 - well, it is an unfortunately flawed  introduction to the science.
Isn't it so much nicer when examples actually  *illustrate*  the
problems that every expert will recognize? instead of failing to show
them, because of inadequacy of the experiment?  The Canadian trial was
large enough to show the point, just barely.

The first set.  There were 33 subjects, but only 11 were in the
condition ("vote for Gore") where an error is created by the layout --
from several examples, it shows  at a 5% rate, among people who (say)
may have problems with vision, etc., and are not primed for a quiz on
alertness.  5% gives about a 50-50 chance of seeing it in the test.
Oh, 5% error, that would imply that more than 10,000 Gore-votes were
omitted.  (The margin for not-having an automatic recount was about
2900.)  So maybe the rate is less than 5%.
