Collective knowledge of important, relevant things. But that is a small, constantly changing set of theories and knowledge. Inability to stop focusing on irrelevant details (ie, too much information intake) or inability to move on from no-longer-accurate information (ie, too good a memory) are both heavily involved with mental illness and psychiatric disorders -- and I think are causing society level mental illness, now.
