As it absorbs record numbers of new immigrants, the U.S. faces critical questions: is it better to promote a unifying, shared identity that transcends ethnic differences or to foster a multicultural salad of distinct group identities? Is it better to minimize ethnic distinctions or to accentuate them with diversity initiatives and ethnic preferences? Out of the Melting Pot, Into the Fire takes a global, historical perspective to address these questions, examining how societies, from ancient Rome to modern Rwanda, have dealt with them. It provides essential analysis and data for America and other countries that are contemplating an increasingly multiethnic future. Shermer and Heycke discuss: • melting pots • culture • multiculturalism • identity politics • cancel culture • cultural appropriation • Critical Race Theory • Affirmative Action • why group preferences tend to last forever • human nature and factionalism • how official recognition and group preferences exacerbate group divisiveness • how group identification is fluid and contextual Jens Heycke was educated in Economics and Near Eastern Studies at the University of Chicago, the London School of Economics, and Princeton University.
