Thanks for your critique, Dhruv! Can you explain more why you think task success is least important? My hypothesis would be that if a user can successfully complete important task to reach their goal it would positively impact their experience. Task success could then be scaled for major tasks across the entire product, and used as a benchmark metric for UX.
I wasn’t calling bullshit but I wanted to see if you know of evidence that this is true. Roel Willems pointed out a great example from Kahneman’s work. Really like your work, Arjan. Keep it up!
Thank you Roel for the example. It reminds me to look again into Daniel Kahneman’s work on judgement and decision making. We can probably find a lot of evidence on human biases that let us believe our intuition when we shouldn’t.
Thank you for a thought-provoking article! But if you take your above statements literally, we will begin with a decision we may already support, and look for the evidence that backs us up. What about starting with the good old research question, research goal, or hypothesis?
Great article Jason! Even though it’s been known for a long time, many people still seem to think people can explain and predict their behavior. Apart from that, I do think that interviews are a good method to understanding “who your users are” to help build empathy in an organization, which is very valuable to inspire creators to make great products.
