Chastity Pledge Study "Deliberately" Skewed to make Programs Appear Ineffectual
WASHINGTON, June 16, 2005 – A so-called scientific analysis of the efficacy of abstinence pledges that concluded that young people who make pledges of abstinence were at equal risk for sexually transmitted disease (STD) and more likely to engage in anal and oral sex has been criticized as “deliberately” misleading, “inaccurate,” and “junk science.”
The Heritage Foundation’s Robert Rector and Dr. Kirk Johnson re-examined the data and claims as presented by professors Peter Bearman and Hanna Bruckner in the April 2005 issue of the Journal of Adolescent Health, concluding that “Bearman and Bruckner’s conclusions were inaccurate . . . Moreover, in crucial respects they deliberately misled the press and public.”
Explaining the deliberate misrepresentation of the facts, Rector and Johnson point out that Bearman and Bruckner “culled through the Add Health sample looking for tiny sub-groups of pledgers with higher risk behaviours,” then describing the high-risk behaviours of these tiny subgroups, allowing the press to draw their own conclusions, by inferring “that they are talking about pledgers in general.”
“The centerpiece of their argument about pledgers and heightened sexual risk activity is a small group of pledgers who engaged in anal sex without vaginal sex,” Rector and Johnson explain. “This ‘risk group’ consists of 21 persons out of a sample of 14,116. Bearman and Bruckner focus on this microscopic group while deliberately failing to inform their audience of the obvious and critical fact that pledgers as a whole are substantially less likely to engage in anal sex when compared to non-pledgers.”
“This tactic is akin to finding a small rocky island in the middle of the ocean, describing the island in detail without describing the surrounding ocean, and then suggesting that the ocean is dry and rocky,” they add. “It is junk science, a willful deception of the American public.”
Rector and Johnson conclude that virginity pledgers are substantially more likely to not engage in risky sexual behaviours, and that those who do break the pledge are still less likely than non-pledgers to engage in more risky anal or oral sex – a direct contradiction to the supposed conclusions reached by Bearman and Bruckner.
“Compared to non-pledgers from the same social backgrounds, pledgers have far fewer sex partners,”Rector and Johnson conclude. “Pledgers are also less likely to engage in sex while in high school, less likely to experience teen pregnancy, less likely to have a child out-of-wedlock, less likely to have children in their teen and young adult years, and less likely to engage in non-marital sex as young adults.”

You mean to tell me the Heritage Foundation said it was so? Well, then it must be true. Ban condoms! Close abortion clinics! The Heritage Foundation has spoken!

I'm beyond shocked that the Heritage Foundation would dispute the findings. Almost as shocked as Ben liking Texas, Christians believing in Jesus, there being clouds in the sky or people breathing air.

There was an intersting article in the paper here. Someone conducted a survey in a number of countries as to whether or not people thought that religious leaders should be allowed to attempt to influence politics. In Europe generally 12 - 25% said "yes", but in the US about 35% said "yes". The conclusion of the newspaper article? "Americans Favor Religious Leaders to Influence in Politics"!

Was this study ever published in a peer reviewed journal? were actual figures ever published?

I hate crap science and reporting
But on the pledge thing . . . Would it be a big suprise that people who say they will not have sex will have less sex than those who won't say that??
Or are most of the pledgers pressured by family to sign up so their behavior approximates that of youth generally

Not in this format, no. They didn't break the numbers down like they did here, since that casts doubts on the validity of their argument when they base their case on 21 people in a sample. Hardly representative. |
Well, you know, without an actual article to read I can't really analyse the validity of its conclusions. First you say that the sample size was over 14,000, then you say that only 21 were studied. I don't know what you mean. Were the 14000 studied, or only 21 chosen out of a potential population of 14000? Was it that only 21 out of 14000 decided to go along with the pledge? Were 14000 enrolled into the study with some pledging and others not, and if so how many were in each group? Was it that only 21 of the whole group were tested for STDs?

Hmmm. That doesn't seem to jive with what the study really says, though:

Bearman and Bruckner in March 2004 at the 2004 National STD Prevention Conference in Philadelphia presented their findings that teens who make abstinence pledges have similar rates of STDs as teens who have not made pledges. The study -- also based on data from the NLSAH -- found that, although teens who made the pledges had sexual intercourse an average of 18 months later than teens who did not take a pledge and averaged fewer sexual partners overall, they had similar rates of STDs. In addition, the study found that pledgers were much less likely to use contraception the first time they had sex and also were less likely than other teens to have undergone STD testing and know their STD status, which could increase their risk of STD transmission to sexual partners (Kaiser Daily Reproductive Health Report, 3/10/04). Of the 777 teens who reported being virginity pledgers throughout the course of the study, 4.6% had trichomoniasis, chlamydia or gonorrhea. Of the 1,622 who reported pledge to remain abstinent at some point during the study, 6.4% had one of the STDs. Of the 9,072 teens who did not ever make a virginity pledge, 6.9% had one of the STDs (Wetzstein, Washington Times, 3/19). The study did not reveal significant geographical differences but did show that minorities were "far more likely" to have an STD, according to the Post. About 25% of African-American girls had at least one STD in 2002, the study found (Washington Post, 3/19). |
Bearman and Bruckner divided it into three categories asked to take a pledge over a period of time: Those who never took a pledge, those who took a pledge but not consistently, and those who consistently did so. So they certainly didn't lump the "wafflers" in with the consistent pledgers. Even so, the STD rates were statistically not very different for all groups.
Heritage Foundation's gripes don't seem to really be about this conclusion, so the conclusion of the study appears to stand.

Yea.. but to call it more "risky" then normal intercourse is rather a fallacy isn't it. HIV for example is not commonly transferable in oral sex (i guess if you have a cut in your mouth perhaps). |
Funny you should mention that I was just reading a pamphlet about risk of HIV transmission. The rate of HIV transmission of various types of contact with a known HIV positive person for each episode of contact are:
Vaginal receptive: 0.1 - 0.2 %
Vaginal insertive: 0.04 - 0.14 %
Anal receptive: 0.1 - 5.0 %
Anal insertive: 0.1 - 0.3 %
Oral receptive: 0.06 %
Oral insertive: rare
