I thought that this video, published in May 2018, was somewhat interesting and I am sharing it in case others are also interested. The presenter uses a change of design of Wikipedia's front page search box from 2010 (see https://blog.wikimedia.org/2010/06/15/usability-why-did-we-move-the-search-…) as an example, though I would hope that the lesson from this video isn't that it's okay to frequently disrupt the workflows of existing users with design changes regardless of the amount of complaints from existing users. The main points that I drew from this presentation are that interfaces should be intuitive and should have relatively light cognitive load. Those points may sound obvious to experienced UX designers, but may be of interest to people whose areas of expertise are in other domains. I also appreciated that the presenter shared an example of a situation in which people said one thing in surveys but behaved in the opposite way in practice.
