Actually I have a pretty typical view, relative to folks who have to direct experience with human factors, UI/UX, cognitive, memory and attention models, and the like. And as I said, I made a point of testing my summary judgement with a group of real experts, last summer. My preference is to do design that accepts the realities of the operational context for the design. So, for example, a design that makes inappropriate demands on end users will fail. Humans are erratic in paying attention. Humans are typically quite poor at understanding computer security models. Humans are inconsistent in making decisions during real-time interactions. etc., etc. To repeat, my comments on this are not in the least controversial amongst folk who study such things. d/ -- Dave Crocker Brandenburg InternetWorking bbiw.net _______________________________________________ dmarc mailing list dmarc@ietf.org https://www.ietf.org/mailman/listinfo/dmarc
