Living with overconfidence ─ Rather than complete erasure, it is an etiquette of coexistence and monitoring.

We have arrived at the final episode of this series. From Parts 1 to 9, we have traced six layers: the structure of overconfidence, observation, learning, moderation, practice, and self-image. The central proposition of this issue is to reread the declaration I made at the beginning of this series in a new light.Overconfidence cannot be completely eradicated. That is why it is necessary to learn how to live with overconfidence.. Kahneman's warning quoted in Part 1 - ``Learning about overconfidence does little to reduce overconfidence itself'' - was the premise underlying all manners covered in this series. In this article, we will take a final look at that premise and draw out what remains as a long-term practice.Reinhold Niebuhr (1892–1971), the wisdom of "accepting what cannot be changed" contained in the prayers ofErik Erikson (1902–1994)'s theory of adult development,Jon Kabat-Zinn (1944–)'s mindfulness and Buddhist right thought (sati), the rhythm of long-term practice (daily, weekly, monthly, yearly), the etiquette of Sangha (community of practice), and Lao Tzu's ``The Good and the Young Water'' -- the etiquette for continuing to live with overconfidence, as the culmination of this series.

01Consequence of this series: overconfidence never goes away

At the beginning of Part 1, we quoted Kahneman's warning. "Among human judgment biases, no one is more persistent, more difficult to correct, or more serious in its consequences than overconfidence. Even if you learn about overconfidence, overconfidence itself will hardly decrease.The nine chapters in this series -- Structural Theory, How to Read Signs, Defense Mechanisms, Attribution Bias, Observation, Learning Theory, Moderation, Practical Techniques, and Self-Image Theory -- are all premised on this warning.

Let me clarify once again the outcome of this series.The task of reducing overconfidence is not a task of elimination, but a task of coexistence and monitoring.. There is a limit to the amount of overconfidence that each technique can improve, including the calibration training, Pre-mortem, and Reference Class Forecasting that we covered in Part 8. The same applies to etiquette at the self-image level (Part 9). Even if you make all these habits, overconfidence itself will not go away. What remains isNotice faster, respond more calmly, and fix faster. It's ability.

"The difference between a mature judge and an immature judge is not whether they have overconfidence or not, but how quickly they notice overconfidence. Both fall into overconfidence. The difference is that immature ones continue to act without realizing it, while mature ones notice, stop, and make corrections. The speed of awareness makes the difference in the quality of judgment." - Purpose from George Vaillant's The Wisdom of the Ego (1993)

The structure of this episode is as follows. The first half (sections 2 to 6) traces the theoretical foundations of long-term coexistence, and the second half (sections 7 to 10) provides practical manners and concludes the series. The most in this series quiet Frame it as an episode with character.

02All 10 maps ─ Structure of three chapters

As the final part, we will take a look at the overall structure of this series. The 10th edition has been divided into three chapters. Here we will summarize the achievements of each chapter and the overall conclusion of this issue.

The three chapters are not independent, but layered. Without an understanding of the "why" in the first part, the manner of the "awareness" in the second part becomes technocratic. Without the second part, ``Awareness'', the third part, ``Living with it'', will remain as an idea. And without the "living with it" readiness of Part 3, the work of Parts 1 and 2 will burn out under the strain of corrective overconfidence. three chapters at the same time Growing up is the whole idea of etiquette proposed in this series.

03Niebuhr's Prayer - Accept what cannot be changed

The American theologian was the person who most succinctly put into words the proposition that overconfidence cannot be completely eradicated. Reinhold Niebuhr is. He wrote this prayer around 1934, which later became one of the most widely known prayers of the 20th century through Alcoholics Anonymous (AA).Serenity Prayer is.

“God, grant me the serenity to accept the things I cannot change, the courage to change the things I can, and the wisdom to know the difference.” -- Reinhold Niebuhr, The Serenity Prayer (c. 1934)

Although written in a religious context, this prayer of Niebuhr is universal in content. Three elements that directly reach the theme of this series ── accept、change、distinguish ── Contains.

Niebuhr's prayer integrates the specific techniques covered in Part 8 of this series and the attitude of "living with it" in this part in a single composition.Intervene with courage where things can be changed, remain calm where things cannot be changed, and continue to distinguish between the two each time. ──This is the core of the etiquette for long-term coexistence with overconfidence that this series depicts.

04Erikson のジェネラティビティ ── 成熟した成人の発達課題

How should we position long-term coexistence with overconfidence in the developmental stages of life? The person who most systematically answered this question was an American developmental psychologist. Erik Erikson It was. His life cycle theory, presented in 1950's Childhood and Society, forms the basis of modern developmental psychology.

In Erikson's argument, what is important in the context of this article is the developmental tasks that he established in adulthood (approximately 40 to 65 years of age). generativity vs stagnation This is a pair of Generativity is the ability to nurture the next generation, contribute to society, and invest in something bigger than yourself. Stagnation is a state of being confined to oneself and remaining in one's own self-centered concerns.

"A central developmental task in adulthood is to extend our concerns beyond ourselves to what we will leave behind for the next generation. Generativity is not simply about producing offspring or making achievements. It is the ability to reposition one's wisdom and experience within the broader human context." - Erik Erikson, Childhood and Society (1950), Chapter 7 Purpose

Rereading Erikson's generativity in the context of this series reveals the long-term purpose of living with overconfidence.The task of reducing overconfidence is not only about improving the quality of one's own judgment, but also about what we leave behind for the next generation of judgers -- juniors, young people, and future experts.. In the context of a materials auditor, can you leave behind a culture that makes you aware of overconfidence in the industry, organization, and team after you retire? This is a question of generational responsibility that goes beyond individual work.

Another concept of Erikson's later years waswisdom ── As a developmental issue in the final stage of life (after approximately age 65). Wisdom, as he described it, is not about arriving at certainty.The ability to still live despite uncertainty and limitations is. This resonates deeply with the etiquette of "living with overconfidence" that this series has presented.

05Mindfulness: simultaneous monitoring and acceptance

One of the most practical techniques for living with overconfidence is based on modern psychology. Mindfulness ancient Buddhism rediscovered as 正念 (sati) This is the etiquette. American molecular biologist and meditation instructor Jon Kabat-Zinn was started at the University of Massachusetts Medical Center in 1979. MBSR (Mindfulness-Based Stress Reduction) The program translates Buddhist meditation traditions into modern medical and psychotherapeutic treatments and has been the subject of extensive empirical research over the past 40 years.

Kabat-Zinn himself provides the core definition of mindfulness:

"Mindfulness is the practice of paying attention to the present moment intentionally, without judgment. It refers to a state of being aware of what is happening, but not being reactively involved in it. It is a special quality of consciousness in which awareness and acceptance are simultaneously present." - Jon Kabat-Zinn, ``Full Catastrophe Living'' (1990) Purpose

In the context of the final episode of this series, what does mindfulness offer? Simultaneous monitoring and acceptance is. Being aware of overconfidence (monitoring) must be accompanied by not blaming yourself for having overconfidence (acceptance). Monitoring alone creates tension and is not sustainable as a long-term practice. Acceptance alone leaves overconfidence alone. The simultaneous establishment of both is the core of long-term coexistence with overconfidence.

Kabat-Zinn's MBSR is organized as a structured eight-week program. Not all readers of this series need to take MBSR, but its core tenets - non-judgmental, intentional, present attention - can be incorporated into everyday decision-making situations. We will discuss this more specifically in the next section, the rhythm of long-term practice.

06Rhythm of long-term practice: daily, weekly, monthly, yearly

Rhythm is necessary to sustain the manners presented in this series over the long term. As part of our practice, we will propose a rhythm of practice on four time scales. This is not a checklist to get everything done perfectly. This is a rhythmic proposal that you can choose from at your own pace.

The common principle of the four rhythms isCoexistence with overconfidence is not a matter of instantaneous determination, but is nurtured within structured time. That's what it means. Small daily reviews support weekly pre-mortems, enable monthly calibration checks, and make annual comprehensive rereads meaningful.The long-term accumulation of small practices is the essence of etiquette for living with overconfidence.。

07With friends ── Sangha etiquette

It is difficult to continue work alone that involves overconfidence. This is a point that this series has repeatedly emphasized. The 6th M&M conference, the 7th Bohm Dialogue, the 9th Trustworthy Interlocutor—all demonstrate the importance of coexisting with overconfidence. in a relationship I have been referring to it as something that grows. The Buddhist tradition has the concept that most clearly articulates this. Sangha, that is, a community of practice.

In Buddhism, as the Three Treasures 仏 (Buddha)・法 (Dharma)・僧 (Sangha) が並べられます。Sangha は、悟りを求めて共に歩む仲間の共同体です。釈尊は晩年、弟子の ananda When asked, ``Is having good friends half the path to holiness?'', he reportedly answered as follows.

"No, Ananda, do not say so. Having good friends is not half of the holy path; it is the whole of the holy path (Mā hevaṃ, Ānanda, mā hevaṃ. Sakalam evidaṃ, Ānanda, brahmacariyaṃ, yad idaṃ kalyāṇamittatā)." From “Seibu” 45.2 “Half Sutta (Upaḍḍha Sutta)”

This answer of the Buddha resonates deeply in the context of the final episode of this series.The task of living with overconfidence cannot be completed alone. It becomes sustainable only in the presence of good companions as "all of the sacred path". In the context of materials reviewers, a team that shares a culture of being aware of overconfidence, colleagues with whom you can openly discuss your judgmental habits, and a mentor who can maintain your trust over the long term - these are not luxuries, but are essential to coexisting with overconfidence. Requirements is.

The concept that modern organizational psychology has rediscovered as “psychological safety” (Amy Edmondson 2018) also has a direct connection to Sangha etiquette. Uncertainty in judgment, one's own habits, past failures -- whether or not there is a place in the organization where these can be shared will determine the organization's overall ability to resist overconfidence. The sixth edition, Just Culture, can also be understood as a form of contemporary institutionalization of the Sangha.

08Lao Tzu's ``The Good, the Young Water'' -- the last words of this series

At the end of this series, we return once again to the Eastern classics.Lao Tzu の『道徳経』第八章には、次の有名な一句があります。

"Higher goodness is the youth of water. Water is good and benefits all things and does not fight, but deals with the evils of all people. Therefore, it serves the path.

Lao Tzu shows us that the best way to be is something like water The proposition is that. Water benefits all things and does not compete with anything. He voluntarily enters the low places that everyone avoids. That's why, Lao Tzu says, it's close to the dao.

本シリーズの最終回として、老子のこの言葉が指す場所を、もう一度本回の主題に重ねます。The etiquette of living with overconfidence is as soft as water.. Rather than having a fixed self-image (Part 9), we should have the flexibility to change our form depending on the situation. It's not about asserting certainties, it's about the humility of putting yourself in a lower place when needed. The plasticity of not being afraid to make corrections and changing the flow in response to new information. These are the quietest expressions of all the manners we have covered in this series.

"Place yourself in a place where everyone is wrong" - Place yourself in a place that everyone would like to avoid. Rereading this in the context of this article, admitting that you are overconfident, making public your judgmental habits, and acting with uncertainty -- these are places that many experts want to avoid. However, Lao Tzu pointed out 2,500 years ago that putting yourself in that place is the closest path to becoming a true judge. All the consequences of this series converge here.

09In the pharmaceutical field ─ 4 situations of long-term practice

Let's bring abstract theory back to the field. In the career of a materials examiner, we will identify four situations in which long-term coexistence with overconfidence is tested. These are not specific judgment situations, but rather challenges that recur throughout your career.

The structure common to the four scenes isCoexisting with overconfidence is not something that is perfected at a specific time, but continues to take different forms at each stage of your career. That's what it means. The manners presented in this series are useful at any stage, but their meaning changes depending on the stage. This is the significance of continuing to carry this series as a long-term practice.

10Final Etiquette ─ 5 Obi

At the end of this series, we will organize the manners that cover all 10 lessons into five belts. These are not independent techniques, but interwoven structures of lifelong practice.

The five belts need to be cultivated together, not independently. People who are only aware become nervous. People who are strong only in acceptance do not create change. People who are strong only in correction become isolated. People who are only strong in relationships forget about internal work. People who are only strong in their generational belt will put off their own work.Growing all five belts at the same time is the whole picture of etiquette for living with overconfidence.。

Overconfidence cannot be completely eradicated. That is why it is necessary to learn how to live with overconfidence - I returned to the proposition I made at the beginning of this series once again in the final episode. Niebuhr's Prayer, Erikson's Generativity, Kabat-Zinn's Mindfulness, the Rhythm of Long-Term Practice, Sangha's Etiquette, and Lao Tzu's "Greater Good and Young Water" - six traditions bring together the entire outcome of this series in one composition.

In the first part of this series, we wrote: "After honing your confidence in the previous series, you need training to recognize overconfidence.".In the final episode, I will add another proposition.As you continue to practice noticing overconfidence, your true self-confidence will deepen.. The two are not in conflict. The previous series, ``How to Gain Confidence,'' all 10 episodes, and this series, ``Recognizing Your Overconfidence,'' all 10 episodes, serve as companion etiquette that should be cultivated throughout your life.

As I finish this series, I will leave you with the quietest words at the end.To live with overconfidence is to live with imperfection. This is not a defeat, but a sign of maturity. Free yourself from the strain of trying to be a perfect judge, and continue to judge, act, and relate despite your imperfections. This is how Jung, Rogers, Winnicott, Maslow, Erikson, Kabat-Zinn, and Lao Tzu and Buddha all referred to the same place with different words. Herein lies the final meaning of this series for materials auditors.

I would like to express my deepest gratitude to all the readers who have continued reading this series thus far. From now on, it's time for long-term practice. Daily small reviews, weekly pre-mortems, monthly calibration checks, and annual rereading of the book series -- may these continue to quietly support you throughout your life as a judge.
