About the Authors

Since receiving his University of Iowa Ph.D., David G. Myers has professed psychology at Michigan’s Hope College. Hope College students have invited him to be their commencement speaker and voted him “outstanding professor.”

With support from National Science Foundation grants, Myers’ research has appeared in some three dozen scientific peri- odicals, including Science, the American Scientist, Psychological Science, and the American Psychologist.

He has also communicated psychological science through articles in four dozen magazines, from Today’s Education to Scientific American, and through his seventeen books, including The Pursuit of Happiness and Intuition: Its Powers and Perils.

Myers’ research and writings have been recognized by the Gordon Allport Prize, by an “honored scientist” award from the Federa- tion of Associations in the Brain and Behavioral Sciences, and by the Award for Distinguished Service on Behalf of Personality- Social Psychology.

He has chaired his city’s Human Relations Commission, helped found a center for families in poverty, and spoken to hun- dreds of college and community groups. In recognition of his efforts to transform the way America provides assistive listening for people with hearing loss (see hearingloop.org), he has received awards from the American Academy of Audiology, the Hearing Loss Association of America, and the hearing industry.

David and Carol Myers have three children and one grandchild.

As Professor of Psychology at San Diego State University, Jean M. Twenge has authored more than 140 scientific publications on generational differences, cultural change, social rejection, digital media use, gender roles, self-esteem, and narcissism. Her research has been covered in Time, Newsweek, The New York Times, USA Today, U.S. News and World Report, and The Washington Post, and she has been featured on Today, Good Morning America, CBS This Morning, Fox and Friends, NBC Nightly News, Dateline NBC, and National Public Radio.

Dr. Twenge has drawn on her research in her books for a broader audience, iGen: Why Today’s Super-Connected Kids Are Growing Up Less Rebellious, More Tolerant, Less Happy—And Com- pletely Unprepared for Adulthood (2017) and Generation Me: Why Today’s Young Americans Are More Confident, Assertive, Entitled— And More Miserable Than Ever Before (2nd ed., 2014). An article by Dr. Twenge in The Atlantic was nominated for a National Maga- zine Award. She frequently gives talks and seminars on genera- tional differences to audiences such as college faculty and staff, parent-teacher groups, military personnel, camp directors, and corporate executives.

Jean Twenge grew up in Minnesota and Texas. She holds a B.A. and M.A. from the University of Chicago and a Ph.D. from the University of Michigan. She completed a postdoctoral research fellowship in social psychology at Case Western Reserve University. She lives in San Diego with her husband and three daughters.
