Cognitive Bias — Part 1

Cognitive Bias Part 1 — UX Knowledge Base Sketch #35

Why knowing about cognitive biases is important?

Cognitive Psychology and UX design are two closely related fields: users apply their cognitive functions during their interaction with digital products (services).

Cognitive biases are shortcuts, distortions in our perceptions, parts of our cognitive activity. The important thing to understand here is that biases are not necessarily bad: as Rüdiger F. Pohl expresses in his book, Cognitive Illusions:

“The question of whether a decision, judgement, or memory is “correct” (in a normative way) is usually secondary to the question of whether that decision, judgement, or memory is helpful in the current situation.”

So by understanding the effects of the most relevant cognitive biases, we can improve user experience not only by trying to avoid the possible negative consequences, but also by taking advantage of them!

Another significant aspect is that we, designers also have cognitive biases, so we need to pay attention to these during the research and design process.
