(I too appreciate thoroughness, but also believe that for some things in business “worse is better”. IE 90% thoroughness might cost 1/10th as much as 99% thoroughness, it’s certainly possible to over-index on the quality of the answers one provides)

> Why do the thorough people always have to empathize and not the other way around?
“Answers questions thoroughly” is a behavior, not part of a person’s identity. If someone gives you a partial answer, that may be optimal behavior for the circumstances, you don’t know, that’s where the empathy comes in. Of course empathy should be mutual, but you can’t be blocked on that to obtain a favorable business outcome. Empathy is a tool in your toolbox.
Maybe it's not entirely clear what I mean with thoroughness here. I am talking about not just ignoring someone's questions. It doesn't mean that if you "ask" me to answer 7 questions that will each take a day of work to answer that I will be "thorough and do those 7 things immediately to get you your answer". I will simply ensure that I read all your 7 questions and tell you that each will take me about a day to answer as it would require certain checks and that I do not have the time for that at the moment. However, if your questions are so urgent vs. the other things I have on my plate, you are welcome to talk to my boss/my product owner/etc on getting your items prioritized higher. I have a finite amount of time per day that I do work and while the exact amount can vary from time to time I will not start working 80 hour weeks or start ignoring your questions.
