I will say this without meaning to be at all condescending or impolite,
but you have made an enormously straightforward Experimental Design 101
mistake here (and Michael Shermer, if he is referring to this particular
case, is even more guilty of doing so).
If someone is able to influence an experiment in such a way was to make
the number of hits consistently below chance, they are doing something
just as paranormal as someone who makes them come out above chance. If
psi is not real, neither the sheep nor the goats should be able to have
*any* consistent effect on the number of hits!
They give these kinds of problems to first year psychology
undergraduates to trick them, in their statistical design of experiments
