Only limited
information can be
harmful. You might be hurt by the fact that
your wife cheated on you, but once you know exactly
why she did it, you might
understand and not be
as hurt. Assuming that any piece of
knowledge is bad for you presumes that you do not know how to
handle it, which would be due other lacking information. Essentially, if there is only one piece of information that you would know, yes, but if we're talking about this in the perspective of
omniscence, then no.
Tem42: it's called misinformation, if you knew all the information then you would disregard it as an opinion.
