No: if I can add things I do - but I must not add anything. For example: I know loads of stuff because of my job, but I cannot give you a source at once that confirms it - if I must research for that source to contribute I simply will not contribute, since I have only a certain amount of time. Someone else who knows a source that confirms it can add it - otherwise: well you will need to rely on what I learnt during the past 40 years ... Whoever believes without asking in something written ... well ... if I do a research on a certain topic I do not only believe what is written in one encyclopaedia (take Brockhaus and Treccani - they sometimes differ a bit), but I have a look at other sources as well ... so what I learnt comes out of reading many, many books, letters, questions and answers, e-mails, websites, notes, whitepapers and whatever - all is somewhat related and confirmed. I know that I can rely on it - certainly I am not even able to research again all what I learnt only during the past 10 years (and I am not willing to do it - it would be like saying to a professor: when you give lessons you need to show me where you learnt your lessons and where what you say is confirmed).
