TOCU. Test Observe Compare Update

 Here are five core ideas behind evidence-based thinking (as discussed by people like Helen Pearson and Eric Topol), translated into very practical, everyday decisions:

🧠 1) Don’t trust intuition alone →

Test small before committing

Idea: Human intuition is often confident—but wrong.

Daily translation:

• Before making a big change, run a small experiment

Examples:

• Thinking of a new diet? → Try it for 2 weeks, track energy/mood
• New productivity method? → Test it for a few days before adopting

👉 Replace:

“This feels right”
with
“Let me test this in a low-risk way”

🔍 2) Look for outcomes, not intentions →

What actually worked?

Idea: Good intentions don’t guarantee good results.

Daily translation:

• After doing something, ask:
• Did this actually help?

Examples:

• Meditation → Are you calmer over time, or just “doing it”?
• Exercise → Is it improving strength/energy, or just routine?

👉 Replace:

“I’m doing the right thing”
with
“Is this producing the result I want?”

⚖️ 3) Be willing to update →

Change your mind quickly when needed

Idea: Strong beliefs should be easy to revise with new evidence.

Daily translation:

• Treat opinions as temporary hypotheses

Examples:

• “I work best at night” → test mornings for a week
• “This person is difficult” → look for disconfirming evidence

👉 Replace:

“This is how it is”
with
“This is my current best guess”

📊 4) Compare, don’t assume →

Try A vs B

Idea: You can’t know what works without comparison.

Daily translation:

• Run simple A/B tests in your life

Examples:

• Coffee vs no coffee → compare focus for a week each
• Phone in bedroom vs outside → compare sleep quality
• 30 min work vs 60 min work blocks → compare output

👉 Replace:

“This seems good”
with
“Is this better than the alternative?”

🧩 5) Context matters →

What works for others may not work for you

Idea: Evidence gives averages—not guarantees.

Daily translation:

• Personalize everything

Examples:

• A diet works for many → but does it suit your body?
• A productivity system works for others → does it fit your work style?

👉 Replace:

“This works”
with
“Does this work for me, in my situation?”

🪶 Simple mental model to carry

Test → Observe → Compare → Update

That’s evidence-based thinking in action.

🔗 Connecting back to your earlier themes

• Gita 18.22 → don’t mistake a part for the whole
• Kashdan → stay flexible
• Bhurishaya Bhairava → reality is vast and not captured by one view
• Pearson / Topol → keep checking your views against reality

👉 They all converge on one principle:

Don’t freeze your understanding—keep it alive and revisable

If you want, I can turn this into a very simple daily 5-minute routine so it becomes automatic rather than something you have to think about.
