Since its founding in 1636, Harvard University has strived to instill this one ability in its students.
Over the past 150 years, argumentative writing programs have further spurred efforts to develop and develop this skill.
This ability is the ability to think critically, or 'critical thinking'.

In an age of information overload, where information overload is overwhelming and our minds are constantly working, and where the fake, the real, the false, and the actual are cleverly mixed to cloud our judgment, the foundation of thinking is critical thinking.
Critical thinking is the conscious thought process that produces meaningful results as intended.
Critical thinking is a high-level thinking ability that is only possible when the detailed thinking skills of "critical thinking" that rationally reviews and filters the supporting information, "reflective thinking" that monitors and controls the overall thought process, and "metacognition" that examines and checks oneself that leads all of these processes are in operation.

A closer look at the research findings reveals that writing enables critical thinking and reflection, generates new ideas and solutions, and effectively communicates your thoughts to others.
So, as a result, the possibility of success is bound to be high not only during academic studies but also after entering society in the future.

Thinking for yourself, thinking for yourself, does not in itself guarantee that you will produce desirable results.
Desirable thinking requires a conscious process of thinking beyond just thinking for oneself to produce meaningful results that align with one's intentions.
This is the level of thinking power as a living force.
As Nobel Prize-winning biologist Christiane Nüsslein-Volhard said:
The courage to think is the basic condition for excellence.
“Many people do not dare to think.
“You need to stop listening to other people’s stories too much and have the courage to make your own decisions and think for yourself.”
--- p.57, from “From a person who thinks for himself to a person who thinks properly”

Socrates is famous for his method of teaching, where he asks appropriate questions to his students instead of teaching them directly, and the students answer the questions and come to their own understanding.
This method is central to critical thinking and continues to be a key technique for promoting and encouraging critical thinking.
By listening to Socrates' questions, answering them, being asked more questions, and seeking answers, Steve Jobs may have wanted to gain insights that no one else had thought of.
And you would want to reflect that insight in your skills and business.
--- p.67, from “Why did Steve Jobs want to meet Socrates?”

Critical thinking is the conscious process of forming thoughts to produce meaningful results that are in line with your intentions.
The engine of critical thinking needs fuel to analyze and understand problem situations and make informed decisions.
Fuel is a diverse and specific set of data, and critical thinking is the process of developing evidence-based ideas based on this data.
Problem situation → Critical thinking → Solution
--- p.74, from “We must be able to produce the results we intend”

Critical thinking skills have long been emphasized for their importance and have become a killer question in various employment tests.
The college entrance exam Korean language test, TOEIC, PSAT, and Law School Admission Test, which require students to read a passage and answer the question using inference and critical thinking, were introduced a long time ago.
Even the 9th-grade civil service exam, which will be implemented in 2025, will assess critical thinking skills to gauge the actual job competencies required for civil servants.
--- p.80, from “New Requirements in the Age of Information Overload: High-Dimensional Thinking”

The reason fake thoughts are created is because we think that thinking is about repeating what we read, heard, and saw, copying other people's thoughts and writings, and patching together what we think is good.
Because I didn't think of it with my own head, I didn't realize that I was stealing someone else's thoughts.
It's proof that you don't know how to think critically.
So, what he says or writes is what others have already said or written, so it is naturally trite and ordinary.
Then, of course, it will not be conveyed or communicated to the other person.
--- p.151, from “So what do you think?”

The 3-Challenge Format method promotes critical thinking.
Like the critical thinking routine "See, Think, Wonder" suggested by Harvard Project Zero, it helps you closely observe and analyze objects, reflect on your thinking process, and think more delicately and sophisticatedly based on this.
The 3-Challenge Format Thinking Method is a thinking tool that naturally reflects the three thinking skills that make up a critical thinking routine: thinking critically, thinking reflectively, and thinking about oneself.
--- p.157, from “Harvard Students Think Three Times”

Critical thinking and innovative thinking are never achieved in one shot.
When I carefully observe something (observe), capture the feelings and thoughts that arise in relation to it, and connect it with some knowledge and thoughts that I have stored (reflection), and in the process, fragments of thoughts come together and disperse, a spark occurs, and finally an 'Aha!' moment occurs (insight).
By staying in this slow process (critical thinking routine), I become aware of what I feel and think, what I know and don't know, and what I am doing and for what (metacognition).
This is the characteristic and effect of the 3-shot format thinking method.
