Whereas it is definitely a good idea to stay up on ideas and opinions, I have long had an issue with so called "financial geniuses" who put forth lots of theories that don't actually hold up in tangible life.
Usually economists miss the point because they have models that are based around numbers that perhaps make sense in a vacuum where only calculations exist... but it all falls apart because they have close to zero understanding of human psychology.
I always felt it should be mandatory for economists and financiers to take a minimum of three years of human and industrial psychology as part of their education...
