In “Cognitive Dissonance: The Hidden Barrier to Learning and Change,” Dr. Tammy L. Hodo explores how deeply rooted beliefs shape our ability to learn, adapt, and connect across differences. Drawing on psychology and sociology, she reveals how conflicting ideas often trigger discomfort that prevents people from accepting new truths—especially about race, identity, and social systems. In a society still divided by neighborhoods, schools, and socioeconomic status, understanding cognitive dissonance is essential to disrupting bias and fostering genuine growth. Dr. Hodo challenges us to confront what we’ve been taught and embrace the tension of unlearning as a path toward progress and inclusion. Dr. Tammy L. Hodo is the founder and CEO of All Things Diverse LLC, a consulting firm that helps organizations build inclusive, high-performing cultures through diversity, equity, and inclusion (DEI) strategies. With 20+ years in higher education and a Ph.D. in Urban Studies, she blends academic expertise and practical insight to drive institutional change. Her clients span government, corporate, and nonprofit sectors, including DEI training for cities like Jacksonville, Tampa, and Sanford, as well as federal agencies like the VA. She co-authored How to Engage in Difficult Conversations on Identity, Race, and Politics in Higher Education and is contributing chapters on healthcare and justice for a forthcoming book on Race & Ethnicity. A U.S. Navy veteran, TEDx speaker, and contributor to Vector Solutions, she creates workplace learning on microaggressions, cultural competency, and communication. Dr. Hodo helps clients align DEI with strategy and turn values into measurable outcomes. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx
