My guest today is Jean Twenge. Jean is a psychologist, author, and professor of psychology at San Diego State University. She's best known for her research on generational differences. Her book, "Generation Me", dealt with millennials. Her book, "iGen", which is how I first encountered her, deals with Gen Z. Now she's back with a massive new book called "Generations: The Real Differences Between Gen Z, Millennials, Gen X, Boomers, and Silents―and What They Mean for America's Future" In this episode, we talk about all the differences between the various generations - differences in happiness, suicide rates, drinking behavior, personality traits like narcissism, attitudes towards love and marriage and more. We also talk about the technological and cultural trends that caused these generational changes. I hope you enjoy this conversation as much as I did.
