Assume you are wrong until proven otherwise. There are really quite a lot of constraints you are at most times not qualified to reason about. Small example: I was working on implementing accessibility for a government website and was rather baffled at the requirement to provide sign language videos providing basic explanations. I had assumed we'd need to provide augmenting accesibility, i.e. text-to-speech for the blind. In my mind, if a person can see, they can also read. Turns out: no, not the case. Sign language is a separate language and you'd be learning your locally dominant language as a first foreign language, so depending on the community you grow up with, you may as well lack basic literacy in that language. Therefore, sign language videos are more akin to offering the website in different languages that assistive technology. After that incident, I've learned to assume there is always something I don't know which explains the things I find weird.
