Abstinence only: Not teaching and calling it education

The Family Research Council trumpets abstinence only sex "education"


Promiscuity Leads the Pact

Despite the angst over fuel prices and the presidential race, rumors of a high school pregnancy pact are stealing headlines in America's largest newspapers


Yep! It's a major issue and should be treated with respect. For example, we probably shouldn't just sweep it under the rug and tell people "don't have sex, it's bad".

and prompting more parents to question what public education is teaching their children about sex.

Because we all know that the solution to any problem is ignorance!

During the 2007-08 school year, Joseph Sullivan, the principal of Massachusetts' Gloucester High School (GHS), noticed a serious spike in the number of girls who became pregnant during the school year. In an interview with Time, he admitted that the teen pregnancy rate had quadrupled at GHS, and he suspected that a group of sophomore girls agreed to "get pregnant and raise their babies together."

Interesting, if true. That would actually sound like a reasoned response to how to manage the pressures of being a parent - form a community and help each other. What would be wrong with that? Is helping each other a problem?

While the media is consumed with whether or not such a pact exists, the story raises far more troubling issues about the school's message on sexuality.

And now we get down to it! Yay!

If these students never struck an agreement, as Gloucester's Mayor Carolyn Kirk insists, we can presume at the very least that these 16-year-old girls thought it was acceptable to be sexually active and become pregnant.

God turned on the equipment to do so, right? Who are we to dispute His judgment?

And why wouldn't they? GHS's own policy encourages it.

If "encourage" means "doesn't vilify a teenager for not following bogus religious rules", then this is correct.

The school offers free on-site daycare for teen moms so that students can bring their babies to school.

As opposed to forcing the girls to drop out because they have to take care of their baby.

It also teaches "comprehensive" sex education to students in the ninth grade, just in time for high school.

So in the science classroom, we should give the kids all of the facts and let them decide. But in sex education, we should only teach them one thing and one thing only. And that thing should be the one thing that the entire species is hardwired not to do. Okay! Got it!

If the school is bending over backward to accommodate teen mothers and encouraging the promiscuity that leads to it,

Remember folks, "encourage" currently means "doesn't vilify a teenager for not following bogus religious rules". This recap courtesy of Webster! Rewriting the dictionary for over 200 years!

these girls would have no choice but to assume that premarital sex and motherhood are acceptable social norms.

Yep! No choice at all! No other places anywhere in the world that they could possibly get information about one of the largest life impacting choices they will ever make!

Parents? No way! They can't talk to them.

TV? Nope! Nothing about sex there!

Internet? Please! There's no sex on the internet! No chat rooms, no IMs, no blogs, no email, no text messages about it. Get serious!

Newspapers, magazines, libraries, et al? No way! These kids can barely read.

Friends? Yeesh! Who do you think is getting these girls pregnant?

Other family members? As if! They're all going to tell them just not to have sex!

There we go! We're fresh out of possibilities. Kids have no choice!

Sarah Brown of the National Campaign to Prevent Teen Pregnancy said, "This is not a story about sex education." Of course it is! It just happens to be a story that liberals are trying to hide, as it confirms--once again--the failure of comprehensive sex education.

Yep! Complete failure! We didn't whip the pregnant girl down the middle of the street for the offense against God of having sex?!? We all fail! Our school had the audacity to teach teenagers about the very instincts that every single human being gets when they hit puberty?!? Clearly that's a horrible idea!

Planned Parenthood celebrated when Gov. Deval Patrick (D) refused the federal funds for abstinence programs in Massachusetts schools. Had he accepted the grant and encouraged schools like GHS to use it to teach sexual restraint, the storyline in this storied fishing village might have been different.

Certainly would have been different! They still would have had sex, but with abstinence only education they would have been branded evil, lying, stinking, traitors to their community as well!

Instead schools like Gloucester insist on promoting promiscuity over abstinence in direct contradiction of the wishes of 78 percent of parents (as expressed in a 2007 Zogby poll)

Note the lack of teenagers who were polled. It's pretty easy to say "no" when you're not the one giving anything up.

Like us, these parents don't understand what's wrong with telling kids to simply say "no." Isn't that the message we give them on other dangerous activities like drug and alcohol use?

So everyone is pre-programmed with a huge smoking drive and if we all didn't smoke the human race would end? Dude, your analogy needs some serious work. Try going after something that the human body really needs - like eating, for example.

We tell them not to smoke. And unlike sex education, we don't hand them filters and say "If you're going to light up, smoke safely."

Yeah, the smoking thing still isn't working. Did you get this one out of "Sucky Analogies to Use to Try to Confuse Idiots"? Or did it come from "1001 Lousy Analogies That Won't Work At All"?

Now that public schools are starting to reap what they've sown with the "just do it" mentality, states are scrambling to accommodate kids and their poor decision-making. On teen sex, it's time to stop treating the problem and start preventing it with the only birth control that is 100% effective--abstinence.

And we're finally to the crux of the issue. Abstaining from sex is 100% effective in avoiding sex. But Abstinence Only Sex Education is utterly proven to be a completely worthless pipe dream. It fails every study that it's been subjected to. More importantly it fails the basic precept of education: That we should be teaching the next generation what we know.

Abstinence Only education is, by definition, refusing to teach the subject that is claims to teach. That, my friends, is always going to be a bad idea.

Special guest replier: Professor Richard Lenski!

Professor Richard Lenski, as both of my readers know, is an evolutionary biologist who has achieved what creationists claim is impossible - direct evidence of evolution occurring in his lab.

Faced with this horrible blow to their inane beliefs, creationists such as Andrew Schlafly, the chief moron of Conservapedia, have done what they always do when a scientist achieves a landmark breakthrough to help the human race. They attack him mercilessly and stupidly.

Now normally on the Rational Reply, I take the good time and effort to reply to the idiots and their ridiculous claims. But today, we have a special guest star. Professor Lenski himself has taken the time and trouble to reply to the ignorant, impolite, and insane demands of the Schlafly crew. So to see to it that we help the good professor "make sure that [his reply] is made publicly available through other channels", I yield the floor to him to give The Rational Reply.

Take it away Professor!




Dear Mr. Schlafly:

I tried to be polite, civil and respectful in my reply to your first email, despite its rude tone and uninformed content. Given the continued rudeness of your second email, and the willfully ignorant and slanderous content on your website, my second response will be less polite. I expect you to post my response in its entirety; if not, I will make sure that is made publicly available through other channels.

I offer this lengthy reply because I am an educator as well as a scientist. It is my sincere hope that some readers might learn something from this exchange, even if you do not.

First, it seems that reading might not be your strongest suit given your initial letter, which showed that you had not read our paper, and given subsequent conversations with your followers, in which you wrote that you still had not bothered to read our paper. You wrote: “I did skim Lenski’s paper …” If you have not even read the original paper, how do you have any basis of understanding from which to question, much less criticize, the data that are presented therein?

Second, your capacity to misinterpret and/or misrepresent facts is plain in the third request in your first letter, where you said: “In addition, there is skepticism that 3 new and useful proteins appeared in the colony around generation 20,000.” That statement was followed by a link to a news article from NewScientist that briefly reported on our work. I assumed you had simply misunderstood that article, because there is not even a mention of proteins anywhere in the news article. As I replied, “We make no such claim anywhere in our paper, nor do I think it is correct. Proteins do not ‘appear out of the blue’, in any case.” So where did your confused assertion come from? It appears to have come from one of your earlier discussions, in which an acoltye [sic] (Able806, who to his credit at least seems to have attempted to read our paper) wrote:

"I think it might be best to clarify some of Richard's work. He started his E.Coli project in 1988 and has been running the project for 20 years now; his protocols are available to the general public. The New Scientist article is not very technical but the paper at PNAS is. The change was based on one of his colonies developing the ability to absorb citrate, something not found in wild E.Coli. This occurred around 31,500 generations and is based on the development of 3 proteins in the E.Coli genome. What his future work will be is to look at what caused the development of these 3 proteins around generation 20,000 of that particular colony."

As further evidence of your inability to keep even a few simple facts straight, you later wrote the following: “It [my reply] did clarify that his claims are not as strong as some evolutionists have insisted.” But no competent biologist would, after reading our paper with any care, insist (or even suggest) that “3 new and useful proteins appeared in the colony around generation 20,000” or any similar nonsense. It is only in your letter, and in your acolyte’s confused interpretation of our paper, that I have ever seen such a claim. Am I or the reporter for NewScientist somehow responsible for the confusion that reflects your own laziness and apparent inability to distinguish between a scientific paper, a news article, and a confused summary posted by an acolyte on your own website?

Third, it is apparent to me, and many others who have followed this exchange and your on-line discussions of how to proceed, that you are not acting in good faith in requests for data. From the posted discussion on your web site, it is obvious that you lack any expertise in the relevant fields. Several of your acolytes have pointed this out to you, and that your motives are unclear or questionable at best, but you and your cronies dismissed their concerns as rants and even expelled some of them from posting on your website. [ http://rationalwiki.com/wiki/Expelled:_No_Intelligence_Allowed] Several also pointed out that I had very quickly and straightforwardly responded that the methods and data supporting the evolution of the citrate-utilization capacity are already provided in our paper. One poster in your discussions, Aaronp, wrote:

“I read Lenski's paper, and as a trained microbiologist, I thought that it was both thorough and well done. His claims are backed by good data, namely that which was presented in the figures. I went through each of the figures after Aschlafly said that they were uninformative. Actually, they are basic figures that show the population explosion of the bacterial cultures after the Cit+ mutation occurred. These figures show that the cultures increased in size and mass at a given timepoint, being able to do so because they had evolved a mechanism to utilize a new nutrient, without the assistance of helper plasmids. … Lenksi’s paper, while not the most definite I’ve seen, is still a very well-researched paper that supports its claims nicely.”

(As far as I saw, Aaronp is the only poster who asserted any expertise in microbiology.) As further evidence of the absence of good-faith discussion about our research, in the discussion thread that began even before you sent your first email to me, I counted the words “fraud” or “fraudulent” being used more than 10 times, including one acolyte, TonyT, who says bluntly that I am “clearly a fraudulent hack.” In the discussion thread that also includes comments after my first reply, the number of times those same words are used has increased to 20, with the word “hoax” also now entering the discussion. A few posters wisely counseled against such slander but that did not deter you. I must say, it is surprising that someone with a law degree would make, and allow on his website, so many nasty comments that implicitly and even explicitly impugn my integrity, and by extension that of my collaborators, without any grounds whatsoever and reflecting only your dogmatic adherence to certain beliefs.

Finally, let me now turn to our data. As I said before, the relevant methods and data about the evolution of the citrate-using bacteria are in our paper. In three places in our paper, we did say “data not shown”, which is common in scientific papers owing to limitations in page length, especially for secondary or minor points. None of the places where we made such references concern the existence of the citrate-using bacteria; they concern only certain secondary properties of those bacteria. We will gladly post those additional data on my website.

It is my impression that you seem to think we have only paper and electronic records of having seen some unusual E. coli. If we made serious errors or misrepresentations, you would surely like to find them in those records. If we did not, then – as some of your acolytes have suggested – you might assert that our records are themselves untrustworthy because, well, because you said so, I guess. But perhaps because you did not bother even to read our paper, or perhaps because you aren’t very bright, you seem not to understand that we have the actual, living bacteria that exhibit the properties reported in our paper, including both the ancestral strain used to start this long-term experiment and its evolved citrate-using descendants. In other words, it’s not that we claim to have glimpsed “a unicorn in the garden” – we have a whole population of them living in my lab! [ http://en.wikipedia.org/wiki/The_Unicorn_in_the_Garden] And lest you accuse me further of fraud, I do not literally mean that we have unicorns in the lab. Rather, I am making a literary allusion. [ http://en.wikipedia.org/wiki/Allusion]

One of your acolytes, Dr. Richard Paley, actually grasped this point. He does not appear to understand the practice and limitations of science, but at least he realizes that we have the bacteria, and that they provide “the real data that we [that’s you and your gang] need”. Here’s what this Dr. Paley had to say:

“I think there’s a great deal of misunderstanding here from the critics of Mr. Schlafly and obfuscation on the part of Prof. Lenski and his supporters. The real data that we need are not in the paper. Rather they are in the bacteria used in the experiments themselves. Prof. Lenski claims that these bacteria ‘evolved’ novel traits and that these were preceded by the evolution of ‘potentiated genotypes’, from which the traits could be ‘reevolved’ using preserved colonies from those generations. But how are we to know if these traits weren’t ‘potentiated’ by the Creator when He designed the bacteria thousands of years ago, such that they would eventually reveal themselves when the time was right? The only way this can be settled is if we have access to the genetic sequences of the bacteria colonies so that we can apply CSI techniques and determine if these ‘potentiated genotypes’ originated through blind chance or intelligence. But with the physical specimens in the hands of Darwinists, who claim they will get around to the sequencing at some unspecifed future time, how can we trust that this data will be forthcoming and forthright? Thus, Prof. Lenski et al. should supply Conservapedia, as stewards, with samples of the preserved E. coli colonies so that the data can be accessible to unbiased researchers outside of the hegemony of the Darwinian academia, even if it won’t be put to immediate examination by Mr. Schlafly. This is simply about keeping tax-payer-funded scientists honest.”

So, will we share the bacteria? Of course we will, with competent scientists. Now, if I was really mean, I might only share the ancestral strain, and let the scientists undertake the 20 years of our experiment. Or if I was only a little bit mean, maybe I’d also send the potentiated bacteria, and let the recipients then repeat the several years of incredibly pain-staking work that my superb doctoral student, Zachary Blount, performed to test some 40 trillion (40,000,000,000,000) cells, which generated 19 additional citrate-using mutants. But I’m a nice guy, at least when treated with some common courtesy, so if a competent scientist asks for them, I would even send a sample of the evolved E. coli that now grows vigorously on citrate. A competent microbiologist, perhaps requiring the assistance of a competent molecular geneticist, would readily confirm the following properties reported in our paper: (i) The ancestral strain does not grow in DM0 (zero glucose, but containing citrate), the recipe for which can be found on my web site, except leaving the glucose out of the standard recipe as stated in our paper. (ii) The evolved citrate-using strain, by contrast, grows well in that exact same medium. (iii) To confirm that the evolved strain is not some contaminating species but is, in fact, derived from the ancestral strain in our study, one could check a number of traits and genes that identify the ancestor as E. coli, and the evolved strains as a descendant thereof, as reported in our paper. (iv) One could also sequence the pykF and nadR genes in the ancestor and evolved citrate-using strains. One would find that the evolved bacteria have mutations in each of these genes. These mutations precisely match those that we reported in our previous work, and they identify the evolved citrate-using mutants as having evolved in the population designated Ara-3 of the long-term evolution experiment, as opposed to any of the other 11 populations in that experiment. And one could go on and on from there to confirm the findings in our paper, and perhaps obtain additional data of the sort that we are currently pursuing.

Before I could send anyone any bacterial strains, in order to comply with good scientific practices I would require evidence of the requesting scientist’s credentials including: (i) affiliation with an appropriate unit in some university or research center with appropriate facilities for storing (-80ÂșC freezer), handling (incubators, etc.), and disposing of bacteria (autoclave); and (ii) some evidence, such as peer-reviewed publications, that indicate that the receiving scientist knows how to work with bacteria, so that I and my university can be sure we are sending biological materials to someone that knows how to handle them. By the way, our strains are not derived from one of the pathogenic varieties of E. coli that are a frequent cause of food-borne illnesses. However, even non-pathogenic strains may cause problems for those who are immune-compromised or otherwise more vulnerable to infection. Also, my university requires that a Material Transfer Agreement be executed before we can ship any strains. That agreement would not constrain a receiving scientist from publishing his or her results. However, if an incompetent or fraudulent hack (note that I make no reference to any person, as this is strictly a hypothetical scenario, one that I doubt would occur) were to make false or misleading claims about our strains, then I’m confident that some highly qualified scientists would join the fray, examine the strains, and sort out who was right and who was wrong. That’s the way science works.

I would also generally ask what the requesting scientist intends to do with our strains. Why? It helps me to gauge the requester’s expertise. I might be able to point out useful references, for example. Moreover, as I’ve said, we are continuing our work with these strains, on multiple fronts, as explained in considerable detail in the Discussion section of our paper. I would not be happy to see our work “scooped” by another team – especially for the sake of the outstanding students and postdocs in my group who are hard at work on these fronts. However, that request to allow us to proceed, without risk of being scooped on work in which we have made a substantial investment of time and effort, would be just that: a request. In other words, we would respect PNAS policy to share those strains with any competent scientist who complied with my university’s requirements for the MTA and any other relevant legal restrictions. If any such request requires substantial time or resources (we have thousands of samples from this and many other experiments), then of course I would expect the recipient to bear those costs.

So there you have it. I know that I’ve been a bit less polite in this response than in my previous one, but I’m still behaving far more politely than you deserve given your rude, willfully ignorant, and slanderous behavior. And I’ve spent far more time responding than you deserve. However, as I said at the outset, I take education seriously, and I know some of your acolytes still have the ability and desire to think, as do many others who will read this exchange.

Sincerely,

Richard Lenski

P.S. Did you know that your own bowels harbor something like a billion (1,000,000,000) E. coli at this very moment? So remember to wash your hands after going to the toilet, as I hope your mother taught you. Simple calculations imply that there are something like 10^20 = 100,000,000,000,000,000,000 E. coli alive on our planet at any moment. Even if they divide just once per day, and given a typical mutation rate of 10^-9 or 10^-10 per base-pair per generation, then pretty much every possible double mutation would occur every day or so. That’s a lot of opportunity for evolution.

P.P.S. I hope that some readers might get a chuckle out of this story. The same Sunday (15 June 2008) that you and some of your acolytes were posting and promoting scurrilous attacks on me and our research (wasn’t that a bit disrespectful of the Sabbath?), I was in a church attending a wedding. And do you know what Old Testament lesson was read? It was Genesis 1:27-28[2], in which God created Man and Woman. It’s a very simple and lovely story, and I did not ask any questions, storm out, or demand the evidence that it happened as written at a time when science did not yet exist. I was there in the realm of spirituality and mutual respect, not confusing a house of religion for a science class or laboratory. And it was a beautiful wedding, too.

P.P.P.S. You may be unable to understand, or unwilling to accept, that evolution occurs. And yet, life evolves! [ http://en.wikipedia.org/wiki/E_pur_si_muove] From the content on your website, it is clear that you, like many others, view God as the Creator of the Universe. I respect that view. I find it baffling, however, that someone can worship God as the all-mighty Creator while, at the same time, denying even the possibility (not to mention the overwhelming evidence) that God’s Creation involved evolution. It is as though a person thinks that God must have the same limitations when it comes to creation as a person who is unable to understand, or even attempt to understand, the world in which we live. Isn’t that view insulting to God?

P.P.P.P.S. I noticed that you say that one of your favorite articles on your website is the one on “Deceit.” That article begins as follows: “Deceit is the deliberate distortion or denial of the truth with an intent to trick or fool another. Christianity and Judaism teach that deceit is wrong. For example, the Old Testament says, ‘Thou shalt not bear false witness against thy neighbor.’” You really should think more carefully about what that commandment means before you go around bearing false witness against others.

A champion comes forth!

Over at Campus Report Online, the have an interesting method of refuting scientific studies. Read on.


If getting rich is your goal, steer clear of a conservative Protestant church.

Okay, I was all set to devote my life to that church, but I want to eat, too, so thanks for the warning!

That's the absurd conclusion of a study by Duke University professor Lisa Keister, who authored "Conservative Protestants and Wealth: How Religion Perpetuates Asset Poverty" in this month's American Journal of Sociology.

Oh. So that’s what a scientific study on the matter says. And since you find that conclusion ‘absurd’ you’re going to spend lots of time analyzing why a study would come to this conclusion, refuting the data collected and will clearly show us the flaws in the study!

I can’t wait!

Keister suggests that wealth is "among the most fundamental indicators of well-being"

Fairly reasonable. It’s tough to get good medical care, housing, food, or clothing without money, so that seems like a reasonable connection.

and, according to her, the church is sorely lacking it.

But you’ll show us the Truth soon!

When comparing net worth in the year 2000, conservative Protestants (CPs) averaged $26,000 compared to $66,200 for the wider population.

Short 40 thousand dollars sounds like ‘lacking’ to me. So get cranking with the refutation already!

"[The findings] are consistent with the argument that long-term exposure to CP values, particularly during the critical childhood years when people learn to save, adversely influences asset ownership..."

Yeah, yeah, Professor Keister – if that really is your real name – we all hear your absurdities. But Tony’s about to set you straight!

Keister tries to validate the liberal stereotype of Protestants as poor, uneducated people who force their women to stay home barefoot and pregnant.

Um, Tony, she didn’t say anything about uneducated or forcing women to be barefoot and pregnant. Come on man, you’re teasing us! Start raining the brimstone on this study already!

She claims that biblical teachings are hostile to the accumulation of wealth and cites people who say that it "prevents one from knowing God."

Again…that sounds pretty reasonable. Telling people that they shouldn’t accumulate money leads to people not trying to accumulate money. And not trying to accumulate money leads to not having money.

Dude! We’re waiting here and you’re doing your Casey at the Bat impressions! Connect with that high hard one already!

Unfortunately, Keister ignores the obvious explanations,

Hold the phone!

You’re not disputing the facts found in this study?!? You’re not going after the methodology that The Keister used to base her study? You’re…agreeing with her?!?

What kind of a refutation is this?!?!?

which are that believers are more inclined to give sacrificially

Possibly true, my former champion. But you need to go demonstrate it now. Perhaps you could do a scientific study to show this like say…Professor Lisa Keister actually went and did.

and place less priority on material things.

Isn’t this exactly what Professor Keister said in her study? You know, directly agreeing with your opposition is not the way to refute her findings. I’m just saying.

In fact, as Arthur Brooks notes in his book Who Really Cares, one of the best things that could happen in the fight to reduce poverty would be for Americans to become more religiously conservative. Brooks writes, "Religious people are, inarguably, more charitable in every measurable way."

So are we talking about religious conservatism or Conservative Protestants? I’m confused here now.

In contrast to Keister's theory, most Protestants don't have an objection to riches but refuse to be defined by them.

This contrasts her theory?!?

As our Dr. Pat Fagan has pointed out, men and women of faith place a higher priority on producing human capital than financial capital.

Resulting in not having financial capital.

Keister's report seems to feed into society's notion that that success is determined by what you accumulate, rather than what people accomplish or how they serve. In the end, wealth is no more an indication of success than it is of happiness.

So in the end, you agree that they are poor, just like the professor says, but they don’t mind it.

Wow. F on the refuting, but I’ll give you a D- just for old times sake when you were once my champion. Sigh.
