Celebrities have always played an oversized role in our culture, and there’s nothing new about them using their star power to endorse ideas or products. But we now live in a time in which mass media consumption is greater than ever before, and the celebrities we revere are now at our fingertips, often only tweet away. This constant bombardment of celebrity culture is proving to have a greater impact on how we live our lives than we may even realize. Even if you aim to ignore celebrity endorsement, the ripple effects in our hyper-connected world are often unavoidable.

This week on Point of inquiry, Lindsay Beyerstein chats with Tim Caulfield, law professor in the School of Public Health at the University of Alberta, as well as the Canada Research Chair in Health Law and Policy. Caulfield is here to discuss his newest public health book, Is Gwyneth Paltrow Wrong About Everything?: When Celebrity Culture and Science Clash. Caulfield’s research provides new insight into just how much of our well-being is at the mercy of our favorite stars.
