Corporate BS is the topic I want to study if I ever pursue a PhD. Not only BS that is directed from the top down, but also BS from the bottom and laterally. I'm curious what in corporate culture allows it to grow and what slows it. I also wonder if it's always bad or if it's beneficial in small amounts.

Anecdotally I have seen BS used to delay or avoid making commitments. BS can mask someone's lack of knowledge, or lack of execution. Middle managers seem to be the position to squash or spread BS. They often have a hard time detecting BS because they are too far from the work. When I think back to the best Directors and skip-level managers I have had in my career, they were all great BS detectors. They didn't let smooth talkers in their organization rise based on BS alone. They didn't let dependencies wriggle out of their commitments based on BS.
