I have been in too many large organizations (US Army-20 years) (State of Oregon- 12 1/2 years) where the focus was on what the boss or the boss's  boss on up through the chain wanted to hear; not whatever scintilla of 'truth' might actually exist, to 'trust' any final product that comes from any large bureaucracy.

When you add in institutional protection of egos, resources, and  funding, 'truth' is even more unlikely to be the most  important criteria.  

Since much 'analysis' is really opinion, 'truth' is truly illusory.

With the number of intelligence agencies now numbered in the teens, all of whom have concerns in all those areas, and then you get the cross fertilization as an NSA guy goes over to DIA and an Arabic specialist moves over to the Secretary of State and then someone else comes out of the COMSEC side or the CIA or the covert military side, it then becomes more of a Ben Franklin effort; "Gentlemen, we must hang together or most assuredly we shall hang separately!"
