“The fool’s heart is on the tip of their tongue; the wise’s tongue is in the extreme bastion of their chest.”
M. Fethullah Gülen [1]

Throughout human history, numerous writers, philosophers, scientists, and religious scholars across different eras, geographies, and cultures have arrived at a common point about interpreting society and people. This finding—long known as the “audacity of ignorance”—has only recently been addressed scientifically.

Two American social psychology professors, David Alan Dunning and Justin Kruger, conducted social experiments to scientifically prove Charles Darwin’s theory “Ignorance augments one’s self-confidence more than true knowledge.” In Dunning and Kruger’s experiments, participants were given four tests in the areas of humor, grammar, and logic. They were then asked to evaluate their own performance and estimate how many questions they would have answered correctly. The results revealed that participants who performed poorly on the tests rated their own performance above average. The researchers called this the “double burden” of unskilled people and stated that it was due to the individual’s lack of ability to evaluate their own knowledge and experience. According to them, the main problem was that they were “unskilled and did not know they lacked proficiency” [2].

Dunning and Kruger formulated their results as follows:

1. Incompetent people always overestimate their own abilities.
2. They do not realize the extent of their own inadequacies.
3. Because of their ignorance, they do not feel the need to improve their knowledge and skills.
4. They consistently underestimate the superior qualities of others.

The study also found that the best performers were the humblest who underestimated their knowledge and abilities [3].

The Dunning-Kruger Effect is two-sided: Unqualified people exaggerate their own knowledge and abilities; and on the flipside, people who are truly experts in their field tend to behave humble and downplay their experience and abilities [4].

Since experiments in the positive sciences have measurable parameters, their results are more reliable; human psychology is much harder to study, as the number of variables affecting the outcome is exceptionally high. Therefore, research in this field must be more extensive and eliminate the parameters that affect the outcome by deploying objective criteria.

In a study on the Dunning-Kruger effect in Southern Illinois University aviation students, students were tested on both grammar and piloting knowledge. The results of the study supported the DK effect and revealed that students with low scores overestimated their abilities, while students with high scores underestimated their abilities [5].

In a 2018 study examining the development of overconfidence in new hires, it was observed that the self-confidence of people who exhibited a humble attitude at their hire was far ahead of their performance with little experience. As they continued to gain experience, their self-confidence first fell and then surged again in proportion to their performance [6].

In 2021, another study attempted to prove the existence of the Dunning-Kruger effect using electroencephalography (EEG), which records the electrical signals in the brain. Participants in the bottom quartile overestimated their percentile and participants in the top quartile underestimated their actual scores. In the experiment, where the reaction times of individuals at these two levels were also measured, it was found that those in the lower quartile reacted faster, while those in the upper quartile reacted slower. It was also observed that dissimilar mental processes occurred in the brains of these two groups during the evaluation [7].

In another recent study, the existence of the DK effect was tested under the conditions of the COVID-19 pandemic. The study surveyed 2,487 participants, asking them about their level of education, sources of information, and COVID-19. Finally, the participants were asked how many questions they could have answered correctly. Poor performers’ self-estimates were disproportionate to their actual level of knowledge and much higher than the overall average. They were also found to have lower levels of education than other participants and to prefer social media and mass media as sources of information [8].

If the person under the Dunning-Kruger Effect realizes their ignorance and gains knowledge and experience, they can overcome the negative effects of the phenomenon. There are four main periods of self-confidence in this process:

Mount Stupid: This is when the Dunning-Kruger effect is at its peak, when people are pretentious in their own knowledge on a subject about which they have meager information.

Valley of Despair: This is the stage when one faces the inadequacy of one’s existing knowledge. When one realizes how little they actually know, their self-confidence sinks. The sentiment, “I know everything,” is replaced by, “There is much more than I know.”

Slope of Enlightenment: The person who has fallen to the lowest point of despair pushes themselves to increase their level of knowledge and skill and makes progress. From the Valley of Despair, they gradually climb towards the Slope of Enlightenment. This is the stage where real learning begins.

Plateau of Sustainability: This period does not imply that the person has mastered all knowledge. The person can now clearly draw the boundaries of their level of knowledge on a certain subject. They can clearly identify what they do not know, and make an effort to do so. Self-confidence rises again, but the tendency to be modest may also increase [9].

Conclusion

This phenomenon, which has always been controversial, continues to tempt both supporters and opponents with new research. As of today, the Dunning-Kruger Effect is not recognized in the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5). It is still recognized as a psychological phenomenon rather than a pathological condition. However, it is sad that the phenomenon described is visibly common in society. When we think about it, it is not hard to find people under the influence of the DK effect in business, education, politics, sports, and arts. Especially during the COVID-19 pandemic, we sadly witnessed those with little knowledge on the subject make statements on social media and mass media and pass laid-back judgments in contrast to the experts.

In an interview, Dr. Dunning said, “The key mistake people make about the Dunning-Kruger Effect is about who falls victim to it. The effect is not really about others; it is about us. The lesson to be drawn is how humble and cautious we should always be about ourselves.” The Dunning-Kruger effect affects not only ignorant or unskilled people. It impacts us all about the things we are yet to learn [10].

From a different perspective, “ignorance” has always been a major human weakness traditional scholars have addressed throughout history. Fethullah Gülen explains that there are three degrees of ignorance. “Simple ignorance” is when a person does not know; “double ignorance” is when they do not know that they do not know; and “triple ignorance” is when they think they know, although they don’t. In relation to this Gülen said, “The Arabic word muq’aab means “three-dimensional” and ignorance at this level is almost impossible to eradicate. It leads people to diverse delusions; sometimes into tyrants, sometimes into the likes of Yazid ibn Muawiya or Hajjaj ibn Yusuf, and sometimes into a Führer, down every path except the straight one” [11].

Bediuzzaman Said Nursi also draws attention to the connection between knowledge and humility: “In society as a whole, everyone has a window, known as rank, through which to see and be seen. If the window is higher than a person’s stature, he will grow taller through arrogance, but if it is lower, he will bow down out of modesty to see and be seen at that level. The measure of greatness in man is smallness, that is, modesty. The scale of smallness is bigness; that is, arrogance” [12].

Answer: Self-confidence, or self-esteem, is usually defined as a person’s believing and trusting in himself, relying on his personal abilities and opportunities, living in peace with his own person and environment, and being content with himself in general. Even though it has a positive aspect in terms of urging us to look at life positively, this term is an expression of a notion whose underlying meaning and connotations do not comply with universal humane values. The term “self confidence” expresses a perspective which originates from an egotistic worldview.

Naturally, a person’s character needs to be revealed in order to be able to improve his or her talents and capabilities. However, while seeking their development we should not flatter individuals excessively and throw them into whirlpools of egotism. We should not make a person become a know-it-all and act insolently; we should not let issues rely on a single individual’s restricted personal capabilities, limited power, and feeble will.

First of all, it is inevitable for a person who approaches every issue with respect to his or her personal talents, power, and capacity and keeps saying “I” to become totally egocentric; it is inevitable for them to grow more and more arrogant by feeding their ego with every achievement and everything they do. On the other hand, it is also obvious that a self-centered person who has too much trust in himself will become completely desperate at the slightest slip or fall; he will not find anything to hold on to and will not be able to rise again.

People have the sense of and need for confidence engrained in their nature. However, a person who does not know whom he should trust and who cannot correctly identify the true source of reliance will finally turn into a complete egotist and he or she will ascribe every matter to himself or herself. Such a person will even nurture some perspectives leading to unbelief; she or he will go too far and-God forbid-say, “I have created…”, or “such and such has created….” In time, these people will become narcissists, self-admirers who are fond of themselves, their behavior, their manners, and their appearance. They will be ready to reject and criticize any thought, measure, and solutions other than their own.

In this respect, a principle of “fulfilling what befalls on the free will and then relying on God” should replace the notion of self-confidence in the eyes of a true believer of God. Humans are blessed with the “free will,” which is a very special gift. We are responsible for using all the senses and feelings granted by God Almighty as capital, but expect the result and reward from Him again. Likewise, the feeling of confidence is always ascribed to God in the Qur’an and the practical example of the Prophet, since God Almighty is the one who creates everything and who directs every affair. If we use the potentials placed in our nature as seeds and then put them to practice as an intention and wish to be realized, God Almighty grants us the power and possibility to accomplish that act. Regarding it as mental power, as directing one’s own thoughts and actions with that power, or as God’s direct favor on the human free will within the sphere of causes, no matter how we define fulfilling what befalls the free will, when we wish to do something and incline towards it, the Creator of the Universe renders it possible for us to realize that intended act. Therefore, we should always put our faith in God and rely on His execution. Accordingly, true believers firstly have faith in God in every matter and make use of the abilities He has bestowed on them. In addition, they ascribe achievements not to themselves but to Divine Providence. They know that all of these come from God and they have complete faith that future achievements also lie in the power of God. Such people, while fully acknowledging their impotence and weakness, are very powerful at the same time, for they are well aware of the true source of power. Such people are very rich, since they are conscious that they are fed from the treasures of Divine Mercy. They become heroes of the fact that “belief is both light and power. Those who attain true belief can challenge the universe.” (Nursi, Twenty-Third Word). Therefore, they have the courage to defy worlds. The fortress they take refuge in and the sword they make use of is the truth, “There is no power except with God.”

Yes, true believers make use of the free will granted by God in the best way possible. On the other hand, they pray as “O God, please do not leave me with my carnal self even for a span as short as the blink of an eye,” putting their trust not in their own selves, but in God Almighty. They take their carnal self and carnal desires as their archenemy and take only God as their best supporter, sole friend, and helper. In the face of every event, they croon, God is sufficient for us; how excellent a Guardian He is! (Qur’an, 3:173), and they voice the truth, O Our Lord! It is in You that We have put our trust, and it is to You that we turn in utmost sincerity and devotion, and to You is the homecoming (Qur’an, 60:4). They always keep loyal to the divine decrees:

“And put your trust in God. God suffices as One on Whom to rely (and to Whom to refer all affairs).” (Qur’an, 33:3)

“God is sufficient for me; there is no deity but He. In Him have I put my trust, and He is the Lord of the Supreme Throne (as the absolute Ruler and Sustainer of the universe and all creation, Who maintains and protects it).” (Qur’an, 9:129)

Nevertheless, nowadays saying “I” in everything one does and overflowing with arrogant considerations is more common than ever. Egotism is so widespread today that most people use even what has been granted by Divine Providence in the name of their arrogance and use it as elements to feed their ego. For example, most of those who put emphasis on self-confidence contract the plague of vanity in time; they are seized by a feeling of superiority and catch the egotist disease of talking about themselves at every opportunity. Therefore, the term “self-confidence” or “self-esteem” is impossible to reconcile with the perspective of a believer in the true sense of the word. It is a very unnatural term from the standpoint of faith, for it misguides minds and hearts like other spurious expressions do. With an understanding based on the essential values of belief, we all need to pray, “Hold me, O God. Hold me, please. I cannot do without you!”
