Details

In 1999 Grinnell College students Laurelin Muir and Adam Gratch conducted an experiment for an introductory statistics class. They intentionally "lost" 140 letters in either the city of Des Moines, the town of Grinnell, or on the Grinnell College campus. Half of each sample were addressed to Friends of the Confederacy and the other half to Iowa Peaceworks. The students kept track of which letters were eventually returned.
