# The McLanahan Research Does Not Prove What Watchtower Thinks It Proves

*Family structure matters, but intact marriage is not a denominational trademark*

## Doorstep Question

> "The Watchtower sometimes cites sociology to argue that JW families are measurably healthier. But the research most often cited — Sara McLanahan's Growing Up with a Single Parent — actually finds that intact-marriage outcomes are shared by every tradition with intact marriages, not specific to one denomination. Can I show you what the research actually says?"

## JW Claim

Jehovah's Witnesses sometimes cite family-structure sociology — most commonly Sara
McLanahan's work on single-parent households — to argue that the low Witness
divorce rate produces measurably better outcomes for children and therefore
evidences Jehovah's blessing on the organisation. The implicit logic is: (1) the
research shows intact families produce better outcomes; (2) JWs have unusually
high marriage stability; (3) therefore JW children have measurably better
outcomes; (4) therefore the Watchtower bears the good fruit Jesus spoke of in
Matthew 7.

## Strategy

This is a quiet, precise argument and it rewards a Witness who genuinely values evidence. Do not attack the research — affirm it. McLanahan's finding is real and uncontroversial: children in intact two-parent families, on average, do better across many measures than children in single-parent households. Every mainstream Christian tradition that values lifelong marriage shares in that finding. The problem is not the research; it is the inference. McLanahan's work does not compare JW families to Baptist families or Catholic families — it compares intact families to single-parent families, full stop. Her own published work on the drivers of family stability (the Fragile Families project, 2002 and later) identifies *economic factors* — employment, income, education — as the primary predictors, not religious intensity or denomination. So the research cannot be used to elevate one church above another. If the Witness invokes McLanahan for denominational credit, they are stretching the data past its actual conclusion. Then introduce the second problem: JW marriage stability cannot be taken at face value because of the statistical artefact (see 138-jw-divorce-statistical-artifact) — disfellowshipping removes people from the "married Witnesses" denominator before divorce can be counted against it. And the third problem: a 34 percent retention rate (Pew's 2014 Religious Landscape Study) means the children the research is supposed to be measuring have largely left the organisation as adults. If McLanahan's finding is that intact families produce durable adult outcomes, then the Pew retention data is the McLanahan test applied honestly to the Watchtower — and it fails. Close gently: "I am not dismissing the research. I am saying the research does not prove what the brochure says it proves. Can we walk through it together?"

## Key Insight

Sara McLanahan's Growing Up with a Single Parent documents a general finding about family structure that applies to every tradition with intact marriages. It cannot be used for denominational credit without overstepping the study's own conclusions. And when the research is applied honestly to the Watchtower via retention data and the disfellowshipping artefact, the inference runs the opposite direction from the brochure.

## JW Responses & Counters

### Response 1

**JW says:** "The research shows intact families do better, and we have intact families. What more do you need?"

**Counter:** You are right that the research shows intact families do better. I am not disputing McLanahan's finding — I think it is solid. But the finding is about *family structure*, not about one religion's version of it. Every denomination that values lifelong marriage — Catholic, Orthodox, confessional Protestant — shares in the same outcome curve. McLanahan does not conclude that Witnesses specifically produce better children; she concludes that children from intact households outperform children from fractured households on average. That is a universal finding, not a denominational trademark. The question then is whether the Watchtower's stability is what it appears to be, and whether the children raised in those stable homes actually stay — the Pew data says 66 percent of them no longer identify as Witnesses as adults.

### Response 2

**JW says:** "McLanahan is a respected Princeton researcher — are you saying she is wrong?"

**Counter:** No — the opposite. She is a respected researcher and her findings are solid. I am asking that her findings be quoted accurately. Her later work through the Fragile Families project at Princeton (2002 onward) identifies the main drivers of family stability as economic — employment, income, education, neighbourhood — not religious denomination. If the Watchtower brochure implies that she found JW families to be unusually beneficial, that goes beyond anything she actually published. She does not test religion as a primary variable at all. Quoting her accurately helps your argument rather than weakens it, but it also means the argument cannot give the Watchtower a denominational advantage she never measured.

### Response 3

**JW says:** "But we do have a very low divorce rate. The statistics prove it."

**Counter:** The reported divorce rate is real, but it is a composite of two things: genuine marital stability and a statistical artefact caused by disfellowshipping. When a Witness is disfellowshipped — for reasons other than adultery as well as adultery — they are removed from the count of active married Witnesses. If their marriage then breaks down, the breakdown is not visible in the figure the organisation publishes. Some of the low rate is genuine; some is measurement. The mainstream Reformed divorce rate in the United States is broadly comparable to JW figures when you control for practicing-versus-nominal distinction (Bradley Wright's research, Brad Wilcox at National Marriage Project). Committed practicing Protestants and committed practicing Witnesses are much closer than the brochure suggests.

### Response 4

**JW says:** "Why should I trust sociology at all? Jehovah's word is enough."

**Counter:** That is a serious point and I respect it. If Jehovah's word is enough — and I agree it is — then the argument for Witness superiority cannot rest on sociology in the first place. But the Watchtower brochure on moral fruit does quote this kind of research, which means the brochure itself is appealing to a worldly data source as evidence. I am only asking that when it does appeal to research, the research be quoted fairly and applied consistently. If sociology is allowed to count for the Watchtower (McLanahan's intact-family finding), then sociology must also be allowed to count against it (Pew's 34 percent retention). You cannot cite the data when it helps you and dismiss the data when it does not.

### Response 5

**JW says:** "Our children turn out better than worldly children — I see it at the Kingdom Hall."

**Counter:** I believe you see genuinely well-formed young people in your hall, and I honour that. Here is the careful distinction. What you are comparing is not JW children to Protestant children — it is JW children to the least churched portion of the surrounding culture, which is not a fair comparison. When you compare committed-practicing Witnesses to committed-practicing confessional Protestants (not nominal or cultural Christians), the gap narrows or disappears on most measures. And the McLanahan research cannot adjudicate between those two groups — it only contrasts intact households with single-parent households. The within-Christendom question is not something McLanahan answers, and it is not something the Watchtower brochure is entitled to import from her work.

### Response 6

**JW says:** "You are just trying to relativise our moral achievement."

**Counter:** I understand why it feels that way and I want to be careful here. I am not trying to erase the genuine good I have seen in Witness families — the sobriety, the discipline, the intentionality. Those are real and I honour them. What I am trying to do is distinguish between two different claims. Claim one: Witness families are often stable and committed — yes, I will grant that. Claim two: the McLanahan research proves Witness families are measurably superior to mainstream Christian families — no, the research does not say that, and using it to prove that is overreaching. You can keep the first claim. I am just asking that the second claim not be drawn from a study that does not support it.

## What to Avoid

Do not attack the McLanahan research itself — it is solid and attacking it will make you look unscientific. Do not mock the Witness for invoking sociology. Do not overclaim the Protestant position either — committed Protestants and committed Witnesses have broadly similar marriage-stability profiles when you control for practice level. The point is narrower: the specific inference the brochure draws from McLanahan is not what McLanahan published, and the honest application of her framework to the Watchtower runs through Pew's retention data.

## Homework

Before raising this, read at least the introduction and conclusions of McLanahan and Sandefur's Growing Up with a Single Parent (1994), and skim McLanahan's "Fragile Families and the Marriage Agenda" (2002), so you can say accurately what the research compares: intact and single-parent households, not one denomination against another. Look up the Pew 2014 Religious Landscape Study (published 2015) retention figure for Jehovah's Witnesses and check it yourself. Read Matthew 7:16 within its paragraph. Practise the doorstep question aloud until it sounds like an offer to look at the research together, not a correction. Prepare for "But we do have a very low divorce rate": rehearse a gentle explanation of how disfellowshipping removes people from the count before a divorce can be recorded against it.
