I did miss them.  Thanks for pointing them out.  There you write:

It seems to me that your arguments there would have the same force if you just
used the phrase "intellectual consensus" and dropped adding "science" 
modifiers.
The specific mechanism you praise is criticism, but this is mostly just what
happens to intellectual experts in general.

Now perhaps in some areas criticism is stronger than in others.  It is not
at all clear that this would be due to differing social institutions, rather
than to other differing factors.  But regardless of the exact reason for the
difference, should one prefer experts from the stronger-criticism 
areas?  You said:

Now isn't preferring high-criticism experts just another way to decide which
experts should be counted?   If the experts in some area think they do just
find with less criticism, why should you think they are wrong?
