Having reviewed the first few pages of this thread, a hat tip to Steve Tonks for providing the clue as to where our thinking should have gone, and a glass of champers to Silverstrata at post 118, for listing the actual problem (control restriction) together with some possible sources of said restriction.
For the rest of us, responsible for producing multiple pages of speculative tosh, I recommend Thinking Fast, Thinking Slow by Daniel Kahneman. It will tell you exactly why all humans (yes that means you!) are pre-programmed to make bad judgements all of the time.
It's what we do.
