Mental model of the week

What is a mental model?

A mental model is an explanation in our mind of how things work in reality. It’s a worldview that shapes how we think and understand the world.

The more mental models you have in your mind, the better your ability to think in new ways, solve difficult problems, and make better decisions in everyday life.

Great thinkers, problem-solvers, and decision-makers rely on a wide variety of mental models to simplify complexity and spot opportunities most people don’t see.

Mental models are imperfect, but useful to train your brain to think better.

What is inversion?

Inversion is a mental model used to avoid mistakes and uncover solutions to difficult problems by solving problems in inverse form.

It originates from the 19th-century German mathematician, Carl Gustav Jacob Jacobi, who made important scientific contributions by using the strategy “invert, always invert.”(loosely translated from ‘man muss immer umkehren.’)

How do I use it?

Step 1: Identify the opposite of your problem.

For example, let’s say you want to build healthy relationships. Consider the question: “How can I build toxic relationships?”

Step 2: Brainstorm solutions to the opposite problem.

For example, one way to build toxic relationships is to criticize others and dismiss their opinions.

Step 3: Avoid solutions to the opposite problem.

In our example, by avoiding different ways to build toxic relationships you can improve the odds of building healthy ones.

Key takeaway: Instead of focusing on being right, focus on being less wrong.
