If you’ve spent time this week doomscrolling on your phone — even though you know it’s not good for you, that it ramps up anxiety and you’d be better off taking a walk or just going to bed — Emily Falk’s new book is for you.

“What We Value” is a peek behind the mental curtain. Why do our brains intend one thing and do another? Why is lasting change, even desired change, so hard? Neuroscientist Falk says it’s because our gray matter is silently making value calculations, which don’t always benefit us. If we can identify those calculations, she writes, we can harness them to make more meaningful choices.

Falk joins Kerri Miller on this week’s Big Books and Bold Ideas to explain her thesis. Along the way, they touch on the addictiveness of Minecraft, why habits — both good and bad — are so hard to change, and how a book about Benedict Cumberbatch impacted Falk’s research and life.

Guest:

• Emily Falk is a neuroscientist and a professor of communications at the University of Pennsylvania.
