Introduction
The Cambridge Online Dictionary defines several types of denial, including denial of truth, denial or refusal of a service (or a person), denial as ‘failure to admit responsibility, knowledge or status/condition’ (such as climate change denial) and finally psychological denial.
Medical denial is often closely related to psychological denial, and covers an entire gamut of conditions including willingly ignoring unpleasant or unavoidable facts about serious illnesses and mental states or other stressors in one’s personal life. Both (medical and psychological) are so-called ‘defense’ mechanisms.
These final two types (psychological denial, and failure or inability to acknowledge) may be the wellspring and source of all other types, and therefore the focus of this brief essay.
The several types of denial (as defined above) are usually (and eventually) merely damaging to individuals on a personal scale. However, another type of denial, which can be called historical or societal denial, can have much wider ranging effect across societies, nations, and the lesson of history itself.
Perhaps one of the best (if most controversial) examples of this type of denial is Holocaust denial’. Whether one thinks the Holocaust happened or not, failure to learn from (or at least acknowledge the possibility of) these types of events leads to history constantly repeating itself in nations all over the world, including Africa, Bosnia and Armenia. These devastating events are the prime result of a nationwide or societal need for denial, perhaps more damaging to the body politic than the body itself.
The Psychology of Denial
Most of the least desirable elements of human psychology do not bear well under close examination, if only because of the difficulty of confronting that part of ourselves which we would rather not look at too closely.This state of mind is called denial.
Such behavior is responsible for enacting, and then concealing some of the most reprehensible crimes of human history. Such indiscretions, usually perpetrated on a large scale, are most commonly called ‘crimes against humanity’, possibly the highest (and lowest) types of crimes that human beings can commit against one another.
One of the starkest of these negative elements, the psychology (and act) of denial, can start in childhood (as habitual lying) and can sometimes grow as the indiscretions (and the child) grows. Denial at this age is typically used to cover up complicity in any number of childhood misbehaviors or perceived failings, to avoid punishment, or hide instances of recurring abuse for fear of reprisal from a predatory parent or other adult.
Between adolescence and adulthood, some children and young adults learn that denial (of their growing list of negative personality traits and actions) is an easier (short-term) solution to their problems than confronting them head on.
This form of lying and prevarication is an early defense system based on denial (of truth), which, if left unchecked, can sometimes grow into even worse behavior in adulthood, since it offers a seemingly easy solution to unpleasant realities. By extension, a culture of such behavior on a national scale can result in an idiosyncratic nationwide belief system based on half-truths and falsehoods. Such a state will become a system in which the complex shortcomings of that society can only be addressed by blaming them on (imagined) outside influences, such as political or cultural adversaries, or, more often than not, minority groups, indigenous or otherwise.
This behavior is a failing of the entire human race, not limited to one ethnic group or people.
From its childhood, beginning to quite possibly the highest practice of denial, (that of genocide and holocaust denial, and even climate change denial) the psychology and reasoning are the same. Arrogance is certainly a factor, and it is usually accompanied by a profession (usually false or perceived) of ignorance, fear of (international) retribution and swift justice, including (economic) sanctions and even ostracism.
When large groups of people or nations exercise denial on a massive scale, other elements of psychology come into play, including but not limited to a proclaimed ignorance of the (well-established) facts, or the inability to comprehend or even fathom or accept the (horrific) details, once they become known.
Therefore, nationalistic and governmental denial is a slightly different, even more peculiar type of feigned ignorance, a form of national/political self-delusion that masquerades as a shared idealism intensely stubborn at its core, and is a misuse of group and/or national power, made even more so if the ‘deniers’ find themselves outnumbered by those of opposing beliefs.
Yet it goes back to the same core psychology that children use when they decide to lie about their indiscretions instead of being taught how to own up to and correct them, if such behavior is allowed to go unchecked. To the blindness created by the mindset of denial, a dead bird is not much different from an exterminated people.
Conclusion
Denial (and its close cousins altruism, and self-sacrifice) most likely arose as evolutionary survival behaviors of proto human primates, which were then passed down to their present descendants by the simple process of being inherited from earlier forbears whom survived long enough (and often enough) to have their traits bequeathed to Homo sapiens.
(The ability to ignore danger to self in order to rush to the aid or service of another is, of course, a form of denial, albeit one of the highest caliber. It is a brief denial of the possibility of danger to self. One could assume, quite logically, that our altruistic ancestors probably survived more often than the self-sacrificing ones because they were able to pass on these tendencies, if self-sacrifice often resulted in the loss of life of those noble individuals.)
As an evolutionary behavior, the question must be asked if there any examples of this type of behavior in so-called lower species? Animal mothers often ignore or effectively deny the existence of considerable danger to themselves in defense their young. Could this behavior be called (denial of danger to self), altruism, or self-sacrifice? The question then becomes, ‘is this trait strictly limited to human beings and human societies, and if it is not (limited to us), then what lessons may we learn from those other life forms, if any?’
The idea of whether other types of animal life-forms (such as other primates) can experience denial or any of the other types of ‘higher’ mental/emotional aberrations (or even illnesses linked to higher intelligence) is one still contentiously debated. Our closest cousins the higher primates certainly display many of our mental and emotional states, and their societies suffer as much as ours do from their apparent inability (or, for our part, unwillingness) to learn the lessons of (our) history, or simply ignore those lessons by denying their historical antecedents.
Denial is a two-edged sword, having evolved, on the one hand, as an altruistic trait that helped ensure the survival of the group, and on the other hand detrimentally, as a way of evading or ignoring harsh truths about ourselves, our societies, and now, even our world. Those aspects (of denial) may have saved us just as surely as the other aspects could eventually end us.
