John Gerzema
John Gerzema is the CEO of The Harris Poll, one of the most recognized names in American public opinion and market research. A four-time author and New York Times bestseller, he built a career turning consumer data into early warnings about cultural change, from the post-2008 values shift to the case for traditionally feminine leadership traits.
