This problem exists for any listening test. The only reason why it is more
apparent in DBTs is that DBTs clearly detect listeners who can't reliably
detect differences for whatever reason.

We've got yet another case where someone is specifically complaining about

ABX tests when in fact the problem exists for *any* listening test.  The 
reason why people don't notice this problem with sighted evalautions is
the 
fact that sighted evaluations have no means for addressing the problem of 
false positives.
