A mental model is any concept that helps explain, analyze, or navigate the world. More importantly, for product managers, our mental models drive our decision making and our prioritization.
In his 1994 talk at USC Law School Charlie Munger, the investment partner of Warren Buffet, gave his opinion that for success, you must have multiple mental models. Different situations call for different mental models. If all we have is a hammer, then everything looks like a nail, and that's obviously a bad situation to be in.
There are dozens, if not hundreds, of mental models that can help you in different situations. In this talk I'm going to focus on a handful that I find most useful as a product manager.

7. Toolbox
If all you have is a
hammer, then you have to
solve every problem as
though it were a nail.
8. Toolbox
“80 or 90 important
models will carry about
90% of the freight in
making you a
worldly-wise person.”
If all you have is a
hammer, then you have to
solve every problem as
though it were a nail.

Hanlon’s Razor— “Never attribute to
malice that which is adequately
explained by carelessness.” Activation Energy— “The minimum
energy which must be available to a
chemical system with potential
reactants to result in a chemical
reaction.”

Hanlon’s Razor— “Never attribute to
malice that which is adequately

Scientific Method— “Systematic
observation, measurement, and
experiment, and the formulation, testing,
and modification of hypotheses.”

48. How To Use – Three Actions
1. Articulate your value proposition
• Four part framework – category, customer, benefits,
differentiators
• (This is hard - you might find yourself struggling. If
you’re struggling, imagine how your market is
struggling to understand why they should buy your
thing.)
2. What’s your product’s 10x thing?
• “Not only will you have 1/10 the downtime, but you’ll
implement 10x faster than with our competitors.”
3. Study up on mental models
• Constant learning gives you a leg up
• More tools = more problems you can solve
