Theodore P. Hill asks his mathematics students at the
Georgia Institute
of Technology to go home and either flip a coin 200
times and record the
results, or merely pretend to flip a coin and fake 200
results.
The following day he quickly scans the
homework data,
and to the students' amazement, he easily fingers
nearly all those who
faked their tosses.
"The truth is," he said in an interview
with the New
York Times, "most people don't know the real
odds of such an exercise,
so they can't fake data convincingly."
