Linda Tropp has been selected as a recipient of the 2018 Scientific  Impact Award from the Society of Experimental Social Psychology (SESP), which “honors the author(s) of a specific article or chapter offering a theoretical, empirical, and/or methodological contribution that has  proven highly influential over the last 25 years.” Tropp and her group of researchers spent over five years “trying to find every study on intergroup contact we could,” she says. Tropp mined more than 500 studies gathered from the 1940s  through the year 2000, which together include more than 250,000  participants from 38 countries, to conduct a “meta-analysis,” a type of research study “where you try to find  every study ever done on a particular topic, and then using statistical  methods, you combine the results from those studies to see what  they show overall,” she explains.
