Does an MBA inoculate someone from making these judgment errors? If so, I personally know multiple MBA-holders who've made similar errors who should be informed that they deserve their money back or something. It's important to be aware of the necessity to perform those business functions that coders probably would rather not bother with, but once that happens, I find that technical people tend to make much, much better judgment calls than their business school superiors. In reality, it's rare to find people who're daring enough to apply simple rationality across most or all spectra, regardless of their background. Unfortunately, an MBA seemingly does very little to mitigate this, and it's the core problem. Yes, people could hypothetically learn, but most don't. I don't understand why we've all fooled ourselves into believing that four years of rote memorization and arbitrary compliance will do anything. I guess it being a much more fundamental problem is scary, because as simple as it may be, it's apparently quite difficult for most people to change. We have a big problem with our educational and hiring cultures.
