It is a long time since I wanted to write about cognitive biases. I have been first made aware of it while reading this fascinating book “Thinking, fast and slow” by Daniel Kahneman (not a newbie, he won a Nobel prize), and with several blog posts or articles (references at the end). A list of all cognitive biases is available on wikipedia, but this is such a huge disorganized “tangled mess” that the task of writing about biases in Testing frightens me, and I have to admit that I procrastinated doing it. And then a blog post from Buster Benson (Product at SlackHQ) saved me. Thanks to his paternity leave, he decided to organize the mess and found four problems that biases help up to address: “Too much information”, “Not enough meaning”, “Need to act fast” and “What should we remember”. And now everything is almost crystal clear…at least if you go and read this.
An awesome visualization has been done by John Manoogian III and has been since added to the wikipedia page.
