This paper investigates how the complexity of the world affects the reliability of opinions. A model of opinion formation is presented, where an uninformed observer forms opinions about subjects interconnected by a signed network representing trust and distrust. The study shows that the observer's opinions are highly inconsistent and unstable, with this inconsistency and instability increasing with world complexity (number of subjects and interactions). However, this increase can be mitigated by expanding the observer's initial information.
