> The resulting distribution was Gaussian

hey - there's a "PEAR" test using exactly this type of setup and analyzing the resulting distributions for human intentioned (i.e. "Carrie" type stuff) bias:

From http://www.princeton.edu/~pear/human_machine.html

Over the laboratory's 27-year history, thousands of such experiments, involving many millions of trials, have been performed by several hundred operators. The observed effects are usually quite small, of the order of a few parts in ten thousand on average, but they compound to highly significant statistical deviations from chance expectations.

Spooky!
