Information that is acquired by searching for it (i.e. as an answer for a question) is often tainted by a desire for a particular answer that the individual may be unaware of. Information that is acquried with out such an intention is more likely to be free of such bias, and thus be more accurate (more true).
This could somehow be related to the process of knowledge acquisition, whereby in order to know a thing you must first be a thing, which obviously means that you cannot stand opposite the thing (in order to view it). How or why this is I don't know; it's just a hunch.
