I'd like to add that we often don't even care about the correctness of
content. Consider the web: I don't trust web servers to provide me
with correct data and I generally have no way to computationally
verify that the data is correct. Nevertheless, I find the web useful
with the caveat that the data may be either malicious or incorrect.
Thanks,
