Why do we keep confessing the same sins over and over? Neuroscience has discovered that the brain physically changes based on what we repeatedly do, and St. Augustine described the exact same experience 1,600 years ago. In this episode we look at the famous study of London taxi drivers’ brains, how habit loops, cues, and dopamine work, why your phone is designed to be hard to put down, and what the Church has always taught about vice, virtue, and grace.

You’ll learn why “21 days to form a habit” is a myth, what a real study found instead, what researchers saw in the brains of praying nuns, and a practical five-step plan for breaking a sin habit, including St. Ignatius’s particular examen.

Your brain was made to be renewed.

Scripture referenced: Romans 7 and 12.
