Adam Alter is the author of the New York Times bestseller ‘Drunk Tank Pink: And Other Unexpected Forces That Shape How We Think, Feel, and Behave’, which examines how the world shape our thoughts and feelings beyond our control. I met up with him at NYU Stern, where he is an Associate Professor of Marketing with an affiliated appointment in the New York University Psychology Department. We spoke about his research on judgment and decision-making and social psychology, as well as his new book, which asks why so many people today are addicted to so many behaviors, from incessant smart phone and internet usage to video game playing and online shopping.
