Design paper cuts are frustrating to me, because I feel like they compound to create an overall poor user experience. However, has there been any research behind how these oversights from a visual level affect a user's perception of an experience?
Personally, whenever I see something like heavy gradient banding anywhere these days, it gives me the feeling that the design is low-quality or heavily-compressed (even when it is not). Therefore, my perception of the quality of the experience is lessened.
Any formal insight into how these sort of things add up in a user's mind? To be clear, I am not necessarily looking for discussions about whether or not UX is improved by good visual design. I am more interested in any analysis that suggests how minor design mistakes can add up to create a perceived bad experience, even if the user might not be able to explicitly determine what is "bad."
