Research and Surveys

Shaunti Feldhahn: Researcher


A Harvard graduate and former Wall Street analyst, Shaunti Feldhahn uses her analytical skill to conduct applied research – that is, research aimed at identifying practical solutions to common problems.

For more than twenty years, she –often with her husband, Jeff — has conducted carefully designed, nationally representative surveys to uncover the little things that make a big difference in people’s lives. And from millions of readers, the results are in: It’s working.

“I feel like we’re normal,” or “this book revolutionized my marriage,” are common refrains from readers. Shaunti’s research leads to true transformation.

What’s happening now

Her current research project is in the early stages of examining targeted solutions for how the church could be a high-leverage part of the solution to the mental health crisis in America.
