Center for Organizational Research and Education

The Center for Organizational Research and Education (CORE), formerly the Center for Consumer Freedom (CCF) and prior to that the Guest Choice Network, is an American non-profit entity founded by Richard Berman. It describes itself as "dedicated to protecting consumer choices and promoting common sense."

Projects and campaigns of CORE include Humane Watch, a watchdog of the Humane Society of the United States; the Environmental Policy Alliance, which criticizes environmental activists; and Activist Facts, a site dedicated to tracking tax-exempt nonprofits.

The organization defends the alcohol, meat, and tobacco industries and has been critical of organizations including the Centers for Disease Control and Prevention, the Center for Science in the Public Interest, Mothers Against Drunk Driving, the Humane Society of the United States, People for the Ethical Treatment of Animals, and the Physicians Committee for Responsible Medicine.

Experts on non-profit law have questioned the validity of the group's non-profit status in The Chronicle of Philanthropy and other publications, while others, including political commentator Rachel Maddow and author Michael Pollan, have treated the group as an entity that specializes in astroturfing.
