A Cognitive Bias, Mental Model or Dark Pattern explained every time you open a new tab to help improve your decision-making process.


What can I learn about?

To begin with, we cover Cognitive Biases, Mental Models and Dark Patterns but we’ll add more subjects as we go through our journey.

Why did we pick these? Well, we started this project by learning about Cognitive Biases. While it’s all well and good to be aware of our biases, we believe that Mental Models give us an easy to follow framework to react to these biases. Dark Patterns is something we became interested more recently and, same as Cognitive Biases, we believe it is important to recognise them.

Cognitive Biases

Based on the Cognitive Bias Codex print from DesignHacks.
We researched the definitions of each bias and added a few must-read recommendations.

Dark Patterns

Based on 'Dark Patterns at Scale: Findings from a Crawl of 11K Shopping Websites'. An ever-growing list of patterns designed to make you buy stuff.

Mental Models

A curated list of over 300 mental models from various books and sources to help you make better decisions. Each comes with a recommended read.


Great, so learn all this and I'll be able to make better decisions, right?

If only it were so easy. The bad news is that you'll probably never become that bastion of rationality you'd like to. The more you learn, the more you think you know better and, sadly, your biases will still overcome you some times.

You should, however, develop your critical thinking skills; you should identify more biases in yourself and occasionally be able to correct them. That has to be a win, right?


An amazing idea and and great execution! The ability to self-examine, and identify our own biases and change our habits is a superpower. This chrome plugin makes it easier than ever before.
