A very interesting phenomenon, and one tends to refine one's 
understanding of it when thinking about developments in financial 
markets, because then it's serious and one has one's career at 
stake in learning to understand this phenomenon better.

There's a great deal of insight in Dr Iain Mcgilchrist's The 
Master and His Emissary.

What I think is happening is the gestalt perception system in the 
brain has an emotional reaction to some entity (in this case D) 
and the part specialised in articulation of ideas (that is also 
prone to confabulation) comes up with a reason to explain why.  
But the feeling is primary, and the words just justify the 
feeling (since cognitive dissonance is uncomfortable).

The best recent example of this phenomenon was the hysteria over 
how the dollar was going to collapse, and anyone with any brain 
simply had to own precious metals and real assets + emerging 
market currencies.

It didn't quite play out that way, and it wasn't hard to figure 
that out at the time.  (Timing was the hard part):

Anyway, once you start to understand this phenomenon you see it 
everywhere.  I do believe that's in play with regards to D.  And 
that's why it really doesn't matter what the naysayers believe - 
the ones you want to focus on pleasing are those who are 
favourably disposed towards D anyway and just need to understand 
the case for it better, or have one or two missing things 
completed.
