Critical Thinking Made Simple: The PEG Framework
[5 min] [Impact 92]
How clear thinking actually works — when decisions matter
For leaders, managers, and professionals who need to make smart decisions under pressure.
Great decisions rarely come from faster thinking. They come from better lenses.
PEG Critical Thinking
A simple framework that helps you evaluate ideas before making a decision.
Don’t memorize theories. Remember the lenses.
Perspectives → Who sees this differently and why?
Evidence → What are the facts vs assumptions?
Gaps → What do we not know yet? What could break this?
A simple way to explain clear thinking
Let me explain this in a simple way.
Imagine you're about to take a picture with your phone.
Most people think it’s just point and shoot.
But you actually do three things—almost automatically.
First, you move.
You step left or right.
You change the angle.
Why?
Because you’re looking for a better perspective.
Second, you focus.
You tap the screen.
Now the image becomes sharp.
You see what’s actually there.
That’s your evidence.
Third, you check the frame.
You quickly look around the edges.
Is something missing?
Is everything important included?
That’s where you spot the gaps.
Only then… you press the button.
Before you press the button—on a photo or a decision—check the three lenses.
The 10-second PEG decision check
Before making an important decision, pause for a moment and run three quick checks.
- Perspectives — Who sees this differently—and why?
- Evidence — What are the facts vs assumptions?
- Gaps — What could break this?
Before you press the button on a decision, check the three lenses.
Perspectives. Evidence. Gaps.
The uncomfortable truth
Most bad decisions are not caused by bad intentions.
They come from incomplete thinking.
- Too few perspectives
- Weak evidence
- Hidden gaps
When one of these is missing, judgment collapses.
Science behind it (why this works)
PEG reflects how strong decision-making actually happens in psychology, intelligence analysis, and strategic thinking.
- Bias reduction (Kahneman & Tversky): Considering multiple perspectives helps counter common cognitive biases like confirmation bias and overconfidence.
- Evidence-based reasoning: Separating facts from assumptions improves judgment and reduces decisions based purely on intuition or opinion.
- Red-team thinking: Actively searching for gaps and counterexamples is a core technique used in strategy, intelligence analysis, and risk management.
Strong decisions come from three habits:
seeing multiple perspectives,
testing the evidence,
and searching for what might be missing.
The three lenses of PEG
1️⃣ Perspectives
Ask who sees the situation differently- and why?
- Sales
- Finance
- Customers
- Operations
Different perspectives expose hidden assumptions.
2️⃣ Evidence
Separate facts from opinions.
- What are the facts vs assumptions?
- What evidence contradicts this?
- How reliable is the source?
Evidence grounds decisions in reality.
3️⃣ Gaps
Look for what’s missing.
- What could break this?
- What don’t we know yet?
- What would prove us wrong?
Great thinkers actively search for blind spots.
Three quick examples
Perspectives: Sales vs product vs customer success Evidence: churn data, adoption metrics Gaps: unknown behavior in new markets
Perspectives: hiring manager, team members, HR Evidence: past performance data Gaps: cultural fit uncertainty
Perspectives: internal teams vs customers Evidence: market data Gaps: competitor response
If you remember only one sentence
Look around. Test the facts. Check what’s missing.
They pause for one moment and ask:
What perspectives are missing? What are the facts vs assumptions? What could break this?
