I'll push back. Someone who knows a lot of (true) things demonstrates at least three hallmarks of intelligence. First, the ability to store and organize information. Second, the ability to discern fact from fiction when seeking out and integrating knowledge. Third, general curiosity, a desire to learn and understand things. Even if the person in question isn't the most quick-witted, they're definitely some form of intelligent.
