Analysing your IQ

A claim is only meaningful if it can be proven wrong. Unfalsifiable claims are useless.
Falsifiability isn't just theory—it's a practical framework for better decisions. This page explains how it works and how to apply it.
Ask "What would convince me I'm wrong?" If nothing would, your belief isn't based on evidence.
The power of Falsifiability comes from its ability to compress complexity. A good mental model acts like a lens—it brings the important features into focus.
"The universe was created 5 minutes ago with fake memories" cannot be disproven—and is therefore meaningless.
Use Falsifiability when facing complex decisions with multiple variables. It's especially powerful when conventional wisdom seems wrong or when you're operating in unfamiliar territory.
Over-applying: Not every problem benefits from this model. Match the tool to the situation.
Under-applying: People learn the model but don't practice it. Application takes repetition.
Misunderstanding the principle: Surface-level understanding leads to poor execution. Study the examples.
Ignoring context: The same model works differently in different domains. Adapt accordingly.
Identify a current decision you're facing. Write down the assumptions you're making. Challenge each one.
Look at a past failure. Apply Falsifiability retroactively—would it have changed the outcome?
Teach the model to someone else. If you can't explain it simply, you don't understand it well enough.
Set a reminder to apply this model once per week for the next month. Track the results.
No single model handles every situation. Build a toolkit of complementary frameworks.
Mental models require specific cognitive traits to execute. Do you have the Intelligence for this?

"The universe was created 5 minutes ago with fake memories" cannot be disproven—and is therefore meaningless.
Use Falsifiability when facing complex decisions in the reasoning domain, when conventional approaches aren't working, or when you need a structured framework for analysis.
Falsifiability is used by strategic thinkers, business leaders, and anyone who needs to make high-stakes decisions under uncertainty. It's particularly popular in investing, startups, and engineering.
Yes. Mental models are learnable skills, not innate talents. The key is deliberate practice—actively applying the model to real decisions, not just reading about it.
