Mental Models: 30 Thinking Tools That Separate the Average From the Exceptional
by Peter Hollins
Thirty models (inversion, second-order thinking, Occam's razor, opportunity cost and the rest) explained in a few pages each with examples. It is an introduction for people who have heard the term and want the list, and it does not pretend to more.
Read it if…
you want a quick starter list of thinking tools.
Skip it if…
you want depth or rigour; see The Model Thinker.
Three things you will actually use
- Invert the problem to find the obvious errors.
- Think past the first consequence.
- Opportunity cost is the model most people forget.
Do this first
Apply inversion to one decision this week: what would guarantee failure?
Our verdict
A starter list, nothing more.
