AN ARGUMENT FOR THE FLEXIBILITY AND MODIFIABILITY OF HUMAN BEHAVIOR
Author (and biological anthropologist) Melvin Konner wrote in the preface to this 1982 book, “We need theories that are incisive and illuminating, enabling us to grasp the solution at once; they must transcend the complexities, paring away all that is irrelevant, leaving the elegant, decisive beauty of a Euclidean proof… I offer no such theories. It is my belief that the failure of behavioral science up to the present day results, precisely, from the pursuit of them… A good textbook of human behavioral biology… will not look like Euclid’s geometry… but more like a textbook of physiology or geology, each solution grounded in a separate body of facts and approached with a quiverful of different theories, with all the solutions connected in a great complex web. The pages that follow form a sort of game plan for such a text.” (Pg. xv)
He states in the first chapter, “It seems t me, too, that we must return to nature, and for human beings this means in some sense a return to the human condition as it was lived when people were evolving. I do not see any much better proposal for discovering how to modulate the social chaos now swirling constantly about this helpless planet.” (Pg. 10)
He asks, “How can these dramatic findings of structural change in response to experience be reconciled with the weight of evidence in favor of circuit-building in the absence of stimulation of even function?... we have ample evidence that stimulation can play a major role in some aspects of embryonic brain growth, and that, conversely, some major events of postnatal brain development can proceed very nicely without the sorts of specific experience that might be expected to be relevant.” (Pg. 80)
He notes the “sloppiness of what has often passed for respectable research in this field. IN the twin studies on which so much of recent theory is based, the statistical procedures of inference have usually been simply inappropriate to the task, and given the relatively small numbers of twin pairs, findings could easily have arisen by chance. Also, it may turn out that genetically identical twins are more similar than nonidentical twins because parents treat them more similarly… Moreover, some famous studies of identical twins reared apart did not insure against separate but highly similar rearing, and in some cases ‘separated’ twins went to the same school and were in frequent contact.” (Pg. 95)
He points out of the “Ape language” experiments involving a chimpanzee named Nim Chimpsky: “while Nim’s mean utterance progressed to a point at which it was greater than one sign, it didn’t grow beyond that. At age three and a half, when a human child … would be racing toward sentences, Nim was still hovering between one- and two-word phrases, where he had been for two years. Nim never produced utterances longer than two words that could be said unequivocally to be grammatically rule-bound. His percentage of imitations of trainer utterances remained high when it should have bene declining. He rarely expanded on his caretakers’ utterances, something human children do frequently, and he never learned turn-taking---necessary for true conversation.” (Pg. 168)
He states, “What seems certain to me… is that no cultural training, however designed, can eliminate the basic core of capability of violence that is part of the makeup of human beings. The continued pretense by some social scientists and philosophers that human beings are basically peaceable has so far evidently prevented little of human violence… Perhaps we could let it go for a while and see if the other assumption gives us a better understanding; if it does, it will give us a better chance at control.” (Pg. 207)
He explains, “If I did not believe in change, I would not write books… This book… is not one-sided. I believe it is impossible to read even a single chapter without coming away with a strong sense of the flexibility and modifiability of human behavior.” (Pg. 382)
He summarizes, “Human beings are irrevocably, biologically endowed with strong inclinations to feel and act in a manner that their own good judgment tells them to reprehend---that is, if they are in the least capable of sympathy with the suffering of other human creatures, or if they have any sense of joy and order and beauty---all these evolved for other purposes than to save the human species from a protracted, dissolute destruction. Yet there they are. Can we not turn them now to this latter purpose?” (Pg. 427)
This book will be of keen interest to those studying biological influences on human behavior.
