Jean M. Twenge, Ph.D., is the leading academic expert on generational differences, including generations at work, trends in mental health, and the impacts of smartphones and social media on kids, teens, and young adults. Her magnum opus, Generations: The Real Differences between Gen Z, Millennials, Gen X, Boomers and Silents — and What They Mean for America’s Future was named one of the best books of 2023 by Amazon. Her Atlantic piece Have Smartphones Destroyed a Generation?, an excerpt of her 2017 book iGen, was among the first to argue that adolescent mental health was deteriorating because teens were spending more time online. Dr. Twenge’s talks have delighted and enlightened audiences across many fields, from parents to teachers to corporate executives to investors. Her presentations are based on empirical data on 42 million people and sweetened with plenty of humor, images, and graphs.
