Cognitive biases are psychological tendencies that cause the human brain to draw incorrect conclusions. For better or worse, we can use them in many different ways to influence user behavior on your websites and apps. Definition

“Other people booked it, maybe I should book it too” (Bandwagon eﬀect) 🦄

Slide 12

Slide 12 text

As designers (and as customers), it’s also interesting to be aware of such biases. For instance, some of them might inﬂuence your user research without you even knowing it. Deﬁnition

Slide 18

Slide 18 text

Slide 22

Slide 22 text

Slide 26

Slide 26 text

Memories & recalling These biases can inﬂuence choices by either enhancing or impairing the recall of a memory or altering the content of a reported memory. 🦄

Slide 27

Slide 27 text

Primacy eﬀect Items near the end of a sequence are the easiest to recall, followed by the items at the beginning of a sequence; items in the middle are the least likely to be remembered.

Slide 28

Slide 28 text

Bizarreness eﬀect Bizarre material is better remembered than common material. 🦄

Slide 29

Slide 29 text

Interview & user testing These biases can directly inﬂuence designer, during interviews or user testing, and may change the outcome of our research. They inﬂuence the behaviour of people we interview or people who will test your products and services.

Slide 30

Slide 30 text

Courtesy bias The tendency to give an opinion that is more socially correct than one's true opinion, so as to avoid oﬀending anyone.

Slide 31

Slide 31 text

Negativity bias Psychological phenomenon by which humans have a greater recall of unpleasant memories compared with positive memories.

Slide 32

Slide 32 text

Slide 33

Slide 33 text

"Not invented here" NIH Aversion to contact with or use of already existing products, research, standards, or knowledge developed outside a group because of their external origins and costs, such as royalties. Research illustrates a strong bias against ideas from the outside.

Slide 34

Slide 34 text

Reactance The urge to do the opposite of what someone wants people to do out of a need to resist a perceived attempt to constrain their freedom of choice or limit their range of alternatives. 🦄

Slide 35 text

How to use the cards? 02

Slide 36

Slide 36 text

These cards were created for teaching 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. The goal

Slide 37

Slide 37 text

Step 0 - Download the cards and cut them > inpx.it/52-cards 🦄

Slide 38

Slide 38 text

Step 1 - Discover and recall 1. Discovery Distribute the cards to groups (or individuals). Ask the people in the group to work together to recall examples of projects, interfaces or work related situations where they might have faced those biases. Before they start, remind them that they will need to pick 2 to present and pick a presenter. (10 minutes) 🦄

Slide 39

Slide 39 text

Step 1 - Discover and recall 2. Sharing Each group presents 1 or 2 of the biases with an example to all participants in the workshop. At the end of the sharing session, depending on how many groups, people “know” at least 10 biases. (2-3 minutes per group) 🦄

Step 2 - Build an experience 1. Let’s be evil! The people in the group (or individuals) will now imagine the most manipulative experience possible. They need to use as many biases as possible: those from the cards, those they already know. You can ask them to build an interface, but also a non-digital experience, or even make an advertisement, a TV spot, etc. Before they start, remind them that they will need to pick a presenter to present the evil experience (15/20 minutes)

Slide 42

Slide 42 text

Step 2 - Build an experience 2. Sharing Each group then presents their own evil experience by listing the diﬀerent biases used. Count the points and discover which group is the most evil and manipulative! (2-3 minutes per group)

What about remote workshops? 🦊 ● A conference tool with voice, a chat and breakout rooms to split people into groups. ● A board tool (like Miro or mural) with the cards on it. ● Icebreaker to help people get comfortable with remote tools.

Ethics So, good or evil, what you create and build is your responsibility and your choice. Would you use some of those in a project?
