You have said that before and I find that way of thiking, i.e. it doesn't matter if you are careless, quite incomprehensible. Obviously, strewn with mistakes and bad grammar it is not effective communication.
... but that is my point. If it communicates effectively, then it
is effective communication. Deficiencies of clarity, ambiguities etc. are a totally different matter - when they are present, it is not effective communication.
More worrying, and an ever-present risk, is that words can be written with perfect grammar, and written/typed (or pronounced) perfectly, but nevertheless convey information which is incorrect. As you go on to say ....
Cardiff is the capital of Scotland. Which is the mistake. You do not know and cannot tell.
Worse than "you don't know and cannot tell (which is the mistake)", if one didn't know better, one would have no reason to suspect that the statement contained
any mistakes, despite perfect grammar and typing.
Do you apply such sloppiness in your medical dealings?
Not a direct answer to your question, but I can tell you that if healthcare workers spent time correcting/educating patients in relation to their grammatical errors and misused technical vocabulary (except when there was ambiguity or lack of clarity), I feel sure that even less healthcare would be delivered than is currently managed.
I have said before, your view, though, only applies to mistakes you consider unimportant. Well, other people disagree.
As I said, I would consider a mistake to be "unimportant" as you put it (not interfering with effective communication) if I did not believe that it had impaired communication - and I suppose that others might disagree with me about that view. However, when it comes to things which are obvious typos, I would not expect much disagreement - were you seriously in any doubt as to the maning of anything that donmaico typed (badly) in this thread?
