Mental Models & First-Principles Thinking With AI

How advanced learners simplify complexity and make better decisions.

👋 Welcome to Issue #12 (Advanced)

In the last issue, we made a critical shift:

👉 from learning information
👉 to learning how to think

Now we go deeper.

This issue introduces the tools that experts use to reason clearly in complex situations:

  • Mental models
  • First-principles thinking

These are not academic ideas.
They are practical thinking tools used by engineers, scientists, strategists, investors, designers, and leaders.

With AI, you can now practice these thinking skills deliberately — not just admire them.

🧠 What Are Mental Models (Really)?

A mental model is a simplified explanation of how something works.

Examples:

  • Supply & demand
  • Feedback loops
  • Compounding
  • Opportunity cost
  • Constraints
  • Incentives
  • Systems thinking

Experts don’t memorize facts —
they apply mental models across many domains.

“The same few models explain most of reality.”

Vibe Learning teaches you how to build, test, and reuse these models with AI.

🔥 Why First-Principles Thinking Matters

Most people learn by analogy:

“This is like that.”

That’s useful — but limited.

First-principles thinking asks:

👉 What is this actually made of?
👉 What assumptions am I accepting?
👉 What cannot be removed?
👉 What must be true for this to work?

This approach helps you:

  • break out of surface thinking
  • avoid copying bad assumptions
  • reason independently
  • innovate instead of imitate

AI is extremely powerful when used this way.

Issue #12 helps you cross this boundary.

🧩 Using AI to Discover Mental Models

Instead of asking:
❌ “Explain this topic.”

Ask:

“What mental models explain how this works?”

Example Prompt

“Identify the key mental models behind how social media algorithms work.
Explain each model simply and show how it applies.”

You’ll start seeing patterns everywhere.

🧠 The Core Mental Models You Should Practice

Here are a few that show up constantly:

1️⃣ Cause & Effect

What actually causes outcomes — not what appears to.

2️⃣ Feedback Loops

Positive (amplifying) vs negative (stabilizing).

3️⃣ Constraints

What limits the system? (Time, energy, resources, attention)

4️⃣ Incentives

Why people or systems behave the way they do.

5️⃣ Tradeoffs

What you gain vs what you give up.

6️⃣ Compounding

Small actions → big outcomes over time.

AI can help you practice applying each one.

🧩 First-Principles Prompt Framework

Use this anytime you want deep understanding.

“Break this concept down using first-principles thinking.
Identify:
– core components
– assumptions
– constraints
– what must be true
– what can be removed
– what would fail first if stressed.”

This turns vague knowledge into structural understanding.

🌍 Real-World Examples

💻 Technology

Instead of memorizing tools, ask:

“What problem does this tool solve at a first-principles level?”

📊 Business

“What incentives drive customer behavior here?”

🌎 Learning

“What constraints limit my progress right now?”

🧠 Personal Growth

“What feedback loops reinforce my habits?”

✍️ Writing

“What mental model explains why this argument is persuasive?”

These questions turn learning into thinking practice.

🔄 The Mental Model Practice Loop

Use this weekly:

1️⃣ Choose a concept
2️⃣ Identify mental models
3️⃣ Break it down to first principles
4️⃣ Apply it to a different domain
5️⃣ Stress-test the model
6️⃣ Reflect on what changed

AI helps at every step.

✏️ Exercises — Train Advanced Thinking

🧪 Exercise 1 — Model Identification

Ask:

“What mental models explain how ___ works?”

List them.

🧠 Exercise 2 — First-Principles Breakdown

Pick one model and ask:

“Break this down to first principles.”

🔁 Exercise 3 — Cross-Domain Transfer

Ask:

“How does this mental model apply to a completely different field?”

This builds true mastery.

🎯 Exercise 4 — Decision Improvement

Ask:

“What decisions improve if I understand this mental model?”

📝 Exercise 5 — Teach the Model

Explain it in your own words — simply.

If you can teach it, you own it.

🚀 What’s Coming Next

In the next issue:

Learning Multiple Skills in Parallel (Without Confusion)

You’ll learn how to:

  • manage cognitive load
  • avoid context switching burnout
  • design parallel learning tracks
  • use AI to coordinate multiple goals
  • build synergy between skills

This is essential for modern, multi-skill professionals.
