Psychological safety is just one of many tools.
Read the original article (in Japanese):
Introduction | Psychological Safety Depends on How It Is Used
“Young employees’ opinions are not heard.”
“If you make a mistake, you are harshly blamed.”
“That’s why people quit.”
In recent years, psychological safety has increasingly been used to frame discussions about these workplace issues.
Certainly, the concept itself is important. An organization where people cannot speak up, hide mistakes, or suppress doubts cannot be considered healthy. In that sense, the argument that psychological safety is necessary is correct.
However, the real problem lies in how the concept is used.
In discussions like those in the original article, the argument often shifts toward the idea that managers and senior staff should adapt to each individual employee and communicate in ways that never cause discomfort. But if that approach becomes a fundamental principle of management, another problem emerges.
Management itself becomes unsustainable.
Organizations bring together people with different personalities, values, and perspectives. It is impossible to perfectly adapt to everyone. If managers are expected to create a “personally tailored environment” for each employee, organizations fall into the trap of individual optimization, managers become exhausted, and common rules begin to dissolve.
So what should we aim for?
The answer is not to treat psychological safety as absolute.
What matters is how it is used under the larger goal of organizational and business growth.
In this article, psychological safety will be reconsidered not as kindness or indulgence, but as a tool for building a growing organization.
Chapter 1 | Misunderstanding Psychological Safety
First, we must clarify one thing.
Psychological safety does not mean never being criticized.
When the term spreads without context, it is often interpreted as “never rejecting ideas,” “never hurting feelings,” or “never correcting mistakes.” But that interpretation misses the point.
Harvard professor Amy C. Edmondson, who proposed the concept, defines psychological safety as a state in which people can express opinions, raise questions, or report mistakes without fear of negative consequences.
In practice, this means:
-
You can voice opinions without punishment
-
You can raise doubts without being excluded
-
You can report mistakes without personal attacks
In other words, there is a certain level of tolerance for speaking up and acknowledging mistakes.
However, that tolerance is not unlimited.
Psychological safety does not mean that any opinion is valid or that any failure must be accepted unconditionally. Its meaning exists within the larger objective of organizational and business growth.
If even proposals that have already been tested and proven ineffective must be respected simply because they are “opinions,” learning disappears and confusion replaces progress.
What truly matters is enabling rational experimentation.
Psychological safety is therefore not an unlimited immunity zone, but a space for dialogue that allows organizations to learn and move forward.
Chapter 2 | The Primary Objective Is Organizational and Business Growth
What is the primary objective of a company?
The answer is simple: organizational and business growth.
Employee development, listening to younger employees, and promoting psychological safety are all important.
But they are means, not ends.
This order must not be reversed.
Consider the importance of professional “forms” or standard practices.
Organizations that neglect fundamentals lose consistency, weaken training systems, and suffer declines in quality. Every field—sales, service, planning, manufacturing—has established practices that must first be learned.
Yet treating those practices as absolute is equally wrong.
They are safety frameworks created through experience, not excuses for intellectual stagnation. Statements like “work for ten years before speaking” or “young employees should stay silent” represent stagnation, not respect for tradition.
The same applies to evaluating ideas.
Judging ideas based on age or seniority is not proper management.
The real question should always be:
Does this contribute to organizational and business growth?
If a younger employee presents an idea that advances the organization, it deserves consideration. If a senior employee clings to outdated thinking, it should be reconsidered.
Employee development and psychological safety must therefore always be understood in relation to organizational growth.
Of course, this does not mean companies can treat employees poorly. Such behavior leads to resignations and reputational damage, ultimately harming growth itself.
Chapter 3 | Human Progress Has Always Come Through Experimentation
Human society itself has expanded through experimentation.
Pufferfish contains deadly poison. Konjac root is inedible without processing. Many mushrooms are dangerous. Yet humanity did not avoid them entirely. People experimented, observed, processed, and eventually established safe methods.
In other words:
Experiment → Verification → Learning → Formation of standards
This process expanded human life.
Importantly, standards did not exist from the beginning.
They emerged from repeated experimentation.
Standards define “what is safe,” but progress requires occasionally pushing beyond them. Innovation, technology, and business growth all depend on that process.
Psychological safety enables this in modern organizations.
In workplaces where mistakes are never tolerated and new ideas are discouraged, no one will experiment. Questions disappear. Dissent disappears.
Risk may temporarily decline, but nothing new is created.
Psychological safety is therefore not about kindness.
It is a condition for progress.
Chapter 4 | Personal Fit Is Not the Essence of Organizational Management
Another important point is that psychological safety must not be mistaken for excessive individual accommodation.
If an organization must constantly adjust to every individual’s sensitivities, that often means the employee is not truly a fit for the organization.
Naturally, harassment and abusive behavior are unacceptable. But excessive managerial caution is also unhealthy.
The burden ultimately falls on managers.
-
Tailoring language for each individual
-
Providing personalized emotional support
-
Adjusting feedback for every sensitivity
If these expectations become limitless, management collapses. Managers themselves are part of the organization; if they fail, the organization weakens.
Continuing clearly dysfunctional relationships benefits no one.
Organizations should not prioritize maintaining headcount at all costs.
Sometimes decoupling—separating incompatible relationships—is necessary.
Employee departures are not always failures; they can represent healthy renewal.
Chapter 5 | Organizations Should Be Designed Around the Greatest Common Denominator
There is no permanent organization.
Organizations constantly experience entry and exit.
People join, people leave, markets change, and businesses evolve. Organizations are inherently fluid.
Therefore, the goal should not be the perfect environment for everyone.
Instead, it should be the greatest common denominator of a healthy environment.
A certain level of psychological safety, growth potential, and adaptability.
Rather than optimizing for a single individual, organizations should create a shared foundation that allows many people to function effectively.
This approach is the opposite of personal optimization.
The goal is not perfection, but optimization.
Without that realism, organizations cannot endure.
Paradoxically, designing around the greatest common denominator maximizes total engagement across employees.
Chapter 6 | Why Japan’s National Soccer Team Is Considered Strong
This concept can also be seen in sports.
Japan’s national soccer team does not necessarily possess the world’s greatest individual players like Messi or Mbappé.
Yet in recent years Japan has consistently been regarded as a strong national team.
The reason lies in greatest-common-denominator organizational management.
Tactical discipline, role clarity, teamwork, and coordinated play create a strong organizational foundation. That stability produces consistent results.
Moreover, when exceptional individual talent appears, a strong organizational structure can amplify that talent.
The same applies to business.
Companies should not depend solely on a few exceptional individuals.
They should build organizations that raise the average performance level.
This reflects a traditional strength of Japanese organizations: coordination, collaboration, and shared roles that elevate collective performance.
Conclusion | Strong Organizations Share Purpose and Choose Their Tools
Psychological safety is necessary for organizations to compete.
Without the ability to speak up or report problems, organizations cannot improve.
However, it should never be treated as absolute.
Psychological safety is a tool, not the goal.
The goal is organizational strength and growth.
If misunderstood, psychological safety can create organizations where no one criticizes, no one decides, and no one takes responsibility.
The key is not worshiping psychological safety itself, but using it appropriately in pursuit of shared goals.
A strong organization is one where everyone understands:
-
Why the organization exists
-
What it aims to achieve
-
What priorities guide its actions
Only when that shared understanding exists can standards, experimentation, dialogue, and psychological safety function properly.
Psychological safety is necessary—but it is not absolute.
It gains meaning only when used in service of organizational purpose and growth.
