Celia Gaertig is an Assistant Professor of Marketing at the Haas School of Business at the University of California, Berkeley. She is a behavioral marketing researcher with research interests in how uncertainty shapes the way consumers think , decide, and act. Her research challenges common assumptions about uncertainty in communication and persuasion. For example, contrary to the conventional wisdom that advisors need to offer certainty to be persuasive, her research shows that uncertainty is not always penalized - and can sometimes increase credibility or influence. She also studies how people incorporate information in their decisions under uncertainty and uncovers strategies that reduce bias. This includes her research on advice taking, anchoring, and the wisdom of the inner crowd. At Berkeley Haas, Celia teaches courses on Decision Making to both MBAs and undergraduate students. Her publications are listed below and her CV is available here. Publications (updated April 2025): Gaertig, C., & Simmons, J. (forthcoming).
