Disclaimer: THIS HAS STRICTLY NOTHING TO DO WITH RACISM, AS I'VE ALREADY EXPLAINED. THIS IS STRICTLY ABOUT ECONOMICS. FOR THE SOCIAL ASPECT, SEE MY FIRST POST, AT THE BEGINNING OF THE THREAD. Calling people racist for disagreeing on a simple economic debate is completely dumb and off-topic.
It's true that some "scientific studies" are bogus. That doesn't make personal experience outweigh a statistical accumulation of data when it comes to seeing a tendency, though... if the sources are trustable (I'd say
Harvard Business Review is) and if their conclusions are backed by other sources (they are; I made my own research, and realized I ended up reading the articles Oops had already linked), then you at least have to consider them lol. If your reasoning about "it seems unreasonable due to my personal experience, therefore it's necessarily fake, no matter the study" was correct, quantum physics would be to dismiss completely. After all, you can absolutely measure both speed and location of objects around, so how could objects possibly be made of things that do not have that property?
I kinda implied it, but didn't clearly express it, I guess.
It's logical that a culturally diverse team would perform better than an homogeneous one: multiple cultures imply multiple views, which lead to multiple reasonings; this is what the Harvard study is talking about when it says "thinking outside the box". It prevents intellectual inbreeding.
It's quite obvious someone without an elementary education won't be fit to lead a business, no matter what his culture may be xD. I don't think anybody was arguing against that.
