52 UX Cards to Discover Cognitive Biases

A few weeks ago, Laurence Vagner (with a V) and I gave a workshop in Paris Web. The theme was “cognitive biases”. We had already gave this workshop in English for our UX in Lux community in Luxembourg. For the French version of the workshop, we created a 52 UX cards deck to help people discover and understand different cognitive biases. This card deck is now available in English as well.

Cognitive biases are psychological thought mechanisms and tendencies that cause the human brain to draw incorrect conclusions. For better or worse, you can use them in many different ways to influence user behaviour in your products and services. These biases will also impact collaboration between team members and during meetings or might influencer your user research. Whether you are creating the user experience of an interfaces or purchasing something online, it’s interesting to be aware of these biases.

A deck of 52 Cognitive Bias UX Cards

The list of cognitive biases is long and might look downright frightening for many people. To make this easier to digest, Laurence and I selected 52 out of the list and organized them into 5 categories:

• Decision-making & behaviour
• Thinking & problem solving
• Memories & recalling
• Interview & user testing
• Team work, social & meetings

The icons for those categories come from Streamline, in case you where wondering 🙂

These cards were created  for teaching and learning purposes. They help team members become aware of their own biases and the different biases they can induce, whether on purpose or not, to users.  They can also be used as a cheat sheet and as “reminder cards” while designing. You can use them in small workshops with your coworkers to raise awareness among your team.

We have decided to publish the cards  under CC BY-NC-SA 4.0 license. You can print them directly on both sides. Do not print the first 4 pages unless you REALLY like our little heads illustrations.

An online list to help you

If you do not want the paper version, we have also prepared an online list. You can even add it as shortcut on your phone, yeahy. (I might eventually turn this into a PWA and have it work offline)

Online list of 52 selected biases

For more biases, you can visit the full list of biases extracted from Wikipedia. Kudos to Geoffrey for the code of those pages.

The Workshop

You will find the workshop process in the slides above and a short explanation on page 3 of the PDF. You can consult the presentation support of our workshop (the English version in Luxembourg, not the French one) here:

Some pictures of the workshop

Here are some pictures of our cards and participants working very hard to sell us a unicorn with as much bias as possible.

More cards, inspiration and ressources

If you want to go further here a few ressources:

• The “wikipedia list of cognitive biases“
• The scary Cognitive Bias Code from 2016 (which inspired us to build the English workshop in the first place)
• In our first English workshop, we used Cognitive Bias Cards For Learning Practitioners and mentioned  Sitback’s  UX Cards and also the github Cognitive Bias Cards. All of them inspired us to create the French version of the cards.
• Pocket Biases is a small Progressive Web app that also lists the biases and helps you digest them in a more easy way
• To have more fun there’s also a little online game with different biases.
