Dowding, as the chief of wing flying scheduling at RAF Lakenheath, I "know things" that would improve operations at the base. But because of the way information must be filtered up through my boss, and because my boss does not trust how I got some of my info, there is no way I can present it to the senior base leadership. And that's for something that isn't really all that important, just the results of an efficiency study.
Analysis results must ALWAYS get filtered on the way to the top, and it's really not suprising to learn that the desire to give "the boss" the best, unambiguous set of data, certain alternate results were filtered out. That's what those lower level analyists are SUPPOSED to do, and their bosses are paid to filter the analysis upwards.
What people don't understand is that there is a lot of human judgement that goes into this sort of info gathering and analysis. That means that mistakes will be made. There is no way around this... It's not something you can turn over to a computer to do, and simply tossing it all out because errors will occur is just as bad because then you'll get no info at all.
