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."
