Why We Believe: A Global Story of Faith
What if childhood poverty, trauma, and family breakups have almost no universal link to adult religious belief?
Cross-national variation in faith sharing across religious traditions
The practice of sharing one's faith is common worldwide but varies greatly by region, with the highest rates in Africa and Asia and the lowest in Europe and Japan.
Factors like age and education that predict faith sharing in the United States often show opposite or inconsistent effects in other countries, making it difficult to generalize findings globally.
Across all 22 countries studied, the strongest and only completely consistent predictor of faith sharing is religious service attendance, as more frequent attendees are more likely to share their beliefs.
This research is vital because it shatters the one-size-fits-all model of religious behavior, which has long been dominated by studies of American Christians. By revealing vast global differences, the study helps us understand the roots of religious change, dialogue, and even conflict around the world. For policymakers and global organizations, this knowledge is crucial for navigating cultural sensitivities and promoting genuine religious understanding.
“Generalizing about religious behavior is a mistake; global outreach must account for deep cultural differences in sharing faith.”
It serves as a powerful warning against generalizing: a community outreach strategy or public health campaign that works in one country might completely fail—or even backfire—in another due to these deep-seated cultural norms around faith. For all of us, this research is a reminder that our own comfort level with sharing our beliefs is shaped by our environment. Understanding this can foster more empathy and less judgment toward people from different backgrounds, whether they are more outspoken or more private about their beliefs than we are.
“Generalizing about religious behavior is a mistake; global outreach must account for deep cultural differences in sharing faith.”
Have you ever wondered why some people are so open about their spiritual beliefs, while others prefer to keep them private? A groundbreaking study asked over 200,000 people in 22 different countries a simple question: 'Do you tell others about your religion or spirituality, even if they believe differently?' The answers revealed that where you live has a massive impact on how you share your faith.
“Whether we share our deepest beliefs is not just a personal choice; it is profoundly shaped by the culture we live in.”
In countries like Tanzania, Kenya, and India, talking about one's beliefs is very common, with over 70% of people saying they do it. But in places like Japan and across Europe, it's much rarer. The United States falls somewhere in the middle, with about 37% of people sharing their faith. Interestingly, the study found that many common ideas about who shares their faith, mostly based on research in the U.
S. , don't hold true globally. For example, while less-educated Americans are more likely to share their faith, in many other countries, it's the more highly educated who do so. The only factor that was consistent everywhere was religious service attendance: people who attend services more often are more likely to talk about their beliefs. The research also uncovered a 'spillover effect.'
In highly religious countries, even people who aren't religious themselves are more likely to discuss their views. Conversely, in more secular societies, even the most devout individuals tend to be more private. This study shows that sharing our deepest beliefs isn't just a personal choice—it's deeply shaped by the culture, history, and community we live in.
In Tanzania, 83% of the population reports sharing their religious or spiritual beliefs, the highest rate among the 22 countries surveyed.
The rate of faith sharing in Tanzania is more than 20 times higher than the rate in Japan, which had the lowest rate at just 4%.
People who attend religious services more than once a week are 49 percentage points more likely to share their faith than those who never attend.
Globally, 27% of people who never attend religious services still report telling others about their religious or spiritual beliefs.

What if childhood poverty, trauma, and family breakups have almost no universal link to adult religious belief?
While 95% of people in Indonesia believe in life after death, only 21% of people in Japan do.
Surprisingly, difficult childhood experiences like abuse or feeling like an outsider can make a person more likely to believe in life after death.
In some countries, having poor health as a child is linked to experiencing more inner peace as an adult.
People in Indonesia report feeling far more grateful than people in Japan, revealing vast cultural differences in this powerful emotion.
Across 22 countries, belief in God, gods, or spiritual forces ranges from a staggering 100% in Egypt to just 20% in Japan.
