Intelligence Isn't Genetic: A Complete Guide to Thinking Methods That Set You Apart at Work

"That person is so smart."

Have you ever had that moment?

The person who says exactly the right thing in a meeting.

The person whose explanations are easy to understand.

The person who just sees things differently.

Is it because of their elite education?

Is it because they are fast at mental math?

It's neither.

It's simply whether they can freely move between "Concrete" and "Abstract" thinking.

You might wonder, what is concrete? What is abstract?

To put it very simply:

• Concrete = Explaining in detail
• Abstract = Summarizing roughly

People who can switch between these two depending on the situation are the "capable people" in both the workplace and personal relationships.

Since I started being conscious of this, my verbalization in SNS management changed,

my way of communicating with followers changed,

and my work speed increased.

Today, I'm writing down all of these thinking methods.

Chapter 1: Why Your Explanations Don't Get Across

Have you ever been told to "speak more concretely"?

I have. My boss told me many times when I was a newcomer.

I would try my best to explain things in detail, but for some reason, it would just lead to them asking, "So, what's your point?"

And that's natural because true "concretization thinking" isn't just about explaining things in fine detail.

It's the "ability to take an abstract concept as a starting point, break down the elements, and perceive them vividly."

There are actually four types of this concretization thinking.

① Decomposition Thinking: Increasing Resolution to the Limit

For example, the phrase "I want to make an eco-friendly product."

You kind of get it. But you can't act on just that.

This is where you use decomposition thinking.

"Materials" → Use renewable ones

"Design" → Make it long-lasting

"Disposal" → Make it easy to recycle

By breaking it down from top to bottom, you finally see "what to do next."

It's the same with marriage hunting. You can't act on just "I want to marry a good person."

"A kind person"

↓

"Someone who follows up when I'm feeling unwell"

↓

"Someone who replies to LINE messages quickly"

Once you decompose it this far, you finally have criteria to judge a partner.

② Difference Thinking: Finding Your Strengths by Discovering "Differences"

People who think "I have no strengths" are lacking this.

Difference thinking is the power to highlight features by making the differences from others stand out.

For example, if there are five people at a mixer saying "My hobby is weight training," they all blend together.

But if a very muscular person says "My hobby is reading," it leaves an impression.

It's exactly the same on SNS.

Instead of "I'm an office worker who wants to earn from a side hustle,"

"I'm a former nurse and office worker with 40 million yen in assets"

differentiates you instantly.

What is "normal" to you is often "rare" to others.

Finding that is difference thinking.

③ Analytical Thinking: Drawing a Map to Solve Problems

Analytical thinking is a combination of decomposition and difference thinking.

"The power to separate elements and understand their relationships."

If you're stuck thinking "I'm just busy" when work and chores aren't getting done, nothing will change.

Decompose housework into "Cleaning, Laundry, Cooking."

Separate them into "Daily tasks" and "Weekly tasks."

Compare this with how you use your time in a day.

Just by doing this, you can see what is truly necessary and what is a waste.

People in the workplace who "always seem busy but don't produce results" usually fail at this analysis.

They keep spending time on unimportant things.

④ Estimation Thinking: The Power to Form Hypotheses for Unanswerable Questions

This is a technique called "Fermi Estimation" in consulting.

The power to form logical hypotheses using only the knowledge you have on hand without looking things up.

For example, if asked "What are the sales of this cafe today?"

30 seats × 3 rotations × 800 yen unit price = 72,000 yen.

You can calculate it like that.

Rather than whether the answer is correct, the habit of proceeding with a hypothesis is important.

Once you master this, you won't stop because "there's no data" or "there's no precedent."

Chapter 2: "Abstraction Thinking" That Raises Your Perspective

If concretization is "digging deep," abstraction is the task of looking at the whole with a "bird's eye view."

You become able to find essences and patterns within scattered information.

There are also four types here.

① Commonality Thinking: Finding the Seeds of Ideas

"Minato Ward, Saitama Prefecture, Kyushu." What do these three have in common?

• "They are in Japan"
• "They are place names"
• "They contain Kanji"

This is training to find commonalities in seemingly disparate things.

If you can do this, you can apply success stories from completely different industries to your own business.

In terms of SNS, extracting commonalities from viral posts and applying them to your own genre is exactly this.

② Classification Thinking: The Power to Organize Information

How would you classify "Butterfly, Vacuum Cleaner, Turtle, Bed"?

Living or non-living.

Moves or doesn't move.

Large or small.

There is no right answer.

But the habit of "organizing by your own standards" increases the speed of information processing.

People whose heads are a mess often fail at this classification.

They are in a state of just taking in information without organizing it.

③ Point Thinking: A Way of Speaking That Communicates Instantly

People who are told "What's your point?" are weak in point thinking.

The power to say "In short, it's XX" in one word.

The task of thinking of email subject lines is the best training.

Instead of "About the dinner party," someone who can write "Dinner party on [Date] at 20:00: Request for attendance confirmation" has a completely different way of communicating.

It's the same with LINE; someone who can send just the main point briefly gives a more "capable" impression than someone who sends long, rambling messages.

④ Law Thinking: The Power to Reproduce Success

The power to find commonalities among successful people and extract them as laws you can use.

If you look at commonalities among "people who get high-quality sleep":

• Refrain from caffeine after the evening
• Naps are within 20 minutes
• Stop using smartphones before bed

People who can verbalize this not just as a "personal rule" but as a "law anyone can use" will produce results in any field.

Chapter 3: Thinking Methods for Those Who Won't Have Their Jobs Taken by AI

Logical thinking is important.

But thinking that derives 1+1=2 is, honestly, already faster and more accurate for AI.

What is needed in the coming era is:

• The power to dare to give an answer different from others,
• The power to form your own hypotheses for unanswerable questions.

People who can move between the concrete and the abstract can switch their thinking according to the person and situation.

I believe this is the true intelligence for surviving the AI era.

Chapter 4: Brain Training Habits You Can Do in 2 Minutes Starting Today

No difficult study is required. Small daily habits are fine.

1. Decomposition Drill: Instead of saying "I like cooking," break it down to "I like the process of sautéing onions until they are caramelized."
2. Difference Drill: Ask "Why is that person popular?" and look for specific differences compared to yourself.
3. Point Drill: Try giving today's work a one-word title.
4. Estimation Drill: Try calculating today's sales of the cafe in front of you from the number of customers and unit price.

Finally,

When you become able to move between the concrete and the abstract:

• Work becomes faster.
• Explanations get across.
• Friction in human relationships decreases.

Above all, you stop being afraid of a "world without correct answers."

Intelligence is not innate. It truly changes just by changing your thinking habits.

First, try thinking about "what you want to say in short" before sending a LINE or email today.

That's all it takes.

In my 4 years of SNS management, I have always been conscious of this use of concrete and abstract.
