In 1919, one of the deadliest racial conflicts in the country occurred in Elaine, Arkansas. Historians still do not know how many people died during the Elaine Massacre. Barclay Key, associate professor of history at the University of Arkansas at Little Rock, and students in his “Age of Reform” class searched U.S. census records during to try to identify potential victims of the Elaine Massacre.
Researchers from the University of Arkansas at Little Rock are investigating how opinions are formed and manipulated in an artificial population. They set up a simulation demonstrating how the opinions of the artificial population are driven by intergroup dynamics. In the simulation, the subjects modify their opinions based on whether the person who gives the opinion is a part of the in-group (us) or out-group (them).
