavior. For example,

In brief, I hold that from the very beginning of human evolution the conduct of every local group was regulated by two codes of morality, distinguished by Herbert Spencer as the “code of amity” and the “code of enmity.”

Spencer wrote extensively about the subject in his Principles of Ethics, which appeared in 1892, nearly 80 years before the subject “was made popular” in Tajfel’s “study.” Unfortunately, he also noted the fallacies behind the then fashionable versions of socialism in another of his books, and gave reasons that governments based on them would fail that were amply confirmed by the history of the next hundred years. For that, he was viciously condemned as a “Social Darwinist” by the socialist true believers. The moniker has stuck to this day, in spite of the fact that Spencer was never even a “Darwinist” to begin with. He certainly had his own theories of evolution, but they were much closer to Lamarckism than Darwinism. In any case, Keith continues,

As a result of group consciousness, which serves to bind the members of a community together and to separate the community from all others, “there arises,” to use the words of Professor Sumner, “a differentiation between ourselves – the ‘we’ group or ‘in’ group – and everybody else – the ‘out’ group.”

The passage Keith refers to appeared in Folkways, published by Prof. William Graham Sumner in 1906, also somewhat earlier than the good Prof. Tajfel’s study. Of course, studies by learned professors of psychology are not necessary to document ingroup/outgroup behavior. Just read a little history. Look around you. Can one really understand the furious hatred of Trump by so many highly educated academics and intellectuals absent a grasp of this aspect of human behavior? Are racism, anti-Semitism, religious bigotry, hatred of the “bourgeoisie” or other versions of the “class enemy,” or any of the other myriad versions of outgroup identification that have been documented in our history best understood as the acts of “evil” people, who apparently get up every morning wracking their brains to decide what bad deeds they can do that day, or are they better understood as manifestations of the type of innate behavior described by Prof. Keith? I personally lean towards the latter explanation. Given the incredibly destructive results of this aspect of our behavior, would it not be advisable for our “experts” in evolutionary psychology to devote a bit more attention to it, as opposed to the more abstruse types of sexual behavior by which they now seem to be so fascinated? No doubt it would annoy the hardcore Blank Slaters who still haunt academia, but on the other hand, it might actually be useful.

Sir Arthur had much more to say about the evolution of human nature, including that great tool of historical obfuscation, “group selection.” But that’s a matter best left to another day.
