Why learn mental models?
Mental models are frameworks that help us understand complex systems and make better decisions.
Most PMs don't lack skill or drive.
They lack time.
Time is the one resource you can’t get more of — no matter how smart, senior, or scrappy you are.
So what separates good PMs from great ones?
Leverage.
Leverage doesn’t mean working harder. It means building systems. Using better tools. Thinking in frameworks, not from scratch.
The best cognitive tools we know of?
Mental models.
Mental models are how you work smarter. Prioritize faster, make clearer decisions, and lead with confidence — especially when everything is on fire.
They’re not just abstract concepts. They’re thinking infrastructure.
And if you don’t have that infrastructure, your brain becomes the bottleneck.
Dexter helps you build that — in minutes a day.
They're like cognitive shortcuts that successful leaders use to to go from chaos to clarity quickly.
Example:
Consider Amazon's product development process. Instead of starting with features, they use a mental model called 'Working Backwards'.
They write a press release and FAQ first — imagining the finished product's impact on customers. This forces clear thinking about product value and customer outcomes before diving into solutions.

Great Thinkers on Mental Models
“You can train your brain to think better. One of the best ways to do this is to expand the set of mental models you use to think.”
