When a college athlete in 1996 met a world‑record holder who had left the faith, the athlete—later a professor—was prompted to investigate why people abandon Christianity. That personal encounter became the seed for a research project that has since mapped the patterns and triggers of deconversion.

What Traits Tend to Appear in Those Who Leave Faith?

Marriott notes that many who leave share certain personality markers: higher scores on intelligence tests, a strong openness to new experiences, and a low tolerance for authoritarian leadership. He also highlights values such as self‑determination and a high regard for pleasure as correlates that may make questioning more likely, though he stresses that these traits do not guarantee departure.

College and the Internet: Two Engines of Doubt

University life exposes students to a wide range of ideas and cultures, and the internet amplifies that exposure by providing instant access to skeptical arguments. Marriott points out that the reliability of the New Testament—especially the New Testament’s historical context—often becomes the first intellectual hurdle. When students encounter critical scholarship, the sense that their upbringing was incomplete can spark a crisis of faith.

How Parents Can Keep the Conversation Open

Instead of shutting down online exploration, Marriott suggests a “suspension of judgment” approach. Parents can listen to opposing viewpoints, assess their credibility, and then seek out Christian responses together. By engaging in joint research—examining early church fathers, historical evidence, and modern apologetics—families can turn a moment of doubt into a shared journey toward truth.
