§ Claim under review · Mixed
"There's a study that says couples who pray together have a very, very low divorce rate." (Most common circulating versions: "A 1997 Gallup Poll by the National Association of Marriage Enhancement showed the divorce rate among couples who pray together regularly is 1 out of 1,152, far less than 1%." Also circulates as "1 in 1,105," "1 in 1,156," "1 in 1,500," and as "a 1980 Harvard University study.")
Verdict
Unverified
Confidence
MediumSummary
The viral claim that couples who pray together divorce at a rate of 1 in 1,152, or less than one percent, cannot be traced to any real study. It circulates with different numbers in different retellings, 1,105, 1,152, 1,156 and 1,500, and no version links to an actual poll release or published paper. Harvard's library has publicly stated it found no evidence that the "1980 Harvard study" version of this statistic ever existed and calls it a contemporary legend. There is, however, genuine research in this area. A 2010 paper in the Journal of Marriage and Family found that couples who pray and worship at home together report higher relationship quality, and a large long-term study of U.S. nurses found frequent religious service attendance was linked to about 50 percent lower risk of divorce. That is a real and notable association, but it is far smaller than a near-zero divorce rate, and because these studies are observational they cannot show that prayer itself is the cause. Couples who pray together daily also tend to be highly committed and to hold strong beliefs against divorce, which likely explains much of the pattern.

Why this verdict
Evidence
The specific "1 in 1,152" statistic could not be traced to any retrievable poll release, dataset, journal article, or Gallup publication. Every source carrying it is a sermon, devotional, ministry page, or blog post, and none link to an original document. The number itself is unstable across retellings: 1,105, 1,152, 1,156 and 1,500 all circulate, which is a standard signature of an unsourced statistic.
On the "Harvard study" variant, Harvard's own library states directly that it found no evidence such a study was conducted at Harvard, could not locate it or any reference to it in scholarly literature, and considers it a contemporary legend.
The one real, retrievable study most often attached to this claim is Ellison, Burdette and Wilcox (2010) in the Journal of Marriage and Family. It used the National Survey of Religion and Family Life, a 2006 telephone survey of 2,400 working-age adults aged 18 to 59, and found that couples' in-home devotional activities and shared religious beliefs were positively linked with reported relationship quality. It measured relationship quality, not divorce.
Separately, there is genuine evidence linking religious practice to lower divorce risk, but at a far smaller magnitude. In the Nurses' Health Study cohort, among 66,444 initially married nurses followed roughly 14 years, frequent religious service attendance was associated with about 50% lower risk of divorce (95% CI: 32% to 63%). Reviewing this literature, VanderWeele notes married couples who attend services are roughly 30 to 50 percent less likely to divorce than those who do not.
Findings
✓ What's accurate 3
- Real peer-reviewed research does find that shared religious practice, including in-home prayer and devotional activity, is associated with higher reported relationship quality.
- Real prospective research links frequent religious service attendance to meaningfully lower divorce risk, roughly 30 to 50 percent lower in the literature.
- The phrase "couples who pray together stay together" points in a direction the evidence broadly supports, at the level of association.
≈ What's misleading 6
- Fabrication or unverifiable sourcing: the specific "1 in 1,152" figure has no locatable primary source. The "1980 Harvard study" version is explicitly rejected by Harvard's library.
- Exaggeration: a real effect of roughly 30 to 50 percent lower divorce risk is inflated into a divorce rate below 0.1 percent, an effect size unlike anything in family sociology.
- Unsupported causal inference: the claim implies prayer causes marital durability. The underlying studies are observational. Couples who pray together daily are already unusually committed, religiously homogamous, and hold strong anti-divorce norms. Those factors plausibly drive both the praying and the staying.
- Outcome swap: the 2010 study most often cited alongside the number measured relationship quality and satisfaction, not divorce.
- Inflated baseline: the figure is usually contrasted against "50% of marriages end in divorce," itself a contested and likely overstated benchmark, which widens the apparent gap.
- Loaded framing: sermon versions describe this as "proven" and as a way to "divorce-proof" your marriage. No cited evidence supports that level of certainty.
? What's uncertain 3
- Whether Gallup ever fielded a poll producing any such number. No Gallup release was located, and I could not complete a direct check of Gallup's own archive within this session.
- Whether the National Association of Marriage Enhancement ever published a methodology for its figure. No such document was found.
- The true independent effect of couple prayer specifically, separated from church attendance, shared beliefs, and general relationship commitment. Existing designs cannot cleanly isolate it.
