A “No” answer by itself implies one of two longer answers; either “No, and you should already know why not” (i.e.: “Hey, do you want to rob that bank with me?”), or “No, and I don’t owe you an explanation” (i.e.: “Do you want to go out sometime?”) I feel like in a work context, ‘no’s really need more of an explanation than that in most cases (with obvious exceptions if a request is wildly inappropriate or unethical). For work-related questions from folks higher up than you, a ‘no’ is a chance to give them more of a view of what’s going on in the trenches, and for those lower than you it’s a chance to mentor them and give them a wider view of the work, helping lift them up a little closer to your own level. And either way, that explanation for the ‘no’ is where all the value of the communication is coming from. If you don’t give the longer explanation immediately, it leaves the asker questioning whether you meant the “and I don’t owe you an explanation” or the “and you should already know why not” version of “no”. Neither of which is great for maintaining cordial work relationships.
