Importance of Knowledge, Perspectives, and Intelligence in Finance

Hey guys,

So I know finance (IB/PE mostly) is known for being not particularly intellectually stimulating and requires mental stamina / social skills above raw IQ. 

I'm curious though as to whether you think "expanding one's mind" and developing different ways of thinking through learning about subjects outside of just business/finance/math in university (like sociology, psychology, history, etc.) better equips you for a long term career in finance. 

Obviously at the lowest levels where you're just making excel models and formatting PPTs this wouldn't matter at all, but could it have some relevance at higher levels? Which industries/careers within finance would this be more relevant in?
