I’ll be honest: I came to this book as a proudly card-carrying Gen Xer—raised on hose water and benign neglect, deeply relieved that my childhood existed in a mercifully undocumented pre-internet era. I was raised by Boomers and the Greatest Generation, professionally shaped by Boomers, and have spent no small amount of time genuinely puzzled by the Millennials and Gen Zers in my orbit, suppressing a grumpy in my day impulse more often than I’d like to admit.

So yes, I had some skin in this game.

What I appreciated most about Dr. Twenge’s approach is what she doesn’t do—she avoids the sweeping generalizations that so often make generational discourse feel reductive and tiresome. Instead, she grounds her observations in data analysis spanning 39 million people across decades of national surveys, exploring shifts in attitudes around gender, mental health, politics, sexuality, and more with genuine nuance.

Each generational section opens with a delightful snapshot: most popular names, best-known celebrities (I recognized absolutely no one from the Polars, for the record). Major events like 9/11 and the COVID pandemic are examined through the lens of every living generation simultaneously—a framing that illuminated how differently the same moment lands depending on where you are in life.

The book closes with a look ahead: what adaptations will older generations need to make, and how will younger ones reshape the workforce and society? It’s a fitting ending for a book that kept me thinking and reflecting long after I put it down.

Readers of every generation will find something here to expand their perspectives—whether you’re trying to understand your parents, your coworkers, or your kids. I was, in short, intellectually enraptured.
