A tangential nitpick: Scientists, Engineers who are not of the Software persuasion, Accountants, and Lawyers, to name just a few, also make up people who work "outside the SWE field". Almost all of these people are interested in thinking; a few of them will probably not be, just as one finds a few people working in the SWE field being reluctant to think. There is a very good reason why people -- even technically minded people -- have trouble with changing UIs, and it is not about them not wanting to think. Consider that the UI could be part of a workflow that is more of a side annoyance than their main job, and that they would rather conserve their mental bandwidth for problems that are more important to them. A doctor shouldn't have to get used to a new timesheet UI just because a designer woke up one fine morning with a new thought.
